Got one of those spinny sander things

>Hi Carole,

If you don't mind my asking, which sandy spinny thing did you get? :) I've looked at the Sorby (don't really know if there are others, but there are bound to be) and the only real reason I didn't "pull the trigger" and get one is that I worry about having to continually buy speciality papers for it. As it is now, I just buy the bargain 20 lb box from Kilingspore and that keeps me going for a year or so. In fact, I've only had to buy two of those boxes, been turning for 3 years this month (time flies) and I still have gobs of paper from the two boxes.

Anyway, I'm just curious about your new tool, how much you like it, availability of papers, etc.

Thanks,

Mike

Al Crandall's spinny sander thing solution.

Rod Peterson -- Ormond Beach

>Al told me about this at the End-O-Pond party at Ray Thompson's place in Indy a couple of years ago. In general terms, get a hole saw mandrel and a hole saw. Take the drill bit out of the mandrel. Grind the teeth off the hole saw. Grind a sharp edge all the way around the circumference of the de-toothed saw. Chuck in drill press. Begin cutting sanding circles out of H&L sanding disks.

As soon as I got home, I bought one of the spinny sander things (and I, too, am assuming we're talking about the Sorby) and also bought a mandrel and 2 1/8" (to net 2" disks) hole saw and ground it down. Then, proud as anything, I emailed Al to tell me of my triumph. Here is what he wrote back, which will fill in some information for you:

Good afternoon, Rod. I wish you had purchased a 2" hole saw so that this reply could have been shorter. If you use 2" diameter you can get four discs cut from a 5" disc with all holes tangent to the outer diameter and .121" between each 2" hole. All figures are given from the mathematically perfect world in which I and my anal buddies live. If you use 2 1/8" diameter, you will get only three discs from a 5" disc unless you accept bites out of the edge of your finished discs.

Your other option, which is the way I would go since you haven't bought your disc material yet, is to buy 6" diameter discs from which you can get five of your finished 2 1/8" diameters. I have used eight hole, 5" discs and spaced my cuts so that every piece had two holes in it, because I already had them on hand. But when I resupplied, I bought no hole discs. This is the route I suggest. The last two times I bought, I went to ebay and bought from a supplier named Barbkat. She ships promptly and has prices I doubt you will beat locally. Totally trustworthy. Just do a search for 5" hook-and-loop or 6" hook-and-loop. She will probably pop up among the listees.

My preference of grits is 80, 150, 240, 320, 400. If I ever find 600 in hook-and-loop, I will add it also. Right now all 600 is done by hand with folded sheet material. Bill Grumbine had never seen an inertia sander in use before mine, and suggested mineral oil for the lube of the shaft since it wouldn't affect the oil finishes which I like on my work. Still, the off spray from the shaft lube will be a dirty black gunk which might stain the work, and care should be taken to avoid this.

That's all for now. Happy sanding.

Hope this helps in your quest.

Rod

>Mike, I got one that fits in my drill. It was a kit with firm, medium and soft holders and a bunch of the wavy edge discs. Can't remember where I got it...Highland Hardware I think.

>I referred to this setup recently in response to a thread about passive sanders, and second very strongly the disks Steve Worcester sells. I have gotten an enormous amount of sanding done with my initial shipment from Steve. I am almost ready to re-order, since the stash is getting low, but give me the Vic Wood sander, coupled with Steve's disks, and I'm truly a happy man. Give them both a try, practice with the sander, and you will improve your ultimate finish BIG time! I keep telling my students and attendees at demos, polish the wood first, then add the finish to seal in the polish.

>I use the Sorby original but it's no big deal. Woodcraft sells a copy for less and that should do the job. I don't know about Steve's paper but would like to try it. I have used the green paper fron Packard nad found it to be very good. I have since found and Israeli company, Gamal [translation - camel], that makes disks from some very nice blue ones that come from a Swiss company and are at least as good as the green. By good I mean that they can be cleaned and re-used often and don't tear. Worst on the list is CS-USA's Artisan. They might cost less but can really only be used once or twice and then dumped.

>If you are in to making your own disks try Industrial Abrasives. They sell all grades of H&L in 1meter by 1 meter sheets. Good stuff and runs less than $20 as I remember.

>Carole, our club buys from Industrial abrasives and we get 400 and 600 in 3 and 4" disks.

There is an article here (Wood Central) about cutting your sand paper. Mentions buying the large sheets and cutting it on a band saw. You end up with squares.

I am curious about the hole saw idea mentioned above. Wonder if you could cut 3" disks down to 2" after the edge wears? Does it matter? would it work just as well if you did not cut it down? It would make it tough to get into tight places if the disk were overused.

How do you hold the sand paper as you cut it? Do you cut from the back or the front? What do you cut against? How fast does it dull the cutter?

>I should have spent the extra cash and got the original. I bought the knock off at Woodcraft and the bearings went bad in short order. Spinny thing no spin no more! Sometimes you get what you pay for.I tried to get bearings to fit it and they cost more than the whole sander.

Carol, did you use a chuck

Wayne Cooper Charlotte NC

>Carol

Did you use a chuck turning that nice bowl? I got my Jet Mini about the same time that you did, but you are WAY ahead of me on turning. You always seem to ask the right questions ahead of me. I need a chuck and I know you research everything very well. If you are using a chuck what kind did you come up with? Thanks Wayne Cooper Charlotte

Re: I wrote that email ages ago.

Al Crandall --NE of Indy--

>I'm surprised Rod still has it. The source on ebay has changed suppliers and now sells 50 discs for what she used to sell 100 for. I haven't used her new stuff, but at that price it is getting up near the cost of discs cut from Industrial Abrasives sheets. I may change suppliers.

My process for cutting the 2" discs was to hold the 5" disc grit side down on a sacrificial anvil (scrap of oak board) with my left hand and apply pressure on it with the hole saw while the press is turned off. I have a foot switch to turn on the drill press, and a quick double tap on it with my toe would be enough to cut the disc. One to two hundred 2" discs could be cut with one sharpening if using the finer grits. On the coarse grits, about 50 would dull the hole saw. I always sharpened the inside of the saw with a mounted wheel in a die grinder so that the chamfer would cause the disc to self-eject most of the time. Sharpening the outside of the saw would be quicker because you could do it on the bench grinder, but I wonder if the discs would pack up inside the saw and be hard to eject.

Most recently I have been just cutting the 5" discs into quarters with a box knife. When mounted, the three corners hanging outside the perimeter of the mandrel act somewhat like the expensive "wave" discs and no abrasive is wasted. As for the 3" disc getting cut down to 2", if the abrasive is worn more than 1/2" inside the rim I think that a better use would be to save discs for hand sanding using the center. Use sandpaper like someone else was paying for it.

>Carol,

I too recommend the Industrial Abrasives Sandpaper. You can get Hook and Loop paper in grits from 60 to 600.

$16 for a 36" by 39" sheet of any grit.

Using a worn out blade on your BS, or using a box cutter and a straight edge, you anc cut 300 disks in the time you can cut it with the disk cutter on a drill press, etc.

m

Leaving the square works just fine, works like the wavey edge disks. If you really need a round disk for something, 10 seconds with a pair of scissors....

Consider that you can buy a sheet of each -60, 100, 150, 220, 320, 400, & 600 grits for $112 plus shipping and make over 2200 2 1/2" disks.

By comparison, if you have to buy 50 "gold" wavy disks for $12, you would pay $528 for the 2200 disks.

>Hi Carol

Royce sales in canada, also found at www.sandpaper.ca.

They have 1", 2", 3" discs from 40 grit to 3000 (that's right 3 thousand). The prices are the good, service is great, and the paper is execlent quality.

The price works out to $0.14 per disc in all but 40 and 60 grit where it's $0.17 per disc for the 2" discs.

Shipping has a minimum cost so the difference between shipping 100 discs and 1000 discs isn't much so I usualy order 300 or more discs at a time.

Thanks

Richard

>Sorby doesn't have bearings either. and you have to oil/grease frequently. The main reason I have it is because I sell Sorby here in Israel so I got it for less. =o)
