I love the warm feel of wood knobs and have homemade wood knob on a vintage reel that gets used frequently.  It's Ipe wood.  There are no bearings and the shaft is not stainless.  I put a drop of reel oil on it every time the reel bushings are oiled.

I sleeve my wooden knobs with brass tube .  For the 270 I use K&S #8132  9/32 tube .

The oilite bronzes  are nice, but you could also use Delrin plastic.  Many knobs are made from delrin without any bushings or bearings at all.  The other poster is correct that swelling is hard to prevent in wood knobs, regaardles of the finish

I am not a fan of ball bearings in knobs, as they are far too exposed to corrosion, and I have yet to meet a fisherman that could wind at 20,000+ RPMs to take advantage of ball bearings :)

Good call on skipping the chrome powder coat.  I haven't come across one that lasts very long with UV exposure, so you have to also add a clear coat, which changes the nice chrome-like appearance to more like silver paint.  But they are getting better all the time.

Curious  about the long bake time.  All of  the epoxy/urethane/polyurethane powders that I have used do not require more than 10-12 minutes at temps around 200c. Once they melt enough to cross-link, they don't get stronger, and the clock is starting to work against you.  A shorter bake time is also nicer on the impregnated bronze bearings, and you are less likely to get out gassing of any residual impurities  that didn't make it out in your pre-bake. 

Thanks for sharing.  Your paint job came out nice!

I may have explained something wrong, it could be my German brain typing technical English  ;D
The sandblasted parts were pre baked at 270°c for 60 minutes before I cooled them down, cleaned again and then powdercoated and baked the coating at 195°c for 25 minutes.
For the knob, I like to keep it simple for now and will try the crude wood on metal tech to see if it really will swell this much in use to stop fluid operation.
The shaft is like 6mm and I bored the knob to 6,5 so there is quite some room left at the moment. 

Thanks everyone for your contributions btw.. I'll miss out till mid January, I wish you Frohe Weihnachten und einen guten Rutsch ins neue Jahr!
