Re: Plastic components

Tim apprenticed under Larry. I had given some thought to the delrin rockers after talking to Larry about his inserts. I didn't know he quit using it, he seemed happy with them when I talked to him. My one concern is I've heard delrin cannot be glued to. I didn't look into it enough to verify or disprove that.

Re: Plastic components

What about stabilized wood? When that's done right it completely eliminates seasonal wood movement. I've seen some pretty substantial turning blanks that were stabilized with acrylic resin and the resin had clearly penetrated the wood entirely throughout.


Re: Plastic components

I hadn't thought of that. That would probably work pretty well.

Re: Plastic components

Bryan, I stand corrected on the Delrin rocker inserts. The rocker blocks cannot be inspected without complete dissassembly. I just took the keyboard off my Bon Cajun, and I can't see the axle contact, so I must have assumed that the blocks were solid wood, after diddling with the springs a while back. The key action is good year 'round, so whatever I've got is working.

Re: Plastic components

Yeah, you'd have to take the rocker out of the slot to see.

I tried the delrin thing, but it was a pain, and as far as I know, I haven't had an axle seize yet.

Re: Plastic components

Nedro I was about to ask you what year your accordion was made but I finish reading all the post, I was gonna say I've taking an apprenticeship with Larry for over a year now and he still uses Delrin in the rockers. Well has recently retired last July from building but he still doing repairs and tuning.. My first accordion I didn't use it, I said from now on I would. My opinion is the tolerance is tighter between axle rod and rocker than it is between rocker fingerboard. So to me if you gonna have any swelling the axle rod would be where to go the extra mile. Also Delrin is inexpensive. But on the other hand I haven't experienced any sticking so I havent decided if its worth it or not. Does anyone know if any other builders have use it?
