That turned really well Bob. It was good to meet you at Dan's and the donut dolly is a hit!
Cheers, Richard

Brent, I started with triangle shaped pieces. The first one was made on the wheel and was almost all stretch with just a little Lancaster work along the edges to tighten the shape up. The piece was curling up like a dry orange peel when Ed Thomas came along and suggested I change the arrangement by flattening the piece out by bending the edges out by hand. This advice helped tremendously. I was able to continue wheeling the piece by rearranging the shape until it fit the buck. The second piece was done in about 2 or 3 hours. I used a bag and a heavy blocking hammer made from a 2" trailer hitch ball. Then I wheeled the lumps out and shrunk the edges with thumbnail dies.
I can't emphasize this enough. When you attend a meet, take a project along to work on. There will be people there who know more than you about shaping sheet metal. In my case, a lot more. When you encounter a problem there will be good advice available to help you. It's a great way to learn. |

great explanation. that 2" ball sounds like quite the hammer!! any info on the trimming and fitting? as you cut did you have to go back to shrinking the edges or did trimming off the edges not effect it with the toe nail dies like it does with lancasters?

I shaped it until it fit the buck with extra material at the edges. There was a center line marked on the buck. I transfered that line to the metal halves and trimmed off the excess along the edges.

I'm back to work on this cyclecar project. The cowl was roughed out a couple of weeks ago then this weekend I trimmed the lower corners and rolled the top over. There are a lot of hours in this piece, mostly learning, so I wanted to take this last step carefully. I made some simple tooling and a test piece. It started well then as fatigue set in ( I'm 67) things started to go hay wire. So I adapted the tooling to my Helve hammer and had better luck. The last picture is a test piece which I screwed up pretty bad rolling the edge by hand. I was able to fix it with the Helve. Also, and a bit off topic, the area inside the red circle was a bulge out that needed to be a reverse curve. I was able to shrink it back and extend the reverse shape into the curved area above it by heat shrinking the area with a torch and a heavy curved steel slapper. It worked peachy keen.

Bob,
Looks to me as though you made real good use of your thwakka-whapper-atter tools to get your shape so true.

Nice to see you getting it done! It's going to be a real looker too. You have some real talent.

A little more work on this cyclecar project. I've made and installed the doors and the new radiator shell is about 90% done. The last 10% of course takes at least 50% of the total time. Still need to devise a latching system for the doors and a way to attach the radiator shell, and a million other details.
