Hello fellows,
I hope you don`t mind a newcomer from Bulgaria joining here.
I build loudspeakers and recently sold my Skil router and went for a barely used Hitachi M12V which I bought off ebay as I need to use large roundover bits, like 1" radius and bigger. I read lots of comments on the speed control unit giving up on these. Is this really that common? I have electronics knowledge (I also build my own amps) and am seriously considering to take the router apart as its speed control is in fully working order, spend a few days to remove the conformal coating and plot its schematic. Then order a thick 70um PCB and build a replica of it using very overrated components and adding a 12-15A fuse to protect the armature and field coil should voltage drop too much (the motor will suck more amps until it gives the ghost). Then will seal it in a box similar to the original one with a gasket and hope to have an easily repairable machine. Has anyone tried this here? How possible would it be to buy on here a failed speed control unit to experiment with it before to take on the working one? All this hassle is due to these being somewhat really hard to source and I`m sure many others may benefit from a solution.
Second question would be, how well would a Dremel 3000 do if I convert it to a laminate trimmer? I will use it for excess veneer removal (0.6mm). The Makita laminate trimmers are cheap here, around £55 but I have the Dremel and thought if its possible to use it that way.
Cheers,
Mario
