Thread: home made dome washer

This is the result........

In the future I will try to find some threaded rod so I can tighten up on the collars to prevent the free wheeling.

Here is a pic of the collars w/set screws...

Perhaps another way to turn down the diameter of the washers would be to put them on a 256 bolt, cinch them down with a nut, mount it into a drill chuck and use a file or sandpaper.

Here is a link to all the pics...

Have it run in slide show mode for better closeups.

I hope this gives some good ideas.

Here are some of my pictures, very similar to randy.






I use the following punch dies - 5/32" for the initial punch = "washer" & the 1/16" to punch the center hole.

There is very little burring on the edges, the more your punch cuts the more likely you will get burrs. Because of the nipple on the intial punch, you find yourself with a near perfectly centered divot to guide the 1/16" punch.

These small washers finish with a slight dome to it already, but if I want traditional looking domed washers I use a larger punch (larger washer) and use the daping block.








Just to show how it looks on scales that I am working on (not pinned of course):

And if anybody is wondering what type of metal to use with one of these tools - anything 16 gauge and thinner.

I used a steel casing from a crappy old pocket knife. Its scrap, but its good hard steel and it works - why waste?

Count the holes...how many razors can I repin with just the one side? This knife was worthless before - worth a lot more now.

Was going to go look at one of those today,but got to busy.
Looking at the above pics It looks to me that it would be very simple to machine the 1/16 hole punch mandril so that you can punch the center hole and dome the washer all at once,will ck it out.

Tim, what thickness of metal did you use?

I agree. I have been searching for different dies and punches, but no luck. I would be interested in buying a custom punch for the this tool, especially if its punchin out complete domed washers!

Thanks for posting this.
I went to my shop and dug out my old Whitney Punch.
This is a great idea and simple to do.
Look on ebay for a used Roper Whitney Punch No.5 Jr.
