Dreaded crack sound
|
I'm betting it would be a LOT cheaper to make your own from some mild steel. Don't see one on ebay right now, but there's a photo of the clamp plate in this complete tailstock:??https://www.ebay.com/itm/156345978749? You don't have to copy it exactly, either.? A flat plate with a bit of? all thread located in? should let you use your tailstock.? If you're a collector rather than a machine tool user, it would at least let you display the thing while you search for the right parts.? Might also ask Clausing if they have the part? If not they'll often release the drawing. There are several threads here that give contact info for them.? Bill in OKC? William R. Meyers, MSgt, USAF(Ret.) Aphorisms to live by: Good judgement comes from experience. Experience comes from bad judgement.? SEMPER GUMBY! Physics doesn't care about your schedule. The only reason I know anything is because I've done it wrong enough times to START to know better. Expect in one hand, expectorate in the other. See which one gets full first.

Also, cast iron is not too difficult to braze. If it's not in too many parts. Forney makes a nickle-based brazing rod if you want a slightly better color match, and brass brazing rod will work. Properly done brazed joints are not quite as strong as the base metal, but should work.? Can also be welded with special weld rod for cast iron. That's supposed to be more difficult, but also stronger if done correctly.? I've done a bunch of brass brazing over the years (for a hobbyist) and clean surfaces, a good flux and enough heat are keys to getting it right.? Bill in OKC? William R. Meyers, MSgt, USAF(Ret.)

For future reference you can build an "oven" from firebrick to concentrate the heat from multiple torches. It's not impossible to find propane or acetylene torches that are airbreathers, like the Prestolyte and TurboTorches. Oxy-fuel torches for both gases are available, too. Initial cost can be high if you buy new, but you'd be surprised at all the things you can do and fix once you've bitten that bullet.? I'm not a professional welder. More a "farm" welder, but I was taught by a very accomplished all-purpose welder. Just need more workspace, practice, and materials... Hi! My name is Bill, and I'm a toolahaulic!? Bill in OKC?

Youngest is a professional welder - he said it would be a PITA as small as it is.
I also don't have anything that generates enough heat to braze. I figured if I couldn't find one I'd call Clausing. Luckily, I went down to Shapiro's the other day https://www.shapirosupply.com/ and found some nice scrap 1x2 either hot rolled or forged bar stock. It's heavy as heck. ;) Milling one from ruler measurements wouldn't be difficult. That way I can get it back to a point that allows me to use the tailstock.

All there is for what? If you have the tools, you can build better and more complex tools. If you have the skills. The guys who started all this had files and hammers and chisels and saws. Now there are machines that can machine an entire engine block... and before that people learned to do quite a bit on their own.? And there are books, magazines, and videos. That has not always been so. I've 3D printed gears that fit my Atlas lathe. I've made backplates, collet holders, way bars, milling tables, and parts for industrial machines to keep them running. Melted and cast parts in metal, and machined, forged, ground and filed bits and pieces to make and repair stuff. Worked as a mechanic, assembler, or technician on high performance fighter jets, racing go-karts, micro and main computers (missed the mini-computers), AV & photographic equipment, satellite and radio communications systems, home & industrial appliances and other machinery, and automobiles, boats, and bikes,? both pedal & motorized.? Ebay is far from the only source, though it can be a good one.? Bill in OKC? William R. Meyers, MSgt, USAF(Ret.) Aphorisms to live by: Good judgement comes from experience.
