RMweb Premium DLT Posted April 1, 2014 RMweb Premium Share Posted April 1, 2014 I always find Slaters plungers too stiff and endupcutting to springs in alf or less - too much friction will wear the wheels over time and you are better off with a much looser pressure. Can you modify your 04 Paul R I presume these were 7mm scale plungers? I don't use plungers in 4mm for thaty very reason, but has anyone tried using 4mm scale plungers on a 7mm loco? Or are they not physically big enough? Just a thought, Dave. Link to post Share on other sites More sharing options...

OzzyO does and with very successful results. See his thread Link to post Share on other sites More sharing options...
pwr Posted April 27, 2014 Share Posted April 27, 2014 OzzyO does and with very successful results. See his thread I never thought of that. I might try it. I guess the holes will need to be drilled smaller which is not a problem if you have to drill anyway but if they are pre-drilled then more work would be required. Nonetheless a good tip.

Poggy1165 Posted April 28, 2014 Share Posted April 28, 2014 7mm scale is addictive. I sometimes regret not moving to P4 instead, but I'd never go back to 4mm scale. Too late in the day, apart from anything else. The scary thing is, I now find myself tempted by Gauge 3! But I will resist... Link to post Share on other sites More sharing options...
81A Oldoak Posted April 29, 2014 Share Posted April 29, 2014 7mm scale is addictive. I sometimes regret not moving to P4 instead, but I'd never go back to 4mm scale. Too late in the day, apart from anything else. The scary thing is, I now find myself tempted by Gauge 3! But I will resist... I dabbled with P4 briefly about three years ago. I built a point, converted a couple of wagons and acquired a P4 converted Dapol Pug on eBay. It was easy, but too late and just too small compared with 7mm scale. My sense of perception has changed and 4mm scale looks like 3mm scale to my eye. As for Gauge 3, if temptation is a problem I would advise you to stay away from the ALSRM show at Reading on 10th May.

puddlejumper Posted May 15, 2014 Share Posted May 15, 2014 Hi Paul, That's a possibilty- they do seem overly sprung, and rather pointy- but I don't think it's a cause of the jerky running in this case. I did manage to get it to run a lot better with careful tweaking on the motor/ gearbox/ drive axle assembly (screwed into place via oval holes to allow adjustment fore and aft) and the quartering on the drive axle again, but it's still not right. Acceptable forwards but still a little rough backwards; I'm sure it can be sorted but it'll require a rather more delicate (and experienced) touch than I possess. Does anyone know of any people who specialise in such repairs? Coming from 16mm live steam there are several individuals who specialise in restoration, repair and servicing of locomotives, but I've no idea if there's folks doing something similar in 7mm. Realistically I think I may cut my losses with it, and go back in time a few years with a nice BR black pannier tank... the difference in price does pay for a fair few wagons though! Thanks for the welcome by the way Bob- don't hold your breath for progress on my own layout, but I'll keep the thread updated with some pictures of activities on the club's layouts, and member's layouts I've wrangled running rights on... Bit late to the party but welcome along to the joys of 7mm scale, it quickly becomes quite addictive, assume the 04 is a brassworks one? My 08 did the same......only more so, quartering on offside centre wheel suddenly became 45 degrees out!! Drop the connecting rods off, gently pull the wheel off, quick rub with very fine emery board around the axle stub and refix wheel correctly quartered (I did it by eye) using a tiny drop of loctite, job done..........on the other hand if you are serious about cutting your losses, drop me a PM, I've looking for one of those for a while now Link to post Share on other sites More sharing options...
