Retractable step
I used two close-fitting tubes to make a retractable step.
The 1" hole is just above the longeron.
It is easily extended and retracted.
It locks in place into a slotted bracket.
Brake Actuator
Inspired by Wayne Lanza's actuator kit, I also fabricated a bracket for the landing brake actuator. You can get the
approved Electrak SL12-17A8-04 12VDC actuator from www.Kamandirect.com (9307-448-002) or www.McMaster.com (6509K999) for about $170.
I got mine from Kaman for $167. McMaster quoted $178.
The spec is 75# force, 4" stroke.
I turned the actuator around (vs. Wayne's bracket) so the motor is toward the seatback.
The bracket and actuator intrude less on the backseat area, and provide a better
angle for leverage on the belly board. The bracket is held on with 2
10-32 EZ-points. You can get these from Aircraft Spruce.
Using these EZ-points, they stick 1/8" into the map pocket.
NOTE: the installed picture does not include the REQUIRED 2-BID
overlap of the EZ-points, subsequently installed. The dimensions of the bracket aren't
critical, except the width of the fork (21/32") and its offset above the surface (1/2" to inside of fork). I made the
bracket in 3 separate layups of 10 BID bottom, 10-BID top, 8-BID inside.
The first layup, the jog, was over a piece of 1/4" plywood, cut at an angle. 10xBID, peel ply
When cured, layup another 10x BID over a 7/8" foam spacer with release where the fork is.
When cured, remove spacer and layup 8xBID inside the fork.
I modified a tile rod saw to fit in my scroll saw to cut the thick stuff. You could also use a garbide grit blade in the jigsaw.. I like that, too.
To install, retract
the actuator, hold the assembly tight up in place, mark the holes. I found I didn't need much adjustment.
Shirts, etc.
I've had some Cozy shirts made. If you'd like one, please email Lois at lobit@tponet.com.
