i was at my dads awhile ago and he brought out a box of my junk that has been in storage at his place for the last 20 or more years.
some of the stuff was junk, but there was a few pieces that were ok.
the first piece was this double acting wobbler that i built using some drawings from model engineer.
the drawings were done by edgar westbury back in 1967.



it has a 1/2" bore and stroke (i think)
i used to run this engine with an aquarium air pump, one time it ran for a whole year non stop.
there was some other stuff in the box but i haven't got pics of it yet.
the reason i posted this engine is to see if any of you guys will post pictures of your first or second engines.
i think it would be neat to see some of the first projects people have made.
i have my very first engine that i made when i was 12 years old, i will post some picture of it tomorrow.
