Air cylinder plan

Danny - items to check on

bellows length, confer w/ SG => need 1.5" travel, has 1.7" stroke, seems okay

air cylinder exhaust adjustment/tool => hex key to adjust

Longer rods (i.e. we will not modify hex shaft length) => Shaun completed layout, Danny will verify dwg, submit shop (10)

7/16 to 3/8 turnbuckle (i.e. we will not modify hex threads), we prefer/want split but can start/try unsplit+lock nut => have (3) 7/16 to 3/8 split, need (7)...Danny/Phil will look over print, fabricate (>7-10)

Piston stops => probably have enough, Shaun will order 10

Spring centering cylinder => submit order to shop for 10

Update drawings => add to list of dwgs to update for documentation
