I need some help

[Hpozzuoli]

I am hoping someone with a cnc or water jet might be able to help me. I need to make 18 of these aluminum shims for a vending machine I am rehabbing for my laundromat. Currently I have enough shims to accept $.50 , but I want them to be $1.00. The company is out of business and I haven't found anything comparable. Phoenix Specialty is my last resort, but I think they might be pricey.

I was thinking my bandsaw, but I don't think I can get it good enough free hand, especially 18 of them. I would take care of anyone willing to help.

Here's what I need.

I am going to keep this current today if someone can help me out.

I can laser cut them depending on the material thickness. i assume they are around 1/8" thick looking at the pic. Contact me. They are not going to be "cheap" because of the design / drafting time to get set up and cut. the actual part will not be much.

Thanks

Dan-Here's the measurement. PM has been sent. Thank you.

 

[Hpozzuoli]

Just checking to see if anyone else has some options for making these

Not knowing how they work, but instead of making a bunch of individual shims can you make one solid piece the equivalent thickness of the number you need? Or are they not stacked on top of one another in use? What is the outside diameter?

 

[Hpozzuoli]

I can get that info tomorrow with some better pics. They are stacked in succession, but between each aluminum coin disc is a black plastic shim to keep the coin slots separated. I have enough to make all the products $.50, but would prefer to make everything $1.00 to justify installing this thing and make it generate some revenue. I am recessing it in a wall so you only see the front.

What about a hole saw and a drill press if you can clamp them down. Or a step bit

 

[Hpozzuoli]

Here's the better pics. I appreciate all the pm's.

 

[Hpozzuoli]

Here's another. The aluminum coin disk is spaced by the black shims. The more coin discs the more money for the product.

Last one.

Here's the vending machine.

we used to make these In the lathe. cut a stack of plates about the right size and make a jig to drill the two holes and the gap (use a unibit maybe for the coin capture hole) fasten them in a stack with two screws with a bit of alloy bar to align them all. set them up between centres and machine the outside. we used to have a jig someone made, back when we were rebuilding parking meters for a living. it was an alloy bar with a flange at the back and a centre hole and a drive arm screwed or welded on, and a cover cap with another centre. as long as u were careful, they usually all worked. hope this helps. but back when we were making a lot of these in the repair shop (not all that long ago) we didn't have cnc.

don't know how well I explained that. the drilling jig was a piece of hard die steel with the three holes in. just drilled them by hand and dropped little pins in the two holes as u go. the big one was drilled with a trepanning bit like one of those portable drill units u see now, hollow. a unibit would probably work well, or even a woodwork spade bit maybe. not sure. when u have all the plates, (we used to make about 10 at once unless it was quiet, then it was an apprentice job) clean them up with a file so theyre flat and slide them on the jig and screw them all up tight. spin it between two centres and machine it all down till its the right dia.

If you can send me a sample, I can help you out. Send me a PM with some particulars about it, and we'll talk. Or PM me your phone number and I'll call you on my dime.

Personally I think you could do it with the proper hole saw, unibit, and layout?

1) Drill the unibit hole for the quarter first

2) Plan layout of hole saw based off the unibit hole

Oh and a sander to sand down to proper fitment. Good luck.

How about knock out dies? Knock out the hole for the coin first and then the shim. Drill the two holes. Knock out die will go through aluminum with ease. Reason I would do the coin hole first is to help avoid bending. May need to pound flat anyways if it bends.
