Question for experienced launch tower users.
I'm looking at building* a range of low-cost, non-adjustable towers for LPR rockets. BT-20 and BT-50 will be first, but I intend to cover a range from BT-5 to LT-125, including a lot of oddball sizes in between, and may go as large as BT-60 with the system. Yes, I really hate launch lugs.
How much diametral/radial clearance around the airframe are most people using? Are we talking 0.010 or more like 0.040 inch? A few wraps of masking tape? How many layers? Does this scale by airframe diameter?
*To be clear, this is for my own use, not contemplating a commercial product. In fact, it's quite the opposite. I'm looking at <<$5 of materials per size with quick, easy construction.
