This is a project that I've been sitting on for quite a long time. In fact, the nozzle is one of the fist purchases I made on the rpf way back when the rpf was relatively new. I was hoping that more parts would become available, but as far as I can tell, it never happened.
The base of the phaser came from an R2Builder back when that club was just starting to form. The control knob came from a local surplus store. I came across that one a few years ago and I'm still surprised that it's correct. I took a chance purchasing it because I wasn't sure of the exact dimensions.
The other knob is a HMS casting. I'll use it to machine a nice knob part that goes on top of the real dial. I believe the grill piece came from a rpf member. The remaining parts are from a plastic kit that used to be sold on eBay way back when. The pushbutton switch came from All Electronics which is now defunct. I think lighting this one up shouldn't be a problem.
The block of aluminum will eventually become the "grill" for the back of the phaser. I'll be working on that part this month.
