Watched the installation of the capstan and you should be very proud....I was
I wonder when we might see the installation of the Stoker Engine?
Keith, I had to laugh a little about your mystery package. I used to own a business and we would get deliveries of materials to be worked on that included no name, number, address or instructions. We would set it aside and a month later the client would call wondering why his project wasn't done yet.
LOL !
Maybe that's the case with the Stoker Engine!
holy smokes, a simple project. Watched the capstan be installed and working. I am impressed, but not surprised, the Tally Ho people were able to take it apart put it back together and put it into service with a minimum of fuss. An impressive saga of design, building, installing and skill.
I sent that, didnt need it brazed, just need the 3/4" hole bored to 7/8"
Oops, got it brazed anyway.
Lol
What is it a piece of Clark? Interesting part!
LOL this is one of the drawbacks of being a hard industrious worker. He got the job done before he knew what it was and who it was from.
I'm sure it will get sorted. If it's not too much trouble could we have a video short of this piece fitted and working and what it does?
Hahahahaha, ya right!😉
I know the feeling of the mystery work. I've had people send me guitars worth tens of thousands of dollars with no note. I have gotten very good about reminding people to include a note in the case.
Hardest part of the job is finding out who the part gets shipped to. Another great episode Keith. Thanks for sharing!
Nice camera work. It was most interesting to see the close up view of the brazing process.
He still needs a sodium filter for his camera, like his brazing goggles, for us to see though the yellow light.
Glad I had something to watch while the hurricane/tropical storm passes over!
Leo put the capstan on the boat and they are leaving on a trip of maybe 2 or 3 months .
I saw that video, a little fine tuning and the capstan worked very well. The chain wanted to drag a little in the chain Gypsy but as they use it and the chain wears in a little bit it should work perfectly fine. Of course Leo will make something to help the chain release in the meantime. Lol
Leo has been hard to hold since the ship started floating.
Without your help he wouldn't have made it this far.
I would just like to add that all of the parts of the job that Keith and the other guys here did, work flawlessly. It sounds like the chain issue was the result of a difference in the sample chain and the actual chain that they ended up with. The folks in England did a great job as well.
@@dannyl2598 it also seemed that some of the chain links were different sizes
@@dannyl2598, It’s amazing how well everything worked together with other parts made in England and the man who designed that was definitely top tier in his field, the only issue by the sounds of it, were some of the welds on the chain links were just a bit bigger than the chain they used to design the Gypsy.
I saw the piece that was made for the casting for the capstan top and that looked like a piece of art, I wonder what happened to that. I thought Leo should display that on a table somewhere. A lot of work for one small piece of the entire project, and it fit perfectly.
Great vid as always, by the way, the capstan for Tally Ho has been installed and is working although they had to do some fettling with the gypsy as the chain supplied was very slightly wider than the one that was used to take measurements for the gypsy and some grinding was needed to make it right . Your machining was spot on without fault as expected .
There’s a very fine region between the temperature where the material is plastic enough to flow and when it starts flowing onto the floor. You sure made it look easy. Another excellent video.
Your great work on Leo’s capstan and it is fitted and working fine Keith 👏👏👏👏👏👏👍
I hope the owner shares the needed info for you. Great channel.
Now, it's a happy Monday Georgia! 😊
And a happy Monday for the rest of us...except maybe some people in Texas being visited by Hurricane Beryl.
@@peterhobson3262, Hunker down and Good luck to everyone down there!
🤣A mystery part from a mystery viewer
One of the biggest "mystery parts" on this channel is the Stoker Engine!
@@garybrenner6236 good memory I had forgotten about that
@@garybrenner6236 If I remember correctly the stoker engine was impossible to repair due to the deep cavity and limited space to rebuild the floor.
I suspect it’s been quietly and permanently laid to rest in a rusty grave.
Good morning Keith! Thanks for the videos and have a great week!
Great repair
Thank you Keith!
As long as the part isn't too big I really like silver solder in the same style you are using here. Nice mend my friend.
Great Job Keith. I love watching Fire and iron repairs.
Nice work!
Thanks Keith!
easy job well done!
Thank you for sharing.👍
Thanks Keith
❤❤❤ brazing so relaxing to watch and hear
Easy trick for fixturing broken pieces back together for brazing or welding. The video of the brazing the pulley reminded me of it but this one got me to comment. Use a firebrick to hold the pieces in the position you need when they need something to hold them in alignment. They are easy to shape with a rasp or file and you can make them in any shape you need. Unlike using metal they don't pull the heat out of the parts nearly as fast and they are reusable easily.
I saw the road tour to the bash is up now. I'm heading over there right away.
Thanks for another video. 👍👍
Once again fine work,
Thanks for sharing
"I dunno what this is, or who it's from, but it's broken and I can fix it, so i'll start there" :D
thxs for sharing...
loves watching you braze keith!
Nice job Keith. 🙂👍
Good job.
Have a great week Keith. Keep up the good work.
Good job
wonderful
Have you ever welded with a coat hanger and borax? Get wire red hot then stick into borax. Works
Back in the day, that's about all that they use in service stations and backyard garages. I've done it just for practice. It's better if you burn the varnish off first.
I've seen quite a lot of auto body repair men do that, some still do in a pinch.
Instructions unclear. The plastic just melts, drips and burns... 🔥
@@jonathanrichards593 sorry, I forgot to mention that those are for welding plastics.
Nice job Keith. I hope it finds it's way home.
I was thinking the same thing. I hope he gives us an update. 😂
I wonder if the Stoker Engine will ever find it's way home!
Some old soldiers used a BAR. Keith uses a BAV. (He never carries it though.)
Another one bites the dust
Some of the keys to a good braze is a clean surface, preheat and generally a veed gap to give enough support to provide the strength that the joint needs and slow, controlled cooling. When possible, my preference was to braze rather than arc using nickel rod. Brazing is more forgiving when in service. Make sure that all surfaces are “tinned” or wetted before filling the joint. A little reinforcement is not wrong as you can remove the “blobs” afterwards. While Keith used a flux coated rod, if available, Boraxo was an effective fluxing agent for bare rod. Believe Keith described the necessity of preheat. The important thing here was to heat the casting portion with more mass first as the smaller portion will come up to temp quickly. Do not overheat! If the casting gets “burned” you might have to start over to have clean surfaces. If you intend to reinforce the brazed joint by extending beyond the “V” then I suggest to lightly grind any surface scale to obtain good bond of the braze filler rod. Another method was using cast iron filler rod instead of brazing rod. That required rods and flux made especially for acetylene welding. However, I don’t know if that material is even produced any more. Large castings could and often were repaired by brazing. Sometimes, it was necessary to do the preparation and the construct a furnace of fire brick around the casting to allow for controlled pre and post heating and cooling of the casting. This is an overkill of explanation of Keith’s’ repair job but following the prerequisites and experience make a good for a job. Thanks Keith for all you do.
".. going to flame braze it." Sounds like a hamburger chain advertisement!
Funny!
Good
Hey Keith, I think I sent that to you. It was my femur attachment for my left leg. I been wondering where that got to.
The man of steel or maybe cast iron, ???😵💫😵💫😵💫 Oh! darn I have no idea what Iam talking about.
Thanks for the Monday morning laugh, always appreciated!
I’ve seen you do a number of these repairs. It seems like people spend a whole lot of money to have that shipped to you when maybe they could’ve just had a local welder do these bread and butter repairs? Maybe I’m not seeing something but nice job thanks.
If you ever decide to take more stabs at TIG brazing, even as learning experiences, I'd be very interested.
In this episode Keith is tricked into repairing a oart for a nuclear submarine.
Lord protect our Sailors!
Keith you was acting as if you where going to post your email address, had couple questions on lathe restoration and fixing some parts that may or may not been broken in shop/loading unloading 😅 , if Keith doesn't get this or someone else knows that email, please respond as trying to get this old machine going soonest can, thanks y'all!
Thanks , Keith, I have never seen broken cast iron being fixed. Is brazing as strong as a weld? Why use brazing rather than welding? We always learn something when we come here.
It is stronger than the casting. You normally don't weld a casting.
Hi! I can actually explain this, as Mr. Keith has done a number of brazing episodes over the years. The reason he has chosen to braze here is specifically because of the material the part is made from. Cast iron can be welded, but doing so and having it come out right is a very finicky process that requires a lot of experience in the proper technique, with specialized welding rods, and the likelihood of introducing stresses into the part that will lead to it breaking again when you try to put the part back into service is high. Mr Keith will be the first to tell you that he doesn't have that experience. He does, however, have absolutely tons of experience with brazing cast iron, so much so that he has complete confidence based on years of experience that his braze repair is likely to outlast whatever machine the repaired part belongs to, and will be stronger than the part was originally.
@@jamesmoe9188 The bronze alloy is comparable in strength to cast iron. Iron's advantage is low cost. Brazing is high temperature soldering. The base material gets hot, but does not melt. Solution effects create some of the bond. Welding melts the base material and that UNFAVORABLY alters the crystalline structure of "ordinary" cast iron. VERY hard/VERY brittle stuff, rich in ferric carbide, is created. Look into the numerous videos by Keith Rucker and Keith Fenner regarding this subject.
Also, welding cast iron is usually done with nickel welding electrodes (rod) which introduces a different metal with different characteristics, and arc welding is a violent process that causes heat related problems which the other comments have 10:42 explained.
All of Keith's repairs come with a 5:50 warranty. Meaning that after 10 minutes to 6:00, all bets are off.
My Bodges/farm fixes/repairs come with a tail light warranty, (as soon as I can't see your tail lights)... if I'm confidant it'll hold, I sometimes offer the extended 5 minute, 5 mile warranty...
❤️🔥
That's the tough part, Brazing the other side.
Wonder what the part works?🤔
Ok, so I don't know anything more about brazing than what I have seen you and Adam Booth do. How did you flip that to the inside and not melt the outside off while reheating it?
Whats the difference between welding and braising?
Welding actually melts the base metals together with the filler material.
Brazing does not melt the base metals. It uses the filler material to form a bond between the base materials. Brazing is done at lower temps than welding.
Brazing is the long standing go-to method for repairs of cast iron.
Temperature and filler material.
Good answers already to your question, Just in case here's another point.
Welding uses electric, Brazing is nearly always gas. Keith recently tried to use a Tig welder for brazing and quickly gave up on it and went back to his trusty gas blow torch.
Braising is the cooking of meat or vegetables by heating them slowly with oil and moisture in a tightly sealed vessel. Wouldn't be useful for this part at all. HTH :)
@@jonathanrichards593 There's always a fellow smartarse comedian about. Good to know in a way as even when I die my bretheren will still thrive.
Saw the comment that all that was needed was the hole enlarged. I wonder if that was ever done?
Look who that was sent from.....
I X every seam like that, just a small v running across the broken spot
I would really like someone to show me the cherry in “cherry red”. I’ve brazed, and watched a lot of videos that refer to “cherry red”, but what I see is more “Valencia orange”. Do you mean sweet cherries that are about the color of merlot, or do you mean tart cherries that are fire engine red, or do you mean Napoleon cherries that are yellow to light orange??
👌👌
Why do they say cherry red.
It's nothing like the red of a cherry.
It is simply red, more important is the sheen that the metal takes on as it reddens. Cast Iron develops a "wet" appearance when it is hot enough, that indicates it is ready for the brazing filler to be added, also the flux spreads and flows at that temperature.
Look up images of a tart pie cherry. It absolutely looks the same. You are probably thinking of a sweet Bing cherry which is more purple.
0:50 As soon as I could I got iPhone iCloud Service .. ... Pretty sure it was with iPhone 3 .. AND HoTMail email service (... pretty sure that was Windows 3....
and therefore any time I upgrade or replace my phone ... I never lose an email or a contact (or a song or a picture) ... I think I spend just under $2 a month for that service :)
I do not however make any videos :) .. So Keith has that!! :) ... ALSO it's such a good idea to put a note in EVERY package! With your address and the TO: Address and what it is (Used antique PARTS, GIFT) etc
I had an international shipment years ago where ALL the packaging got lost, the box the tape the inner box etc everything.
BUT I used one o these "wire tie-on tags" on it with all the info, the Post Office put it in their own packaging (albeit a thick plastic bag) and waived any customs and duty, AND sent the last leg of it's journey on "Next Day" Priority for us!! :)
