G'day all.
Earl enquired about how I sand the inside of my toy car windows, i
n this thread.
I started to explain, but a fear it was turning into a novel so, as they say, a picture paints a thousand words.
1st I drill the holes with a 1" forstner bit, just deep enough for the point to protrude from the bottom, flip the piece over and drill out the remaining piece.
Then I route the inside with a 1/4" round over bit.
Next I sand the hole with a 1" mandrel wrapped with 80g paper.
I then use a sanding jig I have made (a very basic flap sander).
It is a 3/8" bolt with the head cut of and slot cut down to about 1" from the end.
I place a piece of 180g paper in this about 3" wide by 8" long.
The pics will explain I hope
Any Questions, just fire away.
BTW, The pics with the paper in the hole were taken with the machine spinning, the camera froze them.
