Quote: That is a nifty sliding counterweight you have there. Is that available commercially? Was it an aftermarket add-on? Does anybody know a source for something similar to that?
No, it's not a commercial setup. I had a machinist turn it from a piece of 1.5" brass bar stock. The rest of the setup was fabricated by me. (The whole tale is posted here If you want to take a look.) Hubert
