thanks folks....good call on grinding down the cheap wrenches. i was hoping to find a set, but i needed the 9/16 first. thanks for the brainpower! Sent from my SM-G920P using Tapatalk

Hi all, I figured you experts would know the answer to this one, pretty easily. Does anyone know what manufacturer/model makes box wrenches with the smallest outside radius on the "box"? I've attached a photo, since the terms are a little vague. Basically, the wrench pictured is 9/16". The...

does anyone know when wilton started using ductile iron in their combo and machinist vises? Sent from my SM-G920P using Tapatalk

sorry folks. i didn't mean to stir the pot too badly. Sent from my SM-G920P using Tapatalk

IMHO the best "bondo" for surfaces in cast iron is ER70S6 applied with a mig. Do not use TIG - you're not going to be able to add enough metal into the puddle fast enough to prevent weld puddle cracking. As for non-structural filler, any two-part epoxy based product works best in shallow pits...

Sorry. It's dead wrong. It's totally dead wrong. If you read the post, it says that they are all made of 60,000psi ductile cast iron. I'm not the smartest guy around, but I know wrong when I read it. The worst part is if some new guy reads this post and starts buying old machinists vises for...

I just want to note that the original post says: "The machinist's vise is considered the "cream of the crop". They are stoutly made and are finely machined. The jaws should match up perfectly, and they will be made of very high grade (60,000psi or greater) cast* iron." This is pretty much...

You could salvage it for parts, but I wouldn't pay much for it. On second thought...No replaceable jaws, missing pipe jaws, missing swivel base. It probably isn't even worth scrap, unless you're a scrap dealer. Don't buy it! If it had replaceable jaws and the swivel base, it might be worth...

The real question is who is your local scrapyard selling to, and for how much? You're really asking an economics question. If you're planning on producing a product, you really are asking who your market is. No, I have no idea :)

Sorry - you're absolutely right that A36 is the norm for structural steel. Great when making things that need strength from being in tension! I guess "terrible" is too strong a term. I guess what I really should say is that its mechanical properties are not as good as other steel alloys, but it...

So what were Wilton Combination vises from the 80's made of? Or are you just saying that it was used in the vise industry, just not commonly?

You're correct for sure. Ductile Iron is a "modern" material. Any vise made before 1943 is most definitely not ductile iron, correct? And even after that, it probably took the better part of a decade to achieve commercialization and later than that to achieve widespread adoption. Before...

First, please disabuse yourself of any notion that country or origin or cost has anything to do with the quality of a vise. There's only a weak correlation - no guarantee. Second, understand that metallurgy and metallurgical science improves over time. It does not go backwards. For some reason...

That was the easy part. Now planning the surgery. The plan is to drill the ends of the cracks with 1/4" holes. Then grind out the neck on the top to accept the repair using a die grinder. The plan is NOT to grind the crack at the main body casting, but grind into the neck instead. If the neck...

One thing I like about the 571 is that the vise itself is beefy for a 3 inch machinist vise. The slide is very thick, the jaws are cast solid. With the parts put together, I'm inspired to continue.

Blasted the vise. Using the torch, anvil, and a small sledge, straighten the base lockdown handle. It's not perfectly straight, but straight enough. After a few years of use, I'll probably cut the original rod and replace it with heat treated 440c and some quick turned balls on the lathe.

crguy: I understand. First of all, I'm not a tool collector. I don't sit there and chew my nails wondering what my vise is worth. I'm not talking about putting hundreds of dollars into fixing this thing. It's $20 of nickel welding rod. I have a workshop. Second of all, I think this vise is...

Thanks all, I really appreciate your advice. Carla - given that you have a great deal of expertise of the subject, what brazing rod in specific do you recommend for this application? Assume that I am using proper heat application and fluxing. I'm assuming that the state of the art in brazing...

with deepest respect, are you 100% sure? The vises that Rock Island made for Craftsman were all semisteel. It seems terribly unlikely that Rock Island would make their own vises out of a different material. Also, this is novel information on the composition of Rock Island vises with not a...

Thanks for the responses. I'm new, thanks Carla for your priceless ad-vise. but... You know how some people ask, "explain it to me like I'm five?" I usually ask, "explain it to me like I'm a materials scientist." :bounce: I would have hoped that someone would have insisted that I start with...
