Nice work but I'm intrigued. One round column and no key way, how does it keep aligned?

I was wondering that but I think there's no carriage in the way that most lathes have. It's moveable but doesn't travel, if you see what I mean. That just leaves cross slide and top slide to do the work. That probably means that a taper can't be turned easily as I don't think the top slide rotates, right?
The tube seemed to be slit in some of the pictures so it could be there's a key to at least guide it if moving the carriage by hand. I was thinking that two columns would keep the carriage straight but for a field unit to be pulled out the crate and set up anywhere quickly, that would probably be a pain to align/level.

Nice work on it Bruno.

Rotate?
Have a look at 3rd photo in posting #3926 (previous page).

I stand corrected. I blame the tiny screen I was surfing on previously Tapers are entirely possible then....I was thinking it would seem an unusual thing not to be able to do for armed service use - bound to be some tapers in equipment or weapons.

Well then.
The machine is a mechanic's lathe. It has only one plane slide and one top slide. The complete cross slide is moved on the pillar and the turning work is done with the two slides. The turning tool must be reset to turning center each time the complete unit is moved. It is not important that the complete slide is in the horizontal position. It should be in a roughly horizontal position.
To make the alignment a bit easier I built a support under the carriage carrier. This makes the alignment a little bit easier.
This has already been provided for when aligning the tailstock.



However, the lathe should be mounted on a stable base. The Bosch company provided the lid of the storage box for this purpose. For this purpose, the lid was equipped with mounting threads.

I have attached my personal logo to all parts.
Here a turning test with the new cross slide. The small pin has a diameter of 0,5mm.

I also found a solution for the missing drill chuck. The mounting thread on the turning spindle and on the tailstock has the dimension M14 x 1,5mm. A normal gear rim drill chuck for drilling machines has the thread 1/2 x 20 UNF.
I have modified a 10mm drill chuck for this purpose.
For this purpose, a 10mm shim was clamped in the chuck and this was mounted in a collet on the lathe.
The 1/2" thread was turned out to 12,5mm and then the M14 x 1,5mm thread was cut. A short pilot hole of 16mm was drilled and the drill chuck was drilled through with 8.1mm. So you can also drill through drills up to 8mm diameter. The original drill chuck was clamped over the collet holder and could only clamp up to 6.5mm.

In sharing this project with other people,

very innovative and interesting project - glad you did share it and thanks for the detailed explanation

The sliding bar for the saw table was not complete. There was only the fence angle and the wood support, the bar was completely missing.
I made a new bar incl. all parts belonging to it.

This is the condition when I unpacked the part.


These are the manufactured parts.


The assembly sequence.


The angle stop complete.

The cross slide was pre-milled and left to rest overnight to relieve internal stresses.
After the cross slide carrier was finished, the dovetail could also be milled and adjusted in the slide.

From scale line to scale line the graduation corresponds to a diameter deviation of 0.1mm.

The connecting part between plan and top slide is still missing.

Bit late to the party.
That eagle looks like the Moto Guzzi emblem, identical in fact.
Stunning work by the way, congrats.

The eagle is in fact a stylized version of the Guzzi eagle. A friend of mine (commercial artist) drew it years ago. I have received permission from him to use it.
The logo is a result of my passion for Guzzi.

I took a slightly different approach to the drawbar-wrench-and-hammer-tool:


I simply got the cheapest wrench that was convenient from the local auto-parts store. Cut off the open end. Milled a slot in a piece of brass rod. Silver soldered the handle in to the slot.

The grooves in the brass head are to limit the size of chips that will eventually fly off.

Just wanted to say that this a GREAT piece of work! I've been wanting to build one for a long time and your design is the best I've seen! Well done!

For my Pillar Tool I designed a rotating table holder. It can hold the drilling table as well as various tool holders. Background of the construction is to bring impact punches in a specific angle on surfaces which are inclined to the axis.

The measurements are in millimeters and adapted to my Pillar Toll. If someone wants to reproduce the part, please adjust the dimensions.

I once started to make the rotating table holder.
I still had a piece of GG25 Cast-Iron.
But it was enough for two separate parts, the discs come in between.
Today I milled and drilled the holes for the clamps and the holes 22mm and 20mm.
The clamping stones were made with the column drillings.

Predrilled holes. The clamping stones are inserted.


Spindled out to 21.5 or 19.5 mm and then finished with the machine reamer.


Machined on all sides with the cutter head.


The two discs for the twisting device were cut on the band saw.


The thickness of the disks is adjusted so that I get a hole distance of exactly 90mm at the end.
