The wobble in the lathe center must be the jaws on the chuck. I trued them up and they are dead center but the center still wobbles about 10 thou until I monkey with it and straighten it out. It irks me a little but this is not a $20,000 metal lathe. Don't get me wrong, I think the lathe is super.
I pm'ed the forum moderator to see if we can get a page set up just for cuesmith lathe owners. I think it would be great but I haven't heard from him yet.
My pwr switch only lasted about 2 months. I found a drop in switch on the internet for $7. It is dust proof and no more problems.
I only rough cut both directions. I always cut right to left on finish cuts.
I got an excellent finish on my second cue.... I can give you that info if you like.
I use a 7/32 straight bit for ring billets and buy 1/4 thick pieces from Bellforest. I run the 1/4 inch pieces thru my jointer/planer until they are the correct size. That makes pretty large looking inserts but they come out nice. I will work later on the finer stuff. I am still learning. There are places to buy 1/8 small slabs also.
I believe I will stick to an "all wood" cue that is cored. (except the joint pin) I am just finishing my 3rd cue.
I cut the rings with the cutoff tool. I tried the circular saw but it was a cheap one and cut crap. With the cutoff tool there is more waste but the rings are true and exact.
