Project Stoopid!

Hack, your shop, and your machining abilities are ( in my opinion ) WAY above the average member on this forum. The guy that built the miniature Ferrari is the only other one I can think of in your league. Keep the pictures coming. Super interesting.

Pancho, thanks but ya are exaggerating...

among the 873 projects in progress right now is my DIY lawn dethacher. The resident wench here has requested the grass here @ MTL needs fixin. that requires a machine.
my inner cheapskate would not authorize a rental, so....
i built one, keeping with tradition only scrap materials and parts are used.
The 12hp vertical shaft flathead briggs didn't want to coperate, however.
l'm still tryin to unnastan why the flywheel key sheared off.
yellow arrow is the mag
red is the piston.
Engines do not run with ignition timing off 90°.
this qualifies as a WTF moment.
back to our regularly scheduled programming soon.

So the keyway on the crankshaft is buggered up from chewing up the key. As an experiment l am trying to go keyless. l need this thing to run a few more hours B4 winter repair season. Dont have time right now to fix it right now.
How well ya think Loctite would work?
l have some #727 and it is some seriously tenacious shyt! l lapped the tapers, cleaned them and applied a film, put the bolt in a torked it down.
So how long ya think it gunna work?
1. a few minutes
2. about an hour
3. all day
4.? what its fixed!
5. til it gets hot.
take yer guess and post it up.

They go keyless flywheels all the time on race engines. Then you have infinite variable timing.
A taper is pretty stout as is for holding. But you know this.

It'll be fine

I'm bettin that they aren't using the same type taper as a 40 year old B&S.
I did take advantage of the situation and advance it a fuzz.
and yeah tapers work, ya see em all over the place.
