Definitely an inspiration to get out in the shop! Not sure if you get any time to read these comments, but one word of advice - clean your MIG gun nozzle. All that spatter on the end will disrupt the gas flow giving you a less than optimal shielding gas envelope and can lead to porosity and a weak weld.
@silasmarner75862 жыл бұрын
I agree. That nozzle is a horor show. YOu are correct !
@ricko51232 жыл бұрын
Always keep it clean, agreed. A nice new tip and a nice clean nozzle is like the difference between a dull end mill and sharp end mill. A little gel dip helps as well....Ricko

I've done this kind of repair a number of times and find the concentricity to be much better when the stub is a press fit into the hole. Good job!
@pauldorman2 жыл бұрын
I wondered about this, but could a tight fit introduce additional stresses once welded (given the dissimilar steel alloys)? Speaking of stresses, would it be overkill to temper the weld with a torch before final machining? Without knowing what MIG wire Keith was using I don't know if the welded area could have become brittle and susceptible to breakage if accidentally knocked sometime in the future. Heat might also reduce the run-out perhaps, but then again I suspect you could easily end up chasing warps all over the place and ruin the leadscrew.

@@pauldorman I would think annealing the weld would be a good idea taking care to limit heat to the weld area only.

I was wondering why he didn't cut that for a press fit, for that reason in addition to not having to hold it. Or even go farther along those lines, bore the hole bigger and shrink it onto the new stub, could probably get away with no weld even.

Good workman job. I have stubbed a lot of shafts, would have bored that hole a bit if I could, turned part to shrink fit in or at least a hammer fit. Just makes the welding easier, as far as the welding goes, I am an old 7018 guy, but your wirefeed weld looked good. Trued up center, great. Vibration, I have had to drop rpm down into the dirt at times, high speed tools work. Threading this is easy, any multiple of the leadscrew pitch, just engage the halfnut. Probably 4 tpi, so 4, 8, 12, 16, 20, 24 etc, just engage the halfnut, don't have to look at dial. Got into a job one time, 5 tpi, running on steady, extension bar to hold toolbit, carriage past point I could use chasing dial. Chalked the chuck and watched keyway in leadscrew. Got it done.

I saw something like this over on the Cutting Edge Engineering channel. To get the weld straight he put the part back in the machine and held the piece to weld on with the center of the tailstock, then tacked it in place, then finished welding on a welding rotator. Would have been nice if it would have gotten welded on straighter, but if it still works as intended there's no problem.

How I do this kind of repair is to make the register a slight interfierance fit, heat the shaft and freeze the slug and then tap the slug in and allow everything to normalise that way you can set the shaft on a pair of V blocks and true it up with a dial indicator. Then tack it up at 180 degrees to each weld at four points and check with the indicator again, if its out tack the high spot and then quench. Then to fully weld I preheat the whole thing and have the torch mounted to the bench with a clamp
