Update 2: Circles and Boxes

Post date: Sep 17, 2014 1:45:36 AM

Had a rare chance to work in the shop this past weekend.

A couple weeks ago I bought an adjustable circle-cutter from Harbor Freight. It was pretty fiddly to set the proper diameter(s) on it, but it was cheap. It isn't fit for precision work, but for costuming purposes it was more than sufficient. So I recut the circles on the upper arm of the Synchronous Generator and also cut the four rings on the Cyclotron:

These circles turned out much better than the ones I originally cut by hand.

I'm waiting to glue it all up until I can properly size the N-filter.

I also took a 3/8" round-over bit and rounded the edge of the Cyclotron with my router.

Next I roughed out the EDA and Booster:

Both pieces are basically boxes built out of 3/4" thick scrap wood/MDF. It went quick on this end, but there is a lot of filling and sanding in my future....
