Hi all. I am having a few doubts about the lubricator on the ModelWorks kit. It is fixed at footplate level at the back of the engine being driven from an eccentric on the trailing axle. When operated by hand it pumps the oil through fine. Actually I used a cordless drill to turn the lubricator shaft running at low speed. However the lubricator arm does not seem to swing far enough to operate the clutch drive when driven by the eccentric off the axle. Model works told me to connect the eccentric strap to the upper hole in the lubricator arm in attempt to put more movement through the clutch but whilst an improvement, it still doesn't look right. Since many constructors are ahead of me and appear to be in steam I'd like to know how their lubricator functions. I have fitted the re-designed eccentric strap as supplied which suggests that ModelWorks have come across this problem, though Debbie at ModelWorks told me it was a new one to her.
Regards
Mott

Jon,I was never dead keen on the winson design,I haven't seen modelworks version,so can't coment too much.However,you could also drill extra holes to give moer throw on th operating arm,or scrap the whole lot and buy an old fashioned ratchet drive version from Blackgates,reeves etc.You pays your money......ect.
Phil
ps you'll have to sort this one out before you start running - no oil= worn out cylinders /piston rings whatever!

Mott I had a similar problem with my ModelWorks lubricator, after contacting them they said part of the problem was the clutches and shaft being used were 3mm. The 3mm clutches were very weak and prone to slip or not work properly causing a poor oil supply. Ian at ModelWorks said that the one's supplied will work, however, they must be kept clean and degreased at all times (bit difficult that!) to ensure they do not slip and work efficiently. They said they have now beefed them up and use 4mm clutches which are much more robust, unfortunately the 4mm clutches aren't interchangable with the one's already supplied. I went and bought a new one from the Steamfittings website which is supplied with 4mm clutches and have been extremely happy with it. (much better than the ratchet drive version in my opinion Phil and half the price!)  Regards Mark |

Well as I said,you pays your money,you takes your choice-I've got no axe to grind.I just think that a proper ratchet drive is a better proposition.

Phil and Mark. Thanks for opinions. Phil , exactly because I was worried about lubrication that I latched on to this thing. Can I ask Mark, did he find that with the 4mm lubricator the fore and aft movement of the eccentric strap gave sufficient swing to the lubricator arm for the clutch to work ok or did he do some further mod. in addition to fitting the new lubricator.Regards Jon

I didn't do any further mods to the lubricator arm and it seems to be supplying sufficient oil. So far so good anyway!

Greetings to All. Modified the lubricator on my 1400 at the weekend by fitting the 4mm clutches. Bought the bits from www.steamfittings.co.uk for £8, which is a lot cheaper than the £27 price for a ratchet driven pump without tank! Turning the pony wheels now drives the pump through the full cycle, but I have drilled some extra attachment holes in the new arm in case the lower fitting does not pump through enough oil. The cylinders will need plenty if those 'O' rings are to last more than a season! |
