Dear Clayarters,
one thing I forgot to mention about the fly wheel. Mine was the same weight =
(150
lbs) but all the weight was at the rim. I first cast concrete (lasted me 20
years of constant use) and bolted the ring to the wooden flywheel, I have =
now
used solid steel rounds, six in all, also bolted to the same wooden =
flywheel.
I must point out that it can outthrow any standard electric wheel for weight=
and
efficiency. You use a different technique throwing on a momentum kickwheel. =
As I
said in my previous post, speed is not necessary, and when you are throwing,=
the
wheel slows naturally and you adapt to the rythm of the wheel. You end up
throwing much more efficiently, without fiddling about. The standard =
electric
wheel is used far too often just for speed, as it has very little torque. I =
have
just got delivery of an electric wheel that was made specially to my
specifications, extremely low bottom speed, with not a great top speed, but =
with
plenty of torque. I have yet to give it a full trial, but I had no trouble =
with
slowing wheelhead speed with 30lbs. I'll try my normal 50 - 60 lbs over the
weekend, throwing chimney pot barrels and mouldings, all done in sections =
ands
then joined together when stiff, whole pot should weigh about 250 lbs.
Don't give up using a momentum kickwheel (certainly don't fart it up by =
putting
in a treadle - a typical Leach bastardisation of a superb and simple =
solution),
just learn to use it correctly.

Mark ,
I am surprised you don't use a " Scotch Friction Wheel " .
Gives the best of both worlds i.e. speed and lots of toque at
slow speeds . There must still be some around in England. One of
mine is about 150 years old :) .

Mark,
have you heard of or seen the Cornish terra-cotta method of
easing up large lumps with the left hand on the outside & the
right inside . Then switching to the right side for knuckling up
?

Dear John,
yes I have and use it regulary on some pieces. Also regarding Scotch
Friction Method, as I said in a previous post that I'm not a great believer
in mucking up something that works extremely efficiently. Another point
being that introducing an extra bit of kit into the momentum set up would
create a certain amount of confusion for me. If I want to use an electric
wheel I will do so and a momentum wheel when I want to use that way of
throwing.
I am not chucking out your ideas into the delete din, it is just not for me
and the way I work.
