Clarkson 24mm x 38mm Vertical

[JasonBModerator @jasonb]

Another one squeezed in before the end of the year. This time it’s a metric version of the smaller Clarkson vertical which gives a bore of 24mm and stroke of 38mm and like the horizontal I did a few months ago I have sleeved the flywheel upto 114mm dia. Blackgates should be able to supply copies of my metric drawings some time in the new year along with the casting set for those that prefer to work in metric and have better and complete drawings to work from.

I quite like the lines of this engine, it is taller and generally of lighter lines than the similarly sizes Stuart No7 which is quite stocky. The longer stroke allows a nice slow tickover for display yet it has a good turn of speed and the thumb on the flywheel tests suggests some reasonable power.
