Re: MR Johnson 0F

Hello Steve, For what it is worth my article in Snooze 208 (page 18 et al) concerning Alan Gibson brass wheels features this same loco with the body from a K's kit. My chassis uses Alan Gibson milled side frames and (being split axle) simple pcb spacers. I have just had a look at Colin's recent cata...

Re: Tim V's workbench

Sorry - me again. I forgot to add in your quest for an understanding of the historical building fabric of the area you may find something of interest in the Conservation Area Appraisals carried out by the local planning authority. I have been on the local council web site and have found this one rel...

Re: Tim V's workbench

Very interesting Tim. I was unaware of the thread on RMWeb so am coming to this rather late. The reason for this post is that this reminded me of the horse (and man)-powered plateway less than half a mile from where I live and known as The Ticknall Tramway. Work on this began in 1799 to take limesto...

Re: Gibson crankpins

I have made a little progress having followed some of the comments and advice on here. The main difference has been to increase the size of the initial tapping drill size from the 0.75mm I have used previously to 0.85 mm. Having run my 1mm tap through this the crankpin does screw through albeit with...

Re: Gibson crankpins

My thanks to all who have replied. In an effort to help others and liking the idea of a close up of the tap and crank pin side by side I have taken a photo (attached). This is with a decent macro lens and as close as I can get. In retrospect I should have used a deeper depth of field as the tap is o...

Gibson crankpins

Can anyone tell me please what the exact size/specification are Alan Gibson crankpins? They are stated to be M1 but elsewhere in the catalogue it refers to them as 14 BA. I know that BA technically is metric but there are subtle differences in pitch or some such which does not mean they are intercha...

Re: Split axles in use

Interesting thread. Wherever possible these days I use the Alan Gibson brass-centred wheels (see my article in a recent Snooze). However, the range is limited (as yet) and even I have to resort to plastic wheels and the problem of shorting that has been outlined here. I too have had problems with th...

Re: Instructions for MR Kirtley Well Tank 0-6-0T

Well done Julian, that is looking good - some nice clean soldering. You say that running could be better - can you elaborate? Is it a once per wheel revolution problem? If so it suggests a quartering/crankpin clearance issue. I have now built three outside cranked locos (all Kirtleys) and have found...

Re: The Portescap RG4 is reborn!

But is a Portescap really that much better than, for example, a Mashima with an HL box? It all depends on what you mean by "better". Is better more powerful, smoother, quieter? The Mashima motors are streets ahead of the Anchoridge D11/D13, the "go to" motor of 25 years ago and ...

Re: The Portescap RG4 is reborn!

Keith, I believe the Micrometalsmiths box was the forerunner to the FD01. I don't believe they did a smaller box like the FD03. This is evident by comparing the specifications and drawings on Page 2 of the Slaters pdf with the one from the Scalefour archive. Like you I have the larger box, and indee...

Re: Tender Powered 4-4-0

I am currently building a Kirtley 0-6-0 tender loco (OK not a 4-4-0 but some of what follows may be relevant). In many ways it is quite normal fare - Comet sprung chassis (made for the 4F but the axle spacing is correct) and Gibson wheels (but my favourite brass-centred ones with the crankin bosses ...

Re: Driving wheel axle material

I have had concerns about wobbly wheels when using the GW quartering jig (a most excellent tool), but I have worried about applying pressure to the rims rather than the hub, because of the risk of the spokes distorting, perhaps permanently, particularly with larger wheels. I do remember breaking th...

I built one of these two years ago from a kit bought (when the company was Jidenco) about 30 years prior to that (which must be some sort of record for things kept in the roud tuit box). When I say "built from a kit" I really meant, as others have reported, that it was loosely based upon t...

Re: Driving wheel axle material

It's best to cut the tube before assembling the axles. Also it is a good idea to make the inner rod slightly shorter than the axles, so if you have to trim the axle lengths your are only cutting the tube. You have to do this if you harden the rods, since there is no easy way of trimming them. Yes b...

Re: Driving wheel axle material

I am pleased to hear that you managed to get these materials to work together, Paul. Can I ask, when using the tube and rod from Eileen's, how you cut the tube after assembling it onto the rod? I ask because my own experiments have been complete failures. I attempted to cut the first one on the lath...
