Delrin as a material

[Pumpkin the robot]

I machine it alot and never struggled to deburr it, I use a surgeons scalpel. We recommend it to a lot of customers instead of Nylon because of its machinability.

I have just seen the price of these in the first post! I think I can see a new side line coming in at work if people are willing to pay that for them!

Yep we used a scaple as well but it was a small bevel gear (19 /20 dia from memory) and any indents and scapel marks the edge of the teeth was a instant fail from qc.

I run swiss cnc and can / could do alot of bike stuff (we do titanium stuff as well) but work is not interested.

I used to run RC cars that used delrin spur gears- tuff stuff.

Gonna ask, how do you get on with the KCNC stuff, i.e. no float - I suspect fine as running DI2

Got Tacx jockeys on the MTB that are sealed cartridge, but they work fine in tough conditions.

I am still running my original DA 7400 jockeys on the best bike. Ceramic bushings, alloy top jockey teeth - fabulous bits of kit, yup not super light, but 22 years of use with no wear....

the ones you listed but the Delrin Jockey wheels come in at 9g a pair which I think will be hard to beat.

Your realise you are looking at paying nearly £ 100 to save maybe 3 g.

I am aware of this.
