Hello,

I have a side business with a few products. My day job is getting busier and I just don't have as much time for machining as I used to. I have a couple product that will need parts soon. Most of my parts are aimed at the High Power rocketry hobby. They are all 2.5D. I've been making them on a CNC converted Grizzly benchtop mill using Fusion360 for design and CAM.

Here's the first piece. It's a small Delrin screw switch cover. They are .875" L x .4" L x .4" T. I start with a 6" x 16" sheet of .500 thick Delrin clamped to the table. I cut 9 x 11 parts per sheet. I cut those sheets into 9x1 strips on my bandsaw and do the back side in a soft jaw.

Front side operations.
1. Drill .125" holes .425" deep.
2. Drill .1875" holes .4" deep.
3. Drill .1875" pockets .125" deep.
4. Drill .375" 60 degree chamfer .325" deep. I use a sharp pointed 60 degree countersink.
5. Outside profile.

Back side operations.
1. Drill .3125 pockets .225" deep
2. Face off .100"

The tolerances are pretty loose +/-.005" would be fine. I just use standard drills and don't measure the hole sizes. I cut the chamfer as deep as possible without chipping the edge. You can make it .360" OD if that helps.

I'm looking for 500, 750 or 1000 pieces.



Thanks,


Chris
