What project to do with my grandson?

[Ken I]

Use your car's spare wheel as a reservoir - make up a hose & fitting that depresses the valve when screwed on.

I used to do this for airbrushing before I bought a compressor.

Use an old aqualung or CO2 extinguisher bottle as a reservoir (don't use an LPG cylinder - not high enough pressure rating).

An old fridge compressor might work if the demand / pressure isn't too high - and they are pretty quiet - you can generally pick them up for nothing from a repair shop - they throw lots away.

Run a hose from your shop perhaps ?

Great ideas, keep em coming.
I think an old inner tube might be good, if there are any still around.

OK, please go kindly with the following ignorant question.
On the plans for the Elmer Wobbler engine, several holes are labeled with small letters in a circle next to the hole diameter dimension. They are single or combinations of the following: "C", "B", "F", "P", or "S". What do they mean?

There are 3 drill bit sets in the garage.

1) Fractional set 1/16 thru 1/2 inch in 64th steps
2) Number set #1 - 80 1-60 and 61 - 80 are in seperate case
3) Letter set A - Z

Those letters might be the drill to use. Just guessing, I have not seen the drawings.

Too easy. The holes are marked like this: 1/8 C, or 3/8 CS, Take a look.

C= close fit
S= smooth (ream)
P= press fit
CS= close/smooth (running fit)
B=braze (silver solder)
F=flat (lapped)

Ahhh, that's it!

There's an appendix to Elmer's Engines that calls these out as well as providing some other useful information-- copies should be obtainable from the usual sources.

 

[Mosey]

Thanks ,again.
Would you please give me the link to the appendix to these engines, so I can see what other information there is.
I have assembled all of the stock and will rough cut all of the pieces so that we are ready to go into production upon his arrival at Christmas. I want him to see the whole process from stock to finished running engine, so he understands it all, but not spend the few precious days doing time-consuming drudge work. I have reviewed the plans and have it all mapped out. I might substitute a nice 1/4" stainless shoulder screw that I have laying around for the locating pin.

That link is on the same page where you got the plans. Here it is.

As a matter of fact, if you print off all of the plans and the index and the appendix, you will have the entire book.
