mini ball turner.....
Bernd:
Actually Ralph I own 3 saws. Two grizzly bandsaws and a powered hacksaw. If shipping and taxes weren't so much I'd be willing to ship you the hacksaw since I don't need it any more. ;D
The part was salvageable by the way. I just milled the bottom and rescribed the lines. Now all I need to do is cut it out, finish mill and add the cutter and I will have a ball turner.
Thanks to your persisten nagging to get it done. :clap: :clap:
Also watch HMEM for my next engine build. I'm going to show how to use a sacrificial aluimnum milling table. It'll be a while yet though.

Ok then.... On with the show!!
Just to make it clear... I am not (against popular belief) perfect.... :-\
The pictures already posted show the turret made to 40mm dia. this has become an issue when the drillings for the fixing points were made. They cut into the edge of the recesses and made small but noticeable swarf traps... This will not do.
So last night I started re-making the turret, larger50mm dia and re-machined the base slightly to allow the bolt holes to be within the recess for the turret.
A few pics to get me up to date.
new part cut (by hand!!)
the part faced and then the outer edge cleaned off using super glue gel to hold it to the chuck.
The part removed, the chuck and part clean up easily.
The part sized and ready for a little lapping. I put some blue into the grinding paste so it would photo' easily :)
To lap it I used a fixed centre against the brass base and applied pressure via the tailstock whilst the machine was running, you know when the lapping is being done as the bit you are pushing stops spinning with the one in the lathe, This may not be the best way to do this but it worked... And just a little cleaning up on the base where the centre was pushing it. (this might not work if the base were steel?)
So as of last night I have this to show for my efforts...
Hopefully i will get some meaningful work done on this very soon. It has to be finished.
How's yours going Bernd?

Well I put some time into this tonight.... Got the new turret mostly finished.
It was all about the setup.... the machining took min's!
Tool post slot.
Relief for grubscrew holes.
Handle hole
Grubscrew holes
Where we're up to....
A piece of square machined 1/2 " ali plate has been sent off to the new owner so that it can be marked using a sharp point turned in the 3 jaw ... Slide the plate across the point whilst holding it firmly to the saddle and it should give me an easily transferable (via height gauge and surface table) scribed line.... Just waiting on it's return now!!
Ralph.
Brass_Machine:

Bernd:
