Re: Thin workholding suggestions

One thing to keep in mind is that flat material has a tendency to bow when you remove stock from either side. If you hope to keep the parts flat, it's a good idea to remove material in steps, alternating shallow cuts and flipping the part, so a roughly equal amount of stock is removed from both side...

Over engineering may not create a better widget. The point one should take away from this discussion is that c...

Re: Two Silver Soldering Questions

Correct. It's not a tolerance issue, it's an engineering issue. Tight tolerance, in and of itself, won't be cause for an assembly to not function . In fact, it is instrumental in achieving consistency. If a fit is improperly designed, widening the tolerance exacerbates the problem, while tightening ...

Re: Keyways

If a 1/4" straight keyseat was cut for a length of 8" on a 1-3/16" shaft what are the odds this might affect the shaft straightness? Pretty much 100%. It's just a matter of how much. Any time you remove metal unevenly, you can expect movement. That's especially true if you interrupt cold finished m...

Re: Building the 2.5" Scale Shay

I also need to figure out how to attach the cast iron smoke stack ring to the steel pipe for the stack. Maybe careful brazing? If the ring has enough wall and thickness, and you'd like a nice, clean look that can be disassembled, you might consider drilling and tapping the ring, and using fasteners...

Re: Keyways

If the proper Woodruff cutter is used, the key shouldn't present any problems, as it should be a snug press fit in the slot. They offer a real advantage for some situations, as the key doesn't present any problems by moving or dropping out. If you choose to cut your keyways with an end mill, do keep...

Re: Treatment to Toughen up MDF Table Top?

Speaking of butcher block, a section of bowling alley would make a great table top. I'd like to have an 8' length for a loading bench.

Re: Things they dont tell ya when you start casting. :)

While I have a keen interest in foundry work, my casting experiences have been limited to pouring precious metals (primarily silver and gold). That said, the reason I made mention of precious metals is that if there's one thing I learned from refining, it's that molten metals are fierce solvents of ...

Re: Treatment to Toughen up MDF Table Top?

I use a 1/4” thick Masonite on top that I liberally coat with boiled linseed oil. That’s been my choice of replaceable workbench surfaces since the ‘70s. Cheap, durable and non glare. Just be careful with any rags soaked in the linseed oil. They spontaneously combust. I, too, use Masonite for my ta...

OK then why not start a new thread on the live steam forum so others can comment. I do agree with you but the guy was just selling pump I'm glad he sold them all. There are a lot of work for little money. A new thread might have been nice, but the questions or comments were posted in this one, so t...
