mini ball turner.....
Bernd:
Naw, not to late. Haven't cut it out yet. Have been busy helping out parents with a well pump problem the last couple of days. Got it all working again to day (9/16/08 8:00PM). So maybe in the next day or so.
I do believe my, or should I say the lathes, tailstock is off a tad. :o ::) ;D
Good tip though. I'm going to try a center in the spindle and see if it's off any. Nope haven't ruined my day. I don't get upset over things like that. Besides it's easy to amke another tool post and use this part for something else. 8)
Wasn't sure if you'd mind me adding to this thread since it's your project. Felt a bit like I was interfereing. :-[ I'll keep add ing though since you don't mind. ;)

As I said, I figured this one out..... After I made the mistake with my first one for my 9x20 ::)
Glad you haven't got to re-make anything ;D
I only use it in the chuck due to that being the thing that will hold the work. maybe the spindle centre could differ too?
Maybe it could be a worthy excerise to check all three against each other and see if there is any difference?
I'll leave it up to you ;D I should hopefully get something posted by the end of the week... but no promises! :-\

Damn it... just wrote all this evenings post out and a bodge deleted it..... >:( :'(
Well here we go again!!!
This evening was spent re-designing and modifying the BT base. I am making this off of pictures and supplied measurements. So when I found I had missed a dowel height when I drew up my plan I was not totally shocked!
This is how I sorted it out.... First, find a suitable bit of plate....Brass it is then!
Then make it the shape you need it... round in this case. It was mounted on an arbour after having the corners cut off, then turned until slightly over required size.
the plate was then de-burred and lightly flatted as was the original base. Flux was applied thinly to the steel base and a soft solder spiral was sandwiched between the two parts. They were mounted on an arbour That I already had and secured in the bench vise.
The blow torch was used in an upward direction and aimed at the centre under the brass disc. once the heat has caused the solder to melt (easily visible when the plates get closer together) the nut is tightened to force out the excess solder and create a good joint.
The now tightened and extreamly hot base is left to cool naturally. DO NOT quench the base, the water will force the solder out as it super heats and create a poor joint... It could then seperate in the lathe when finishing is being carried out.
Whilst it was cooling I made the tip holder blank, once it had cooled I turned it to size.
Next I recessed the new base plate for the pivot screw then drilled and tapped the centre of the turret.
So end of play today has this sat on my bench ;D
Oh and I got the new tips too....so very tiny compared with the ones for my BT....
Now at 2am I tink I'd better get some sleep!!! Sorry about the length of the post... So much to say and show!! ;D

Bernd:
Nice post Ralp. That brass and steel sure look nice together. ;D (Eric has to add a few more smiles and the bow)
I see from all those pics that you like to use carbide alot. Interesting.
Well no progress today on my ball turner. :(
2:00AM :o It's only 9:40 as I reply to this, But then your 5 hours ahead of me on the east coast of "over-the-pond". :D
Night Ralph. Sleep tight and don't let the Lathe Fairies bit. :D :D :D :D
