Scotchbrite multi finishing wheels
Today I borrowed a Scotchbrite wheel from Greg. It's about 6" in diameter, and mounted on a half inch shaft.
Set up my trusty old Sher drill in it's cradle, and clamped the whole kit and caboodle on the back yard table. Dragged out the extension lead, and plugged it in.
Bugger, the drill chuck is only 3/8" capacity. All that setting up for nothing.
My question is, have you had any experience with Scotchbrite wheels. I Googled Scotchbrite and came up with this
Scotch-Brite™ Multi-Finishing Wheels [click to enlarge] Produces uniform grain finishes on stainless steel and other metals. Highly conformable and tough enough to finish edges and welds.
Make a Selection Scotch-Brite™ Multi-Finishing Wheel, 6 in x 2 in x 1 in
Highly conformable, soft wheel for producing uniform grain finishes on stainless steel and other metal substrates.
1. Are these wheels expensive, there's no mention on the 3M site.
2. Are these wheels too fine to remove light rust?
3. Who sells them, I'm in Heidelberg.
If the above is not the go, what do you suggest. Be nice to find something that screws onto the standard grinder tapered mandrel, or take the place of the grinding wheel, as above.
Looks like a bush will also be needed if used in lieu od a grinding wheel, the inside dia of the Scotchbrite wheel is 1", and most grinders have a 5/8" or 16mm shaft.
I wish to remove light rust and basically prepare the handwheels off my Arboga mill, for polishing.

Ken cant help with the price etc but why not clamp it in your 3jaw and use the lathe to spin it. At least you will be able to see if it will do what u want.

I got mine from Stuart Minuskin (second last item on this page). I think you can also get them from Kerry the sandpaperman - they aren't on the website but I'm sure he can get them

I think a bloke on Ebay also sells them UBlast is his sellers ID .
I asked once if he has them in 8" he said only 6" .
I'm still tempted to get one or two though.

Ken, there is quite a range of these scotchbrite products, including wheels, belts, pads for 2 inch and 3inch holders that are used freehand in a drill or similar and hand pads.
Try a dedicated abrasives supply like Sumabrite in Oakleigh, or industrial supplies like Blackwoods or North East.
If you don't need to do a lot, try Groomy for used ones, he quite likely has boxes of them about 4-6inch dia from the polishers (various widths, taper mounts). When we were working SteelTrends in Vernon Av and after we moved, about 80% of the Scotch wheels we used come from Groomy's scrap boxes, he was glad to get rid of them.

G'Day Ken,
I used to work at Baxter Healthcare we were made I.V. Solutions onsite including the no-tox vinyl for containing the fliuds.
We purchase larger 200mm dia 3M scotchbrite from Blackwoods or A.E. Bakers and yes they were expensive but lasted sometime in our maintenance workshop.
The unit was a large pedestal mount on a long spindle with plenty of room around the wheel to work the job.
We mainly used it to polish the stainless steel welds plus some aluminium finishing.
Hope that helps.
Cheers, Crowie

Hi Fellas, have just returned from visiting the ex missus. Can't escape without the mandatory couple of glasses of cardboard boxed medicine. Am even good mates with her fella. Life's too short.
So, back to the business in hand. Sounds as though Scotchbrite is the way to go.
Greg, I always find visiting you, a trip down memory lane, and an inspiration, I never know what you will suddenly plonk on the table.
Greg produced this enormous dial gauge produced by a chap in Sydney. I reckon about 4" in diameter. For us oldies with failing eyesight, a god send. The original cardboard box was probably worth more than the price paid.
I won't spoil Greg's post on this, there will be more to come on dial indicators. Be watching.
PS, will pop over Wednesday for a coffee, and bring the camera. You have been warned, I prefer the pink lippie, and the little black number.

scotchbrite wheels are available at all the industrial supply shops.dont run them too fast as they can melt onto the surface of your job.you can get black scotchbrite down to brown i think,and they come with a nylon centre also,(for mounting on tapered spindles).i have used them when polishing my stainless steel spiral staircases and other cosmetic bits and love them.

Hello Ray,
Is there any chance that you could post some snapshots of the finish acheived using that wheel? I haven't progressed past a wire wheel.

Ken,
Given that you are a little bit older than me and your eyesight may be a little worse, I have a nice 3 1/2" diameter Federal dial indicator that you can have if you think that it may be of use. It is graduated in 0.001" and from memory has an inch travel. Let me know if you are interested and, if so, I can post some photos.

Hi Bob,
Not a particularily scientific test, here is a bit of aluminium, the right hand side had a few seconds on the wheel, the left hand side, rough machining, you can still see machining marks on the right hand side when the light is right, if I kept going you could remove the machining marks completely and replace them with fine scratches....
I find it handy for lightly cleaning up burrs and general touch-up type work, and might be ok as a starting point for serious mirror finishing..
Regards
Ray
PS... This is a bit of that gummy aluminium extrusion i referred to in another post.
