I think Lappa might be right. Did you check the rollers?
For my CT330x, which is identical, I clean the bed and rollers occasionally (rarely) with metho and turps. I do a lot of pine which tends to leave a bit of gum.

I'd also have a look at the feed rollers. I've barely had anything to do with thicknessers so far, but I'm tentatively going to suggest that might be a flat spot somewhere that lessens the pressure on the wood and results in that. You did mention earlier on that you had a couple of cases of the wood stopping and getting rubber burns because of that, so I'd be having a look at as a potential cause.
Have you tried pushing the timber through, or at least maintaining some pressure behind it to see if it feels like it slips at points?

The "wood stopping" has been alleviated by the application of Silbergleit to the bed. I don't think there's any slippage of the wood going through the rollers now.
As for deposits on the rollers? I don't think the machine is old enough for that nor has enough timber been put through it...

Hi Tccp123, Helical cutter head? No great improvement on conventional knives, they still present the cutter straight on to the wood. What you might like to look at is a spiral helical cutter with carbide chips. These slice the wood and give a much better finish and a lot less noise. I work with hardwoods and have just fitted spiral helical cutters to my jointer and planer and am very pleased. Other issues with your machine should be referred to Hafco but probably boil down to machine set up.
Good luck.

I think you have your terminologies mixed up glueman. A helical cutter is superior to a spiral but companies mix up the names all the time so they’ve all become “spiral helical cutters”. Helicals will present the cutter on an angle to produce a shearing cut but the old spiral cutters have all the blades on the same plane but staggered around the cutter head. This means slightly less noise but no improvement for finish as it’s cutting the same way as a straight knife cutter.

Now that Powermatic pricing through Carbatec seems to be a little more 'reasonable' i think that will be my next machine after my current Carbatec benchtop model. A very big step up.
OP, I faced many of the initial gripes you have had with this benchtop thicknesser. Sounds like you've sorted most of them. I would be putting the last of the 'inconsistencies' down to user error rather than the machine. That isn't a personal dig at you as I still get the odd snipe or stuck board with mine. I think the rollers could use a fair bit of improvement but a good clean every so often with an alcohol based liquid seems to help mine. That cuttingboard you ran through, was the underside flat and jointed before running it through the planer? I remember trying to run a 12" wide piece of non-jointed QLD walnut through my carbatec benchtop model and it struggled immensely to run smoothly, leaving ridges, burn marks, etc. After being properly jointed, though, the same piece ran through like butter!
Regards.

I'm not going to ask how you know what butter looks like going through a thicknesser
If I ever do find out I hope it's not my thicknesser.
Flat on both sides - but how far out of parallel? If you feed the thin end in first all will be well for a while - until the depth of cut becomes too much for the machine.I got sick of sitting around doing nothing - so I took up meditation.

I find that if the machine has not been used for a while, like a week or two, I have to rewax the table as almost every board, except for the very narrow ones, will tend to stall on the feed and need a push to keep going. Once you wax it the machine acts like a different animal.
