I would like to organize a joint part order to split shipping costs. I was thinking Balsa Machining Service.
www.balsamachining.com/# . Go under "Kit & Building Supplies" tab and there is a "Low Power Tubes and Couplers" subtab.
Cutoff would be 1 week from today. Email/PM me what you want to order by 7/1 and I will place it by 7/2. I will bring to July launch.
