Nice! This is helpful.
I'm looking forward to seeing how the head stock alignment goes. I suspect I need to the same thing.

You no doubt know this...keep that sander away from your fine machines.

My bad Stuart. Just went and checked my level, (same as yours) and youíre right, the bubble does travel further. Sorry, Iíve been tripped up on that problem before, it looked like it was happening to you too.

Dave.

Oh no - no worries at all. I very much appreciate such advice, as it helps me to be thorough. I did what you suggest anyway, which has the added benefit of increasing measurement accuracy. By moving the bubble to the center of the range, you get it onto some graduations, so makes for a better reading.

Headstock:



Tailstock:



Pretty close I think. Bear in mind again some parallax error from camera positioning. When looking with your eye in real life, the readings are closer - although not identical.

More good news though - I made adjustments to the headstock using the jacking screws.

After the first adjustment, here are my measurements:



Down to about 0.0007" taper per 4". Not too bad.

After another adjustment:



I think I am now within gauge uncertainty levels (not that I've performed a gauge R and R study), but given that the head stock and mid way readings overlap, and the far end average is .0004" off the headstock end - well I'm just going to declare the lathe as fit for making parts.

Still need to set up the tailstock, which is next. Or maybe I'll machine the new backing plates for the chucks now, then do the tailstock.

I have to say though, I am quietly (not too quietly) pleased with myself for making me go through this.

 :ThumbsUp:

The sander is in a whole different room. Band saw and sander are in the "dirty" part of the shop. Or - perhaps that should be "non precision" part.

:D

I don't buy that. I see the parts you make. That popcorn engine is going to be a cracker. Or is that a popper?  :thinking:

Anyway, this also showed up. A little 2" compound milling vise.



All I'm waiting for now is my Kurt vise - but then that is the end of the money from the motorcycle sale. I'd need to sell another bike to have signifcantly more tooling money - not quite ready to do that. In any case, I'm well set up now. Time to make parts!

That looks very similar to the X feed I have. I love that thing.

Well done Stuart. Once I get the lathe all rejuvinated (cleaned and painted and all lubed up) I am planning on going through the process as well. Thanks for leading the way.

Very nice Stewart!  It's a bit of a pain, but you'll be happy to know you did it as you move forward with parts making.

Thanks for sharing your journey,
Kim

Not yet fellas. He hasn't done the head stock alignment yet.  ;D

No pressure.

Thanks everyone for your support. The input I have received has been very helpful indeed.

No pressure.

You mean tail stock. Turns out that this was the easy bit.

A couple of years ago I purchased an edge technologies tailstock alignment bar. There's no need to go this route of course, but at the time I was afeared of making one. Anyway since I have it, I used it.

The setup:




Zeroed the gauge at the headstock end



Moved down the bed to the other end and...............



Turned the spindle over by hand - the needle didn't move. Well, it sort of vibrated. I didn't believe it so I did it a few more times, same result each time.

So I turned my attention to my new chucks.

I carefully faced the backing plate, then turned the step diameter down ever so carefully, and got a nice, tight fit in the chuck.



Bit of a shame that the counterbores and holes for the screws aren't the right size on the backing plate. Never mind, easily fixed on the mill. Job for the morning.



I did the same for my collet chuck, and by really slowly sneaking up the diameter, got a perfect sliding fit. I can't feel any play at all, so very happy about that.

I now have a collet chuck! I think this will be really helpful for the small diameter stock.



Having cleaned off the lathe and oiled it, it's now time for a barley pop, and some quality time with the missus.

A good, productive day today, I really feel good about all this.

 :whoohoo:

Thanks everyone for following along. A bit of encouragement is good to have.

Excellent job Stuart! :ThumbsUp: :ThumbsUp:

Machine tools are so much nicer to use when setup properly. :)

I find the Edge Technology guys have some helpful things in their line up, and reasonably priced for the most part.
