I have been taking your magazine for several years and have
enjoyed every issue. Am sending you pictures of some of the things
I have built in the last few years and if you care to print them
you are welcome to. (We sure do see pictures on this page.

The clam is seven inches high when closed and will pick up about
a cup full.

The gas engine is 1-1/4 bore and 1-7/8 stroke. The flywheels are
cut from the solid (6 in. shafting) and all the parts are built up.
Hit and miss governor, of course.

The steamer does not follow any make but was built to run and
look fairly good. I think it does both. It pops at 100 lbs. and
with 2-1/2 bore and 3-1/2 stroke runs very good. Most of the engine
was built up such as the wheel rims being rolled from flat stock,
the hubs machined from shaft, and the spokes then being welded in.
The flywheel was made in a hydraulic press from a piece of one by
six inch steel rounded up, welded, machined, and then the spokes
and hub welded in and then machined all over again. The water wagon
with the home made one arm johnny pump comes in handy too. I built
a lowboy trailer for the engine and water wagon and pull it behind
my VW. Have had it to Wichita last year and to Waukomis and
Calumet, Oklahoma, this year.

Also built the sawmill which works very good, but it is for sale
as it is just a little too large for my engine. It swings a 20 inch
blade.

I am now in the process of building a Corliss engine of 1-3/8
bore and 3 inch stroke. The flywheel is 10 inches in diameter. Will
let you know when I get it done.
