How To Make A Hand-Operated Holepunch

So as mentioned before I will be uploading a few more "Workshop Equipment" series titles, published by Intermediate Technology Publications.

Today you can download "# 7 How To Make A Hand-Operated Holepunch". As I mentioned before I have taken a bit of time to assemble this file, and you will not find a cleaner version of this title on the internet.

I would consider this project one of the more advanced in the 10 volume series. If you have not done a lot of metalworking before, it is important to go slow and verify your work continually before welding up your assemblies. The finished hole punch will be a great time saver for anyone who requires a lot of holes in sheet metal. It will punch holes up to 25mm or 31/32" in 16 guage  material.

Probably the hardest part of the project will be, making up accurate punch dies. Above 9/32 to 31/32, lacking a suitable supplier, you will have to make your own. Instructions are in the manual.

For holes 9/32 or smaller a cheap alternative is to adapt the punch dies from a hand hole punch, done easily enough.This inexpensive set cost only $34, 10 years ago. It works, but it is a slow process. Installing the dies in your new holepunch would greatly speed things up.


So If you would like to download this nice plan manual, go to my Books - Free Downloads page. # 64 - 4.4 MB - pdf.
