Forgot what you were doing there for a min John think I'm losing it Wasn't the old one useable? Look rather good castings those

Hi
Nick
I want to make it reversable hence 2 eccentrics
John

I worked that out John ... just wondered why you made 2 more rather than just 1 more and use the old one too? Presume they are different to the old one in some way?

Hi
Nick
I have used the original
(i cast 2 just to be safe in case i messed up the machining)
The spare one will be remelted

Hi
Had a good few hours in the shop this weekend
Had a bit play with the rotary table

Time for some filing

The rod ends are threaded left and right hand thread ,this makes setting the slide valve easy

Just a nice big reversing handle and some linkage

Real neat job John.

How did you cut the left hand thread have you got a set of tap and dies or did you screw cut them

Hi
Stew
I have 6 mill left hand tap and die
I also have some left hand unf taps (motor racing days radius rods ect)
John

sbwhart · « **Reply #133 on:** January 30, 2012, 05:32:06 PM »

Thanks John

I was wondering if you'd gone round the back of the lathe and screw cut some left handers.

Thanks Ross

Hi
Been a bit cold in the shop lately

Got a bit more done with the reverse gear

A nice brass top on the handle with a pawl mechanism

Hi
Eventually got my camera back from the daughter
Been busy with my reversing linkage
Pictures tell the story

Runs well in ether direction
It makes nice noises with some cut off
I will do a bit video of it in steam
Then strip it ready for paint
Could be a big mill engine next
