Thread: Dental Handpiece Motors (Marathon Micromotor)

+1 to the above^^^^^^^
My Dremel, Craftsman version of same, and old blue point single speed rotary tool are all holding up well after 10+ years of service.
Didn't know that brushes were available though. Will get me a set before I actually need em.
Cheers.

Yup, you can do it all with hand tools, in a small space and a Dremel. Hand sand to 2k and then metal polish. You can un-pin by hand with a pin-vice, if needed.

I used Dremels all the time, but not to polish. They do last a long time, have had several for many years, do buy variable speed, with flex shaft, cordless is nice, but not a necessity.

You don’t need a shop full of tools or a lot of space, to restore, but a shop is nice.

I know a lot of guys who do some great work in cramped space, on a budget with just hand tools, don’t let space and lack of power tools stop you. Lots of great ideas in the Workshop forum.

I have a lot of tools. Most of them do not get used for razor restoration. Scales making a little bit. I still do the majority of restores by hand. It is super easy to mess up the lines on a razor with a buffer. There is a long learning curve on getting it right with those. A dremel has It's place and I have one and use it a little bit, cleaning jimps for the most part. I am a big fan of taking my time and relaxing while working on an old razor. It is zen time. It is more about the process than the production or the money. In my view if you are looking at getting done faster you are missing the journey.

You may have a point about Dremels being weaker than they were. Seems the ones at Lowes looked a bit foreign to me as I looked last. A NOS oldie should be had on the bay? I can vouch for those!

Yeah, new/old ones abound on Ebay. Just saw a 2-speed for 28 bucks. A single speed for 35. Shipped. Sewing machine pedals work super with the single speeds. Cheap on the bay.
You could go thru a pile of NOS older model Dremels, I think!

OH! Lookey at this one Dremel makes! Still, a new single speed 100, a cable attachment, and a sewing machine pedal comes in at half.

I've had a flex shaft Foredom for 50 years, changed out a handpiece for comfort and two sets of brushes. HF has a cheapo 1/10 hp one for really cheap with a coupon.
Funny, though I still use the 'bay and auction Dremels with old drill stands router tables, and other accessories more than the flex shaft.
Look for magnetic razor holders on the search.
A good one is here:
Bill's Straight Razor Info: Making the Blade Safety Jig
I've made a few similar. The advantage is thet the blade is tight to the metal which serves as a heat sink also. I have used a piece of steel shim stock over the edge while Dremel buffing and sometimes not.
Have fun! Life is too serious to take solemnly

I wonder if that is the same Bill who made me some magnetic jigs a long while back?
I still recover them with thin aluminum from time to time. Then, you need a demagnetizer as-done. Provided by Darl (Tarkus) ! A few swipes of the spine on this humming thing, it won't pick up a straight pin!

50 years? You are enjoying getting old, eh, Richard?

Wonderful devices! Used in a machine shop.
and, Yes that was Bill Ellis that made the Jigs and one of the early strop shops did also with a heavier aluminum for the blade. The guy got sick and a few here trashed his business. '"Gentleman's Best" as I recall. He had scales precut and a lot of other good stuff.

Not this last month! Been there before and will overcome. Don't ask!
Otherwise...Yes!
