Funny how time flies...
Been trying on and off to get my arbor apart, and finally broke it loose with a vise, a pipe wrench, and a big socket with an impact wrench.
I pounded on that thing for at least 10 minutes with the impact wrench before it finally spun loose.
As to machine parts, I only buggered up one sleeve, and one of 12 slitter blades. I did manage to mangle up a soft jaw pad and broke my brother-in-laws electric impact wrench, before I switched to the pneumatic one. I had to clean up the nut a little bit, but all is well.
I've also been trying to find collets when I see them available. I didn't want to hi-jack CoopVA's thread, so I thought I'd ask here. Does anyone know if a "smaller" collet will bugger up or get stuck in the spindle? The one 3/4 inch Hardinge collet I have appears to sit out the nose of the spindle at least a 1/2 inch. The new collet is the same total length, but appears to sit back about a 1/16 when I snug it up. I used a 1/2 inch drill bit in a 1/2 collet to show how the collet appears to sit too deep. I've had the new ones for over a month and didn't even think to check them all for fit.
Progress is slow. The mill is still in the garage, but at least the motor is out for cleanup and made it into a partially heated basement.
Santa brought two sets of dual 500 watt halogen lights, so at least it's bright and toasty warm working in the basement.
