We had a table that looked like that once...then the kids beat merry hell out of it with the cutlery. The eldest one called it 'patina' and I got the blame for teaching him such words...;)

p.s. Full marks for the eldest having the vocabulary to use "patina"!!

I'm now building all my kits with S7 wheels and I thought I'd have a go at adding sprung suspension to some Parkside kits.

I used slaters hornblock springs, cut in half and attached to the back of the axle box by a rod of Plastruct to hold the spring place.

The wagon will need a little weight to get the ride height better as its high at the moment, but not by much.

I just built a track jig. Not quite a rip off from the ones I've seen here thanks Martyn (3 Link) and Graham (Dog Star) :thumbs: ,but there are only so many ways you can do something!!

I'm not sure of the sleeper spacings as yet, but I want flexibility anyway so think I'll make the comb between the sleepers adjustable or removable or I was considering double sided tape and sticking down photo copies of the spacing and positioning by eye and a small square.

I've made it long enough to accommodate the scale 71" long rails that I have.

To use it, lay out the sleepers and thread on the chairs (making sure the keys are facing the right way ;) ) and gauge off rail butted up to the pins.

Like the springing idea Phil :)..........funnily enough I was looking at one of my Parkside Grampus the other day & wondering about doing something similar with piano wire maybe ?

I have been detailing my Parcels to get them ready for painting as my build run is near complete. So have added rain strips and rivets to the roofs of three of them.

Apologies for dodgy iphone photo.IMG_0655.JPG

My method for the rivet detail; is measure up and drill small holes, but not all the way through the plastic. Drop in plastic rod of the appropriate size. Allow a small amount of overlength. I've used 0.55 plastic rod as that closely matches the rivets on the parkside kits.

Brush over plastic weld and leave to fully harden before then triming/filing to size. I then brush over again with the plastic weld to soften the edges and give the rivets a more of a rounded look.

Sorry that this is going OT again, (a bit late catching up on this thread:oops: ) but Calvin & Hobbes is my all-time favourite cartoon as well; I have all the books... and these days have a kid very very nearly just like Calvin.... :confused: :rolleyes: ... at least he's not 6 any more...

Phill, I had to do something slightly different to add springing to the Grampus.

I'm pleased with the results though. Just need to work out how to hide the weight in an empty wagon.

Phil,
There is an alternative way of springing Parkside wagons, using a piece of bent wire, bent as below (blobs mark fixing points):
Alternative spring.jpg

Re the weight, there are two options. One is a thin sheet of lead over the floor - if any detail is required, then the lead can be scribed/embossed, the other is to put the weight below the floor, between the frame members. There is plenty of space between the various underframe members for this.

Hope this helps,

Simon

One question for Simon. In the method you described above where you say use bent wire would any type of wire be useful? I ask as I can acquire various offcuts of 'locking wire' which is extremely strong and flexible, so I was going to nip into our workshops and see what could be salvaged from the waste metal bins,

Hi Mark,
Well, beyond it being springy, and having enough strength, then anything will do: the idea is to experiment and find something which you like working with and which does the job. Guitar strings are pretty useful.

Isn't that just going to apply additional rotational forces onto the axlebox? I can see that it would work, but would rotate the axlebox in the axleguards as the spring compressed - I don't think 7mm scale suspension really needs friction damping ;)

Do the maths, and come back and tell us how much impact it would actually have.
Or, like the rest of us, get on with a pragmatic, practical approach to modelling.

Other spring shapes, which may not have this effect but are a lot more hassle, are also available.

Maths was never my strong point, so I'll have to defer to your superior knowledge. It's almost certainly nothing that a few extra grammes of lead wouldn't cure, which is a fairly pragmatic approach, I guess...

My point was, Martin, that if you did the maths, it won't make much, if any, practical difference - and if a coil spring is even slightly off-centre or over compressed, it will create the same forces.
This is also a quiet way of admitting that I haven't done that sort of maths for nearly 30 years!

The point is, it has been tried, tested, and it works: why question it with "theoretical" objections, especially if you don't have the inclination to learn how to prove your point.
