Want to Make Adjustment Screw 18" Crescent

Where's the fun in that? :)

I have to agree with pstemari. It's great to have a machine or two and be able to make a part or fix
something that someone else gave up on. Of course there is a point where it is more practical
to buy a ready made part. For me, its the challenge of using a machine to produce something
useful and cost effective at the same time.

That's why I started machining.
A) to fix things that parts were no longer available for,
B) to fix parts that were just too expensive to replace.
C) for the fun of things
D) because I was already called McGyver by many of my friends. And have always been solving problems..
E) Fill in the blank __________________________________________
F) All of the above.
 
Make it if you can't buy it
If you can buy it don't make it
That is most likely a forged high chromium
Alloy steel heat treated and tempered
You should use 4140 HT steel 29 - 30 RC
If you make it

Most hand tools like Crescent and J H Williams are made from AISI 6145/6150 steel. Not saying that it's 100% correct but close.

Looks to be a modified buttress thread .. with about 6 or 8 threads to the inch. Just guessing....
