I am looking to replace a coupler to connect BT 60 tubes so I can finish my PSII Mammoth. Lost mine...afraid it got trashed. Plenty of people online sell them, but I can't bring myself to spend 10 bucks (shipping is high for a simple order) on one coupler. Anyone have one lying around I can buy?

UMMM are you sure about size? Bt -60 is around 1.5 in diam. and a Mammoth is 2in.

Yep, the PS II kits tend to be built out of non-standard (for Estes) tubing sizes. Mammoth is 2" and the coupler is available for 1.99. Sure you need another $37.99 worth of rockets to avoid the shippinghttp://cdn.rocketryforum.com/images/smilies/3.gif

I've used mailing tube as an outer coupler for this, 2in ID.

If you've got any tube stock larger than 2 inches it is pretty easy to fabricate a coupler.
