All milled out and ready for screw holes.
I have a few pieces cut out but that is where I am at with this project.
Thanks for looking!
I have a need to punch some louvers in an upcoming project. These things are pretty spendy. 500 to 800 dollars for a decent one. I did the same thing here as I did with the Tubing Straightener. Designed it in 3DCAD and am building it in the shop.
Here are some snapshots off my computer. The blue pieces are the punch and the white pieces are the die.
The back. You can see the actual punch in this pic.
This pic shows the stripper plate in place. This plate contacts the sheet metal before the punch does. The die springs will help hold the sheet in place as the punch starts to work and also keep the metal from distorting to much.
I have gotten started on the build. The punch die is milled out and has holes laid out for drilling and tapping as well as the lower support plate that carries the punch die and shear plate.
The punch die.
Continued in next post.

Got out in the shop for few hours today. i got the lower support plate drilled and c'bored and the punch die drilled and tapped. Surprisingly the two pieces bolted together so i must have done something right...
Drilling the base plate with guide holes. There are six of these that will be drilled out to .343 and then c'bored for a 5/16 SHCS
One more to drill and it's ready for c'boring.
At least all of the screws fit...
