Marv,

Was wondering if anyone has substituted a Mac servo or similar device for the
cable-actuated oil cooler door/flap on the TSIO 550. My rationale was to
eliminate a cable through the pressure bulkhead/firewall and perhaps(?) save
a bit of weight. Comments/thoughts appreciated.

Have just completed and tested a rotating "spit" for our fast-build
fuselages. Consists of a square tubing/pipe assembly that bolts to the
firewall in place of the motor mount, with the pipe sticking forward--a spit.
The rear support consists of a plywood disk that clamps around the fuselage
forward of the tail assembly and runs on two boat trailer rollers. Used the
Lancair-designed 4x4 support posts/feet, but widened the rear one so the 30"
plywood disk could fit within the vertical posts. I'd estimate my total cost
was about $120, with half of that going for outside welding.

Haven't yet used it for actual work on the fuselage (a week or two away), but
several observers have offered to bring marshmellows and barbeque sauce---
Could try to send a digital photo if there is any interest.
