Hello you all,
Now that I still have good access, while the side skins are off, I am installing the control column. The note on the drawing says not to use to many washers, so the control column moves freely. But no matter how many washers (normal or small ones) I use, after I tighten the F-633 control column mounts to the main bulkhead, there is some friction in the back- and forward movement. It?s not much, but the control column does not fall back on its own weight. Unlike the left and right movement, which is really free of any friction. When I have the AN3 bolts of the F-633 control column mounts undone, everything is fine and the controls move freely. However, after I tighten those bolts the bearings seam to ?bind?. I undid the AN3 bolts several times, pushing left, or right while tightening, reamed the holes a bit, put some oil on the bearings, but all this made no difference.
I masked the bearings while painting so there is no primer on the bearings.
Has anybody experienced this also? Is it just the bearings that are a bit tight and it goes away after its been used for a while? Maybe when the pushrods and elevators are connected-up you do not feel it anymore? Maybe I am just paranoid about it?
Any input would be appreciated, I still have good access to the whole thing now.
Actually, I think it was a good idea of some other builder, who made all four seat ribs with the removable part, so he could install and remove the complete control column assembly.
Regards, PilotTonny.
