A couple more renders on the aperture project

After a few prototypes, I've discovered that a few modifications were required.  The bolt head is now shaped for a pan head bolt (much easier to find) and slides in from the back so that the archer's view is smooth and symmetrical.  A few parts were thickened to add strength, and a few places were trimmed to avoid thin wall problems.  Also, the third variant, the non-glass o-ring only aperture, was added.  All will be available in right hand or left hand.

Coming soon - recurve apertures you can build

I've been testing/prototyping a recurve aperture which I plan to make available to anyone who wants to put one together.  I'm not going to be selling these things, but rather I'll make the model available for order from a 3D printing company, and then you'd acquire a bolt, a nut, o-rings, and glass if desired.  So far I'm thinking two sizes would be good: one that accepts a 15mm glass window (about 5/8" O.D.) and one that accepts a 12.5mm glass window (around 1/2" O.D.)  Naturally, you'd only use the glass if you want to use a dot or drill it for a fiber.  Otherwise you would be able to just use o-rings to vary the size of the aperture opening you look through.

Here's a rendering:

Stay tuned ... should be ready soon!
