http://www.lathes.co.uk/harrisonmiller/page2.html
Its 3 phase with the standard vertical head (no quill unfortunately)
and has powered feeds. It comes with a machine vice and several
chucks.

Orthogonal Dynamic Balancing
Thu, 06 Aug 2009 21:24:20 +0100
At the risk of overextending an off topic discussion - more
thoughts on home brew balancing.
The earlier orthogonal method is a conveniently simple
method of single plane balancing but it falls short of true
dynamic balancing because it ignores unbalance couples - forces
generated by equal and opposite wei ...

Should I harden a key?
Tue, 4 Aug 2009 04:24:52 -0700 (PDT)
Ive just remade a 4mm section key to fit the end of my lathe leadscrew
for attaching changewheels.
I had to make it from mild steel and file it to an exact fit as I'm
not sure if the key was originally slightly undersize or the shaft
keyway was a little oversize (it hasn't had too much use eitherway, so
shouldn't ...

Orthoganol balancing - twinwheel grinders
Mon, 03 Aug 2009 22:52:43 +0100
A bit of extra info on orthogonal balancing.
With the balance weights mounted close to one side of each
wheel the system balances out the radial unbalance component of
each wheel. However it takes no account of unbalance in the axial
direction i.e. the wobble if the wheel is not properly mounted
squ ...

type of resul ...

Hi There Gentlemen,
I have a Condor mower, which, a few weeks ago stopped, as I was
tackling a particularly tough patch of scrub on a very hot day (in
June!) No spark. The spare for the 8 Hp Kohler single cylinder

problems with it are more ...
