Do you have a plan for the bias cut on the forward end of a new BT5? I may have an idea.

Amen to that.Thank figure of speech for spent motors. They have 1001 uses.
Um, cut it with a knife? I imagine that with the motor casings supporting it, the cut will be very quick and easy. What did you have in mind?Do you have a plan for the bias cut on the forward end of a new BT5? I may have an idea.
In theory it seems as if it would not be a straight cut. In practice, the cuts come out pretty straight using my cutting guide. I don't know were the truth lies. To figure it out exactly would require some CAD work.The forward end mates to the transition, so that is not a pure straight chamfer type cut you would perform with a saw. It would be a curved cut, right?
Things are going to slow down now, as I wait for an opportunity to glue on the warp tubes. I expect it to be a challenging process to get them on correctly..
Nah, it's totally flexible.If the tubes swelled with the CWF larger than the basswood guides, will the finish “crack” if you try to constrict them back to the diameter size of the guides?
I think it would be hard to sand them in-place. My real mistake was cutting the pieces before CWF. I was so eager to cut the new pieces that I didn't realize I had forgotten the CWF until afterwards. If CWF first, then cut, should be no problem.For future builds, given these were snug on the basswood guides in post 66, question whether might be reasonable to glue the tubes in place first and then CWF them?
Great question, but I admit I never think of doing it. Like you, I usually just wonder about it afterward.Have you ever weighed parts before gluing, then after? I never really thought about it until my Lifting Rocket. The actual as built weights vs Open Rocket weights had me wondering where's the weight difference?
True, although much (most?) of it is water weight, which evaporates off. That actually points to an easy experiment: what percentage of the weight of TBII is water? Results to come...I had a Capt. Obvious moment, shortly thereafter when I picked up the bottle of TBII... that sucker is heavy.

"We're going to crash it into a rock at full speed and see what happens!"
When I get a chance, I will.Throw on a layer of quick and thick and report back?
Darn tootin'.(Lol, that's leftover from IRIS prototyping)
The Rocket N00b did paint weight tests in the past, and someone around here tested the weight of fillers.Fill, sand, prime, sand, and paint, then report back.
You need a new custom material for each fin thickness, although I admit I entered a papered 1/8" balsa and then use it for 3/32" as well because it's pretty close.So how do you add papered balsa as an option in OR? I think that was a contributor to the Defender coming out heavier than expected. Chances are that if I am using balsa for fins, they will be papered. For example, the two stage I am getting ready to start on will have Avery papered 1/8th inch balsa fins.
Yeppers.BTW, the Plasma Dart is coming along great. Is that electrical tape wrapped around the motor mount tube?
