That would be great to use with an er11 collet chuck for mid to larger sized screws. The collets range from 1mm to 8mm i believe. They come in different lengths, the 100mm long one is the most widely available and just needs to be cut to the desired length. The er11 collet chuck and a set of metric or standard size collets can be had for $25-$30. I'd leave the pin chucks for the really small screws. That's one easy to build design for those that want to make their own. Great video, thanks!
It seems to work well but I don't really like the two other adjusting screws rubbing on the emery paper also. Maybe just a strip of emery paper for the clock screw and the feet running on the granite block. You could then make the end of these screws half round to reduce resistance to movement.
Hello Tommy, Interesting review... if you do make the tweaks suggested it would be good to see the final product sometime in the future... one thing that came to my mind was having UNF threads make make fine adjusting a little easier. See you on the next one. Take care. Paul,,
I’m inclined to agree with Paul. It seems that fine threads would be better for both the legs and the clamping screw, if one accepts the slower action of such screws.
Made something similar at school it works far better than the old screw polishers once your used to it. Pretty sure my teacher did a blog about it on watches by sjx
Very good tool. Similar your observations i would agree on whats being mentioned. Though the grip for the pin vices, it should have a block with a v (90degree) like the commercially thread tap holders, inside the hole thus giving a good hold pin vice holding screws to be polished. I think the mirror wiil get scratched soon with initial contact. The other 2 screws i will give 2 domed screw on heads(self made on a bench lathe and polished as well) that will allow smooth movemnt on the sand or water paper. Just my 5cents but other wise a good tool that I would also certainly use🙂👍
It’s lapping film, a thin plastic sheet embedded with fine abrasive. They are available in many color-coded grades from roughly 1500 grit to 6000 grit as I recall.
I think I would also have those two adjustment feet to be spring loaded because in theory you might be putting an angle on the screw head with that 800 paper
I prefer to polish flat screw heads on my lathe. I assume pin vices that have a round tightening nut will be secure in this tool I'm thinking of the Eclipse ones. Thank you Tommy.
Thanks for the demo and for sharing your thoughts. Will look to pick one up when available.
Inwas waiting for the next one. Enjoying this series!

Interesting tool. I like the concept. The concept could be used to make any small square flat.

Tiene varios defectos diseño muy mejorable.
PS my dad and I used to run time lock repair center it was called Nationwide timer repair this time locks where used on vaultdoors in Banks
Great review Tommy, looks like a great piece of equipment.

Looks great but why not have a brass plate with two screws as legs and a selection of holes the other end? Wouldn't take long to make surely...
That’s the basic concept, yes.

Thanks, felix crab. I found the article, titled “Explained: the fine art of black polishing AKA Spéculaire”, on that website. The images are superb.

V-groove in the pin vise locking nut?

The ‘dog’ is a Gents C7 electric master clock impulsing every 30 seconds.

What is the yellow lapping paper?
It’s lapping film, a thin plastic sheet embedded with fine abrasive. They are available in many color-coded grades from roughly 1500 grit to 6000 grit as I recall.
Spot on. This particular one is 1 micron.

I suspect they will clamp okay. I haven’t tried any though.
Not brilliant for the lathe bed.
