Book of plans for small internal combustion and steam engines

Actually making your own cutters is not that difficult. I have used the cutters made according to:

http://www.helicron.net/workshop/gearcutting/involute-gears/
http://www.metallmodellbau.de/GEAR-CUTTING.php

They work well and there is only minor material costs and some time. A cheap spin indexer for about $50 works well for indexing as long as the number of teeth is in 1° increment, no .5° increment etc.

I've made different indexing plates for the spin index so there isn't even that restriction.

I have also done that. I finally got a set of cheap <$35 index plates for my rotary table so that is what I use now. I have even made some weird DP gears. I had a situation where I wanted a 1:10 ratio in a given space and made gears to fit that. Worked jut fine.

I'm looking for a good book of plans to build small bore (-1") steam and /or gasoline engines. This is going to be a Christmas gift from myself to myself. I don't want a book of "basic" plans, as I have these books and have built any number of small engines. Not looking for train plans, I want stationary engines. I've tried googling what I want, but Google has become so loaded down with crap that I can't find anything. All suggestions are welcome.----Brian

Have you looked at The Engines of Doug Kelley?

Buy a pair of gears from China. Usually enough there for a spare set as well. Cost maybe $30 delivered and who knows unless you tell them as most are internal anyhow.

Danuzzo,
I have used the technique Gordon linked to make a gear cutter. It works very well.
Check the DP of the Webster gears, I think they may be 32 DP, so if you buy a cutter, you probably want 32 DP.
I have also used the method Philip Duclos describes and it is for a single point cutter which will certainly work, but the multi tooth cutter works better.
