Greetings All
I'm working on building a forge and have run into a problem. I was given a hand crank blower I've mostly got rebuilt and working. The problem is some of the screws are odd. I'm trying to find the following
When I give the sizes to hardware stores and machine shops they respond with "What was that?" or "You don't have that."
Any help???????????????
Thanks
1/2-12 was pretty common before UN threads were introduced. I've single-pointed a few 1/2-12 cap screws when working on old woodworking machinery.
I've never run across 1/4-18, but one quick fix would be to open up those holes to 5/16-18, assuming you've got enough material to do so.

If you need a screw or bolt made anyone with a screw cutting lathe and a Machinery's Handbook can make what you need. Alternatively you can drill out the tapped holes and re-tap to modern standards as previously suggested. What ever is easier is best.
