Adrian W's 4mm Workbench - Grampus wagons

[Nickey Line]

As a number of people (well, one or two..) have shown interest in this project, I thought I'd start a workbench topic to cover it, and possibly further 4mm stuff.

 

So, the concept was (and I find that although arrived at independently, I was by no means the first) to use the Dapol unpainted Grampus body (very cheap) on the Parkside PA10 chassis kit, plus replacement buffers from Lanarkshire Models, and steps fettled up from an etch for HEA/MEA/MFA wagons from Stenson Models.

I later discovered that Rumney Models do an etch for detailing the Parkside kit which includes the steps, but at £3.50 per wagon I felt that this was going a bit too far. The etch from Stenson Models has enough steps for 8 wagons at the same price...

 

So here's most of the bits before starting...

 

 

First job is to prepare the headstocks to take the replacement buffers.

The existing mouldings are carefully drilled out 1mm. Care needs to be taken to ensure the holes are central top to bottom, and that the headstock is not distorted, as it's quite thin at the ends.

 

 

The buffer bases then need to be filed off, and the guide holes drilled out to 2mm to take the new buffers.

 

 

Again, extreme care needs to b taken! The new buffers are not attached in this view, just posed.

 

I shall be springing the buffers, so the next job is to saw off the heads...

 

 

...and drill CAREFULLY 1mm to a depth of 6mm, trying to keep central.

 

 

Finally drill through the last bit 0.5mm, again very carefully.

 

 

You should end up with something like this...

 

 

Three more to do and that will be enough for now.

The buffers are available pre-drilled, but at a price, so being a cheap-skate I prefer to do it myself!

That's as maybe, but that sort of attitude doesn't put petrol in Dave's Rolls Royce, or even his Land Rover come to think of it!

Maybe not, but it keeps petrol in MY car... It's up to me how I spend MY money.. and these were by no means the only things I bought from him. How many users on this site buy anything at all from LMS???

And besides, I quite enjoy the challenge.

Interested in these buffers, maybe something I could consider for my coaches......

There's a good range of coach buffers, but by no means comprehensive. Much greater range of wagon buffers.

Loco lamps etc. are nice too, a much better size than some available.

Normally I'd be out on my bike on a Tuesday but as I've picked up a sore throat from somewhere there's more time for modelling...

First job today is to tidy up the headstocks and fit the buffers...

 

 

The Dapol body requires a little modification. There are a couple of clips to which the underframe would normally attach. These can be removed. Additionally, some of the door springs are situated well inboard, and would interfere with the fitting of the solebars, so they can be removed and reattached (with a little modification) to the solebars themselves.

 

Body pre-modification...

 

 

...and after. I hope you can see that several door springs have been left intact, as these ones are situated further out, and therefore don't interfere with mounting the solebars.

 

 

The door springs are quite thick, about a mm, so I thinned them down on the back so that they fit neatly between the flanges of the solebars.

 

 

From this you should be able to spot that I've filed down the backs of the solebars at each end for several mm. This is to clear the shanks of the buffers, which would otherwise require cutting down.

Filing down the solebars is the better option, as they're quite thick, and shortening the shanks on the buffers doesn't leave much metal between the end of the shank and the main bore.

I've also removed one of the smaller 'V' hangers (not required) and fitted bearings.

 

Might fit headstocks and solebars this evening, or maybe tomorrow...

Got several of these bodies to do my self . Following this one with interest as i'm a bit partial to the old Grampus wagons.

On with the build...

 

 

Headstocks and solebars now fitted. The solebars needed trimming approx. 0.5mm each end.

From this next pic you should be able to make out the clearance for the buffers behind the solebars.

This was only necessary because I'm springing the buffers.

 

 

Next job is to fit the brake gear, remembering as always to check, double check and check again that you have the push rods the right way round!

 

 

Though difficult to see in this shot, I've drilled through the V hangers and brake gear to fit a brass wire cross-shaft.

 

I'll be tackling the end footsteps next...

Wouldn't it be easier to drill 0.5mm. right through first, and then drill 1mm. to a depth of 6mm.?

 

That way, the smaller hole would act as a pilot for the larger drill, thereby improving accuracy and making drilling the larger hole much easier.

Good thread Adrian, thanks for the step by step photo's.

Drilling right through with a 0.5mm drill without breaking the bit is very difficult. I find it easier to do it this way. Actually, as the 1mm drill leaves a dimple in the bottom of the hole, it acts as a pilot for the smaller drill, and it's only a short way left to go. Accuracy seems to be perfectly adequate.

Other opinions are available.

It took me a while to find a way of producing suitable footsteps. I first tried building one entirely from scrap etch, but it was incredibly fiddly and time consuming.

A post from Fat Controller (thank you Brian!) pointed me in he direction of etches produced by Stenson Models, and I found these...

 

 

...whilst not specifically Grampus footsteps they would do as a basis. There's sufficient for 8 wagons on the etch. I'm currently building 4.

I later found that a another etch producer (Rumney Models) does a super-detailing kit for the Parkside Grampus, which includes the footsteps along with etched door springs and under-chassis storage baskets etc. which I didn't need, but thought should be mentioned here for reference.

 

So anyway...

 

 

The fixing tab at the top of each step is in two parts, which for my purposes is unnecessary, so I removed the top part, then folded the remaining tab carefully through 180 degrees, then folded it over again, so that the tab was protruding from the middle of a triple layer of etch. This not only reduces the length to something close to prototype (close enough...) but makes the mounting point much stronger, especially after soldering it up solid. The tab can be trimmed back, otherwise it will be visible behind the headstock, in front of the solebar.

 

 

I used some bits of scrap etch to make up the raised sides of the steps.

Easier to deal with when over-length, I trimmed them back after soldering up. I've also put a radius on the outer, visible part of the tab, in an attempt to get a bit closer to the prototype.

 

 

This is what I ended up with. Though not entirely accurate (!) I'm happy with them. On the prototype the struts were made of angle, but this is not usually noticeable from normal viewing angles. The steps were also often quite badly bent and battered anyway.

 

 

There's a slot to the right hand end of the headstock where the tab fits nicely. Once super-glued in place, the steps were bent to shape. I think you can make out the shape from the final pic. A shallow 'S' bend.

 

That's pretty much it. I have two more to build but I'm currently short of bearings. I might paint the first two up before building the next ones; either way I'll post a pic on here when I've a completed one to show.

[Nickey Line]

As promised, here's a pic of the first two, posed on my still-incomplete-but-functioning shunting plank!

 

 

Will add loads (probably permanent, for extra weight) and a little weathering. The lettering on these wagons, if Paul Bartlett's website is anything to go by (and I'm sure it is!) was extremely variable, so I've kept to the basics, though some overhead warning flashes probably wouldn't go amiss.

They're by no means perfect but I'm quite happy with them.

That's all folks...
