I'm not sure about the materials cost. I go to the local scrap yard a couple of times a year and pick up odd pieces of metal as well as various size rod. Maybe a couple of dollars for these particular pieces and the bolts, including a couple of mounting rod prototypes that didn't work out. It took about three hours to make from start to finish, including perfecting the design and some brief trials. I like doing this kind of thing so the time isn't an expense anyway.
I think a Gajate is now around $89, at least for the original model. They have a revamped model that isn't quite so ginormous and that goes for around half that.
If you have a vise, hacksaw, tape measure, large pliers, propane torch and a file (just about every garage does), you could be doing some basic stuff like this, especially simple percussion mounts. Music shops sell chrome 3/8" rod but it's very expensive. You could get hot-rolled rod at the hardware store for much less and, with the tools above, you could bend it to your custom specs. If you add in a cheap $10 tap and die set from Slave Harbor Tools (www.harborfreight.com
) you will be able to make an exponentially greater variety of mounts. If you like puttering and making things, this is just plain fun, as you know from the clever auxiliary hihat mount you came up with
My next post will be a simple percussion mount requiring only basic tools.
