A Lorch Micro-Mill that never was ...

Recommended Posts

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.

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.

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.

About the NRG

If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.

The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.

The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
