Broken Feed Arm for Post Drill Braze Repaired
ฝัง
- เผยแพร่เมื่อ 16 มิ.ย. 2023
- This video shows the repair I made to the 100 year old feed arm off of a post drill press. This part was broken during shipment and was a great candidate for brazing. I'll share my techniques used to fix this vintage part and get it back in serviceable condition. The brazing filler material I used is the Eutectic Super 146 XFC.

Really nice camera work on that brazing. Shows exactly how it should be done!
My wife and I really enjoy the channel!!!
Maybe invest in a small blast cabinet to do final touch ups on parts like that. A good little bead blast cleans up the areas and makes them uniform
Abom79, this was great - back in the manual machine shop working on a difficult project, instead of the new toy shop. You shine best here, and I appreciate the video!
kinda like dave richards shop, his occasional videos done in the shop he makes his money in are pretty neat, yet, why we're all there is the shop with all the belts.
Abby is doing a GREAT job as videographer!!! Good for you Abby
ANOTHER FINE SATURDAY NIGHT WITH ADAM THANKS
Missus Abom has you pegged!😂😂😂😂😂 I think it’s fun when we actually get to see a genuine smile on that normally stoic face. Keep up the great work Adam
Before ever learning to weld, I learned to braze. I still like seeing Gold!
He has the new shop with all that new fancy gear, but I still enjoy the work he does in the old shop a whole lot more.
..and I prefer the "hand work" in the old shop. New shops are great for production, but thats not why I enjoyed @Abom79's channel for so long.
Old videos of making the parking attachment and the welding table from an old lathe chuck plate were some of my faves.

I like when you work in the old shop so many good memories
Good "How To" video. The camera work is very good. Gives a nice close up to see how you do it. Thanks to both of you.
The way I was taught to braze is that the rod should melt with the tip of the inner flame is about a 1/8 inch away. I'd turn the gas down a lot more for a small part like that so you're not putting as much heat into the part and you can control the puddle better. Another way to think of it is that you're using to many amps TIG welding and it's overheating the part and pushing the puddle around.
agree 100%
Just the thing I need after a long day at work, Abom79 repairing metal, this is so relaxing!
Photography on brazing is the best I have seen.
Abby calling Adam cute made this video for me. Great video, thanks Abby and Adam.
Thanks for sharing. Still love the old shop
Thanks for the time and extra effort to put this on video; it is greatly appreciated!!
Quite a job,man.Looking forward to part 3.Thank you Adam and Abigail
you give me hope that my good enough work is good enough.
Another excelent vídeo. You have the "know how" in all of your jobs. Thank you
Nice work on the repair and the camera.
Nice job Adam you too Abbie I have a old post drill work’s good nice keeping old quality tools going thanks you two
I was wondering on how that gear was centered. You answered my question, can’t wait for the next video. Thank You, Ric
Adam I admire how you never skimp on PPE when you are welding / brazing. Always proper gloves on both hands and a good, heavy drill, long-sleeved work shirt. Likewise, Keith Rucker. So many TH-cam presenters show welding without any gloves and in a short-sleeved shirt. While I respect it's their decision to do so, I think it shows a bad example for younger viewers or others who are not aware of good PPE practices to follow.
Great camera work by Abby on the brazing techniques.
Best regards to you both from Albion Park, NSW, Australia
As someone who manages a workforce, I couldn't agree more. I tell my young guys all the time, if you want to look tough, the eyepatch you end up with will do the trick if you don't put on your safety glasses. The hearing aids though might bring that down a notch.
Adam, whatever you did at 9:25 to 11:30 was EXCELLENT! I have NEVER seen a braze filmed with such clarity, the image was perfectly exposed and nicely in focus. You (and your charming & tolerant camera person) have come a long way in videography. Thank you for letting us learn from you.
Right? Usually the camera just gets blown out and all you see is bright white.
Yes I believe Abby filmed that as the camera was not on a tripod. She has achieved excellent brazing footage previously. Abby you’re a master!
A lot of negative comments here. Looks like some are angry with Abom. It's old school traditional welding though. This guy shares his work and he doesn't need to be reminded when he makes a blunder, he doesn't hide it, he admits it and fix it. So why all this anger? Are you afraid that Abom lose his grisp because of the cnc work? No risk. Should all the videos be flawless like "workers on another level"? I feel a Tiktok syndrom is spreading.
Amen, brother…..
It's nice that hd has more than one grinder. I've tried to do this as it's much easier to grab another one than to switch back and forth. I have a several of them, and haven't paid more than $15 for any of my name brand grinders. I also have several Asian made ones, but again, I've bought them used, and repaired them.
Nice work mate. I am very excited to see you working.
Beautiful work Adam.
Ye olde shop - we like it! (especially since there are no CNC machines in sight)!
Nice, lots of ideas to up my game, thanks.
Adam you are a master of your trade.
I used to braze a lot of exhaust systems back before mig was a thing. Got pretty good at it.
Adam: you're an Artist, man! Congrats!
That was enjoyable to watch. I used to braze stellite steel on auger boring bits to the wearing edges, every day. Also brazed huge cast bull gears. Smaller cast parts like u brazed do benefit by post cooling in a powder lime box.
Great camera work on the brazing
Brazing is my favorite type of welding. The whoosh of the flame, how the metal flows. It's relaxing. Plus with just a little practice the welds can look pretty good.
...brazing is NOT "welding"-(!)
Quality repair.
Using the scaler to texture the braze is a nice touch!
I think the mix of materiales looks much better than the original cast piece! Nicely done! 👏👏
Man, that Noga clamp setup looks super handy! I've gotta get one of those.
im glad you left more material on the arm than the gear. more bronze more better
Wow everyone trashing this job? I’ve done a job like this. It was a nightmare, things shift expanding and pushes other pieces off center. I think it was great save by Adam on a part the can’t be bought. Don’t get me wrong I would love to see Adam fire up the cnc and make a new gear but he doesn’t have to it’s fixed.
Actually he said he needs to fix it.
This is Art! ❤🔥
Easily the cutest machinist on TH-cam. Hands down 😂😂😂
Very good work Adam. Very good. I like
G'day Adam.. nice job overall on the assembly & Brazing of the wheel & arm, + I like the Holder for the arm, good food for thought.
I personally would have used a slightly less aggressive flame, as in the higher pressure, which appeared to be pushing the Bronze out of the weld.
I'm glad you mentioned that you were going to true up the gear by fitting a thin walled bush.
Overall a Great Video looking forward to the finished product.
Great solution with the Noga Kant twist. Would be nice to see these parts at work 😁
Nice job!
Thanks for the video
Good repair Adam and Abby great camera work on the brazing clearly showed how both sides must be cherry red to get the bronze to flow in there and also that at that temp the hardened bronze tends to slump so it is a tricky little bugger and takes practice and more practice to deal with that fiddly balance of juggling molten bronze and un-molten bronze at the same time. An ART.
Excellent work. Even if it wasn't cast iron, the bore would likely still need modification from all the heat and movement. Part of the process, Adam!
@@SteveColluns-hm2xx Sure anything you say, question though. Why are you still here? You obviously don’t enjoy the content, and are clearly a superior machinist, so you’re wasting time here, why exactly?
VERY NICE
Most Excellent.
Nice brazing job Adam. Just a tip... an older mate (mentor) taught me how you can remove the 'glassy' flux residue from brazed joints by simply soaking in water.
Your technique during that second side may have seemed unpracticed but looked right perfect. No melt in the bottom half I noticed, except at its top, so you didn't overheat much if at all. I may need your work, too.
Thanks, it's very good job.
It difficult to are the good temp and variate to mainten this.
The picture is so nice!!!
Hello to France
Great camera work while brazing....! Just like being there watching with a pair of goggles on....! Great Content, as usual....!
I silver braze A LOT and i agree with building up the material really heavy then grind off the excess. That ensures that the material was all melted into the piece. My 2 cents anyhow. Thanks for all the great teaching.
Good job.😊. I would like to see the post drill assembled with the parts that you repaired. Thank you.
Human god level skill, thank you for sharing this with us
Oh, gosh. I’m reading all the negatives. So sorry. Please don’t let them get to you. I always learn from you even when you are struggling.
I miss these videos. The CNC stuff doesn't interest me much. I love the manual machining, and especially the repair videos. Just my opinion.
...well, "ya CAN'T please EVERYBODY!!!"
Thanks for the video,, but one thing we really need is full duplex audio,, we can hear you while you braze but no matter how loud we yell it's melting through you never hear us !!!
See you on the next one !!
I don't want to teach anything, but with small pieces I would use a smaller point for the pass on the opposite side. It's also best to use the "heat and move" technique, so you don't melt beyond the opposite solder surface. Good work
25:06 😂 you two are perfect for each other.
Wish you would turn your old shop into a machine school and give me a full ride❤
Lots of negativity in the comments again. Some positive criticism as well. Me, yes I'd have done it differently, but I would have ended up with a similar result, I use powder flux and a none fluxed rod for one. But its great to see how the likes of Rucker, Fenner and you tackle these jobs. Keep up the good work.
Cute, Cute, Cute! ! !
Great vid .. U & Abby are a dynomite-duo .
hey Abom, dont know if you know this, id assume so, but using the needle scaler in addition to cleaning up the part and putting a texture, it also reduced the stress of the cast iron after inputting so much heat to braze the part . =)
Man that’s great work. Adam’s brazing and Abby’s camerawork. I could see exactly what you were doing with the at management, truly a great piece of video work.
A+
Thanks Adam! Always able to resolve issues on broken parts. Wonderful to see the skill and talent on display. But the "can do" attitude is the key! Heard Ms. Abbey's (sp) giggle in there. What a formidable team ya'll make! Thanks for this and all your videos!!!!!!!
Another remarkable job from a cute welder as ABBEY puts it, and good looking repair also. Thanks for sharing.
I've personally never seen such aggressive grinding like you did on this specific brazing job. It's always been my understanding that less soft metal filler (brass) is better, on brazing applications since it's basically a hot gluing operation. However, I am not familiar with the strength properties of Eutectic Super 146 XFC and modern methodologies of brazing work.
Back in the day, we only had brass rods and messy paste flux.
Nice work sir,
The silicone brass filler he uses is stronger than the cast by a long shot. The cast will break before the repair. Silicone bronze is tough stuff!!
@@paulcopeland9035I second this. They are keyboard beating instead of knowledge of Metallurgy.
Years ago a brazed a carburetor for a John Deere D back together. A co-worker pulled it out of his garage with the door not open all the way.
its an art
I love the videos where you help out hobbyists. I can imagine myself in the same boat.
Veeing the crack out..one of my favourite pastimes.
You and Keith Rucker are both in agreement that bronze brazing is the best way to repair cast iron.
AND Keith Fenner !
Have you seen Bob Moffits (Let’s Weld Something) video repairing cast iron with cast iron, it’s welding casting with 1/4” cast iron rod and torch.
Adam is looking like a pole dancer with all the glitter on him😂😂
sentiments - i miss my Dad, what I wouldn't give to be working next to him again. I can almost see the same choke that I feel when I try to explain the "Dad was awesome"! thing to my daughter, and she'll never understand (until I'm off at least)
Another great way to preheat parts like this is 450 for 1 hr in a oven a electric oven in a shop is actually pretty useful heating bearings before pressing preheating stuff even powder coating
Make an interesting experiment to do some brazing repairs on the same materials and see what the difference in strength between a full depth braze when ground off flush, or left proud. Certainly have heard other you tubers say a braze is as strong as the original... but they all leave them proud!
its never going tolook as good as it did before it was broken no matter how good at brazing you are . its a nice jobof brazing this soi ts at least looking ok and usable
i have stick welding rods specificaly for cast iron. after a good preheat a would tack the parts with them and then braze with phosphorbronze. this way there is no risk of brazing through. although the stickwelding with the dedicated rods should be okay i found that you never can trust cast iron so brazing is the way to go.
Not sure if cute or not, but someone even I could have a drink with. Preferrably while teaching me to bbq 😂
Truly an amazing repair. The level of detail and skill provided by Abom is truly incredible - and inspiring. Thank you.
I miss having a torch in my garage for this type of repair
Looks good Adam, it's nothing a little JB weld or body filler and paint can't fix. Abby has been killing it with the cinematography lately, getting some great shots! 👍👍
I have always relied on capillary action to draw the braze material into the joint. Personally I would never have gouged out so much material. You can also use an aluminum form like a tinkers dam to stop the braze from falling out of the joint.
Did the Keith Rucker on that.
I saw that… small parts are a PITA.. nice job! The only other choice would be a recast…
Great job…best possible repair!!
With cast iron... other than machining a WHOLE new piece. Brazing is the strongest option.
@@PaulRyan-po9xc What other options do you see?
I wonder why the pawl doesn't have a spring. Maybe gravity? Does the needle scaler also help in stress relief?
That’s a perfectly great raising job and perform there. It would be nice to see these two parts, finally installed on the drill and to see them in action.
really good brazing video, Abom. it felt like i was doing it myself...although your work is so much better. Great camera work and beautiful repair job. Thank you!
I feel his agony on temperature - time - flux - welder - and mechanical strength. it's not different from electronics soldering. most problems came from oxidation.
