This is about lubricators but a bit off topic.

When I was first setting my shop up I was short of kit and and cash to get it so I started to make bits for L. Masons Mini Traction engine I had noticed that nearly all the engines that came up for sale on fleabay didn,t have lubricators, there small and tricky to make, so I set too and made some in batches of five.

Her's a batch of five

Just to give you an idea of size the tank is 5/8" square, her's a ratchet against a UK penny.

They commanded a good price, and I was able to get some good kit for my shop, a lot of the people who bought them started to ask me for other bits, but thing started to get too much like work :hammer: and not a hobby, so I gave that particular enterprise up.

Cheers

nice bit of work there Stew and I agree when your hobby starts to feel like working something has to give

so back to the hobby mate :D

NickG:
Great stuff Stew, bet this one was like a doddle compared to those then ... you are a lubricator guru! :thumbup:

Would it be possible to give a bit more info on the roller clutch things? Where did you get them and how are they mounted?

Thanks,

Nick

Hi Nick

I got the roller clutches from Arc Euro http://www.arceurotrade.co.uk/Catalogue/Bearings/Needle-Roller-Clutches, the design calls for two I think you assemble them so that they work opposite to each other, they just slide down the 1/8" shaft and work, I've not tried them on the lubricator yet as I need a reciprocating action and I'll only get that when I've got it assembled in the loco, which won't be for a little while as it requires a complete strip down so I'm going to wait until I've got a few strip down jobs waiting then do the lot together. One fits in the main body of the pump the other in the activating arm.

You can see in the pic

I'll PM you the drawings tonight if you like

Cheers

Stew

NickG:
That'd be great, thanks Stew :thumbup:

So it's a sliding fit on the shaft is it a tight fit in housing or doesn't it matter? Oh just looked at your link and it says it is a press fit.

They look a better and easier job than ratchet and pawl and as I said there's an issue using the ratchet and pawl on this design. Thanks again

Nick
