Thread: Clutch for geared head lathes
08/04/2013 18:38:41

Hi Mike

Model Engineer Vol 210 - No's 4452 and 4453. I am sure it could fit the M300, albeit with some modification..

Sorry I cannot send a link as I am not certain where the drawings are on the site.

Hi,

I have a Harrison M250 and will def. be making this clutch.

HOWEVER, is it me or are there some drawings missing??

Page 519 the pushrod housing is supposed to be Fig 8 - but it is the pivot mounting block and there are no dimensions for for the attachment plate.

Am I missing something??

Thanks for that - I have made the bogie, and on my plans the guard iron (on sheet 5) are 3/32", and that seems OK.
 
My father used to live in Chesterfield, and many years ago on a visit to his parents (I am ashamed to say about 30) he went to Norman's house and bought my plans (I think they cost £25!!!).
 
As I was a poor teacher (pause for violins please) the plans sat in the cupboard for years, and now I have retired I have started in earnest. Hope to finish before I pop my clogs!!!!
 
I agree with your comment about a coupler - that would make sense. I spoke to a chap at Ally Pally exhibition who had a 5" Brit on display - and he has simply drilled down through the piston - bored a seat - placed a ball bearning in the seat and then installed a small rod across the top. He said that as the top of the cylinder filled with water, the ball "floated" and the water drained out.
 
Please get in touch if you think I can be of any help - I have just started the cylinders - Oh how I HATE cast iron.

Hi
 
I am building the loco using Blackgates castings.  I cannot for the life of me see how the Brake cylinder water valve (on sheet 7) fits onto the brake cylinder.  One end of the water valve has a  ¼" x 40 threaded hole  with a countersunk  (to presumably match a pipe and olive), and the other connection is a ¼ " x 40 threded hole.  The brake cylinder has a ¼" x 40 threaded hole at the top.  I cannot find any connector on any of the sheets - to connect the cylinder and valve..
 
Is anyone making this loco (or has made one)? and can put me in the right direction?
