My electrical skills are literally around the plug wiring level, sadly. I've had a hunt around to find out how they connect to the saw, but no joy. Do you plug the saw into them, or wire them into the motor?
In the end I bought an Olson assorted pack, a dozen each of No.s 2,5 and 7, skip tooth, for £12.99 with free delivery, from Hobbies. Hopefully that's enough to get me started. I've been reading loads more of the threads here, seen some amazing work, and feel inspired to learn. What a great forum!
