Leonard, Blud Sr., passed away years back.
His son was running an eBay account for a while.
I bought one of his dad's sneaky Pete's that he put up for auction. He had half a dozen available.
I contacted the son via eBay messaging, regarding the cue being 16oz, after having asked for a 19-20oz cue.
He responded immediately, and sent me 1 of every style and size weight bolt available. Probably about 10-12 bolts. I thought that was a great gesture,
but also let me know he didn't have the same extensive cue knowledge of Blud Sr.
After discovering that none of the weight bolts fit, I ended up selling the cue to a friend.
You might have to get a set of 3/8x11 JP's,
and force screw it down until it's created it's own thread groove. Or, maybe proficient billiards could help.
There are guys on here that make beautiful joint protectors professionally. I'm sure one of them could help. Tony Lane would be a great guy to start with.
His work is very nice.
Jim Baxter might be able to help as well.
