I am watching these out of order so it is starting to make perfect sense now. Thanks for sharing, i am learning allot!

Here's the playlist in sequential order if your curious. I know it confusing that each episode isn't numbered. Feel free to skip around.

That was cool. The hammer form worked pretty well and was a good solution.

Bruce Wayne Thanks Bruce! It's a bit unconventional, but a good example of "If there's a will there's a way". Thanks for watching.

I thought normally when wooden bucks are used like this, they're just used as a template to hold the metal piece up to, to see how well it fits. The actual metal forming I thought is usually done with a hammer, anvil, dolly, wheel, and the usual metal forming tools, and they then keep fitting the part up to the buck until the shapes match. That would make sense, as I think the wood would deform pretty fast after being hammered on. Nice work though, your channel rocks. I've got a 912e that I'm starting to think how to swap a normally aspirated Subaru flat-4 into to, and I think I'm going to with a front mounted radiator like a Carera RSR, and I'll make the radiator relief into the trunk area for air flow.

Hi Andy, Yes you are right, this is not the most conventional way of metalshaping, although it is done. I'm not claiming to be the pioneer here. Hammer bucks are what I think you are referring to (those dinosaur skeleton looking things). They are used to check the shape of larger panels. Hammerforms are used to hammer or press metal into. Sometimes they are made of wood, or MDF in my case. I was a little surprised too that the wood did not dent as I hammered it. I think it helps that I used a fairly wimpy nylon hammer and when the sound changed I stopped. I didn't try to make it perfect in the hammerform because I knew I would finish it on the English wheel. Some make hammerforms by making a fiberglass mold off an original part instead of the template/CNC approach I did. When there is a will there is a way...that is what hotrodding is all about.

Nice work

[@GarageTimeAutoResto]

I appreciate it!

[@AndySomogyi]

What software did you use to design the forms, Autodesk Inventor or SolidWorks?

[@GarageTimeAutoResto]

Solidworks, 20 minutes tops. I imported the scanned templates as a .jpg and drew over those image lines with curves on four different planes.

@@GarageTimeAutoResto Interesting, do you still have the .prt/step file that you're willing to share? Would be fun to try to modify for different arch profiles. Cheers!
