Bensons Vertical engine
« on: March 25, 2018, 12:40:45 PM »
I recently completed this 1/9 scale Bensons Vertical engine, which is x 1.5 larger than published drawings. Except for the cast flywheel which is from a Stuart Victoria engine all the parts are fabricated or turned from solid bar, the base is aluminium and the column is steel. I could not find commercial helical gears of the right size to drive the governor so had to make them, which proved a lot easier than I had thought, just a case of setting the work at 45deg to the cutter and they meshed nicely.
Of the many peculiar 19th century stationary engines the Bensons engine is a simple yet elegant design, the forked connecting rod dances around the piston rod when in motion. A very enjoyable build.

Great looking engine Mike, can we see it running ?

I've always liked the look of the Benson engine and it is on my to do list for when I have the skills to have a go  :)

that looks great - you did a very nice job of it.

What dia. is the flywheel to give a sense of scale?

Very petty looking engine!  I like the checkerboard tiles you made for the base too!

Mike - That is indeed a very good looking result.
Mcgyver - the Stuart Victoria flywheel used is 7 inches dia.

Thanks for all the kind comments.

Kim, the plinth is made from 12mm MDF and the tile floor is self adhesive dolls house flooring found on e-bay.

Just seen this Mike - must say you have a fine looking model there  :ThumbsUp: A superb result and very eye catching in that green. I agree with you on it's elegant appearance - simple but full of character. I still have a set of enlarged drawings that I did when it first came out - one day eh?

Congratulations on producing such a lovely model

Very nice.  There's something really appealing about these open frame vertical engines.  And... I also feel your pain; I too spend half my time looking for a tool I had in my hand a minute ago  :facepalm:
