Default English Wheel tracking, T coupe trunk

Can anyone explain how to wheel up the top panel on the trunk lid, the section that has reverse curve. Ron covell shows how to briefly, wheel a similiar "tulip" panel but without detail as to tracking patterns in one of hi roadster DVDs that I bought. He real broad

First thing he does is roll the panels into a shallow u shape along the panels length. He then proceeds to wheel length wise this is where I feel he doesn't provide enough detail

This is my newly built wheel and the panel so far. Hope someone will chime in. If this is in the wrong section, please move it moderators

Ryan do you have a picture of the shape you are trying to achieve? That would be help full in knowing where to wheel next.

Try this: drawing two lines, from corner to corner, making a long"X" across the panel.
Now make a long oval in the center.
Your wheeling pattern is to not wheel in the oval or on the diagonals going to the corners, but to wheel the edges marked by the triangles fading into the oval - so that they turn down, and allow the center to stay up.

Delicate job for a wheel.

Video can be hard to teach subtle things with. I know I have spent considerable time teaching surface response using a polished surface with a contrast grid overlaid as an indicator of surface changes. Easier to skip over the subtle stuff because of its difficulty clarifying.

You could always push it gently to shape with mallet and sandbag then just wash it out on the wheel.

Will that oval be drawn tangent to all edges of my panel?

oh no, just around the center - say 1.5 X 10. This will the the area that receives no stretching. The area is not well-defined but will be as you see what the shape does that you put in from here.

If you turn this upside down, it is just another saddle. I made one of these for a 31 chevy coupe several years ago. It is fun to watch it take shape, but you must pay attention because it goes quick. The only problem I had was I needed to go over it about three times to get it to lay without any tension. Just do what Kent said and don't stretch the center.

Which oval is correct, the one perpendicular to the panels length or..

I wheeled the short panel prior by wheeling outside the center box covering the outer third of the panel more then the areas that are closer to the center box. Tracking direction was with the length


I'm still uncertain as to what area is being wheeled, I understand to not wheel the oval . am I wheeling all surfaces but the oval, with more emphasis on the left and right sides of the panel ?

Your long oval is correct.
Wheel the two long sections edge-in.
Then the two shorts, but they go further in. Edge - in.

So your stretch is in a taper, thinnest at the edge tapering to zero near the oval.
