Hi Richard,?
Segmented steel infeed and chip breaker and smooth steel for out feed, no screwing around approach.

Hi Richard,
Rubber infeed rollers are a good idea when two conditions exist: ?1) you¡¯re working with soft woods that would ¡°dent¡± under pressure from a serrated infeed roller, and 2) you¡¯re working with really thin dimensional material (under ?¡±). ?I do this kind of work myself - making soundboards for harpsichords out of sitka spruce (soft) with a thickness of 3.5mm. ?For this I need rubber on infeed and outfeed side. ?
If you don¡¯t ever expect to do this type of work (making classical guitar bodies, violins, ukuleles, etc.) you should stick with a steel infeed roller. ?A rubber outfeed roller is helpful if you¡¯re doing any species of hardwood to under 5mm thickness - it will control the flutter of the material better. ?And on thicker material, the rubber outfeed roller will conform to the wood thickness to pull it through straight and without skewing the stock to an angle.
Rubber rollers (either side of the cutter) are a wear item. ?On the infeed side, the leading corner of material pushed into the roller will slightly chew up the rubber before ?it is grabbed and pushed into the cutter. ?Over time, the roller ends up full of score lines and will need to be recovered with fresh material. ? Here¡¯s are examples of what dimensioning cabinets door stiles/rails on edge will do to the infeed roller over time. ?

They are easy enough to get recovered. ?The cost on my Dual 51 to recover both rollers is about $450 and turnaround time is about a week. ??I recover the rollers with polyurethane, not latex rubber. ?Poly has more grip and will not glaze over nearly as quickly as rubber (same is true for power feeder tires). ?If you¡¯re doing mostly hardwood, the a 70 or 80 durometer density is appropriate. ?If mostly softwoods, I would back down to 60 durometer and expect to have to recover the roller more often. ?
Hope this helps.

My Kappa 400 xmotion and profil 45z are on the way over the pond as we speak. im ready to purchase a new Jointer and planer , for the jointer i think i have it figured out im doing the A951L with the Silent power head , 10hp motor , aigner fence and power feeder prep. For the planer im doing the Exact 63 , 10hp , silent power head and digi drive and dual outfeed rollers.?
What im going back and forth on are the infeed and outfeed rollers. Segmented steel , single spiral-toothed steel , or rubber for the infeed and Sandblasted steel or rubber for the dual outfeed??
Thoughts??
