I wasn't completely satisfied with the circular piece of Lexan I had cut out last time. The inner hole was sloppy and I knew I could do better.
Once again, a trip to my local Lowe's. This time I bought a PVC/Metal hole cutter, which has a much less aggressive cutting tooth than a regular hole cutter has. The inner diameter is 1 inch and at a cost of $7, it was one of my cheaper trips to Lowe's in quite sometime.
After making another 3 inch circle in Lexan using the Dremel, I clamped the piece into the drill press and using the circle cutter. Since the circle cutter has a drill bit in the middle, it lines up on the center hole used to cut the circle, making the job quite easy.
It took me a long time to decide what I wanted to mount the lexan piece onto. Another piece of plexi? A thick piece of aluminum? I opted for aluminum since I had a small scrap piece I think will do the job.
Going very slowly and with a generous amount of WD-40 to lubricate the hole cutter, I drilled a perfect 1 inch hole into the aluminum.
Here's what I have...
|Electrical Slip Ring, Aluminum mount and Lexan Softpot mount|
As you can see, the slip ring will fit with a bit of room to spare. Excellent.
Next up is trimming the aluminum piece a pit, mounting the lexan onto it, then the block onto the frame. Once that is in, we can fine tune the installation of the stylus.
