Hi Nick

Yes fingers crossed

I spotted that the drawing does call for oil feed in the rockers, with me remaking them I just missed them. To oil the loco I guess the best way would be to make some long get anyware nozzles for you oil can.

I've not made the lubricator yet when I do get round to it I'm going to follow a design from ME thats uses poppet valves and clutch bearing to get away from the ratchet arm design I think this will be less troublesome.

Sorry I havn't built the axle pump yet that's one adventure to come along with the lubrucator.

Cheers

Well persitance payed off:-

After checking and modifying the linkage yet again I put it all together, with the vavles as drawn just couldn't get the valve timing correct so decided to cast caution to the wind and modify the slide valve to the sizes I'd worked out and tested on the dummy.

Made an adaptor and pluged bits up that are not required for air runing, hooked it up to the compressor and turn the valve and away she went

Whops just realised the video is of her running in reverse she go in both direction, just wind the reverser and she changes direction.

Just ran her for an hour
