first chips
« Reply #15 on: August 30, 2018, 08:42:33 PM »
after a long time  the old  girl starts  to make chips . The first thing i had planned was the extra  3 step pulley, troubles i i find  the graduations on the hand wheels  are ................ crap !! so   4  aly blanks ordered cut to length  will be collected  tomorrowthen its  the issue of  calibrating    lol
i am really enjoying the path I have chosen to tread

My dial graduations arenít very accurate either. I use a dial indicator and set stops at the correct dimensions. It takes a little setup but itís way more accurate then my dials

Surprising that the handwheels are that far off. Could it be backlash? Sloppiness in the ways? Interested to find out what the issue is.

I would check. I was using the graduations on my tailstock...I haven't verified...but I could swear they off.
There's the graduation on the handwheel...and the markings on the ram.
If I moved the handwheel by 0.1mm...I could swear the ram moved by 1.0mm.
I haven't looked into it (whether the ram actually moved 1mm).  (Could be me.) But it's worthwhile to verify.

there is a bit of slop plus  some backlash  one thing i  need to  do  is to  adjust the gibs in the saddle  plus tighten up the locking ring on the lead screw

My hand wheels are the old fashioned plastic  type with poorly engraved / scratched   graduations  and the only  figures  are 0  1/2 1 1 1/2  if i remember from looking last night   it seems every time i  try to  do  something i  need to  do  some thing else first ,  should i  buy  a new lathe and  forget  the old one  ,,,,,,, noooo  this is part of the fun

And after  stripping and cleaning the 4 jaw chuck  plus  some tweaking with the tool height  the beginnings of a new lead screw control. I must admit its very satisfing watching the swarf come of nice and cleanly

Definitely bring the old lathe back to life, you will be happy in the end. Then get a new one too if you wish. As Jo says, you can't have too many lathes  :Lol: maybe even think about making some metal handwheels.

Bill  this is what  I  am Making  but the lathe tools i  have are  not the best ( new ones on order)  plus my drive belt is slipping ( new one on order)

" note to self,  before assuming the belt is slipping  ensure you have the drive pulley  locking screw  tight  so the  ******* pulley  does not slip"
