Furloughed UAL

i am looking at the two pics in this post as i scratch my head thinking about my brain block on where to put my door cylinder. i have a 1'' (acutally, its more like 1.25'') throw cylinder from Ultra Precision. when i put it in the wheel well, i have to move it up to the opening of the wheel, and its kind of in the way if i try to put it at the top (mounting stance too wide) and in close to the wheel if i put it at the bottom.

i was just ready to tack glue in the ply mount, then looked again at this picture.

ooking at yours i am thinking that you have put a long extension on your cylinder rod. is that what you did? how long was the stroke? did you mount it where you did so you would be tied into the carbon cloth?

so, since my UP cylinder terminates in a 4-40 thread, what method are people using to make an extension? the only thing i can think of is to use a bit of CF tubing, screw it into the 4-40 (if i am lucky enough to have a perfect fit) then perhaps add a bit of Q-Poxy to secure it, and add some 4-40 threaded rod to the other end of the CF tube.

or, maybe just buy the robart cylinders?


also, i am a bit concerned about over driving the horn.....how does one prevent that? by perfectly sizing the stroke of the cylinder?

dumb questions but this is my 1st gear door install and i'd like to do it one time only.

thanks!!
