Hi Friends,
So many makers use Delrin for the fipple plug. Is it available in round stock like dowels?
I would like to find something other than wooden dowels for my copper whistles. (Wooden dowels don’t come in the right size anyway. I’ve been using oak.)
I don’t have a lathe, so if round Delrin stock is available, please tell me where.
Thanks,
Phil
Check your PMs, Oreo.
It comes in quite a few sizes. I use .500" rod for my fipples and need only sand them a TINY amount on the lathe to have them fit perfectly.
If there is a TAP Plastics near you, they carry it. The generic name is acetal. Delrin is a brand name.
I understand you can get tube stock over there too, lucky bastards!
Check out onlinemetals.com.

What tube size is good for a high-D?
I’m thinking the:
O.D. = 0.625
I.D. = 0.500
Wall = 0.062
???
Yep. .625 - .500 = .062
Allwais cheque you’re math and speling.
Jubilee Musical Instruments has a program called TWCalc that lets one really play with the dimensions before construction. Fun, too!
(.625-.500)/2 = .0625 actually. Remember, 2 wall thicknesses.
I typically buy 5 to 10 foot of delrin at a time. I get it from US Plastics in Lima Ohio. Most plastic suppliers handle Delrin or Acetal, it’s best to find a local supplier to keep shipping costs down.
If you specify to buy it in 5 foot segments, it can go out UPS and the packaging is cheaper. Longer segments have to be special delivery or by truck.
There is a Delrin bushing stock, which is pretty thick but I haven’t seen any tubing.
Krapp. My spelllling and mhath bight badd.
