Good Monday morning....

The J.O.B. is slowing down a bit and that's giving me a chance to get started on the airplane again.  Smile

Last night I was installing the door pins in one of the doors and while I can operate them with one hand I still feel like they're tight.  I put a slight bend in the rear pin but that didn't seem to help too much.  The only thing I can figure is that it's simply drag between the pins and the delrin blocks.

Is there a lube that others have used to free up the friction?

I'm using Sean's kit if that matters.

Thanks,
Phil "Finally back to building!"  Perry

I put a few drops of Triflow on mine, but Boelube is probably just as
good. Mainly want something that is a dry paraffin or silicone type
lube, that won't attract dirt.

I've been using lithium grease on the pins now, done maybe
2-3 times a year...but I only started last year. I was
amazed at how much easier they operated.
I'm sure other greases would work too. Lithium seems to
clean up easy.

Do yourself a huge favor. Toss the delrin and get the aluminum. You’ll find the door will close easier and it will be much more secure than the Delrin blocks.

Delrin is NOT the problem. UHMW that Vans supplies is the problem.
Specifically the pin guides on the door itself. Delrin is an
excellent self lubing material, much more resistant to wear, harder
material than the UHMW. Does someone offer pin guides for the door in
other than Van's UHMW? The stuff that Sean and Steve(iflyrv10) are the
door frame side guides.

My door pin guides (180) kit and my fuselage guides come in Delrin.

Phil.
It is probably not the Delrin. Does your handle turn easy if the door is open? Do you think it is the alignment on the fuselage guides or the door guides? If it is on the fuselage try paralleling the pushrod movement into the fuselage guide with a 7/16 reamer. Feel free to call me. I have done a bunch of these.

Yeah - Sean's kit is delrin.  It's much nicer, smoother, and harder than the UHMW that shipped with Vans.

Sean,

It's still simply sitting on the bench.  I haven't bolted it to the airframe and drilled those holes yet.

I dont have my computer with me so I can't tell you you bought the 90 or the 180 kit. If you want the delrin sleeves for the door guides Let me know. They come with the 180 kits. The whole mechanism should have little drag even after everything is installed with the seal in place.

I'm a 180 kind of guy.  I think it's simply friction because they are pretty firm to push on.

Do not!!!!!!! Get silicone any where near your unpainted aircraft. It
causes fish eyes when you go to paint, and it migrates everywhere.

I opened the holes on Sean's kit and on Van's uhmw/bulkheads until friction was where I liked it. If you don't take care of the increased drag of the doors now it will really increase once on the plane. I also took a chunk of boelube and rubbed it across all gear teeth then used a propane torch to melt it in slightly before final latch assembly(no fiberglass nearby during this procedure). Smooth as can be now. If you look back in the holes in the airframe once your doors are on and latches actuated, you will notice areas that are darker than others. Those are the areas to take down some. I sanded with 180 then vacuumed holes out. I put a small amount of vaseline on mine. Hey, whatever works to decrease the friction right? My doors sitting static are 1/4" away from cabin surface and I can close with thumb on the button release and one finger on the handle. Thanks again Sean for my extra safety latch that does not stick out of the door exterior and require another hand to operate.
