I planned to bash the Loc Vyper III kit I have to use a baffling system; however, the bulkhead assembly I ordered from Rocketmotion never arrived (ordered over a month ago, but R.M. almost certainly didn't have any in stock, and had to special order them themselves).
Therefore, I have decided to turn my own bulkheads instead. I bought some 3/16" aircraft plywood from the local hobby shop, and I have a couple of 2.6" coupling tubes that I've had sitting around for awhile that I can use.
The only problem with these coupling tubes is they are PML, not Loc. They fit in the Loc body tube, but they are a tad...loose. This is no doubt due to slight differences in the diameter of each company's products. The fit is close enough, however, that I think I can get a snug fit by building up a thin layer of epoxy on the coupler tube. I like the PML phenolic better, anyway.
These coupler tubes are 4.5" inches long...I was planning to cut one in half to use. However, these tubes are long enough to be used as a mini-payload bay as they currently are...at least for a simple transbeep I would think. I'm thinking now of possibly using the entire length of coupler and cutting bulkplates for both end, with a 38mm tube inside the coupler to hold a future altimeter. Meanwhile, both bulkplates with have eight 3/8" holes drilled around the perimeter, for the ejection charges.
THE WORK BEGINS
=========================
I cut one bulkplate today; however, I measured wrong somehow. I made a pencil mark on the plywood on the ==inside== of coupler tube and set the bit diameter down to that mark...however, the resulting piece I cut turned out a little too small. Tomarrow I will make a mark around the ==outside== of the coupler tube, and turn a bulkplate of that diameter. This should make a plate that is slightly too large, but I can always sand it down. Too large is better than too small.
When I turn the next bulkplate, I post pictures as well
