bar. I had read several message threads here about potential fixes but so far as I gathered no one had arrived at one. I had contacted Felder about it and was assured it was nothing abnormal, and there was no particular fix for it.
The squeal?only happened for me when taking sequential passes on boards, not on a rough surface, so my thought was that the drag of a smooth board on the pressure bar was leading vibration in the entire bent metal bar. I found that i could temporarily alleviate the problem but putting paste wax on inferior edge of the bar, but that only lasted so long.? So I did two things. First, I attached a thin layer of foam to the surfaces of that metal bar in areas where it wouldn't interfere with any moving parts. I used some left over shelf liner material to do it. Then I filled the little crevice created by the last bend in the metal plate with hot glue (the area circled in blue on the diagram). Those measures really dampened any vibration in the plate. As a final measure I put a piece of Low Friction tape that I got from Lee Valley along the bottom edge where the bar rides along the wood.? I'm not really sure which of these fixes was the one that did the trick, I'm guessing probably the low friction tape was the key given the paste wax experiment, but between all those measures the high pitched squeal is completely gone. What a relief, it was driving me nuts.? Anyway, thought I'd share in case anyone else out there is having the same issue.? Incidentally, just placed an order for a k700 slider, so i'm sure i'll be hitting you all up with questions in a few months when this thing arrives.? -Dave |

Re: Langzauner Sander Delivery - Warning on Machinery Max Palletization
I know its not as 'professional', but this is why i prefer Ushippers with a janky trailer and missing teeth. Direct transport from pickup to drop off typically offers less chances for bumps, drops, or other oopsies. Is the door on the front jacked up now?? Thankfully, with most high end industrial machines, you really have to be a bone head to truly hurt them. Other than the front door being bent, i doubt the 3.5" fall to the side hurt it. Sorry, man, shipping machines sucks. Patrick On Thu, Dec 17, 2020 at 1:37 PM David Kumm <davekumm@...> wrote:

Re: Langzauner Sander Delivery - Warning on Machinery Max Palletization
Wow, that's bad. Especially since you already had the conversation. I can't remember any time MDF was a suitable structural subfloor over an "open top" pallet,?though I have seen it as just a "scuff pad" over a proper?structural?top. I'm also surprised the pallet top boards aren't?hardwood at least. There's a lot of cheaping out there if you paid for palletization, in my opinion. For the amount of money involved, I'd strongly consider suing to get your "buyer's premium" back.
