LOC Stovi Question

Post by muchi » Mon, 18 Jan 1999 04:00:00

The LOC Stovi uses a 3" dia main (bottom) tube and a 2.25" payload
section with a transition unit that is about 8 inches long. At each
end, about 2.5" goes into each tube. The plans say to epoxy the
transition unit to the payload section and use the main tube for the
shock-cord mount.  29mm engines will be used.

I was thinking of using the transition piece as a baffle system, but
am not sure how to go about it.  I would have to cut (or drill) some
holes in both ends of it, and then epoxy it to the main (botom) tube.
Then use the the transition itself  for shock-cord mount.

Should I cut some semi circular channels 3/16" to 1/4" wide, and 30 to
45 degrees long? (At the forward end they would be about 1" long, and
1-1/2" at the aft. I would stagger the chanels at 90 degrees between
aft and forward ends of the transition) Would that be adequate for
ejection of the parachute? My biggest concern is the reduced strength
of the forward end of the unit.  I don't want to cut so much material
away that it is no longer strong enough to withstand ejection and
recovery.  It is the same heavy duty plastic that LOC N/C's are made

Or should I drill some holes, and if so, how many on each end, and
what diameter?

Or is this just a bad idea?

I want to prevent zippers, and also not have to use recovery wadding.
Thanks for any help!

The transition you are talking about is already hollow except for about a
quarter inch  on the larger diameter. I believe the hollow opening is sized for
a 29mm motor tube.
