Jim,
That is a slick setup you have there. I have a question for you though, what did you make the saddles out of for your cradle? I am working on the same kind of setup also, but I have been at a loss for ideas on the saddle until now.

Thanks for the kind words....

Yokes
I used about 10 inches of 1/2 inch PVC tubing, two 90 degree elbows and one "T" for each cradle. Yoke was assembled with PVC cement, but the upright tube is press fit, in case I want to do something different...

Upright Tubes
Used 12 inches of dark grey 1/2 inch ID x 12" long Schedule 40 PVC sprinkler tubing for each upright (so I didn't have to paint it ).

Support Tubes
Used 1" OD x 9" PVC for the support tubes on the box that hold the uprights. Match drilled the upright tube and support tube to allow the cradle to be moved up in 2 inch increments, held in place with a 1/4 inch diameter spring clip.

Made the support tube attaching cradles out of 3/8 thick plywood, attached thru the box side with #6 flat head machine screws and nylon locking nuts on the inside of the box (holes on the side of the support tube are for access with a screwdriver).

Fuselage Supports
The padded fuselage supports are attached to yokes with 1/4 inch bolts and nylon locking nuts. Would use #8 or 10 phillips heads or pop rivets if I were gonna do it again - easier to tighten in the limited space than hex head bolts - just happened to have some 1/4 inch hardware laying around...

For the padded fuselage supports, I cut 1/4 inch hardboard into 2 x 6 inch pieces and cut 1/2 x 3/4 x 1/16 aluminum angle into 1 inch lengths (pop riveted in place), and attached two layers of 1/8 inch x 2" wide black neoprene self adhesive pipe insulation tape for the cushions -

Materials cost was about $11 - biggest single item was the neoprene tape - $6... If you have some foam around, could do the whole thing for about $5.00.

Exploded pics below -

#1 is a yoke assembly - 2 required
#2 is a fuselage support pad - 4 required
#3 is an upright tube - 2 required
#4 is a support tube assembly and attaching cradles - 2 assemblies required
