Hi all,

I inherited the 12” planer and it was working fine. Now the drive is inconsistent. It seems like the tensioner on the chain drive is not doing its job, though that’s only my impression. The wood will feed then stop, feed, stop, etc. I opened the side case, cleaned and lubed the chain, but no difference. I also reversed the blades getting fresh, sharp edges to work with.

Another problem I’ve always had, even when it planed properly, was that I needed to push and pull the lumber through the machine, as it would otherwise slip or not drive through at all. I expect this is typical and do to the 10” red oak size and hardness.

Please let me know if anyone has had similar problems with possible solutions.

Thanks,
Dave

One more important symptom I forgot mention: The “skipping” sound occurs even when there is no lumber being fed into the planer. It’s as if the chain is jumping a tooth on the sprocket, or maybe the spring tension is going slack then suddenly catching up. Dave

Clean the rubber rollers with mineral spirits and see if it works better. Buildups on the rollers will cause inconsistent feeding.

Chains and sprockets do wear out, expecially if they haven’t been lubricated periodicly. If the tip above doesn’t help it may be time to take the covers off. Many planers have chain noise since they don’t have tensioners to keep the chains tight as they wear. If it still skips when feeding a board after cleaning the rollers, then you may need new chains, and or sprockets.
