I bought my Makita off fleabay, they're expensive so you just have to be patient and catch someone not paying attn.

I got a single speed and bought a router speed controller, dont be ghetto and use a dimmer switch.

My favorite burr is the middle one with the real tight spiral flutes, it's doesnt chew through the material as aggressively so once you get a good amount of material removed I 'll swith to that to start smoothing and go the the sanding mandrels.

Don't even bother with 40 grit, 60-80 on the intake side. you dont want it to be (mirror) smooth, and if you want to make it pretty on the exhaust side a 120 but no more than that IMO.

I was just looking at the Buckeye Carbide site and their prices are good!! Now I know the difference between a double and single cut bur. Going to pick up a couple single cut burs here shortly. The egg shaped 1/4 shank, 3/8 dia cutting, 5/8 cutting length at 6 5/8 shank length and the same one but in a 2 3/8 length. Going to look at a few others as well. Thanks for the info!!

Ok, back to thread topic..
