I find these are better than wire brushes, if only because you are less likely to get bits of wire in your eye.

Thanks Bill I will have to go lookking and try those. I agree with you the steel wires can be annoying. They get stuck in the fingers and turn up in the strangest places.

Getting there...

Postby Flymo748 » Thu Jul 16, 2015 9:48 pm

Well, after a lot of scraping of solder, and cutting and hacking, the Calf Van was reduced to a minimum. Every time I thought that I had reached a point of satisfaction, I found another element that I wanted to remove to improve it.

You may have seen the partly rebuilt van over on MikeH's Forum thread about starter wagon kits, where it made a brief appearance.

Now it's finished apart from adding weight and a roof. I assume that the roof was originally etched brass, and included with the kit. However like many casting details, this wasn't with it when I acquired the part-built kit.

So tonight I've been out with ruler and set-square, piercing saw and files, and started cutting out the roof from a piece of sheet brass.

I've started squaring it off, and if I have time tomorrow I'll measure the arc of the roof and mark it out to size. I've already pulled the trusty GW Models rolling bars out of storage, and I expect that the actual rolling of it to shape will be the quickest and simplest thing to do...

Cheers

I cut rooves using a Stanley knife, scoring it deeply then bending. I hold the brass in bending bars to break the piece off which keeps the edge flat. On thicker brass I have scored from both sides. The edges need touching up with a file, but it is quick and straightforward. The drawback is that you have to cut a strip but offcuts are useable elsewhere so waste is minimal.

Something to look out for with the GW bending rollers - while the centre of the roof may be fine, at the edges where there is no continuous support from a second roller the roof curve may not be a steep as it is supposed to be - exactly where sometimes it needs to be.
Consider annealing the roof first then rolling and finish off the edges with a bit of camper mat and a small bar of brass.

Depends of course how thick the brass sheet is. Even using 10 thou this will take some time. An alternative is to us tin snips (scissors for metal) They may put a slight curve on the metal but this can easily be flattened. Safer than using a knife. :)

Thanks David!

That's a really useful tip. In fact, dare I suggest that I can improve on it?

My Stanley knife is down in the motorbike tool chest in the garage, so I had a quick look around. Knowing that a normal modelling scalpel would not be stout enough I chanced upon the scribing cutter that I use for plasticard. It turned out that brass is soft enough for this to work effectively and as well as some really tiny coils of thin brass which I can think of no earthly use, it produced a really clean groove that was easily snap through:

So now I have a lovely square sheet of brass that I can role in the rolling bars very quickly. I think later today I shall be wielding the soldering iron…

Probably an obvious thing to say but...... I always cut a roof from thin card before I reach for the brass to check the overhang looks right. In the past I've cut some too short/long - but that's probably just my bodging style.

Post-it notes.

That tackiness along one edge acts as a very useful third hand when trying to line it all up and mark it accurately.

One thing that I have done on this roof which is not apparent on the prototype is to round off *very* slightly the corners. It may not be strictly accurate, but it does stop me bleeding all over the model at a future date...

I never thought of using a scriber. I think I will stick with the Stanley, though, because the blade does blunten and it is easier to change.

Rounding the corner is a good move. Not doing so makes everything so sticky.

Which made me think that I don't have any spare blades for the scriber/cutter at the moment.

Ten minutes on That Interweb found that they appear to be difficult to obtain from a source in the UK. However thanks to the joys of international commerce, I now should have three packs each of five blades winging their way to me from deepest, darkest Poland...

If they turn out to be what they claim to be, and they turn up (I'm currently receiving a series of apologetic emails from the supplier in China of a 99p part for the strimmer carburettor for the garden...) then it will be a bit of a result for £2.07 per pack, and just over three quid for postage!

I have used this method on 20thou nickel silver which I picked up cheap. I was cutting floors for wagons and scored the metal from both sides with 3 or 4 passes.

I have used the Olfa cutter blades for sheet brass and nickel for years and it is much quicker than using a piercing saw. It is also possible to cut very thin strips, such as for brake levers, without having to uncurl them. I did find that you have to be careful as the sharp edges need cleaning up (I use an emery stick). I have quite a supply of brake levers now, as, having made a few by this method, a good friend cut me a load of levers and safety loops using a Swiss guillotine.

This of course is a much more expensive way than Flymo's internet supplier of the cutter blades...

Philip,
Can you be more specific about the Olfa Cutter - the ones I have seen seem more suitable for paper, card or material. They come in knife form which seem no different intrinsically to a Stanley knife and also in circular form.

Olfa also do what is commonly known in modelling as a "Skrawker", traditionally ground from old hacksaw blades, but Olfa saved us that trouble.

That looks like something you could get in 'used' condition from your friendly dentist.

Indeed... It was a couple of Missendens ago that Tim Watson disposed of quite a few of those to the 4mm Locomotive Building group, in return for a contribution to the charity tin.

I have about three, in different shapes and angles. As they are both incredibly tough, and sharp, I find them very useful for scraping out solder joints, or removing it from panel lines, or whatever.

Make friends with your dentist - it makes sense in many ways!

John,

The Olfa cutter I have is the 'scrawker' shown as no. 3 in Keith's photo. I have two of them now, one I keep for thick plastic sheet and the other I use on metal, simply to preserve the blade on the 'plastic' one. I use that also for scribing plank lines in sheet styrene.

I think they are readily available although I've had mine for many years. I don't change the blades very much as a little fettling with a diamond lap hones the edges up nicely.

Philip

Mine, acquired many years ago, is branded "Tamiya".

It's actually very nicely made and has a really good feel to use. Unfortunately they have changed the design, and the current ones ("Scriber II") seem a little more plasticy and flimsy. That's only the impression from photos and I hasten to add that I haven't tried one in use.

They seem to be widely available online, starting from around a fiver. http://www.ebay.co.uk/itm/like/350806925836?limghlpsr=true&hlpv=2&ops=true&viphx=1&hlpht=true&lpid=108&chn=ps&device=c&rlsatarget=&adtype=pla&crdt=0&ff3=1&ff11=ICEP3.0.0-L&ff12=67&ff13=80&ff14=108&ff19=0 Highly recommended as a purchase.

And last thing last night I popped the roof in place, so this is another thing all ready for the paint shop...

I refer the Honourable Gentleman to my previous answer...

If you are going to start ignoring my declaration of a "three foot rule" for this vehicle, I'll park it permanently in a cattle dock so you can't tell whether I've adjusted them or not ;-)
