Like Sheldon... I used a 3 wing for years with pretty good results. A while back I was in Woodworkers source and they had a table full of odd bits for cheap and I picked up a bunch of 2", 2 wingers for 3-5 bucks each and figured what the heck. I'll never go back to anything else. I sharpen all my bits myself and found that the two wings are much easier to keep sharpened with both blades hitting the same depth. The thinnest ones(1/16" kerf) I have are the ones that work the best for me.
Could not find an arbor that was worth 2 cents so I made my own from SS and brass. Far less runout than any mass produced that I could find.
I found for me that the worst cause of chatter was dullness of the blade.
As soon as there is any hint of anything but a baby butt smooth cut off to the sharpening stone. I have also modified my angles of the cutting carbides to my liking other than the factory angles. I can easily shave 1-2 thou off of any diameter as needed with no chatter involved.
Many years of fine tuning speeds, feeds and using a router(very key instrument) that is worth what you pay for has some of the smoothest cuts I've had in the last five years.
If your using a laminate router..ie Porter Cable......good luck.
If you have an old one lying around... tear it apart and do some investigating as to how they are put together. I am not saying that they are not any good ....but they're junk! The bearings and armature are mounted in rubber! Was very hard for me to get an accurate cut with the way they are designed. Most lam routers are close to the same.
A quick hit with 400 after my final cut.......600,800, apply my sealer...
Leave like this until final finishing techniques.
Good luck.........
Thanks for the info Dave,
They had 1/16 also but they were 3 wing too, besides them having no mandrel, I guess I was alittle frightened by them being so thin, and fear of one coming apart or something also.
I think My old bit is just dull, because I had the speeds working for Me before. I have had My router apart, and aggree on the bearing casings, the dremels are pretty much the same way. Another source of runnout can come from bottoming the shank out, so It does'nt center in the collet perfectly, I think your suppose to leave something in the range of 1/8 spacing from the bottom. I use a dremel for inlay also, so I have simular issues with It. I keep rechucking the endmill until I can see no runnout, and that seems to work for me. I plan on replacing that spindle in the future with a premium one.
With all that said, somehow the porter has worked well for me so far, and I can usually go from 400 to 600 as you mentioned with handles, so that's what I'm shooting for with shafts, but i'll have to see what happens. I would however like to have a nice spindle for that also, and will when I can spare the cash to afford one, for the reasons you mention, but most of all, the noise level is killing My ears. I had to buy a set of ear muffs, because It was giving me ear aches.
Btw How much for a Kress spindle? anything decent and quiet that I have seen is a grand or over usually. I guess it's just one of those things that are still a luxury for me, but I definatly want to upgrade.
Thanks Again, Greg
