The Sander Mill
One of the projects I had in mind when I bought my metal lathe is to produce one of the Sander Mills for pen blanks that is shown on the IAP forum.
I currently sand my blanks after CA finishing on a disk sander and, whilst generally acceptable, there are occasions when I am less than satisfied with the fit to the kit parts.
One only has to be the slightest bit out of square for a gap to be noticed.
So I turned up one of these sander mills and here is the result. The long shaft takes a slimline bushing, other pens will reguire sleeves to be turned for them. The short, fatter, shaft can be put in a cordless drill, a drill chuck on the lathe, a drill press or any other means. I would thing even hand rotating will work.

Will pick up some adhesive backed abrasive paper at the WWS tomorrow and give it a "whirl".

You could make the shaft removable , by threading the mount, then you could use different sized shafts, for the different pen kits. Just make sure you thread in the right direction....
Nice peaice of kit thereI may not have gone where I intended to go, but I think I have ended up where I needed to be.

Looks awesome, BS! Very keen to hear how the trial goes. Don't forget something to clean the glue out with.

Yeah I'm down with that. What I am getting at is part of the commercial pen mills useage is to square the ends off down to the tubes, and to clean the glue out of the tubes with the little fluted end, sorta like a two for one deal

That may be the intention, but it never works. Even the glue that stays in the small gap between the mill flute and the tube is enough to ruin a pen - I found that out the hard way. I manually check with a normal drill bit and scrape it through any bits of glue stuck to the side.

Gra, I have thought of that (what do they say about great minds..........?). There is a problem with that however, the sandpaper disk (19mm OD, 6.3mm ID) has to but up to the shaft, otherwise the sander doesn't sand the blank and the tube. If You then take this shaft out and put in a thicker shaft, you will also have to enlarge ID hole in the disk to fit.
Bit messy IMHO.
It wouldn't even have to be threaded, you could use the standard pen mill approach and use a grub screw, but I think that is one of the failings of the standard pen mill.
On balance a sleeve is quicker and neater, alternatively you could make a dedicated sander mill for each pen kit.

I've found that the first step to removing the glue from the tube is to sand / mill the ends. Glue to glue bond is MUCH stronger than glue to brass bond. So if there's any
glue on the rim, then the inside and outside glues stick together very well.
Once you sand or mill the ends of the tubes, you break this bond and the glue is easier
to remove by pushing up on it through the bottom. I use the metal rod from a disassembly kit.
I think that to use this end sanding tool to clean the inside of the tubes might be
possible by eliminating the shaft that goes in the tube, and making a hole in the disc
with a set screw. This way, tuners can use their own existing pilot shafts from their
pen mill kits. Now that I've turned on the metal lathe, maybe I'll give it a try.
Of course, all I've made so far is a mess, but it's worth a shot..

Nice one Fred great use of the metal lathe. As suggested if you make the spools with a threaded end section then its just a simple matter of have the size spools and screwing them in and out to change size. Just make a lot in the tube for the screwdriver.
I can see no reason these have to be made from metal either a dense timber should also suffice or for that matter an acrylic

All I use to clean out the glue is a spade drill bit.

Sam, see my reply to Gra re the different threaded inserts, you run in to problems with your sandpaper.
You can probably make them from any material, just what their longevity would be with the frequent insertion in to chucks etc I don't know.
Picked up some textile backed abrasive toady from the WWS, together with a very fine velcro type self adhesive base material and will be trying that on the Sander Mill tomorrow, will report back then.
Will also be turning some Corian sleeves for a few kits I picked up from Jim Carroll at the WWS, so time will tell.
