开云体育Wow. Lots of questions. One fact is really obvious. My machine operator pair should take cuts 10x deeper than I am.
The lathe head and all associated gearing is good. It was recently rebuilt and all pins, etc. were replaced correctly. Of that I am pretty certain. The drive unit moves freely, was also rebuilt, and operates correctly.?
Speeds are from the ebay chart I bought. The HSS tools I grind are based upon lots of videos I watch. I bought a jig to help get the angles correct. My carbide are inserts, many are still the original chinesium, but are being replaced
by higher quality as they die. I use a Boxer quick change toolpost.
Now, here is where I feel the problem lies since I do not have the power to make deep cuts:?
I use a link belt on the motor. It slips especially as oil gets on it. The bearing in the drive unit slings oil. The drive belt to the lathe head is a serpentine auto belt. It seems to transfer power efficiently. The drive unit is mounted
on channel so it's adjustable.??
I am wondering about switching to an auto v-belt for the motor. Next, could the channel be flexing? It is the kind used to support conduit.

What sort of carbide are you using? I've never had good luck with the 0 degree rake brazed carbide. I hear that it wants to run really fast. On 6/25/23 14:24, Brandon Corey wrote:
