Re: Another "How to make" question

Your image is much too small to be read. Yep! Pretty much useless. When posting pictures, don't make them thumbnails. The software does that automatically. If it's important that they are legible, post them an appropriate size. The software shows a thumbnail, but it can be clicked so readers can se...

Re: Atlas quick wheel

I think you'll find that sockets aren't too hard to machine. If they were, they'd fracture under shock loads, or under excessive stress. They're tough (likely near 50Rc), but machinable.

Re: Micro torch?

Be aware that the torch set does NOT include regulators. It's a knock-off of the Smith mini torch, which comes with not only regulators, but a set of mini bottles. The torch set offered would not be functional without them. You need not worry about the smallest tip if you acquire a Smith torch, as o...

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...

Re: Two Silver Soldering Questions

Harold writes: Tight tolerance, in and of itself, won't be cause for an assembly to not function. But it may be cause for it to not be manufactured. And that, too, is an engineering issue. 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...
