Anyone thinking about making speakers should take a look at the Deal of the Day at Parts Express (expires today at 5 p.m.). Yes, you can cut holes without the Jasper Jig, but for me life's too short and I'm too lazy . . . Jasper Jig Combo Pack at PE
I took Epstein's advice and made my own jig out of a scrape piece of 1/4" MDF. Total cost: $0 and 15 minutes. Not to knock the Jasper jig (it's a nice assessory for your router), but I'm not cutting holes that often. Gar.
I was waiting for this deal to come around again, thanks. My plan is to mount one on my roto tool router attachment and save the bigger one for an actual router. Last go-round on deals at the local tool superstore I got the spin tool and have actually made the thing work. Some problems handling stock like not having the right hold-down and clamp setup so it's a good thing I have spares blanks to finish off my project. The router attachment is made of some sort of cheap white metal and I'd have to match up a set of mounting holes on the Jasper by tapping the base of the router attachment. Does this sound impractical to anyone?
I actually had the idea of getting a small lucite cutting board from the Farm and Fleet or someplace and doing likewise. Bill, can you provide details and tips? The Jaspers are made for precision in 1/16 increments. I can see that if the builder was working with few driver types that some standard centers could be used without the 1/16 machnings. But when routing rabbets, those 16ths might come in handy.
