Ordered case liners for an experimental motor, but the seal disk for my Dr. Rocket motor wont fit at all, suggestions?
But it(seal disc) does fit inside the motor case? The seal disc does not go IN the liner, it sits at the TOP of the liner..
Unfortunately, since I am currently under 18, and will not be 18 until about a week before my permit flights and thus my first experimental flight the next day, I am unable to order from RCS... Under recommendation of other in the experimental motor field, I am using a fender washer for the fiber washer by the nozzle as a subsititute for the fiber washer. Could two fender washers with High-Temperature RTV sealant between the liner and the casing, and between the wasters and the liner, with the liner firmly pressed against the washers work?
Seal disk is aluminum, fits in casing not in liner. And thanks will seek assistance, as I have been for the five years I have been doing experimental rocketry. I am new to using reloadable casings in experimental rocketry, which is why I am here asking questions. thanks for advising me not to use metal washers.
If you look at the motor assembly drawing pdf's on Aerotech's website of the I49N and I59WN, they show the endburner-style closure. It has no provision for a smoke grain, and I have no clue where you might obtain one. And I don't think that it would make the seal disk unnecessary, either. Maybe use two fiber washers or machine your own seal disk to fit the liners.
Did I miss something with this thread? I thought you have to be level 2 and a member of Tripoli to be legal for experimental rocketry?
