machinest, metalworkers, fabricators, need help finding product ..
I'm hoping someone out there can help. I am repairing my KR Wilson pan jig. It has 10 locating pins that are 5/16 diameter on one end and 3/8 diameter on the other end They are about 1 inch long. Does anyone make a step-pin or something that has those 2 different diameters. I can machine them myself, but if there is something that is already machined to those 2 different diameters, that will save me a lot of work ... My old equipment will require me to make them one at a time. I do not even know the term to use in searching for something like that. All I can think of is step-pin or step-dowel . ??? Any help will be appreciated.

Re: machinest, metalworkers, fabricators, need help finding product ..
I Googled "stepped dowel pins"...
https://us.misumi-ec.com/vona2/detail/110300256840/
I found a stepped threaded stud, years ago in the bolt cabinet at a VW dealership I worked at.
The threads were gone in the aluminum head on the rear of my H-D, where the exhaust pipe bolted on. Was an Allen head bolt, 5/16", I found 8mm/10mm stepped studs and rethreaded the head for it and used a lock nut. Still in there 20 years and 60,000 miles later.

Re: machinest, metalworkers, fabricators, need help finding product ..
I may have not been clear on what I'm needing. I do not need a threaded stud. I need both ends to be smooth. The term may be "step dowel pin". Here is a diagram of what I need. If I could find a machine shop with CNC to make them at a somewhat reasonable price I would got that way...

The link I posted was for the pin in your drawing. It's not threaded.

Re: machinest, metalworkers, fabricators, need help finding product ..
The Mcmaster Carr part and my part I need are "about" 1/2 a thou. (.0005) different. The less than a thou bigger on the 5/16 end is to allow the pin to be driven into place and not fall out. As to the 3/8 end being about 1/2 to 3/4 thou different. I do not think Ill ever be able to "beat into submission, with a BFH." a model T pan anywhere near close enough to worry about a 1/2 a thou.... Straightening a model T pan is a somewhat violent affair.
This is one of the reasons why the forum is so usefull. The wealth of knowledge and contacts to get things, or get things done is amazing. I could not have machined these myself to the tolerance the "store bought parts" have. I can work to .001 pretty easily with my antique/ancient machine shop tools, but a 1/2 a thou is a struggle ... Not to mention the time saved. I bought enough to fix my KR Wilson pan jig and also got a few extra for about 41.00 delivered to my door. Im as frugal as anyone, but sometimes it is best to "choose my battles" Thanks again for all the input ...
