??? ??? If it's out side to side ya move the tailstock in the direction that gets it on point? ( no pun intended )?

??? ??? If it's out top to bottom ya need to shim? the tailstock .

??? ??? That last pic looks to me like it was taken at a angle so in that case ya may have to do both . Have ya checked to see id teh headstock is on the bed straight & not tipped up , down or sideways ? The mention of rods from a printer is a good one

1st a thanks to those who suggested my Speedway 7x12 speed control issue was most likely a bad pot.? I replaced it with some major surgery and it¡¯s fully recovered and working like new.

Next problem is the unwanted taper I get machining stock longer than a few inches.? This happens whether I¡¯m turning between tailstock and 3 jaw chuck or between centers.? I¡¯m not a machinist an have no idea how to solve this issue.

For measurement I have a magnetic stand and plunger dial indicator.? But how to use them to solve my taper issue is a mystery.

Is the an easy way to achieve?this?

P.S.? I use my lathe in building bamboo fly fishing rod hardware.
