A Lorch Micro-Mill that never was ...

Lovely Machine, was good to see it in action also I now have a better sense of the size.

Some belated thanks, gentlemen !

 

********************************************

 

I could not refrain from some more toolmaking. I will probably add various small attachments for particular purposes, as I am using the machine. Here is a small clamping table for flat objects.

 

 

 

It was milled from a piece of flat steel and the arbor for the 5 mm collet was hard-soldered in. The area underneath the slots is recessed so that I don’t need a wrench for holding the nuts while tightening the screws.

 

 

It allows to securely clamp pieces of sheet metal etc. for engraving or other types of milling operations. It can also be clamped in the small holder I made for the micro-vise.

 

You will see soon in the SMS WESPE thread, what sparked making this tool ...

Made a fly-cutter for the mill over the weekend:

 

 

 

I could have turned the blank on my lathe, but I was able to source some 6 mm-lathe blanks in the USA at a reasonable price, which saved a lot of shop-time.

 

Worked on some skylights for SMS WESPE that were milled from a solid piece of Plexiglas/Perspex and it works like a charm - if sharpened properly.

Where did you get those small (6mm) blanks from in the USA please Eberhard?

Hello Wefalck,

What stunning machine work, ingenuity and very pretty to look at

Unfortunately, milling operations with the dividing-head in the upright position leads to the accumulation of swarf between the spindle-head and the dust-sleeve made earlier.

It was also felt useful to have some kind of indication of the angular position of the spindle when using the indirect dividing gear, particularly for round-milling. In order to overcome both problems, a graduated dial was manufactured, that has a friction-fit to the spindle-head. It was made in the same way, as the dials described above and marked in 5° steps.

With its round-knurled ring it can be zeroed. Because of its tight fit to the spindle and its shape, it sheds the swarf away from the spindle.

Very nice work Eberhard; you have a very nice, practical and efficient tooling setup there now.

 

cheers

I'd like one of these, a fully functional miniature Bridgeport!

I've been dreaming of something similar.  I will continue dreaming while I watch you.
