"Trickin Pickin" preformed by Doug Waterman
I’m a offshore tug captain and the trick to a good docking is a good deckhand who can grab a line for you to work into. A good deckhand is invaluable and makes you look like a king
Yup, for any boat, get a line to shore and the captain can back down on or power onto it to control the stern. Works great for embarking, too especially with on shore winds and currents.
Matthew Mueller -- Most captains don't require a person on the dock to grab a line so you can dock like a so-called king. I have a 50 ft. salmon troller and have never had a person grab a line. I live on the boat and run it by myself. I converted it to a live aboard and around 90% of the time I get it on the first try. Number 1 rule get the midship line on.
@@Ken-rk3by that’s because a good hand can throw a line from the vessel for you to work into. I’m glad you can dock your 50’ boat on your own that’s very impressive.
Agree with all you guys here. I wrote same as all of you b4 I read all your recommendations. Learning to SPRING to the dock is the most underlearned critical boat handling skill yet one of the easiest to learn. Along with using prop walk to 360* turn a vessel in its own length. I hope these guys read this and take it to heart.
Thinking back from my (limited) time on the Sacramento Delta, that reverse becomes quite necessary when you are approaching a bridge and waiting for it to raise, all the while the current is shoving you closer and closer to said bridge. If you are in a 4 knot current while approaching a bridge, and your maximum reverse speed is only 3.5 knots...you are having a *_BAD_* day.
For docking, you usually come in at a low speed (where you should have some rudder effectiveness) at an angle to the dock, start a turn to get the boat turning towards being parallel to the dock, then give it a bump of reverse to arrest the forward speed while giving it rudder to allow the stern to continue it's slow turn. When timed correctly you'll just very very gently drift towards the dock sideways far enough that someone can jump to the dock and tie a line.
A bow thruster makes manoeuvring in tight quarters a lot easier, especially in unknown waters. And NO, it's NOT just for dock queens. It's one of those tools you'll use if you have it.
Your right, dock queens and day charters. : )
I appreciate that you show the problems rather than editing them out. I lived on a cruiser for 5 years, most of the time on anchor, and overcoming issues was just part of the boat life.
I watched last night before sleep. I was impressed by all your trouble shooting and sharing your discoveries. I was most impressed when you had to disappoint your help by making a very wise decision to fix known problems before leaving the dock.
I know you don’t prefer “captain “ but how about “master”. It is a wise master who knows better than to chance others lives in his care.
How about boat owner. : )
@@SVSeeker Ok, you win. Oh BTW, the first thing that came to my mind as I was watching docking procedures, yeah bow or/and stern thrusters. Right now, your in still water. What about moving currents? Tackle that when you get there?
@@shopstuff5 We'll a day charter would sure do well with one as they have to work on a schedule. When I must go to a dock with the whole boat, it's just a matter of waiting for the wind and current to be in my favor. There are great apps for that sort of think.
It’s cool that you’re still on it and working out your systems. You’ve got a good thing going.
It’s kinda not cool making statements like “don’t go too far from the marina” to people who don’t subscribe to your method. Many have been logging miles for years on competent, proven boats with redundant and manual systems while your boat has been in your yard and on backwaters.
Hey Doug, what an absolute trimumph of creative problem solving and decision making. I salute you sir for being able to do all that AND still have the gumtion to film and edit along the way so you tell us all about it. I apprecaite it so much and can't wait to see more. Big love from the UK as always x
Love the video. The length and depth of conversation Reminds me of some of the older video’s of the construction of the boat. Trial and error, learning and problem solving
Engineering 101 class of 2022 with the seeker . Great job captain
in hydraulics,when restrict oil,rest of the oil MUST find way to reservoar...wach out for the microinjection,wery dangerous! im watcing SV for years now..thanks for every episode Doug and the rest of cruv.gretings from Srbija!!!
We'll be carful Mom. : )
Glad to see you fixed it before proceeding. Puttering around in calm water is one thing. When you are in a heavy current, wind is blowing etc., and you really need some control, that is when it will fail. You have worked too hard to have a disaster that could be prevented by just fixing it right. My 2 cents.
I enjoy these troubleshooting videos. I love to see people BUILD, solve problems and FIX stuff.
Funny. I enjoy them too. Especially that Oh Yeah, moment. : )
Hey Doug keep up the great work. Look up “prop walk” it can help or hinder depending what you’re trying to do. With your variable pitch blades it might be significant. My boat almost has no control in reverse. Good advice for parking is you want just enough speed for steerage -and consider wind and tide (sometimes tide is stronger than the wind effect). Maybe if you can get a bow line on you might be able to prop walk the stern in, good luck!
I'm know what it is but with the shroud around our propeller there is no useable prop walk. ruclips.net/video/uDss0a8K_k4/видео.html
@@SVSeeker that u do. Sometimes i use a bow spring line to help clear the stern from and too the dock. Lots of fenders 😋
Fantastic problem solving Doug!! I am inspired every time I watch one of your videos!
I learnt how my boat acts, what happens when I do this, by maneuvering around a moring bouy , it allowed me to use the same wind and tide by coming at the bouy from different directions.
Speed when turning is the key, power through the turn, use your reverse and prop walk to move the arse end one way. Use the wind, don't fight it.
HI Doug, you know you can reduce the pump pressure by reworking the relief valve spring on that pump. To much high pressure by-passing heats up and is hard on the oil. It will reduce noise and stress on the hoses also.
Oh, that is an interesting idea.
Have you done this before?
I never decreased the the pressure only have added a washer or two to increase PSI.
@@mitchhill345 Ok, thanks. I've got a spare pump so I'll just find a lighter spring. Thanks for the idea.
I was going to mention the same thing, I have done this before, turned a power steering pump into a oil scavenge pump, worked out great.
Flotsam & Jetsam: Flotsam is something that is accidentally lost overboard (such as in a shipwreck), Jetsam is stuff deliberately thrown overboard. That foam is, I believe, called Sputum.
: )
Sputum is a mix of saliva and mucus, I believe you mean spume.
Flotsam is natural like a log. Jetsam is man made
I see the need to design a bow thruster for her. :) When they developed aircraft simulators, much of what was focused on is what if X fails. You and your crew are awesome. Yes, failures are opportunities for improvement. She is well on her way to becoming an amazing vessel,
Great idea if she was going to be a marina boat. But she is not.
@@SVSeeker Seems like it would be extremely handy on the trip down the river then maybe a couple times a year after that, if that. Makes sense you'd just have the tender as a mini-tug for those uncommon scenarios.
That red fender with the 50 horse outboard works way better than any bow thruster once a capable person mans it. Bow thrusters are for practically singlehanding Capt'ns whose first mate restricts herself to cooking (if at all) after having been yelled at too many times. Maneuvering under main engine should be pretty doable with that Seeker setup, given all systems work as intended. Stripping bolts or sheering stuff when changing from forward to reverse ain't the way it's intended to work, obviously. Seatrials are for exactly that reason: breaking stuff that's underengineered, too weak or wrongly built in vicinity of land support.
Don't know if it's mentioned elsewhere but when you cut braided Line esp. Poly with a knife then torch it it can be a mess, weaken the downline braids and increase outer diameter. Just buy a cauterizing rope knife or just heat a heavy duty knife up with the torch first. Less mess, less unravel, less fuss. Oh and tape off or "Whip" off either side of the cut point first. Guarantees it won't un ravel.
Excellent addition of a pressure dump.
Most hydraulic systems should have one.
Failure is interesting, recovering from failure is fascinating, and fulfilling too. Fail more often, you'll be a better human for it.
A bow thruster may be a mighty handy addition to your vessel champ. I know if I had a sizable vessel I'd be opting for one, especially docking in tricky conditions and places
Yes, if she was going to be a dock queen. That is not her calling.
I absolutely love your engine room. It looks like a commercial tugboat! That’s the only type of engine room I would ever have on a vessel.
French Locks for driveshaft bolts. They were good enough for corvette enginerds, might help with your problem of the lock tight coming loose on the bolts. Its just a piece of sheet metal that acts like a 2 bolt linked washer and has tangs hanging out that can be bent around the bolt head to hold them from vibrating loose. Or better yet could drill the bolt heads and lock wire them to each other like nasa. Sorry about the starter woes, Still better than 2020 leftover stock
I was going to suggest the safety wire method. Its good enough for aircraft then it's good enough for drive shafts.
Yeah , I agree w/ Stephen K. Don’t embrace complexity, especially when you’re building it yourself. Best to you!
One man’s complexity is another man’s tinker toys. :)
I have always found, if you want to repair something, learn how it works first. Thanks Doug really interesting video.
I am used to manouvering a 45 foot sailing boat with a bow thruster. Sometimes, when the tide or the wind or both push us away from the dock while trying to dock longside, I enjoy using the bow thruster as rudder while in reverse. That way of entering backwards gets the rear into place first (and tied up to the dock) and the rest of the boat follows along when you thrust the bow towards the dock. During this manouver I leave the rudder in neutral position, ignoring it for steering. The thruster does all the hard work acting as a rudder in reverse
Have you considered bow thrusters on seeker. They definitely make docking much easier do although there is the cost element to consider. Loving the channel and looking forward to the next installment. Stay safe J.
Of course. Bow thrusters are great for docking in marinas. This boat is not going to be docking in marinas.
Doug!!! I should have used your discount code to get my prop. I bought one because I saw your video when you bought the red boat and mentioned it. I researched it and got one. Thanks for letting us know about it!!
Doug my favorite part of sailing and any adventure really is that feeling where you're obsessed with a problem and can't sleep can't get your mind off it. Then you solve it or resolve it and Boom! Accomplishment! Awesome work
Pass by Seeker every week driving from Tenkiller lake to downtown Tulsa for work. Gonna miss seeing her. Have fun and safe sailing sir. Been one hell of a build and learning experience for you.
If the engine dies every time you put it in gear with little pitch. The prop diameter is too big, for every inch smaller diameter you gain 200 rpm. You should be able to put the engine in gear without stalling the engine even at an idle. Also, learn which way the boat crabs when in reverse. A very common problem people have with docking is they are afraid to use quick throttle RPMs, forward and reverse. From watching you guys you are idling the engine trying to maneuver the boat. You seem to have forgotten about the tonnage of the vessel, it's not a truck so use quick throttle responses to make the boat react. Hope that helps and maybe the people on shore will quit laughing their asses off.
No, we're trying to put it in gear with too much pitch on the blade. And the prop shroud seems to kill all prop walk. And if someone is laughing it just likely they are making a series of incorrect assumptions. Let them laugh. I'll continue to learn to pilot my boat. : )
I agree. Definitely seems to be too much diameter for that Cummins. Taking an inch off may make a huge difference ( no small task).I also wonder when sailing if the shaft is rotating on the back of the transmission, if any damage will be done over time with the tail shaft spinning while the pump isn’t moving oil in the transmission.
@@SVSeeker That's a great reply. I forgot that any help you might get from prop walk is killed by the prop shroud. That's too bad.
We anchored out next to you to watch the fireworks from the marina and swim, you have a beautiful vessel.
Thanks! I'm really enjoying being a guest at the marina and Sallisaw.
I want more videos! You and diesel Creek are best on RUclips people that get s*** done and not afraid to tell you when mistakes are made.
looks awesome sitting in the water, you could install a water jet bow thruster and also have pressure deck wash down.
JT, great advice. Seeker needs a bow thruster almost more than anything else right now. Man would Doug be in heaven. And a bolt-on stern thruster would also make everything easier around a dock. Lastly, with a 74' steel boat doing everything around the dock in the slowest speed possible sure stops a lot of anxiety. Then again Seeker is like a high top sneaker from the side. Any wind will cause a problem when docking or leaving the dock.
you give the best advice about owning a boat at the beginning of the video!!
You really are an inspiration Doug, no wonder you have so many helpers willing to chip in and make it better. More power to you elbow mate. You will always succeed.
Seeker Crew are AWESOME!
Instead of focusing on the good old days you’ve created them. Awesome
Actually I know we live in a time that is much better than the good old days. We just need to recognize that and exploit it. Hell, I have the knowledge of the world at my finger tips and I can access it from almost anywhere on the planet, and there are more resources available to me than my parents ever had.
Another great video!!!
I used to run a single screw you have thrust with forward motion then reverse back and forth, right-hand screw well walk the stern over to the port side left hand to the starboard once you get close to dock lineman jumps off with spring line once spring line is on turn rutter outward put in gear forward stern will suck to dock hook up mooring lines also you must take in account for wind and currant
I have a shroud around the prop. I need to do more messing with it but I don't see any prop walk at all. Certainly not enough to even overcome a gentle breeze.
In this power pitching module thicker walls where engineered to make them not fail via thread pulling out, but through bolts shearing off. They used more metal for this to fail safe :>
Some helicopter tail rotor blades have weights placed that pitch them to a preset if control is lost allowing them to still provide some directional control.
I forgot to mention how much I love your show, it's the best fun on RUclips. Your sailing life is going to be so exciting. I can't wait. Good luck Doug.
Glad you enjoy it!
She's growing more and more overbuilt, your drive train. There's maybe one or two more things you're going to run into, but that system is eventually going to have insanely high tolerances for stress. Next thing: which one is the weakest hydraulic hose/connection? You'll find out after extended motoring. Can't wait!
You want to always dock into the strongest of wind or tide, if there is any. If you get a bow spring on and motor forward you’ll push the stern OUT. Motoring against a midship line will usually pin it into the dock, if you can get one on
Actually if you're going to load cargo ya sort of want to dock with the crane side to the dock. : )
@@SVSeeker stern to or bows to is fine, but still always working into the current 👍
If the slide for the understead stays a problem you might need to think about a screw and slide to push the pitch adjustment. This type will stop the pitch from changing with the different pressure on the prop.
I would suggest Stephen K’s advice is worth considering, But I would consider installing a MaxProp Easy, if available for your characteristics. Have used on sailboats for 25 years with no failures or destruction. They’re adjustable pitch, for both forward and reverse, fairly easily adjustable in the water, and the feathering is also very dependable. They are wonderful designs and beautifully built (in Milan). Fred Hutchinson at PYI is a genius on sizing and driveline configuration. Might be worth a call. Would love to see Seeker on the move.
Robert, the COST (big letters for BIG price of a Max prop), they are a fine piece of equipment on a boa that can benefit from their feathering, but NO full-displacement boat will ever benefit. I often see people complicating their boat with unneeded gear and feathering props are expensive and not a benefit on most boats.
The goal is not to sail the boat, but rather to help the boat sail herself :) Thanks for letting us follow along. Greetings from Denmark
I like that idea.
Once we managed to draw bottom weed into the motor by cleaning the anchor in forward as we left the anchorage. The sound of the water in the exhaust was gone as the windlass finished. It clogged the strainer right up with little pieces of 3\4" of moss right under the silt layer. We don't do it anymore, or we do it in reverse if not to many people are watching 😂
So satisfying to finally get a handle on the root problem and see the system working smoothly. How long will it take before you can trust it?
Why not right away?
@@jacobpalmer9247 Because it might fail again. Instead, wait until it's done its job 1,000 times without issues.
@@davidkennedy3050 Good thing though: the homegrown solutions do have the same grey hair.
Congrats Doug!
I can't wait to see her journey to the ocean!
Love it. Bow thrusters!
Bow thrusters are for marina boats. I did not build a marina boat.
Neutral is your best friend. AND forward the propeller wash hits the rudder so u have better steerage in forward. Your a quick learner Doug
Hi Doug, to lock the Hundested to a fixed pitch, consider using (you'll have to make it) a split collar. That way it can be installed and removed fairly quickly. I think even a wedge of UHMD plastic held in the slot, won't stand up to the forces. Just a thought.
My friends ask, "why do you build it that way?" I say, "I'm Seeker inspired".
with the smaller boats im used to but even cargo boats using the ropes as leverage makes maneuvers a lot easier. like the idea at the 18 min mark. just drop the line tie it of and gently put pressure on to get tought. then just idle in forwards and it shoud just pull the ship to the dock.
Ive used Piranha Props, love em NOT SS performance but darn close and saved my lower unit one day n still got my family home
just trottle back a little bit, to take the load of the pitchchange mechanism,then its easy to make pitch change .I converted a fishing boat many years ago ,with the same kind of proppellershaft and this trick was working for me
Lovely introduction Doug, both technical and philosophical. Kinda like you my friend 😊
Another fantastic video. Thanks for taking us on the journey and problem solving out loud.
Great video Doug glad things are going great. Thanks for the shouting out Freedom 52' were making great progress. Take care!
Can't wait to see the next video. My son and I love this. It has been really cool following your progress for the last 4 years. I'm a touring musician, but would love to cross paths at some point on the road. Best of luck on your amazing journey.
Thank you Doug for pointing out the Buddist Temple. Beautiful sculpture work. Have a good week.
Actually this is a HINDU TEMPLE not Buddhist.
I admire your patience and determination.
Your prop system your individual props don't have enough cupping in their pitch look into that dug I think that'll help you a lot glad to be a service have a good day
You'll have to take that up with Dave: amzn.to/3yU6W9D
Fellow Marinor, You cannot steer a boat, such as yours, or a ship, for that matters, from the Bow, The stern becomes the Bow. Just as you thrust the stern off from a mooring you push the stern away from the dock until you are clear and put the pointy end toward the destination.
Excellent
FLOtsam just FLOats (trees, storm debris and the like, also unintentional losses from a vessel), but JETtsam is deliberately JETissoned (eg: jetsam is discarded cargo, ballast, discarded dunnage etc)
Doug, I think your video skills are actually better than your problem solving skills. You have the best shots, angels, audio, lighting and interesting content, your pacing is second to none.
I was very surprised when you went to sailing camp, it says that you actually know your limitations even though you are always pushing the limit, I guess that's how one discovers their limitations.
You are an inspiration, this how the world got built, me I just try to maintain it. But the world needs all kinds people, except for people like, you know who in Russia, I think the world could do with out people like that, Sail on, captain.
It will be interesting to see the difference between feathered and unfeathered when sailing.
Yes. I wonder how well it will work as a sea anchor.
@@SVSeeker maybe, I know lots of performance boats have them but plenty of cruising yachts don’t.
Quickly becoming my favorite channel. Just poured concrete. setting lift up soon. Old school Hondas coming soon
What an awesome way to take the win! The attitude of of "its not a failure but an education" is the best life lesson.
This is great your in the water, playing with your boat...... So much better than being on land ..... A bad day o the water is better than being in an office
Doug , great video edit keeping the subject all about the prop and maneuvering etc.
FYI Most small boats like yours the marine transmission is meant to be in neutral when sailing allowing the prop to free wheel . This also has less drag. While that not as good a full feathering, can you adjust the Hunderstate to a position where it cannot grossly over pitch so in fail mode you have a pitch on the prop you can use? Stop worri g about feathering for sailing , it what make that much difference.max 10%
Cheers Warren
Great video Doug!
When life throws you lemons ... make lemonade. 😉
Next tip is your helm has sooooo many rotations from full port to full starboard, you should be looking more for 6 to 7 rotations from lock to lock, it looks like your at about 15 turns for rudder control
That's by design. It's a factor of the size of the rudder.
The prop of a bigger boat tends to work as a wheel, at slow speed or from stopped, before the thrust kicks in, depending on which way the prop spins you can use it to your advantage. Its also why a vessel will turn faster either to port or starboard depending on the rotation of the prop.
Some boats will have prop walk. So the after end of the boat will sometimes move towards port or starboard when in reverse. If you boat has prop walk you can use it like a stern thruster.
Ur my hero....I'm a disabled vet that can no longer work so...I'm in route 40 ft 5th wheel now looking into life to the end on water
Enjoyed that and learned a lot that I will never use - as for the use of rudder and engine when manoeuvering - THAT I will use - Thanks!
23:50 "all he needs are 8 points for this dive, and he will break in to the lead." Had me laughing good.
Another great episode. I really admire your ability to take a punch and keep going.
Never even met a power steering pump before. Verry interesting. Thanks
MARK THE DEGREE OF PROP PITCH ON THE FLOOR OF THE BOAT WHERE THE UNIT RESIDES...LIKE A Compass! Great reference point.
Were putting marks beside the control handle at the helm.
Doug, I'm a retired yachtbroker and I have an extensive sailing resume. I'm 71 yrs. old and I would like to help you. First, I think you are putting too much thought into believing that the ability to change the prop pitch is important. The amount of drag you eliminate by feathering the prop is minimal. Your boat will never go fast enough to benefit from a feathering prop. If I were you I would eliminate the Hundestad (spelling?) Talk to a prop shop, not a diesel mechanic, they think they know what's going on but they generally have very little sailing experience. I think you'll find that getting rid of the Hundestad and replacing it with a regular prop shaft and a fixed pitch prop will solve a lot of problems.
That's no fun
I bet your no fun at parties.
@@thenutdriver9685 no one who understands the nuances of this conversation is. Chill
There is an issue that the engine bogs and dies when they have too much pitch on the prop and if they raise the engine rpm then put it into gear it slams into gear.
A different sized or profiled prop could probably help but that is a chunk of change for a prop that big.
Perhaps if the prop was smaller, but there is a reason why it's sized like a trawler, and you're ignoring the motor sailing advantage. But thanks for your opinion.
Always enjoy your videos Doug! Glad you are getting the kinks worked out.
Birgir Enni oi Torshavn, captain of wooden schooner 'Nordlise' showed me how to turn the ship on the spot with just propwash. May work on Seeker too: 1. Engage forward. 2. Cut power before moving forward. 3. Engage reverse. 4. Cut power before moving backward. Repeat...
nice to see you got it all rebuilt and hopefully fixed for good.
Nothing gets fixed for good. ....but it would be nice to move onto something else.
Your week systems sink your boat. Problem solve as much as you want . Have fun with that.
Cliff swallows if the tail is straight, barn swallows if the tail is forked
Half way into this I would suggest two things, fix the O-ring and put a sensor to tell you the blade setting so you can read it. Now lets see if you and I are thinking the same thing.
Boating school 101 with the seeker
Nice now all you need is an indicator that show the position in the pilot house
Oh, we just put marks beside the leaver that moves it.
Very coo,l I have two thoughts, Is the loss of speed from a fixed prop worth the reliability of a variable pitch prop?. Second, why not set up a sea water locker and remove all thru hull fitting. You will remove most all of sinking possibilities
Hopefully a future Steel Junk owner😊
For motor sailing, it's a great setup. But it's really something for you to decide, not someone else. I feel at home with it, others will see the hydraulic lines and be overwhelmed. Frankly you can weld plates of steel to a steel shaft and connect it directly to and engine and it will work so don't let it stop you.
Excellent video, thanks for sharing!
Doug, we flow 1.4 BILLION gallons per second in the St. Clair river. It is pretty consistent, but if the wind comes from the south, that slows, if its from the north, it's faster. I've dove that river on multiple occasions (think E-Ticket ride at Disney World), and the speed varies location to location based on the bottom. I've seen it at 11 knots, and I've seen it at 9 knots...in the same area. Welcome to rivers. Welcome to one of the most dangerous rivers in the USA...Now...take a 1000' freighter down it (or up it)...it's done multiple times a day. :)
Your math may be off by about three orders of magnitude, but the point is still excellent. Even the mighty Amazon, the second longest and greatest discharge river on the planet, "only" flows 55 million gallons per second. Your St. Clair flows 1.4 *million* gallons per second, which is still absolutely colossal.
@@OkammakO sorry, misread the number on my math...lol....1.3 Million gallons per second (182,000 ~ 184,000 ft^3 per second). That's the average for the entire river. Near the Blue Water Bridge is really nasty, it's a pinch point where lake Huron empties into the St. Claire, and it's cooking through there. To the new person on the river? Well, I've seen some damage to boats for sure. It's all about knowing where to be and when. Usually one hugs the Canadian side when headed up stream into the lake...especially when winds are from the north.
182,000 ft^3/s is no joke and is still flying, and having dove that river a few times I can tell you, it's freaky Fast. My wife's plant pulls water from from it and has a real-time current meter, and that thing varies from 9knots to 14knots. The water plant does as well, and they see similar numbers (their meter is further out from shore than my wifes) Crazy speeds
We have quite a few accidents and suicides on that river. People will commot suicide by jumping off the Bluewater Bridge, and many times they pop up 20 miles down river if they dont get snagged on something. People drown when they jump off the seawall, not realizing how swift that current is, they exhaust themselves trying to get back to the ladders built into the seawall and thats it for them many times. People do this all the time, but it's all about knowing how to either drop in, and wait for a ladder to come by, or knowing how to use the Eddy Currents to get back to the ladder you went in at.
Sorry about the math....math is hard...lol. no, no it isnt...I just read the number wrong....lol
You should really think about adding a prop camera, to show you the tilt of the blades as you work. It might make things easier for you and it would let you see the prop spinning as you work up the ship and get everything sorted.
Hydropower industry - We don't weld lock bolt heads directly to their base material due to vibration cracking risks on rotating parts. Instead, we weld on metal blocks to the base material that butt up flush against the bolt's flats. That way the inflexible weld material isn't transmitting vibrations from the base material to the bolt.
My late father had lots of quotes... One was about complexity. Just something else to fail... How many hours have you spent on the adjustable prop?
