Hi Guys,

My first comment on your site. Please forgive any issues or errors. Building a mechanical lubricator for a “Doris” Black 5. Complete apart from the toothed drive cog wheel and pawl. Any tips on how to machine this part other than hand file teeth and then maybe case hardening..

Many thanks for any input or tips.

I seem to remember that the ratchet from an old cigarette lighter being mentioned as a way round this issue. Good luck. Noel

I seem to remember that I bought mine from Reeves. Something like this:

To make the ratchet wheel for my lubricator, I held a piece of round steel in a collet in a rotary table and used a dovetail cutter in the mill to cut the teeth. The teeth in the round steel were much wider than what was needed and a slice cut off to suit the width required for the lubricator. (I now have enough spare material to make many more lubricators). The material used was silver steel but I did not harden it. The pawl is made from brass and both have not worn after 8 years use.

Thanks guys,

I cannot believe the support I have been given in less than an hour of the original post. I have ordered a few Ratchet cogs from Reeves 2000 but I like the challenge of the dovetail cutter in rotary table on the mill.

your lubricator looks outstanding Paul. Far more robust than the one called out for the Doris. Can I ask what locco it is for?

thanks again guys

Hi Kevin,

The oiler is based on a Fosters type lubricator and was made for my 6″ Ruston Proctor SD road locomotive (AKA traction engine and golf cart)

Wow.. a tad bigger than my Doris.

just ordered dovetail cutters from RDG. Did not know if I needed 45 or 60 degree so ordered both. Can you remember which you may have used?

60 degrees but either should work
