Adapting a Bedair Ball cutter to a 7x14 Seig

Hi chuck :wave:
Just found this thread..... Been distracted/busy as usual these days.... ::) Anywho...
I don't know if you found this thread?

It was made for a 7x12 as stated and shown etc..... worked first time too!!!
If when you come to turning your first ball and find your getting more football shapes (American style that is) then I can help you with that too... Been there done that :doh: I have links available where I tried my best to explain the set up procedure that I used..... it seemed to work well for me :thumbup:
Can't believe that you haven't much used your tool post John (Rudd). I use mine for all sorts of shaping and creating :dremel:
Maybe you could chuck up a piece of bar and just let the tool allow you to create some smooth curves just for the hell of it? Alter the cutting tool distance etc and have fun with it! It might help open up some creative channels in your mind? :ddb:
Looking forward to seeing another take on the idea :)

Got all the way to making the tool holder. My attempt at drilling the hole for the tool bit went awry, and the tool bit ended up way low. Back to the drawing board....
Man, I need a mill....
Divided he ad:
If it's the tool posts height in the turret that is the issue? Why not try to solder/screw a plate to the bottom of it to raise it to the correct cutting height?
A few piccys would help us all understand the issues!
:worthless:

Made another attempt at the tool post bit. I carefully squared up my stock 7X tool post and put the tool holder in it. With a 4 flute end mill in the 3-jaw, I squared the hacksawed ends, repositioned the blank and milled the "L" shape. Much more square and better looking. Mounted the "L" in the turret and squared it with the chuck. Center drilled and through drilled for the tool bit. Repositioned again and drilled the hole for the set screw. Now the tool bit sits on center.
New problem. I cut, faced drilled and tapped a 3/4" piece of aluminum round for my first ball. Problem is I didn't mill the base of the "L" low enough and the tool bit will not clear the ball blank.
I have really learned the value of design, and keeping to dimention, even though I'm working from generic plans for another size lathe!
Another problem I have to solve, is getting the turet part tight enough to eliminate slop/rocking, getting it to stay adjusted, and still be able to rotate it. I used a socket head screw to hold the turet to the base, with a brass washer under the head. I can tighten the screw untill the turet just turns, but the screw will loosen every time! I did not cross drill the screw for the weed eater string as Ralph Peterson did, don't have any on hand at the moment.
I have little experience in these things, and am open to suggestions.

My ball cutter was a bit stif to rotate and a improved it with a taper bearing

As to the ball not clearing -Try a small bal first to prove the rest of the design and if the rest is ok then mod that part - Otherwise you could spend a lot of time modding that and later find somthing else dont work
