I wanna jump into this chat its gotten interesting!
Paul I am in the same situation with regard to favourite tippers i.e. I've two I depend on and if they beat it! (pardon the pun) I'm scuppered. They were made by a mate of mine the great drum tutor and bodhrán player par excellence,Bob Armstrong. When I was living in London and thats over ten years ago now, crikey, how auld am.
The two I depend on are of the hot-rod ilk. I've tried the hod rod conversion using electric tape but they never hold their shape and consequently their power dissipates when they strike the skin. The one's Bob made were converted hot-rod's but they glued and then had a plastic barrel slid on over the glued area. Very robust, the barrel was a bit thick so he modified them to use a piece of plastic kind o', sort o', hose-like for want of a better term. It was better in that it was thinner and acted as a grip too. With the addition of an O ring you could slide up and down to modulate the timbre, I see Ralph uses the same principal. Bob's tippers are slightly thicker than the standard hot-rod, I've tried to persuade him to make some more but he just doesn't have the time what with his drum teaching, he doesn't even play bodhrán much anymore (A big shame)
I've emailed Ralph a couple of times in the last 2 years threatening to get some of his tippers but haven't followed through. Paul I see you're having discussions with him. Would you be interested in getting the dimensions of my two with with maybe a couple of photos. Might help you along with your plans with Ralph?
I did have one of Bob's in reserve, a kind of break glass in an emergency thing, but it was nicked by some old dear at a session in Howth, of all places!!
Bob has some interesting Bodhrán related stuff on his sight for those interested site address is

Hope it's okay to put the site address here Paul? if not you can move it to a more appropriate place on Bodojo.
Let me have your thougts
