I have a Cameron micro drill and a Vigor (Japan) watchmakers drill press.? The Cameron is a lot better with #60 to #80 drill bits.? Probably because the chuck is better (Albrecht Keyless).? The Vigor is OK up to about 1/16th.

Micromark has a couple listed that may work for you...

The Cameron drill press I found online
has a price tag of over $1600.00. I can’t imagine what might make it so expensive.
I have been thinking of a way to to improve the Unimat spindle while increasing the travel and better depth control. I have been relying on a dial travel indicator which works well but adds more apparatus to the setup.

Beware of drills with collets - some of them (EG Poxxon) only hold a limited number of sizes. It's OK if you have drills with 3/32" shanks, or similar, but if you have plain number drills many will not fit. If you have ER collets the smallest you can hold is 0.5 mm - I have some very small drills (0.05 mm) which are on a 1 mm shank.

I am looking for recommendations for a small drill press for the smaller
number drills.

FYI I saw at least 14 Unimat motors on EBay today. I have never seen so many for sale at one time.

I have one standard OEM motor bracket and two low speed motor brackets to use with my two 24 v motors. That should cover most any need I may have.
Dick

Not sure what the distinction is. It is best to obtain low speeds using the pulleys, and then use the variable speed on the motor for fine tuning. That way you get the maximum available torque for any given speed, You could use the usual motor bracket with one idler pulley or the less common low speed version with two idlers. Or you can make up some equivalent system, whether a motor bracket or not.

Is it best to use the standard original equipment motor bracket with the three pulleys or to use the slow speed accessory ?motor bracket with the 24v motors?

These are very useful photos.? I am currently working on something similar , as per attached photo.? However, I machined an aluminum block to fit into the Unimat mount and am securing with screws.? Am I to assume that the screw is 1/4-20 and the support rod is 5/16?
Please note that this device is supported with a cut off Unimat bed.? When I did this previously, some here were crying and complaining what a sacrilege it was to cut up a Unimat.

Thanks, Kevin!
This one is very similar to the one I was referring to, and very well done.
As most of my milling operations are carried out on the Unimat I could definitely definitely benefit from a more accurate means of location than what I currently use as well as a dedicated setup.

Some years ago there was a member of this group who built an add on device for accurate vertical positioning. I think it was known as a Unimat Vertical Positioning Device. I believe he sold a few copies.
Would anyone here be able to point me in the direction to a picture of this device?
