Yesterday I uploaded a Photo Album of the sanding arbors I was making. Today due to the popularity of that I am posting a detailed step by step article of the same project. I'll add the holder I made for it as a special bonus feature at the end too.

Step 1: Tools and Materials

These are the tools I used. If I had a metal lathe I would have used it instead.

Milling machine used as a drill press
Multipurpose Vise
Letter Q twist drill
3/8" X 24 TPI tap
Tap handle
5/8" combination wrench for arbor bolt
3/4" & 7/8" wrenches for T slot hardware
Plunging Wood Router
1/4" spiral up cut router bit
#24 twist drill
3/8" twist drill
9/16" paddle bit
1/4" end mill
45˚  countersink
bench grinder
hack saw
Phillips Screwdriver
6 inch calipers
Combination square
Craft knife
Center Punch
Transfer Punch (see text)
Hole saw (see text)
Hat pin

a piece of Melamine, or MDF large enough to cut (4) 6" diameter circles out of
a small scrap of hardboard (to make the router trammel out of)
an 8D nail for the trammel pin
1/2" OD heavy wall pipe (the pieces I used are about 10" long)
3/8" X 24 TPI bolts about an inch long
2 washers that fit snugly on 3/8" bolts for each arbor made
6" PSA sanding discs assorted grits
80 grit sanding belt

That is about all I can think of now.
<p>OMG... Sorry but you've lost me on this... </p><p>1) How do you cut the circles with the router? Your explanation isn't really clear.</p><p>2) What is a Letter Q bit? I guess everyone except myself knows already, but a brief note might be useful for those who don't know! A bit of research shows that it's 0.332 inch/8,4mm.</p><p>3) Tapping the pipes photos - that looks more like a &quot;spot the difference&quot; competition; please try to take a photo of the subject (using macro mode if you've got it) or at least crop the photos to show the important details.</p><p>Just trying to be helpful, no bad feelings! ;-)</p>
<p>I did not say this was a beginner project suitable for everyone. By the time you have the equipment to tackle a project like this you'll know what a Q bit is then too.</p>
