Has anyone else found that you can only sand down the cast frames so far before no more metal is removed and the file switches to polishing?

Yes, I used to - until Justin put me onto using sandpaper (aluminium paper? The green stuff). When it is clogged use a different bit/New sheet.

Then the challenge is applying even pressure across an uneven workpiece to sand it evenly...

Or better still reasonably course wet and dry paper. The white metal dust washes out so clogging isn't such a problem, and anyway it cuts better when wet. Never done a coach bogie side but I did successfully recovered 6 sets of axle box and spring details from a pair of cast tender chassis side frames which included some quite delicate detail.

I put wet and dry on a flat surface and work the metal over it. Taking the piece to the abrasive gives you better control.

On the assumption that this is because the file's teeth are clogged, the answer is a file card brush - cheap, effective and long lasting.

Really like these and so much better than the whitemetal castings.

Possibly, it would depend on the diameter of the Comet 'slab'. It that is less than 13.5mm then it will be fine. Depth shouldn't be an issue.

My thoughts exactly. I find jobs like thinning cast sideframes a right pain and go to great lengths to avoid it! Plastic is easier if you can get hold of something suitable.

Either way there is an asthetic issue with using them on sprung subframes and that is that, in most instances and unless you've removed a lot of material, the bogies will end up looking too wide, especially when planted under a coach. This is probably the only real justification for building a complete bogie kit though it should end up looking better overall.

Having got some to hand, the slabs are 12.75mm diameter and 4 mm deep.

Absolutely right, I should have said that, but I though it was obvious. But then what's obvious to one person ...

Rumney Models - Morton 10' Detailing, Milk Tank Castings

Postby jjnewitt » Tue Apr 02, 2019 10:40 am

Latest News - April 2019

April is upon us already and Scalefour North is just round the corner which means a new round of Rumney Models releases. Due to other demands on my time there is a smaller than usual number of them.

First up is a detailing fret for 10’ Morton brake wagons (B.114 - £4.50). This was done by request and is intended to upgrade Bachmann and Parkside, etc wagons. The fret includes both GWR and RCH brake lever guards along with brake levers, new vees, open wagon door springs (two types), solebar and headstock detailing, lamp irons, coupling hooks and Instanter links. There are sufficient parts for 2 wagons.

Spring and axlebox castings are now available for GWR and LMS milk tanks. These are for milk tanks fitted with oil journals rather than roller bearings. The GWR type is available with either BR or RCH 2 part axleboxes. Note that this variation applies to the outer axles only, the centre axles on all GWR milk tanks fitted with oil journals were an RCH type. All are £5 for a set of 6 and include and etch for the riveted axlebox guide fitted to the outer two axles. For more information and product codes see my website.

A couple of items that were previously withdrawn have been reinstated. LNER steel open stanchions and detailing (B.101 - £3) and the Ratio LMS van strapping and detailing (B.105 - £1). Both of these items will remain in the catalogue until current stock levels are exhausted. Further details can be found here.

As has been noted elsewhere a few kits from the Miscellany Models range created by Mark Tatlow will be available from the Rumney Models exhibition stand at Scalefour North. These are as follows:

Highland Railway/LMS/BR diagram 51 full brake (£48)
Fully sprung Fox coach bogies (£16 per pair)
MR/LMS/BR: Diagram 530 passenger brake (£36)
NER/LNER/BR: Diagram P7 hopper wagon detailing etch (£13.50 - sufficient for 2 wagons)

Please note that I will not be supplying these kits mail order, they are ONLY available from Rumney Models at the exhibitions I’m attending. All mail order and general product enquiries should be directed to Mark and you should visit the Miscellany Models website for contact details and further information on the kits.

And finally a quick mention of a couple of items that will see the light of day in the autumn round of releases. Work on the complete BR Mk1 bogie kit has been completed; samples for the castings approved and the production mould ordered, leaving just the instructions left to write. They won’t be of any use to those who need rakes of the things (likely cost and the amount of time needed to build them would count against that) but if you only need a few and want a fully sprung bogie that isn’t too wide and looks the part then they may be of interest.

Also scheduled for release is a sprung subframe for 8’6” Gresley coach bogies. I have yet to determine prices for both of these items.

I look forward to seeing some of you in Wakefield.
