Hi Richard,
I have the 531 Felder & it was sticking from new. After several calls to tech support & adjusting rollers etc it was no better. I too used the "super gleit" but it only lasted a short time. I eventually threw the toys out the pram & called the M.D & told him to put my money back into my account & come & collect his planer. That got his attention ! Within the week, i had an engineer come the whole length of the country to fix it. At this stage i did not know that it was a problem with the surface of the table & thought it was a roller alignment problem. When he checked the heights he told me they were spot on. Then, without even trying a piece of timber through the planer, he flooded the table with the super gleit (this tells me he new what the problem was all along). Of course, the wood went through no problem. He did this a few times, lubricate then 3 or 4 piece's of timber through no problem. I was gobsmacked & couldn't believe it wasn't sticking. It was only about an hour after he left that the penny dropped that the only reason it worked was because of the super gleit.
They did send me up a tin of a type of wax with graphite in it. It does last slightly longer than the super gleit, but not much.
I did toy with the idea of taking my sander & smoothing the table a bit, but Felder maintain that there needs to be a certain amount of machine marks for it to work properly. All i know is if i am dressing a lot of timber, it is really frustrating to have to stop every 10 Min's max to lubricate the table again.
Could you post a link to the other FOG site please.
Thanks, Woodguy.
