Note: We're currently trying to outsource quick release levers -- until we do, we won't be able to offer these kits. Stay tuned!
Many of you have wanted to build the Quick Release Indicator Clamp, but have had a bit of trouble finding a suitable lever-bolt, like the one I got from a used bicycle wheel skewer.
While trying to source a unit that would be easy for everyone to find, I came across this Q-R bolt and lever assembly made by GT Bicycles, for seat-post
clamps. (A very high-stress application.)
I guess the bike this lever was used on was not going to be continued in their model line, and there was a small surplus of these lever bolts.
In a fit of exuberance, we bought them all.
We took the units, re-drew the plans to take advantage of the nice features of the bolt, and are now able to offer a complete parts and plans kit for the project for just $9.95 (plus s/h) while supplies last.
Sadly, I won't be able to get any more of these Q-R bolts when these are gone, so unless another windfall of quick-release levers falls into my lap, this is a one-time project offering.
The kit consists of the Q-R bolt, one 4x40 socket-head cap screw, a piece of 1.00"x .825" aluminum stock, (which is big enough to supply more than enough material to ensure nice, square and accurate finished parts,) and two pages of drawings and notations.
(Note: Material specs may change -- due to availability --without notice, but will always be appropriate for completion of this kit.)
This GT Quick-release lever is a really nice unit!
It uses a ball-and-socket configuration to cut down on friction, allowing a lot of clamping force without much effort, and the slick black finish is extremely durable.
I believe it's really thick powder coating, although it could be some sort of hard-wearing enamel. Whatever it is, it should wear very well.
The lever comes with a hard plastic socket washer, a cup for the washer, and a straight-knurled finger-nut also made from aluminum with the same tough finish.
(Perhaps it's hard-anodized??)
The new plans not only feature a thinner jaw for easier installation / removal from the lathe, but also take advantage of the durable socket washer, countersinking it into the surface of the clamp body to make a nice, recessed lever mount that is practically frictionless to operate.
Other than that, it's basically the same, easy-to-make clamp design, with no compound curves or advanced skills needed. This is a novice-level project.
It's not only fun to build, but will be an extremely useful attachement for your mini lathe, one you'll use for years and years to come.
And, of course, our free plans are still available for those of you who either have a Q-R lever bolt laying about, or simply want to use the clamp with a SHCS
to close the jaw.
