Or are there any plans to make a new ones? They were last made in 2009 I think.
Mike Hartman is the guy who made them before. He's in Ola, Arkansas.
Will send him an email and report back here.
There was a used one on Ebay, recently. It may still be on the auction.
every once in a while I have seen very good ones for sale, but most are totally worn out. I bought two used, but thought twice about using them - bad shape. I ended up buying new from Mike about 10 years ago.I was very impressed with them. Still don't have the TT on the road, but it's getting close.
Mike Hartman plans to make new sets in the 1st qtr. of 2016. The sets sell for $1840 for both ring and worm.
