After the carbide grinding and a quick evening with a cartridge roll you can apply it to the walls and go bac over it with the cartridge roll on the slowest speed yu can dial it in to. what you're going to use it for is a lubricant.
The nonscented, plain jane, cheapest crap you could find kind. You need it to control the speed, and speed control is very critical.įinally you need to get a cheap tube of chapstick, maybe two.

Those are about $10 and this is another item where people will say you can skip it but they are full of bull. While you're there you need to pick up a rheostat too. The unit itself is on sale from time to time for less than $30. The long nose one that Harbor Freight sells is actaully pretty stout and you can get a 1 year warranty for an additional $10. Dremels aren't worth sh1t when it comes to this work. You also need to get a solid 1/4" electric die grinder- NOT A DREMEL. Get the 3M 1/2" straight reglite (orange) cartridge rolls, and a 4" mandrel, get two mandrels incase one bends, they're only like $2 so its worth getting an extra though I have 3 mandrels tat have lasted through a lto of work so far. I have about a dozen bis and I use these two 95% of the time. If you want you can also get a 3/8" tree bit on a standard length shank, this one helps some but is not totally necessary. You don't need more than 1 carbide bit, having two make its easier but you can do anything yu need to do wit a 3/8" double cut round nose cylinder bit with a 6" shank (cut the shank down to 4" before you even think of using it though). They cost about 30% more but last about 3 times as long and have a much more consistent finish. I made the mistake of getting one and after hat I used 3M reglite cartridge rolls and the 3M ones are the BEST I've ever used.
