I am fortunate to have access to a machine shop and some good people that are actually machinists. So I took a crack at making some rudimentary Dynafit Speed Radical toe piece to Voile Touring bracket adapters. They ended up working but aren't pretty or light! It's more of a first revision and practicing my basic metal shop skills than anything.
I used the toe piece itself and the Voile touring bracket as my templates. I roughly lined up the pivot points and used transfer punches to mark the holes to drill starting with a rectangular 1/4" thick plate of 6061 Aluminum. Unfortunately the countersunk holes of the toe piece and the sheet metal touring bracket don't support a transfer punch well and I'm not too skilled at lining things up by eye. This resulted in my stride being crooked with respect to the board.
As you can see it's actually pretty bad!
Once I had the holes drilled and things were going to work. I scribed the rough outline of the toe piece and band sawed them out. I also milled a slot in the middle and removed some additional material by drilling a couple holes.
Not too bad doing nearly all operations by hand!
I then made a climbing wire adapter to move the climbing wire to the heel of the boot. This was much easier since all holes only need to (roughly ) be along the same line. This was done by just using the climbing wire plate as a template and transfer punches. Then I put the boot in the toe piece and marked where I wanted it to hit and drilling those holes. I will cut a lot more material to make them lighter next chance I get as they are currently just big hunks of aluminum with some holes in them.
It will get the job done for a bit!
In the end it was a fun little project. However I drew a print that locates the holes and all other features. I will use a vertical milling machine (Bridgeport Series I) to do all the operations so I don't have anything crooked or weird going on. I'd also be able to take down the material thickness to make it lighter.
That said, in the end I think installing Quiver Killers would be a really good option for part time Dynafit hard booters like myself.
