Having produced for the Model Engineers' Workshop magazine a series for the "Lathe
Only" workshop, I commented. "Having now completed all the items for the series I
am fully aware how versatile the lathe only format is. Having just a lathe is no
bar to having an interesting hobby, or being able to undertake quite involved projects."
However, whilst making the various items I became aware that even though a milling
head would not greatly increase the lathe's capability it would make some operations
appreciably easier, if only because it would be working with a horizontal rather
than a vertical work table. As a result, I decided to equip the lathe with one to
my own design, Photograph 1. This project is a result of my endeavours and will hopefully
provide an interesting project for some and for others a realisation that owning
just a lathe and a drilling machine is no bar from undertaking interesting projects.
I also made the stationary steam engine, “Tina”, using the milling head to illustrate
its versatility and this is included in the Processes section of the website.
I decided that it would be powered from the lathes spindle giving a range of speeds,
rather than with a built in motor. Also, as it is intended to be used in a workshop
without a milling machine any milling in its construction should be possible using
the lathe itself. Actually, having completed the design, I found that no milling
was necessary if one was prepared to finish the edges of the cut plates by filing.
With that decision made I could have started with a blank sheet on which to commence
my design but was aware that I already had a milling/drilling spindle that would
satisfy the requirements admirably (well almost), and just needed mounting. As this
featured in my book Lathework a Complete Course there could be others who had made
the spindle and would benefit from this approach.
My reservation above “well almost” was as a result of the limited cutter diameter
it could accommodate, 6 mm or 1/4". The spindle was designed to take a drill chuck
with a 1/2" x 20 TPI threaded mounting, and with drilling very much in mind this
had a major impact on the design at the time. Now intending to use it largely for
milling and on a fixed head, I felt that being able to hold cutters up to 12 mm was
The larger cutter would not perform as it would in the average mill/drill but larger
surfaces could be covered when taking wide but shallow cuts for surfacing. Just how
heavy a cut could be taken would only become apparent when the head was put to use.
