SEL 1560 Steam Launch Unit


The 1560 was the odd one out of the SEL range for several reasons. Firstly, it was an engine unit on it's own with no boiler etc. Secondly, it was a completely different design of cylinder, much larger in size. It was designed to be fitted into a model boat, along with a boiler from elsewhere. SEL never supplied a suitable boat hull or any model containing this engine under their own name (to my knowledge). However, it was supplied on an OEM basis to Mamod to be fitted into their ME3, complete with Mamod boiler. (see here)

It has a 7/16"diameter cylinder with a 1/2" stroke. The flywheel is only 15/16" diameter but is still quite heavy being 5/8" thick solid brass. The whole is mounted in a substantial solid brass frame and is not inclined. In this form, the output shaft is plain with no fittings.

This example, as purchased, was mounted on a wooden base, which didn't do it justice. I have removed it and fitted a pair of aluminium bars to support it.

Since writing the above, the paint started flaking badly. I'm not sure if this was the original paint, but it began to lookquite bad. I, therefore, decided to repaint it and, give the brass a good polish. This condition is shown in the photos.

The bottom picture on the left is taken from SEL's catalogue. The following is also quoted from there:
