Re: Shaper forum??

I have a 12" Gould & Eberhardt that is old enough to have poured in-place babbit bearings. I put a new gear rim on the bull gear many years ago. One of those tools that is nice to have but rarely used. I have been offered 24-36" shapers just for hauling them away as shops needed the space for modern...

Re: Narrow gage wheel sets

Not the kind of grinding you were thinking of; they do posses a tool post grinder, but the stone on it might have been chipped out of a medium cobblestone. The shop supt started there at age 17 and just celebrated his 50th anniversary in the shop. Shop probably was set up in the mid 50s as the local...

Narrow gage wheel sets

A local shop is currently making some wheel sets for the Cumbres and Toltec; four sets with 3 3/4" journals and Muley ends, and four sets with 4 1/4" journals and conventional ends. The wheel chuck in the four jaw is 26" nominal. Wheels are new steel and the axles are 4140 annealed. The wheels are f...

Re: Pinched rod ??

Most likely it was made with a hardened steel die in a press. You could make something similar that could be used in a vise - two jaws of a hardenable steel with the correct profile - some sort of alignment pins or frame, and insert rod and squeeze.

Re: RE: JET JVM-626

I found a riser block essential - always trying to get a big part into too short a space. My riser is 12" long and 16" dia - on a Gorton 1-22. For small parts I have a rectangular block that goes under the vise, and I have a riser block for me too!

Re: RE: JET JVM-626

When we made risers for a mill, we added a number of reinforcing ribs inside the riser, not uniformly spaced. Made it a lot stiffer and not subject to any one frequency.

Re: Milling slots in 1045

1045 is a hardenable steel, we use it for mild duty springs and lock nuts at the RR. It may work harden. FYI

Re: Anyone certified lately

Might add; Probably an AWS test (American Welding Society). Some tests give you a lot of range in what you can weld afterwards and some do not. If you have a choice, take one that gives you a wider range before you have to take another test. Usually a difficult position will cover easier ones so ove...

Re: Anyone certified lately

There are many many different certifications, so ASAP, determine which one you are doing - that should dictate the rod type, metal thickness, position and the other variables. Get a copy of the structural code if possible - it should list the tests. Each industry has multiple certifications and most...

Re: What is it???

I have seen something similar that was used to set exact lengths on connection rods. Possibly to set up linkages.
