Nice work, I like brazing for cast iron repairs too.
I have learned so much from you, thank you for everything you’ve done, are doing, and will do!
Thanks so much, Keith - really enjoy all of your videos.
Good repair! My dad had a welding degree from Ferris State, Still one of the top schools for welding to this day. He taught me that you move the flame in an oval pattern, drawing heat away from the rod, and the torch never stops moving. And FWIW i can braze anything with good results. Excellent video.
Keith you are an amazing teacher and I love to watch your videos and *hopefully* learn something. I really appreciate your passion for restoring and repairing old machines.
Good show!
I really enjoy watching repairs like this being done. I really enjoy seeing old things brought back to life and put into service.
Hi Keith, I'll bet you have an oven for this. I have used my BBQ Grill to heat up metals for doing repairs. Doesn't get the metal red hot but hot enough to prevent stress cracks when brazing. Thanks for sharing.
Chattanooga Plow was bought by International Harvester, and International Harvester made those mills until at least the late 1930s.
Keith, thanks for another great video. What I especially appreciate is your commentary as you’re going through the process. I learn quite a bit from what you do.
Loved the video. Good repair. 2nd blanket on the way.
I can show you how to do cast iron welding, as you described, in a true welding process with cast iron rod so that it doesn't have the brittleness in the weld area you spoke of. I worked in a welding shop where cast iron welding was our speciality, so I have quite a bit of experience with both cast iron welding and brazing of cast iron!
Preheat to 800f and most cast won’t have a brittle weld zone.
Thanks for sharing
Mr. Kieth, great repair on this part. Thank you for sharing your knowledge with us all.
Was wondering when the next video on the Jimmy Diresto bandsaw will be?
Maybe cosmetically cleanup, paint & detail the Chattanooga Mill and sell it as a “wall hanger” with the proceeds going towards a more restorable mill?…
Keith, thank you for sharing your knowledge and experience! One of the other Keiths also does brazing for cast iron repair.
nicely done. I just replaced a cast iron sign post that was welded together. It split completely because is was welded together and not braised. I trust braising for cast iron, it's just like soldering.
thanks KEITH
Well I agree with the fellow there just previous MartelDuV said it just fine for me. Thanks Keith
We've had braze fixes on our farm equipment that has lasted 50 years or more. They are very strong repairs
You could easily do a Hank Hill impression, "propane and propane torch accessories.." I loved this video; thank you. Brazing is something that has been quite hit and miss for me; sometimes it works just the way I hope, other times everything goes to heck..
Golden is still in business I bought one of their egg shaped cast iron grills about 4½ years ago.
Very nice job on that casting repair.
Just a note. By looking it's hard know the size of your acetylene tank or rose bud but it's worth mentioning because acetylene becomes unstable when the flow rate is exceeded and becomes very dangerous. In other words the more flow the bigger the size of the acetylene tank needed and rose buds really draw the flow. I only mention this as it is something that can be very easily over looked by anyone and end up being catastrophic. I don't have the flow specs in front off me but it is definitely worth looking up. I enjoy your interesting videos. . . . and learn things along the way!
On big stuff like that, I always wrap it up with a WELDING blanket that wont catch on fire, and then after it's all covered one layer, I wrap it heavily in Old Comforters from Good Will or Salvation Army and let it cool slow over night - welding blankets dont always hold the heat like you'd want
Its amazing how much heat you have to put into cast to get the brass to run. I was researching how to braze cast and ran across a guy using a cutting tip and thought that is crazy, until I started, it worked really well for me too!
Keith, you might want to get an old propane or electric oven to preheat things with in the shop. If you ever got into powder coating, it would suit for that as well for smaller items.
thanks for sharing! i have heard that pop sound before in the past!
Thank you for passing on this knowledge Mr Rucker. It's a darn shame businesses don't create things that last anymore & resurrecting the really old equipment might be our only recourse when technology fails~
Sad that the Chattanooga Mill may not be restored.
When I was 12, I painted my motor scooter and baked on some of the paint in my mon's oven. Like your wife she didn't appreciate that very much either. Believe me, I never did that again.
I was waiting for the pop. Maybe heating it in an oven it might not have cracked to the edge. But more than likely it would have. I did a braze repair on a casting and postage stamped a bunch of holes to control where the crack would go. Worked really well.
If you haven't got the gear to do brazing and the broken thing is going to be trashed it is worth while to try stick welding. Sometimes it works.
Yep. Drilling the hole eliminates the stress concentration, or "stress riser" as it was called. 😁
Well done Keith.. my wife is also oven use prohibited.. Girls! what can you say.. Such a fun way to spend part of my days. thanks my friend.. I appreciate you a lot..
For your consideration Keith, I use an LP Gas fuel weed burner for preheating cast iron for braseing repairs. I start on the low setting and then up it to the higher burn temp. Gas is cheaper and I feel the broad tip gives a broader heat spot to stop cracking. It works try it.
Thanks for sharing 👍
When I was an engineer in the merchant navy we used to drill just past the end of a crack, but the longer the crack was, the larger the diameter of the drill we used. The circumference of the drill would just touch the end of the crack. We also used dye pen testing to really see how far it extended. If you used a drill dia that was too small the crack would probably propogate on again and might totally change direction. I'm sorry but after 35 years I can no longer remember the calculation for the size of drill for length of crack for the material to be repaired.
Can't Understand your wife's attitute to heating parts in the kitchen oven! (LOL)
Biscuits with a cast iron flavor is definitely an acquired taste.
Okay, then... barbecue pit!
@@ellieprice363 i love my biscuits baked in cast iron
I don’t know who needs to hear this but this is an amazing video and I enjoyed every bit of it and I am also excited to share my investment experience so far this year, I believe it will help a lot of people here that are confused on how to start the year and be productive for the year.
From my own point of view, you need to invest smartly if you need the good things of life. so far i've made over $255k in raw profits from just 6 months into the market from my diversified portfolio strategy and i believe anyone can do it you have the right strategy, mutual funds takes long time but investing smartly is the key for short term. Most of us tend to pay more attention to the shiniest position in the market to the cost of proper diversification.
My portfolio is very much diversified so it's not like i have a particular fund i invest in, plus i dont do that by myself. i follow the trades of Mrs Diana Lynn Fusco. She is a popular broker you might have heard of. I can correctly say she's worth her salt as a financial advisor as her diversification skills are top notch, because i see that in her results as my portfolio grows by averages of 10 to 15% on a monthly basis, unlike i can say for my IRA which has just been trudging along, my portfolio just mirrors what she trades and not just on some particular industries of my choosing.
Yes, exactly. It's all programmatic and automated, plus it's relatively much easier to set up and connect my accounts than creating a financial plan and drafting investment strategies myself, my account just mirrors her trades in realtime.
@@danielrichter465 How can one find and reach her, if it is possible?
@@sophiablakes Yes it is possible, make your own research and look her name up online and send her a message, she is popular for her 17 years of service as she is always featured on Bloomberg.
Did i miss something??? What ever happened to the Jimmy Diresta and stoker engine projects???
Well,mother bandsaw isn’t in the shop anymore so it’s probably up to Diresta to show the finished paint job and final assembly on it.
I thought Keith was working on the horizontal boring machine so he could machine the stoker engine? We might never know!
@@Hoaxer51 Thanks Tim... hopefully we here an update from Keith soon..
keith doesn't really do one big project at a time. sometimes other stuff takes priority.
GREAT JOB, GREAT VIDEO...
Mr. Murphy is watching you!
If you use the kitchen oven,It gives the cookies a funny taste.
Can’t have that, I need my Christmas cookies to taste good!
Also the missus may add some other "goodies" to your food that could cause you to regret using her oven in the first place.
Sounds like you need to find a kitchen stove you can wire up in the shop for brazing projects like that.
great work...excellent Keith. Learning a lot...thanks From Buenos Aires, Argentina.
Always good to see someone using a torch to weld ,It’s great to see an old art used…..
Those domestic machines are very useful. A dishwasher does a fine job of cleaning up engine internals before a rebuiltd
We had an office guy come in on the weekend and clean a carburetor in the shop's big ultrasonic cleaner. It was for electronics and used heated trichloroethane (which I think is illegal now) as the solvent. In the process of cleaning his carb, he ruined over a thousand dollars worth of filters and several hundred dollars worth of solvent. On top of that, he cost the shop quite a few hours of delay and labor in cleaning up the cleaner.
LOVE watching you braze. You are are real master!
I never got the brazing technique down, but will agree, it's very strong method. I think a lot of people that doubt brazing have probably not done it correctly..
Notification by the sandblasting contractor of the existence of the obvious crack prior to priming would have been downright gentlemanly.
Well you either grind off the primer, or grind off the rust. Ida just had them prime it.
They might not have seen it until it was primed.
Great job Keith.
Beautiful work. Thank you.
I got a question Keith. Being that you heated the whole piece up, when you flipped it over to work on other side. Did you have to reheat the whole piece again? Or it had cooled enough to be able to handle flipping over. I plan on brazing a large piece also.
Nice job. I think your brazing is as good as if not better than Aboms :) Pretty awesome how much energy was stored up in that casting before it broke the rest of the way out.
19:18 another day eh? Same outfit.
"Leaving a little evidence of repair for the next guy". I like that.
Mr pete would not ask the wife he would just wait until she went shopping. 😂
Nice!! 🙂
Keith, can braising be used to repair a structural or stress areas?
amazing👍👍👌👌
I wonder where Keith would put an oven in his shop if he got one for cheap. Maybe a professional one on a stand of sorts so he could move it around or put it outside to heat up when in use. Seems like he's had to use an oven for medium-size part heating multiple times through the years.
He could put it on casters, and store it under his welding table when not used.
Thank you for sharing. Fantastic repair. Enjoyed.👍👀
Aside from altering the original design, is there any other reason against machining the old bronze bearings and using babbit to rebuild them?
It looks like he could use a big bag of perlite or some wood ash to bury the casting in.
Great job as always
Hey Keith great job. Where did you get your heat blanket?
Do you ever use dye penetrant to check for and find the end of cracks? It's so cheap and the results usually surprise you.
That's what I was thinking too, although in this case I guess that it wouldn't have helped as it cracked anyway.
Why would you need to cast bronze bushings? Why not machine them from hollow barstock?
Have you seen the price of Bronze stock? You end up throwing a lot away.
@@johnsherborne3245 Not if one selects the bronze stock properly.
@@johncolvin2561 I think you have better suppliers available.
@@johnsherborne3245 McMaster-Carr
@@johnsherborne3245 When I make a bronze bushing, I buy thick wall tubing that can be machined to size without removing too much bronze.
Looks great! Do you ever get any of the syrup after fixing these?
Would brazing resist a coal fire on top as under a steam boiler?
0- 4:45- " There were too many things wrong with the one mill and the customer did not want to spend the money to restore it."
I was a logging contractor for a time and my wife was quite hesitant to let me use her oven to warm my leather "White" boots for waterproofing them.🙂
Nice repair.👍🏻👍🏻👍🏻
liked for algorithm
👍
Keith, i have always been told that you need to bury welded or brazed cast Iron in preheated sand. what do you think about that?
Apparently, you got the series out of the order, I didn't see the one before this.
The previous video was posted on September 16th
I saw it too.
I didn’t get the impression you didn’t like the mill.
I understood you were fighting it’s poor condition
When I used to do brazing of cast iron I would start heating like you but where the area of the crack was vee out I would sprinkle brazing flux into the vee to help stop the oxidising as you heat the cast iron also helps the brazing rod to flow easier.
987th👍
982nd actually.🙉
I have noticed that the same people that bad mouth repairs are the same people abusing the equipment beyond specified use, that being said, I dont know many people that bad mouth repairs
Please fix your mic. The audio goes in and out
The flux on brazing rods is borax. Back in the days when I took welding in trade school, our instructor told us that this coating could be purchased in a powder form from a welding supply, and for ferrous metal, laundry borax was most adequate. I've used Boraxo, and it did, in fact, work most satisfactorily. At one point, I had gotten some scrap (cheap) grandfather clock pendulums, and disassembled them for the brass rods that were in them. These were adequate for brazing rods.
I have a big box of laundry borax I bought 40 years ago and have used it to flux my gold lost wax castings. The box is gone but I still have some of that borax left.
Bryant Fry, That’s interesting, thanks for the information, sounds like a money saver!
The zinc in brass vaporizes and that vapor is toxic. Especially if working in a not so well ventilated space, stick to brazing rods known to be free of toxic, volatile, metals.
Shocked that went through the trouble of fixing the crack. I assumed these would just be more of an art piece rather than functional.
no, they are being repaired so they can be used.
My wife hates it when I degrease stuff in the downstairs basin. Women are strange 😄.
Nothing what so ever wrong with brazing if you are not trying to make an undetectable repair but I have said it before we have been repairing antique cast iron items for over 40 years and with very few exceptions we use only gas weld with REAL cast iron rod. Doing it that way pre and post heat is ultra critical,,,,, So what is the high tech way to do i?
We have a sand pit out back of the shop,,,and we dig a hole about twice the size of the part and get a charcoal fire going in it. - Then you out the part in the pit and cover it with hot burning charcoal and then cover it with fiberglass insulation....(we tru to use foil backed but you can get away with paper.
One the part is evenly heated to over 1000F we take it out (with a BobCat) and take into the shop and weld it up ; --- Then it''s back into the pit and covered up with more burning charcoal and fiberglass. We put a piece of sheetmetal over it in case of rain and leave it alone till the fire goes out and you can touch it with your bare hands. - Totally machinable and after dixying it up with a grinder and needle scaler or sometimes grit blast it is a totally undetectable repair without paint and every bit as strong as the original part. Like it never happened.
Sometimes the primitive ways are better then the $50,000 heat treat furnace.
BYW The ceramic fiber blankets are great,,,,but the way you did it when you get done fiberglass insulation woks too and doesn't cost $3500 a roll. ,,,,and finely, NiRod is for Bob Villas. No real pro would ever even think of using it except for a cheep and dirty repair - with no guarantee other then you pay in full before it leaves the shop.
Hope everyone knows NOT to respond to the scammer telegram scam that seems to follow every comment here.
Mind-boggling that RUclips appears to have no interest in counteracting this wave of spam. These comments are so easy to spot, they could implement a spam filter in a heartbeat. I can only assume that they don't want to.
Sound quality so poor for the last couple of months it is detracting interest in your video's.
Seems fine to me?
