Tiny Super

[Ghosty]

Hi All,
Had a big day today.
I could not get any bronze flat bar, so made some.
Cut a piece of round bar over length, cut of the big end cap piece, faced both and soft soldered together. Set in mill and using a slitting saw I got two pieces for con-rods.
Marked out, then drilled and tapped for big end cap bolts.
Drilled out holes and reamed big and little ends.
Turned up some arbours to hold the con-ron, mounted in mill and machined both ends and sides.
Swapped to lathe and machined both ends, then back to mill to finish the sides.
Drilled and cleaned up the oil holes in both ends of the rod.
Cheers
Andrew

Hi All,
Started on the crank today, cut piece to length, center drilled for crank and big-end center's, mounted in mill and hogged out big end.
Mounted on lathe between center's and machined big end.
Cheers
Andrew

On closer inspection of the articles, the main caption reads "Tiny super", but in the smaller caption box, the name is continued... "Tiny super high speed gasoline engine" which makes a lot more sense, even if it's a bit of a mouth full!

Don't care what it is called, it is not that Tiny to some of the other builds around. It may of been Tiny back in the day thou.

Hi All,
Removed from lathe and re-set to machine crankshaft shafts, had to reset and glue in the crank spacer. Started with the front shaft, then machined the rear rotor/drum, drilled for crank webs and rough machined.
Machined up a jig to hold the crank and mounted in the mill and finished machining of the crank webs.
Removed the crank spacer and cleaned up the machining marks and edges.
Cheers

That's a very nice looking crank, Ghosty! Is that a quad bearing revolving centre you're using? If so, could you remind me of the manufacturer? I've been promising myself one for years!!

I don't know any thing about the revolving centre, I picked it up at a garage sale with a heap of other tools, there was a sticker on it at some stage, because there was the remains of it on it when I got it. Sorry.

Hi All,
Got the rear cover intake done today. machined rear cover, lapped in the crank, then machined outer part/intake of the cover in mill.
Set up crank and machined intake port.
Fitted intake tube to back-plate and checked the assembly.

Hi All,
Easy day today, went with electronic ign, machined up the pickup ring and prop driver, mounted prop driver and spot drilled the crank for the set screws to lock to the crank, made up a mounting plate, and ready to go.
Mounted on test stand and run, played around with the timing and mixture settings..
Got it running steady and consistent.
If anyone knows of any other OLD engine plans like this, could you let me know, always looking for them.
This is the end of the build.
Cheers
Andrew

Andrew,

That is awesome, congratulations. The sound is beautiful and brings back happy memories of when I was a kid flying model airplanes.

Did you find the drawings?

 

[methuselah1]

I must congratulate you! Quite a kick when you get an engine going.

Now, if you want more old plans, and if you look hard enough, the Motor Boys International were all about re-creating old engines, usually without castings, and many if these have appeared on the net. They're often single cylinder sparkers.

Another option is to look at Hemingway Kits in the UK. They sell drawings and castings for several Westbury engines. E.T.Westbury was a tether boat racer back when a chap had to build his own power plant, and his designs were coming out from the 1930s to the 60s.

I think another worthwhile avenue of enquiry might be O.B.(?)Winters in Oz.
