Hi, new to the forum and new to owning a lathe. I recently got a Logan 12" and have been learning to use it. I decided to try a test bar and get my tailstock lined up which i think i had gotten pretty close but in doing so discovered i was getting a pretty big taper towards the chuck end for about 3-4" then it straightened out and had about a half thou from there to 9 inches.
The measurements i got on one test using the tailstock were:
0" - 0.8447"
1" - 0.8510
2" - 0.8523
3" - 0.8514
4" - 0.8497
5" - 0.8498
6" - 0.8496
7" - 0.8496
8" - 0.8494
9" - 0.8497
On a shorter piece with no tail support i got the following:
0" - 1.9294
1" - 1.9352
2" - 1.9381
3" - 1.9382
So in both cases im getting a good bit of taper towards the chuck and straightening up after a few inches. I checked for bed wear using a technique i saw on here putting a dial indicator on my tailstock and sliding it along with the indicator on the carriage ways, flat and V ways both showed about 5 to 6 thou wear difference between the tailstock ways. The wear was greatest right up closest to the chuck and kind of matched the results from above in that it seemed to really come in most around the 4" range from the chuck.
I didnt think this really seemed like that much wear compared to some other posts ive seen. What do you think about this scenario? Is there something i can do to help with the taper im getting towards the chuck end? It seems im getting more taper than id expect for the amount of wear it seems to have. Maybe something else i might be doing wrong?
