Subject: Scotchman 314 Ironworker


Iowa		I know nothing about these and would appreciate any information on them.

I see some on ebay/facebook/craigslist for up to 5000 and then I see auction results around 1000 so what would you guys say is a fair price for a decent one you could bring home and put to work?

Are there any certain things I should inspect if I go look at one?

Are parts (if it needs any) readily available?

Thanks.

Iowa		Will do. Figured if I get one bought I will most likely need to get ahold of them and get a owners manual/parts book. Thanks.

Franklinton, LA		There are 3 things I always keep in mind when punching holes in steel.

First, the die should be bigger than the punch by 1.10 - 1.15 times the thickness of the steel. For example, if you are punching holes in 3/8" thick steel the die should be 0.038 - 0.056" larger than the punch. If the die is too large the hole will be cone shaped and not very smooth. The punch life will be reduced and it could break if the die is smaller.

Second, when punching mild steel, it will take about 30 tons per square inch to shear the metal. For example, it will take about (3.14 X 9/16" X 3/8" X 30 tons/square inch) or 19.9 tons to punch a 9/16" hole in 3/8" steel. You can punch holes in medium carbon steel but it will take more tons. You will hear a loud popping sound and the press will jump when punching the hole. Also, the punch and die life will be reduced.

Third, the punch dia. should exceed the thickness of the steel. Calculate the force per square inch on the punch to see why.

For more information, you can buy an older edition of "Machinery's Handbook" on EBay for a very reasonable price.

Iowa		That's good info.

I've had my southbend for a few years and got a bridgeport in January so yes I need to buy a copy of the "machinery's handbook" for sure. Thanks.

Franklinton, LA		I appreciate your comments.

There are several little things that I did not mention. For example, a die 1/32" larger than the punch works good on 3/16 and 1/4" steel. A die 1/32 or 1/16" larger than the punch would be ideal for 3/8" material and a die 1/16" over the punch size is ideal for 1/2" steel.

If you heat the material, the force required to punch holes will be greatly reduced. The material should be warm but it does not need to be heated to a cherry red. You need to let the punch and die cool after punching 4 or 5 holes. Also, you will not need as much clearance between the punch and die so the holes will be more cylindrical. Finally, if the material has been heated you can punch holes that are smaller than the material thickness. For example, they punch 9/16" holes in 1 1/4" thick chisel plow shanks while they are hot.

I did not mention you really need a good sturdy stripper. I don't remember how much force it takes to strip the punch out of the material. Machinery's Handbook should have information on this. If you don't have a good sturdy stripper you will have problems and you will waste a lot of time.

I hope you enjoy using your new shop equipment. I feel certain everyone would enjoy photos of your shop projects.
