Default Boot mold

Thought some of you wonderful people() might like to follow along with the design and manufacture of the replacement boot plastic injection mold?

The first picture is the basic CAD rendering of what will become the mold cavity (love my 32" monitor!).
The second picture is of the raw 7075 aluminum blocks that will eventually become the entire mold.
The third picture is the first squaring cut on the first block.

The finished mold will be approx. 7"X8"X8". The goal is to have molded parts in hand for CoachWorx of which I stopped by today and visited with Jim Nichols and Rick Mays. They are looking forward to the rally

My wife and I had a nice dinner tonight with Ron and Dorinda Rueckwald as well as Dorinda's dad Tom and sweet girlfriend Donna

Can you explain how the sides will fasten together?
I can't tell by looking at the rendering.

The rendering is just a partial drawing. It is of the outside wall of the boot body. The male/female interlocking lip detail is on a separate 2D drawing on another page. This is enough detail for me to 3D CNC the cavity finished with a 5/16" carbide ball end mill staying within this rendering. More details to come later, promise

Looks a little over-engineered... hehehe, ducking for cover! Seriously though, nice work Ryan! So I take it that the boot is in two halves, an upper and a lower half such that the boot pivots in the center, and removal of the ball joint is required to install the boot? Ryan, what material are you using? (I can keep a secret ).

This new 2 piece boot is for the lower (larger) ball joint only. It can be installed without removing the ball joint which is a huge undertaking otherwise

Material... jury is still out on that. The big issue, material wise, is coming up with a flexible material that can hold up to the heat generated by the disk brakes which I believe is the main culprit for boot failure to begin with? I would like to mold samples in Urethane, PVC, TPE/Santoprene and Engage. Maybe Chuck Milsap can provide some suggestions?

I believe a heat shield should be put into place as has been alluded to on the other thread?

Thanks for your effort Ryan. The design looks good. If the samples fit, we can always try different materials.
