Hi Paul... re your point that you didn't think you'd adjust the damper very often so mounted it on the right. My experience... generally you stiffen for high speed runs, like on the track. But try riding at low speed with a stiff damper and it'll scare you as it prevents fine steering inputs for balance... you must back it right off before leaving the track or slowing down, so I always mounted on the left to adjust on the fly according to speed. Hope this helps... with your design you could still swap sides.
since I follow you, there is so many things I learned!!! and today I did my first welding in my life. in 46 :) just broken scissors, but I think I made it. Respect Mr. Brodie!
Thanks again eh, Paul I love your design/build as you go workflow. I know for myself sometimes I get mired in the design process a bit when fabricating something but if you can get into that flow good stuff happens.
What a great day. Both of my favourite motorcycle fabricator's (+ Allen Millard) come out with fantastic episodes. Thanks for sharing what you Paul. And thank you, Mitch, for documenting it all. 👍
8:00 I must make a break. We are writing the year 2021. A man, who makes his constriction-drawings with pencil a drawing triangle is extraordinary. No CAD/CAM! That is so amazing.
If your bike is a 350 , you would probably be running M-PG(modified-pushrod gas).Record is held by H-D. And is 108.106. Weight is your friend. Gas tank should be a minimum of 1.5 gallons. You don’t want a knee slapper. Make sure your damper actually works. My Ducati 999S ran 154 years ago but the speedometer tuned off at 184. 30 MPH of wheel spin . The salt is slippery. Good luck. Next year is the 75th . See you there with my 79’ Moto Moroni 500. You can always do a better job if you have the right equipment , and you do. Enjoy your show and all the toys you’ve got.
As per rule book, the gas tank should be a MINiMUM of 5 liters or 1.32 gallons. I guess you can make it as big as you want. The place to put additional weight would have been in your swing arm. Lead or steel shot in the swing arm when it was apart or bolted on it SAFELY on the outside. My Morini is basically like your bike. It doesn’t go fast enough to justify swingarm weight. Hope my reply helps.
@@paulbrodie I know you did a bunch of work on your front wheel, but this is what I would do for a ride at Bonneville. Take the shoes,etc. out of the front wheel. Disconnect the front brake.You don’t need it anyway. Run a cable from your rear brake to your disconnected front brake. No rear foot brake. And join SCTA/BNI and get a rule book.
Clamps turned out real nice. I wouldn't have thought of using 4mm Allen bolts even though they are more than strong enough and would have used 5mm or 6mm. (even though I keep 4mm stainless Allen bolts 'in stock!) Maybe I should re-think all the overbuilding I do on stuff? Very nice of you to show it actually takes some 'science' to design things. Do draughtsmen exist any longer in the C(omputer)AD world of today? I use the same 'cardboard aided design' as it's faster for 'on the fly. ' Guy in 'Cafe Moto' Orlando spent 10 days using a computer to design a top yoke so it could be CNC cut. Simple design, probably could have made several in less than in 10 days.so it was OTT for a one off
Thank you! Yes I'm trying to be a little more minimalistic than I previously was, but not to under-design. One of my next projects will use an even smaller 3mm Allen screw...
No worries about the current crop of draftsman. Most of them have never used that yellow thing in your righthand. A T-Square makes it a little easier though, but then you need a board .
As a 1994 900SS owner I'm almost jealous of your 15° of steering either side! I actually have no idea how many degrees of steering my bike has but it doesn't look like much more than that. It's surprising how little steering angle you use on everything but the slowest parking-lot maneuvers. The only time I notice the tight steering angle available is getting the bike positioned in my overly full garage.
The Bonneville Salt Flats mandatory steering damper for all motorcycles rule is apparently wide open for interpretation. A member of the 1% steering club? "As a matter of fact, his maize and blue Triumph won’t even turn. Lackey explained that since the front tire turns 16 percent slower than the rear tire during a speed run, he locks down the steering dampers and even then the rear tire twists the bike slightly sideways as it tries to outrun the front of the bike. “You steer it with body English,” he said. At only 5-foot-1, Lackey hasn’t got much body to English with. Still, he stands tall among his fellow motorcycle riders, being in a rarefied fraternity that takes the need for speed to the edge."
paul brodie: I do believe you just gave it away. You are taking this bike to the salt flats. Aren't you? Kind of reminds me of the world's fastest Indian.
Hope you join triple Tom M in doing a vintage run at the flats with the bike. LOL! My guess is 106mph maybe 102? 19/45 may do that the 441 likes 19/47. Ti valve stuff would help.
Maybe 2022 will be the right time to head down.. On a race track (sea level) my bike would do 120mph, but salt is salt and there is altitude involved..
Thank you G Man. I actually have to remake that clamp 1.25" longer so that the damper clears the tank shell. I will make it a bit stronger so rotation is not an option.
Delrin's generic name is in short POM or "Polyoxymethylene" It's a kind of Nylon witch doesn't absorb moisture as much and machines much nicer. Wonderful stuff.
When you were making the steering stoppers. I was thinking that it would be nice if you bored the ends that rest against the fork tubes to match the same radius when the forks rest against the stops.
I find that designing in solid works or equivalent and then printing out the design 1:1 is easier that drawing the part on the metal. After printing glue the printout to metal. Accuracy of printer is within .05mm. Holes are marked with center and that means hole placement is easier and better. You also have a digital record of parts if you need to reproduce the part or sell the design. There are free design programs that are very close to solid works. Online is one of them.
Ok, so let’s say you’re building this bike for the salt flats. What class/es would the bike qualify for? And what are the current records for that/those class/es? I just wanted to use //////....
There are two different types of POM. POM-H which is also known as Delrin, and POM-C which is known typically as just acetal. They have slightly different properties, but for casual use there is no real difference except acetal is typically cheaper
hi Paul as watching your new video I wonder how you proceed to do such a main frame tube oval vertical on the fork side to oval horizontal on the back side. I peel all your video but not seen any explanation. If it's not a fab secret would you mind give me some lightnings ? Is it under press shaped ? :-D
Yes Franc, I used a hydraulic press and put the tube between (2) fairly substantial pieces of steel flat bar. It works very well; no extra, unwanted marks in the tube. In the Romax frame build, that's how I ovalized the seat tube as well, but in my arbor press.

@@domenicomonteleone3055 Hi Domenica! Thanks for watching our videos :) For brazing and making bicycles we have quite a few videos, but you just have to use your tools and make a lot of things. You will make mistakes, but learn from them, and remember, never give up! I don't think you need a lot of mathematics, but use your intuition and common sense, and you will get better at problem solving.
I was intrigued by what happened at 8:12. I've been overwhelmed by the streamer of Delrin swarf coming off the work piece before now and I thought "Paul has a technique to prevent that!" Looked like you made a spiral cut away from the chuck which I thought would then break up the swarf for subsequent cuts, but your next cut went deeper than the spiral so you still got a continuous streamer of Delrin. Is there some hidden magic behind the spiral cut?

I think it's anodized, so that means taking it all apart and putting it in the "stripping" tank. I could always spray paint it silver, but the bike has other black things, like the tires for example!
Yeh we’ve all turned a pillar drill into a pillar part spinning flail. Iv left a mole grip type welding clamp permanently next to mine with the drill vice so I have zero reasons to not use it.
not safety third, you don't want to go into a tank slapper at any speed but high speed is a funeral about to happen the first time I saw it the rider died it was a flat track race he flew over the top of the track fence/ no backdrop fence to catch him// took out a fence post bore flying over a portion of the parking lot slamming into the back windshield of a crown vicky and pushing the front bench seat into the dash. it all happened in fractions of seconds if id had blinked i would have missed the whole spectacle. it took me a second or two to even take in what just happened. it was that fast my friend was racing right alongside of him.

Yes, motorcycles can be dangerous. I only put the steering damper on because the bike might make it to Bonneville, where they are required. I road raced my Aermacchi for 5 seasons and never had one, because it was never needed. It handled beautifully and never shook its' head once, no matter how hard I pushed. Thanks for watching and commenting.
Once you drill it and retap it you'll be 0.00339" shy of full threat depth per side and many of those 1/4-28 threads will come close to lining up with the M7x1.0...... how fussy are you really?
Yes, I got my thread gauges out and 28 TPI is almost identical to 1.0mm. I did (finally) find my 7mm tap, so it was easy to rethread and fit the rod end. I can be very fussy!
Dear Paul, i'm a lurker, but i want to say you're a born and very gifted instructor. Thanks for the clarity you impart to your teaching.

How much of an advantage is a steering damper on a race bike?
It all depends on the steering characteristics of the particular race bike. Some need them, others don't.
