Make your own die cut meter diffusers

I'll do anything to avoid cutting out meter diffusers by hand. This project solved that problem.

You can make your own die cut meter diffusers. It just takes a steel die, and a die press. The die is ordered from China. The die press can be purchased used. Total cost about $80. Or use your bench vise as a press and save $40.

I found die makers on a web site that craftspeople use to buy and sell. All the die maker needs is a drawing of what you want. I used this drawing to order a die for the small meters found on the majority of Marantz 22xx and the 2325 models:

Here's the resulting die, and the modified die press:

The die and the diffusers:

It's so much fun to make them that I have a lifetime supply already:

The Sizzex die press is widely available used. It has to be modified to work with the die I purchased. Spacers were inserted to increase the die height that will fit in the press:

It will cut through 6 layers of 48# vellum and returns 12 diffusers per letter size page:

This old post, I just found. What a cool thing to have. I love it. But for me I’m about to try surgical scalpel.

"Lifetime supply". Heh. Not quite. Thousands of LED kits with these die cut meter diffusers were shipped out during the years following this post. The kits included the correct dial diffuser too. Now I just make diffusers for my own work.

The folded over (doubled) #48 was difficult enough.
But prying and crying getting the bottom meter box tabs back in place was the hardest.

I missed this thread the first time around. Where I used to work, these type dies were used to cut out our "laminates" basically a sticker used to label the fronts of our products. There were always registration issues as these had lettering and graphics. Finally my boss got a laser machine and also some good professional printers and we made our own. I did the laser cutting file programming on the first one or two, then handed it off.

Our friend @tonebells used his wife's Cricut craft cutter machine to make some black paper meter surrounds for Marantz signal meters and gave me a stack of them. Lifesavers! I owe ya one Tony!
