This is a good engine build.
I considered purchasing one of those Frisco Standard kits, but considered it a bit too complex for me at this point.
I am designing a single-cylinder Frisco Standard using photos of existing engines, and the original patent drawing for the head.
That head is rather complex to say the least, but they seem to run very well, and it is a nice side shaft design.
I looked at building a Hicks also, and some have been able to acquire Hicks drawings from the Museum in CA, but I have never gotten a response back from the Museum after numerous tries, and so fate has let me to create a Frisco-Standard single (scale 4 hp) design.
In the end, it is working out better that I am making a Frisco-Standard 3D model, since I have come to believe that it is a better engine than a Hicks, and as I mentioned, a very nice side-shaft engine. Hope that does not ignite a Frisco-Standard vs Hicks feud.
Those helical gears were very difficult to figure out, with both being the same diameter, but giving a 2:1 speed ratio.
I got some help from JasonB and friends to solve the gear challenge.
Did you get this engine painted and completed?
