You guys will probably think this is a bit crazy too but I had to try it. I was showing a friend who owns a medium size machine shop (with 5 Hurcos) some emblems I've made on my X2 and asking his advice on one or two things and he started laughing when I told him my RPM was ~4200 for .0625 and .0469 end mills.
He said I should be spinning those at more like 20K to 30K ! So I've been on a hunt to find higher rpm motor to replace the stock one. No luck in finding one yet so I went ahead and did what I had been thinking about and mounted a router motor on the X2.
I used a Bosch Colt palm router with variable speed of between 16K and 35K rpm. The result, well it worked and I finished making the emblem in the pictures but man was it loud ! I had the speed dial setting on only 2 and it sounded like one of the old Cox .049 airplane engines. And the router got quite hot, I had to aim a fan at it. Also, I did get my spindle bearings to loosen up and run allot cooler before doing this, I now have taper spindle bearings that will be going in soon.
I'll be removing the router tomorrow and going back to my stock motor until I find a suitable replacement. So at least now I know and can put this idea to rest.
Here's the pics...
