Slaters MR/LMR Johnson '1262' Class 0-4-4T 7L011 in Scale 7

[John Walker]

This is my next build for HMRS in Scale 7.



As with the Kirtley Goods described here, Slaters MR/LMS Kirtley 0-6-0 Goods (Johnson) 7L007, there is less than no clearance between the splashers especially across the smaller section over the coupling rods. I have sent the O gauge wheels to Colin Dowling for reprofiling with a request to reduce the width as much as possible. When I get them back I can have another look and see whether the splasher fronts will have to be removed from this etch and refitted. I am not sure how far up into the splasher the coupling rod and crankpin extends.

I had to take quite of material off for the Connoisseur G5..

Not end of the world though..

John,
When I decided to build a GCR class 11A, LNER D6, in P4 from a White metal DJH kit, I had a similar problem with getting the wheels into the splashers. I solved it by using Stuarts Micrometer Engineers marking paste. I smeared this blue paste onto the flanges and tried them in the splashers. When I removed them, I could see where they had touched and I ground off the tell tale blue marks with a dental burr. After many repeats I succeeded in obtaining sufficient clearance. It helps that with a 4 coupled engine you do not have to allow for lateral movement of the axles.
Keep up the good work,

Louis

John,

You can turn Slaters wheels down to very close to scale thickness at the rim but sometimes it can be difficult getting the boss to size without spoiling the spoke profile. The crank pin bushes, if using the Slaters ones, can have the flange reduced to virtually zero, just enough to stop the coupling rods from rubbing.

On my Caley 19 class, in S7, I have zero sideplay on the front splashers but inside the side tanks the sky's the limit, well not quite but you know what I mean. The motor drives on the 2nd axle and the whole assembly can slide sideways. The bogie is on a fixed pivot just in front of the first axle with plenty of swing at the rear.

Good thing with this kit is that it's etch, so you'll see straight away if anything needs taking away..
