How sweet is this looking?
Shame I messed it up.
After all the effort to shape it, I realized that I had not left a recess on the back for the strap and if was to add material to make a channel, each cast part gets thicker than they should be as well as heavier.
Even thought I used a special silicone spray designed for polyurethane, it just stuck and would not come off the epoxy master part.
So I decided to make another using the PU this time as it is easier to work when sanding and I had modded the mold to include the recess in the back. It needs a good clean up and then I will make a new mold.
This time I will make the plug in the back first and then used that to seal up the back instead of using clay. I'll end up chopping this mold up and using it as filler for the new one.
I also want to make the part a slight bit bigger than this part is and I will do that by pouring layers of PU over the top rather than sanding first as sanding reduces the size and I need to make sure the new part is the same size as the buckle on the shoe so it fits and covers the the area where they glued the original buckle down.
