oh no another ball turner

Not necessarily Lew... Mine is held together with just a screw. No loctite, no locking devices of any type at all.
I simply made the screw too long to fit the job (very important not to drill right through the turret) then file/emery it down a little at a time till it bottomed out and the (lubricated) turret would still turn freely but remain firm. It's held well now for over 3 years and there are plenty of projects pictured and filmed to show the lack of chatter and the abuse I throw at it (most of my work is in stainless)

A thread I put some pic's and ramblings in, just my experiences.... please note the bottom pic, I think it's quite important to get the parts lapped together.
Just my notes :)

When I get about finishing mine, I am going to go with Ralphs' idea with filing the threads on the bolt. I think Steve Bedair also said to crimp the threads or something like that.
Nice job designing it.
Did you already tell us what the shift knob would be use?

Hi Jason
A simple piece of brass insert made to a close fit would make it so that you could lock the screw and then the force would not be on the screw any more. Should make it turn easier as well.
COC Forgive the diagram

Thanks again guys :thumbup:
I'm convinced the screw shall be easiest for me so I'm going for that
Brass_Machine The 50mm ball will just be a gear knob for my car and then balls for everything else like my lift at work,and other machines with cheep plastic knobs :D
I also have a daft idea in my head to make a flip top gear knob that either has a secret compartment inside or a switch ::)
Divided he you say "I think it's quite important to get the parts lapped together"
Do you think automotive valve grinding paste will be any good for this ?
Or will I need something finer.

Hi Jason,
Valve grinding paste was my choice for the job, (the fine side).
There are a few pics in the thread on the mini version I made a while back... http://madmodder.net/index.php?topic=319.msg803#msg803 Bout 8 pictures up from the bottom will explain all I did.
Flip top gear knob eh?? Has all sorts of uses.... Switch for the nitro I'm thinking!! :ddb:
What motor you got?
You know we're expecting a few pics of the build don't you? :worthless:
:)
Ralph.
