For several years I had an Eagle hand operated machine with no coolant
facilities. Did some good work on it but it was quite a chore -
eventually automated it with landrover windscreen wiper motors which
made things better. When I got the J&S540 it was like chalk and
cheese. Hydraulic feed is so much smoother than hand feed, and also it
can be left to get on with things while I am occupied elsewhere. I now
find I use the machine far more as not only is it far less of a manual
chore but the accuracy and finish attainable are much better. 540s
used to command huge prices but in recent years ebay has seen some
apparently good machines go for peanuts.
