HELP! Need Full Size drawings for Speed Break Parts

This may be useless as I'm building a Cozy, but...

LB-18 is a hunk of .063 aluminum angle (not bent from sheet), legs at .75" and 1.125" and 2" long. #10 holes drilled three places, the 'axle' hole .625" up.

 

The other pieces are the handle? If so, check the pitch/roll trim chapter. That's where they're dimensioned for the Cozy.

Another option would be to use an electric actuator.

G'day

 

The LB18 would also be needed for an electric actuator. LB18 is how the end connects to the door.

 

I have an electric actuator, but also have the man powered one....that retracts using spring tention when above 95 knts.

 

I would prefer the man powered one.... I may forget either, but electrical failure and mechanical failure are in the electric... Just kind of old school like that....

 

Thanks anyway.... Still looking for some drawings....

 

Cheers!

LB7 is made from a sheet of 0.25 inch thick phenolic. It is a square 2 inches by 2 inches with a 5/8 inch diameter hole in the center (ream it if you can). The edges are beveled back so that the flat on top is a square of 1.05 inches by 1.05 inches.

 

LB8 is also made from 0.25 phenolic. Make it by drilling and threading two 1/4x28 UNF holes 1.25 inches apart. Directly between these two holes, drill or ream a 5/8 inch diameter hole. Form the outside of the part by creating a 5/8 inch radius around the center hole and 0.25 inch radii about the end holes.

 

The shape of LB9 is not critical, but look up the Long-EZ Plans Change LPC#65. The pivot axis going through LB9 is 2.4 inches above the bottom of the cockpit floor and 1.45 inches away from the back of the seat back bulkhead (measured perpendicular to the bulkhead).

 

LB18 is a 90° angle formed of 2024T3 aluminum sheet. The #10 hole is 5/8 inches above the mounting surface. The length of the mounting surface is 2 inches long by 0.8 inches wide. The radius around the #10 hole is 7/16 inches.

Thanks for the help Kinnerhatz! As a follow-up do you know the thickness of the 2024T3 sheet?

 

Thanks again!

The LB18 is 0.063" 2024T3.

 

The LB9 is 5-ply birch plywood, 1/4" or 5mm thick. You can substitute dark red PVC with 3-plies BID both sides.

Great! Thanks again for the assistance! I will be building this weekend...

 

Cheers!
