I purchased a Sanwa Bat top and an adaptor for my JLF.
Unfortunately, the bat top doesn’t stay screwed on.
I know how to replace ball tops and screw them in securely but the bat top keeps coming loose.
I have tried any combination of these different ways to screw on the bat top:
Screwed on the adapter first, tightened it and then tightened on the bat top
Tightened the bat top on the JLF with the adapter inside of it
Installed the bat top without the JLF shaft cover
Installed the bat top with the JLF shaft cover
None of these combinations have worked for the bat top however, ball tops are secured just fine.
Any help would be appreciated,
