Reconditioning a Stuart Simplex

<< < (3/8) > >>

Mike R:
I personally like option 2 as I'm not a purist and wouldn't know that its not original to the design, I think it would look more "scale" with 8 studs.
It is also going to be easier to repair as you say.

Jasonb:
I think 8 fixings is overkill for such a small engine, scale does not really come into it as these are 1:1 engines designed for powering pond boats not an attempt to replicate a larger prototype.

One option to keep it looking more original and avoid the old holes would be to use 4 fixings for chest to cylinder placed slightly down and up from what is there now but use CSK screws to retain the chest to the cylinder. Then also tap the 4 corners of the chest for studs to take the cover. That way you are tapping into virgin metal in the cylinder but from the outside it will look like the studs are in the right position.

If you do want to make  a replica at least you have something to measure and they are not too hard to make.

Zephyrin:
wow, this cylinder is in poor condition...
for me, I'll drill the screw holes, and press in a bronze rod soft soldered,  then after a pass under the milling machine to get a nice surface, I'll add a layer of bronze to the top of the cylinder, tin soldered too; then resurface the top of the cylinder and the distribution face.
steam ports need attention too, and this will lead to a new steam valve adapted to the new ports sizes. Yes, it is close to "le couteau de Jeannot", whose either handle or blade are sometimes changed, but always remains Jeannot's Knife.

a new steam chest with thicker sides must be done too with 4 fixing bolts.

Sanjay F:
I like the idea of retaining the look and at the same time ensuring the cylinder is retained solidly - thank you for all your ideas, this why this forum is great!

@Zephyrin - I like the fact that there's an equivalent to 'Triggers Broom'!


Look what just arrived in the post - a valve chest and cover for Trojan; after a quick glance, I think they'll work out okay ...... hopefully

Sanjay F:
Started cylinder repair:

- Filled in old stud holes
- Built up sloping edge so its now level with top of cylinder
- Filled in where studs had broken through edge of cylinder
