Hi Boobee
Here is the bead roller that Bob made. You can buy them for not a lot of money but it is more fun to make it and then you can have exactly what you want. It would look better with a CMP wooden wheel.
The second photo is an upcoming project. Thanks to Brian Gough for lending me the left fuel tank for the C15TA. I am missing this one so while I have a sample around we will get it measured up.
The last photo is Bob playing around with the bead roller to duplicate the side of the fuel tank.
Cheers,
Barry
