Micro Drill Press

It has been a busy couple of week but I wanted to be able to drill small holes with very small drills in metal using the 3/32 shank and 1/8th shank drills.

After looking around at what is available I decided I would build my own.

 

It went through a number of iterations during the build

The first version had a round quill but i was not happy with it so went for a square one with a dovetail slide.

The other thing i was not happy about was the mistake of putting the rack at the front, this created an issue of direction so added a second pinion, needless to say is was beginning to feel like a rabbit hole that was getting deeper.

 

This is the current state of the press the motor is a 9v dc one and seems to have enough Jam for the tiny drills.

I have been drawing it up as a design build and making the changes as things change.

Very nice Michael, and it does EXACTLY what you want it to do with precision (and a lot cheaper than buying one also I bet :))

 

cheers

Very impressive, looks much better than anything I have seen commercially. I have been looking at the proxxon ones and they simply don't compare.

Hello Michael

 

I thought you might like more detail about my approach. Like you I didn't like the commercially available units.

 

The press was designed around my micro drill (now very old - at least 25 years).

The base is the face plate off the lathe - rarely used with the lathe.

 

The main column is the central rising shaft from a broken camera tripod ( the legs are still waiting to be made into a 3rd hand ). If you look you will see the pinion gear which engages the rack. It was originally part of the hand lever which raised and lowered the rack.

 

The horizontal plates at the top and bottom of the rack are rigidly attached to the rack and they carry, and are rigidly attached to, the vertical bar which sits to the right of the rack. This forms a very rigid structure on to which the sliding frame which carries the drill sits.

What is a bit odd about this arrangement is that the 3 armed handle for raising and lowering the drill actually goes up and down with the drill.

 

The photos are probably clearer than my explanation.

Interesting how the same problem can spin off many solutions. Not quite as elegant as yours but it works and appeals to my need for recycling.

Until I had seen this thread I hadn't considered making my own but how easy to make without a milling machine etc?.

That looks good Keith.

Regards Richard

Oh, Michael. You've been tinkering again! I had to smile, though.

 

I used to own a vintage Dumore sensitive drill press which I reconditioned. However, I never really used it, so sold it some years ago. Now, if it had been more like your design....

Beautiful work as usual, Michael.  You never cease to amaze me.  I agree with Mark, you need to come out of Retirement and start a tool company.
