Anyone have a magneto speed mount file?
I’m looking at making a DIY Magnetospeed Chrono mount.
A couple questions about measurements, and its DIY practicality:
1. How far in front of your ARCA rail would it need to mount?
2. Printing a bracket to mount to an ARCA clamp is simple enough. it will require a 2 bolt ARCA clamp. Those run $60-75. Or you can mod a $15 Amazon Arca clamp like the one I posted above. is that mod practical for most folks?
3. To make the mount allow the bayonet to be position adjustable relative to the barrel, it will need to have 4 rods , each of which is 2-3” of aluminum, and the end of each rod will need to be drilled and tapped for a screw to mount it to its receiver block. That’s not too complicated a bit of machining with a drill press and some type of vertical fixture, but it has to be precisely parallel and centered in each of the 4 rods. If not, it just won’t work. How practical is that for most folks?
I think I’ll make one, just to work through the process, but I expect it will cost not too much less than just buying the MK Machining mount. I figure at the cheapest, a 16” long bayonet mount will run me $80 in materials, and a few hours work. if you can’t modify the Arca clamp, or if you have to pay someone to make the adjustment rods, it’s likely to be $100+, and not be as stable or durable as the machined version they make.
It will be a fun project though.
