Odd Diameter Tubes

[bguffer]

Composite Warehouse (soon to be part of Wildman Rocketry) produces odd sized fiberglass tubes:
3.5", 4.5", 6.5", etc.

Useful for building mid to high power scale rockets.

For example, 4.5" tube could be used for 1/72nd model of SLS rocket's fuel tank.

Yes. We are all really happy to hear that composite Warehouse is going to be part of Wildman now because composite warehouse sometimes did not fufill orders. It is going to be great to finally get ahold of those odd-sized tubes.

May be possible to use some motor insulators for undersized tubes:

full length coupler tubes could be used for undersized tubes

Another method for scale rockets which have foamed airframes (shuttle fuel tank, SLS, Delta IV Heavy) is to glue foam around stuffer tube, then form/sand foam to desired body tube diameter. Provides scale texture as well. Time consuming though. Centering rings, cut out via plunge router, can be used as guide for forming/sanding foam.

SLS in attached picture has portions formed from foam (the shuttle doesn't, but could).

Looks amazing!
