Scaleforum - OMSL

In a blatant steal of a title from RMWeb, with Scaleforum 2009 only about a month away, I've started thinking about what I need (or simply would like!) to stock up on. The list so far (and this post will be edited as I go along) is:

- miniature snipe nosed pliers. When I started dismantling the wheelsets and w-irons on the LNWR open that I'm repairing, I wanted to twist back the lugs on the rocking w-iron, and found that I didn't have a precise way of doing it. In the end I used a pair of flat-ended pliers, but I need a proper tool to enable me to work with more precision.

- a w-iron spacing jig. One of these, in fact - as I found that the Bill Bedford gauge that I have works perfectly for setting up parallel axles, but doesn't work at all when checking already-fitted pinpoint axles.

- wagon wheels. I've just realised how many unmade wagon kits I have, and how many sets of wheels they will need. Alan Gibson will do remarkably good business off me...

- waisted pin-points. If I need the wheels, I need the bearings as well, and these type might mean that you have to junk the ones that arrive with some wheels or in kits, but they are sooooo much easier to use than filing or drilling big chunks out of the back of an axlebox.

More on this post in future as I think of other things to add :-)

The Restoration Chronicles - Squaring up

Time to illustrate the progress so far. The picture below shows the transverse spacer .bar that I've put in to hold apart the two sides, and one of the slivers of plastic strip that I've inserted between the lead flashing and the wagon side. There is one on the nearer side as well - it is obvious that the Daywat used for sticking the chairs to this lead also dragged in the body planks as well.


In the background is an axle spacing jig from Bill Bedford. An excellent piece of kit, but not suitable for helping solve for problem that I found underneath this wagon. More later on that, and adjustments to both my thinking on this wagon, and rocking W-irons in general in my next post.

Paranoid? Moi?

We've all heard occasional stories of tyres becoming detached from wheel rims in use. Less frequently discussed, but probably more prevalent is the chance of a wheelset moving around on an axle during use. Well, I've decided that I'll try and eliminate that risk.

So after double checking each wheelset with a Scalefour Society gauge, I'm applying a tiny smear of superglue to the join between the back of the spokes and the axle. Hopefully that means that they will stay set in place, and one more variable that can cause problems with consistent running is removed.

The Restoration Chronicles - Brute force and ignorance

Well, it's been a while... The combination of stupidly long hours at work and a couple of scheduled holidays mean that it's been far too long since I did any modelling. After a couple of days riding motorbikes around Cadwell Park in Lincolnshire, I now ache too much to do anything more than a bit of gentle modelling.

The brute force is the way that I finally decided to restore the wagon sides to near-straightness. I have decided that if I try and use heat or more solvents, then I just risk making things worse. So I have slid a knife blade down to separate the sides from the lead flashing that is inside the wagin and provides some weight. After this, I've gently eased the sides out with my fingers, and it seems to have worked. What I will do is put a couple of slivers of plastic card down into the newly created gaps to pack them out, and add a plastic cross-brace across the middle as well. Hopefully this will be sufficient to maintain things in a linear fashion.

And the ignorance? Well, I'm still ignorant about exactly what diagram of LNWR wagon this represents. More fundamentally, when on earth was a Permanent Way Department wagon doing on a Great Eastern branchline in the Herts/Essex borders?

So with that as a thought, and in order to avoid the side-warping effects of Daywat Poly on normal plastic mouldings, I've decided that I'm not going to try and replace the C&L chairs that were previously the load. There are a couple still firmly glued to the floor, but the rest have been levered off the lead flashing and thrown away.

There will be a couple of LNWR wagon sheets used to cover the weights, and the reason why it is traversing Essex? Well, it had a hot box and had to be diverted to the nearest repair shop, which happened to be on the GER. Simple!
