Expander Tubes

Hi everyone!

I have contacted a manufacturer in Texas who is willing to make J3 expander tubes! I will have to provide the specs and give him my old tube to reverse engineer. This is a large aerospace manufacturer who will have to get orders for at least 100 tubes before they can commit to manufacture.

I'll take 2 or 3 and would like to know if anyone else would be interested in buying some? I don't want to do a conversion and want to keep my old hydraulic brakes.

Please let me know if you want an expander tube and how to contact you. I hope this is possible because I just joined today. Thanks!

P.S. If anyone out there has a drawing of the expander tube (with measurements) please provide a copy. I have the original patent, #2,256,431 from 1941 but it does not have the specs, only concept.

Al, I would be interested in your J3 expander tubes if they are serviceable. How much would you want for them? GWS

Here is a picture of what I have for the Cub. I am going to sell my Cub so I won't need all these parts. Let me know what you are interested in.

Just purchased ABI 6" wheels and brakes for my Clipper. Will have wheels, brakes and new old stock tires for sale shortly. condition of brakes are unknown, they haven't been used since 1960.

The tires are probably ok. Maybe the tubes if inflated and protected. All expander tubes are that old, and a lot of them still work.

No, there are small parts in the bags and one of the wheel covers in a bag
