13. Clear your work area and your escape path of brush, vines, and other hazards that can trip you or catch your saw.
14. Escape from the bullseye when the tree tips. 90% of accidents happen within 12 feet of the stump. Go more than 15 feet, and stay out of the bullseye until things stop falling.
15. Keep spectators away more than twice the height of the tree in the direction it will fall.
16. Don't cut alone.
17. Keep your body and the swamper's out of the line of the bar in case of a kickback.
18. Set the brake when taking over two steps or when moving through tripping hazards. Keep your trigger finger off of the throttle when you are moving.
19. DO NOT operate a chainsaw from a ladder! Operating with your feet off the ground requires special training.
20. Do not cut above your shoulders.
21. Springpoles must be shaved on the inside of the apex between the ascending and descending sides. If the apex is higher than you shoulders, stand under the springpole and cut it low on the descending side. It will release upward, away from you.Leaning and heavily loaded poles that are too small to bore cut for a hinge should be shaved on the compressed side until they fold.
22. Do not cut a tree that is holding up a lodged tree. Do not work under a lodged tree. Think about a mouse trying to steal the cheese out of a trap.
23. Instruct your swampers and helpers to NEVER approach you from behind or the sides to within the reach of your saw when you are cutting. If you pull out of a cut with the chain running, or have a severe kickback, the swamper can be killed if he is coming up behind you!
24!! Quit When You Are Tired!

Years ago I seem to remember seeing "conversion kits" to make small gas engines run on steam. It seems to me it would not work well, but... Have you ever seen such a thing?

A fellow student from my hometown converted a Briggs engine when he was in the ninth grade. The major change was building up two extra lobes on the camshaft so the intake and exhaust opened every revolution. It ran well on compressed air. He did it himself in his dad's workshop. He was one of those quiet genuiuses that is ignored by everyone else as they go through school. He does refrigeration and electrical work all over southeast Iowa.
I suspected that steam would cause big problems with washing the lube out of the cylinder walls, but there SHOULD be a way to inject some.

The little brass thing he was adding oil to is a displacement lubricator. Steam condenses, falls to the bottom, and oil floats out to the steam chest. Steam engines originally used tallow to lube the cylinder, but tallow wouldn't stand up to high pressure steam. Some bright person tried mixing tallow with mineral oil, and Voila!!!, Steam Cylinder Oil was invented. That is what is still used today, so the oil mixes with the steam and keeps the cylinder, piston, and rings slick. As water drips out of the petcocks it is a milky color because the steam cylinder oil is emulsified in the water.
OK, thanks for the info. It seemed that someone smarter than me had figured it out a long time ago, but I just couldn't see how it would work in a converted gas engine.

It would be a problem in a closed crankcase system, and I don't know how that is handled. If the crankcase were kept hot, then the water that slips past the rings would evaporate out. I am guessing that the bearings were lubed with a total loss system even in closed crank cases to avoid having water contaminate the lube oil for the bearings. Anyone with experience, please jump in!
