I have considered building a sliding drill mount for a micro drill, as all the normal ones seem to have unacceptable play in them so the drill point moves off-centre as it is lowered.

A camera sliding focus plate is what I have in mind. They can carry a d.s.l.r.

I would fix the base of the slider to the drill press vertical shaft, make a suitable lowering lever and attach a return spring to the sliding carriage.

Perhaps these pictures should help you envision what I mean.

I don't think that such option could be available here. I will ask anyway.
No sand? No compressed air? Miguel, I'm beginning to envision your electric grid being powered by Gerbils! :D

We have a lot of sand, maybe more than the rest of the world. Just pay a visit to Varadero beach and you will understand what I'm talking about.

There is a lot of compressed air too. In the garages to inflate the tyres of the vehicles.

Can't see the relation. Yes, our electric grid is nothing compared to yours, but there's no relation with having a sand blaster at hand.

We're a poor country, yes, no shame on that. I do what I can with whatever I have at hand. That's my reality, very diferent from yours, so I find your comment as inappropiate and partly offensive.

If I can help with any DIYer idea, be sure I will.

We in Canada were allowed to visit Cuba, so I can understand the position you are in.
Nice friendly place to visit.

Some details about what I have done.

There are some rusted parts yet which are not definitive and i will replace them with other pieces that I have to have done by a turner. The fulcrum of the lever being one of them.

The springs are those used on the valves of internal combustion engines. I'm trying to gather a complete set of the same time. In the future these springs will have separators between each of them, to secure that they do not touh the inner tube.

The final lever won't be so flat as I have no available room, so I will make it at about 30° from vertical line to save space.

The motor is made in the former Socialist Republic of Bulgaria, so, a very old one but still in very good condition.

The chuck is not definitive neither as I have one "brand new" one (read: unused 25 years old one)

Miguel, I'm sorry you found my last post offensive. It would appear that humor there is also in short supply.

That said ... nice work!

The fulcrum for the lever. I want to cut the corner of the flat piece, but my hand and my saw don't want to do it. I will do it some day.


I included an auxiliary bar to help me disassemble the drill. I can screw the shorter bar to the longer one to use the lever to lift the drill and remove the springs, Some time in the future I want to make separators for the springs.


The lever has a right-angled handle for easier operation. I will mount a switch in the lever to turn the drill on and off this way.

Another update on this project which althought it's operational right now, it is not finished yet.


This is the "brand new" (NOS actually) chuck, and the two CFLs that I fit there to iluminate the drilling area.


Details of the CFL fixing


The switch in the lever to power on/off the motor


The covers for the CFL. They will be painted in blue when finished.

It is my intention to convert this area of my workshop in an all-in-one tool system, including a sheet bender, a sheet cutter, and right now I'm thinking to use the drill as a lathe for minor turning works. Maybe a bit ambicious but I think that ambition moves the world.
