Perhaps you guys could help me out with some advice .I finally tried out an old sweetpea which I have been restoring for some time and ran it for the first time at our clubs spring steam up. Unfortunately I was subjected to all the chinney could throw out for most of the journey. I have seen various devices over the years to direct the smoke sideways. Are these gadgets any good ? Are they easy to make? Cheers Gareth

I've seen 'em made from commercial copper elbows. Don't know if they are of much advantage tho' - unless you make 'em unreasonably long.

Gareth,
In my experience it is simply a get used to it sort of solution. If you also haven't some sort of spark arrestor get a hat. It seems to be one of the laws of the universe that lumps of hot n'nasties ejected from the chimney will land on the driver's head and believe me the pain lasts for weeks.
Another solution is to only go out on windy days. This reduces that amount you get in the face a little bit.

Solution 1 is to stick a tea strainer over the chimney. Usually possible to position with some low cunning and some wire.
Solution 2 which is the one I adopt on my unsuperheated Sweet Pea is to get some fine(ish) wire mesh and make a tube of it that goes round the blast pipe and up to the base of the chimney. I wire it in place with copper wire. You still get the oil in the face but no really big robins in the hair or down the neck.
Solution 3 requires an old fizzy drinks can and a jubilee clip. You cut a deflector out of the can and clamp it on with the jubilee clip.

Gareth, The_,
I tried solution 1 but used a standard size sieve mounted on a plug that went down the chimney. Two problems, everyone laughed and took the piss out of me and all the hot n'nasties bounced off and landed on the saddle tank burning little holes in the surface. Maybe a don't use car paint moral here.
I ended up with a version of solution 2. I found a piece of 15mm copper heating pipe slipped nicely over the blast pipe below the blast nozzle and blower ring. To this pipe I silver soldered a piece of brass strip that was wide enough to span the boiler tubes plus about 3/4" both sides. I split the ends and folded them back towards the middle. The split ends simply secured the sides of a piece of stainless gauze big enough to cover the tubes. The top of the gauze just tucked up under the two steam feed pipes.
Solution 2 solved the hot n'nasty problems completely just made it a bit more tricky to clean out after the fun was over. The gauze is easily removed/refitted. for brushing the tubes. It's also invisible so the piss-takes ended.
