I start the end and curve the upper part of the tub so its close and tap the crimp closed right at the end... its much easier to have 2 people doing this job... once its started then tap the metal into the receiver groove good and about ever 6" to 10" tap the receiver closed then once its all in go back and tap the whole flange closed using a wooden block and hammer Also I use a rope to hold the radius close(tied around the tub on the radius... about 2" from the crimp joint)

I will try the rope thing. This is the problem I am having. Getting it started the key needs to be lined up 10"s away to let the rest fit in. If I could get the flat stock with the S bent to have the same rad as the tub it would just tap in. I will try the rope or ratchet strap. Cheers Don.

Usually you can see a notch at each end of the seams male and female, line those up and start running the seam together. I'm a sheet metal worker for the union, spent some time in the fab shop, a duct 90* elbow is basically the same as a wheel tub.

It looks like a double bend or S shape. The rad of the tub is just a 90* roll. It needs to fit into one end of the S then the end of the S to be tapped over to hold it in. Cheers Don.
