Re: New machined Stephenson links from Allen Models

No question what they are a good product. Wire cutting hardened tool steel gives surfaces and dimensions virtually unheard of 35 years ago without hours in a Moore Jig Grinder. I put AF NYLON bearings in mine 20 years ago (have a MITS WEDM MACHINE) and forget about them other than to splash some oil...

Re: New machined Stephenson links from Allen Models

no....is not a problem.

been making these links with wire for years with a .008" radius in the corner and they never break.

a SHARP corner is another matter, but .008, as small as it seems, is above that threshold

Re: New machined Stephenson links from Allen Models

the jamming is because of radius interference caused by the diameter of the cutter.

when you are cutting with wire at 0.008" diameter, the radius can be very small.

you are correct - doesn't hurt anything but looks a little strange for a wire part.

Re: New machined Stephenson links from Allen Models

Re: Attaching the smokebox

I use flat head socket head cap screws, countersink and cover them with the boiler cladding. Nobody will know they are there. Dope in never-seize 4 or 6 screws are more than enough. I cannot tell you how much work it was to get out 72 screws on a boiler that I rebuilt for a friend. They had been in ...

Locomotive Efficiency is measured in terms of smiles / miles

Re: Have G-code. Can someone run these?

ACTUALLY I am not...but being in a position where I support people who run machines for a living and do estimates, I know exactly how they will think...and time is $$$ and setup is time. I have a few customers that I can contact to see if they are interested, but I need a DRAWING, not code. From a m...
