    Default Radius dish?

    I just built a 15' radius dish, I'm going to put sand paper in it so I can sand the sides for the back. What grit sand paper should I use?

    Thanks!

    Do you use self adhesive backed or 3m spray to attach the sandpaper?

    I use adhesive spray...it's something I use in the shop quite a bit and wouldn't want to be without.

    I got one of SMD's sanding discs. Hideously expensive as usual, but I use it a lot. Grit is 50 by the way.

    I used to use 80 grit..but now I use 60 grit much faster and gives a good glue joint..my radius dish is rectangular shape with a compound radius 5ft X 10 ft. I find that heavy duty 6 inch cloth backed sanding belts the best.

    I go down to my local rent-a-tool place that rents rotary floor sanders for doing hardwood floors. They use 17" disks in a variety of grits. These are really tough (made for power sanding hardwood floors) and pretty inexpensive (only a couple of dollars each). Stick them on with spray adhesive and they last just about forever unless you catch an edge and put a tear in the paper.
