Rotating monitor construction *Project finished*
DaOld Man:
Today i picked up a skateboard bearing set at Toys R us for around 12 US bucks.
It is 8 bearings and 4 sleeves. Probably wont use the sleeves.
danny_galaga:
bearings worked well in my situation (",)

I've been in the garage since Friday since I had off. The roller skate wheel bearing trick is where it's at! I've got updates coming, but I want to ensure everything works before posting.. stay tuned ;)

I can't wait to take a look at what you've done!

Ok, I made a rig to allow my router to cut out the circles I need for my rotating project.
First I laid out my dimensions.
I marked the holes for the lazy susan bearing, and the 4 holes for the monitor to bolt to. And of course a center hole.
I stacked the marked board on top of another.
I then drilled a 1/4" hole in the center through both boards. I then ran a 1/4" carriage bolt through both.
Counter sunk a hole in top board for 1/4" nut.
I also drilled the holes for the lazy susan bearing through both, installed 4 screws in the holes to fasten the two boards together. Counter sunk the screws in the top board.
heres another shot of the lazy susan bearing. The nail marks one of the monitor mounting spots.
Next a got a piece of mdf wide enough to mount the router to.
It was actually about 1-1/2" wider than the base of the router.
I drilled a 1/4" hole in the center, then stuck the router bit through the hole.
Next I marked the base of the router.
Next I routed out about 1/4" so the router can set down into the wood. base is pretty snug.
I then mounted two 3/4" conduit clamps to hold the base of the router. The 1/4" bolts for the clamps are counter sunk on the other side of the wood.
I then bored out the router bit hole to 1-1/4". This gives more room for dust to get out.
The router clamped to the wood.
Next I flipped the rig over and marked the location of the inside edge of the router bit.
This will give me a reference to measure my circle's radius.
Notice how the conduit clamp bolts are counter sunk.
Next I measured from the inside side of the router bit to get my mark for the pivot hole.
My circle needs to be 23" diameter, so I measured 11.5" radius.
Ok, rig is mounted to the board to be cut.
It pivots good. Im happy.
First cut is finished. I went about a 1/4" deep first. Vacuumed the slot and allowed router bit to cool.
Three passes later and Im done with my first circle. Measures exactly 23" diameter.
Now, first cut on the bottom piece.
This circle will be in the back of the monitor, and the lazy susan bearing will mount to it.
The scrap I had wasnt enough to make two complete pieces. This circle will have a flat spot. I may not be able to make it work, if not, I will have to buy a new sheet of mdf and cut another one.
Here are both pieces finished. Mickey seems pleased.
Next: Got to cut out the monitor hole in the first piece.
I like the circle cutting jig. Its got a special place on the wall of my shed. i know I will be using it again.
Edited for spelling and grammar.
