abs is very easy to weld togeather, if you had two bezels it wouldn't be very difficult to do what you need to do....

I've followed your mould job, & I always thought that if I was going to go through all the work to create a new part cast from a mould, that I would have done the oposite of what you did.....

instead of casting the stock part to modify after.... I would have modified the original to what you needed it to be, then make a mold of that...... the part that comes out of the mold is the finished new product...... & duplicatable if the mold holds up..... I think you could weld a bezel togeather easily enough really & eliminate the mold all togeather, abs is actually easy to work with... if you need a hand with the bezel pm me....
