Me again...

I've made a few 80mm spindle mounts (only one picture shows finished mount):

The drawing is just an example - if you want a different size or to draw your own that's fine. I have got aluminium in stock to do up to 150mm wide and 1/2" thick, or 5/8" thick and 125mm wide.

If you're interested send me a PM or make me an offer...
