Holy crap! How small is that thing!?

 

[CarPlayLB]

Speechless! I thought my Ruttman was small! Amazing work Steve! Thanks again for sharing!

 

[Havasu Dave]

Thanks for the update Steve. One of my favorite threads on here.

If my ruttman was that small I wouldn't of had to leave it at rays. Lol. Amazing work. Markus is gonna want one for his showcase.

See if this helps.

Sorry, I have actually read through this amazing thread quite a few times, so I know how small it is... but it still surprises me every time I see it! This build is truly amazing and your skills are top-shelf

I have made a prototype side cover. There are a few things that I am not happy with but the Gcode has been updated and I should be able to make 2 nice ones tomorrow.

Man, that thing looks about spot-on to me. What sort of material are you going to use for the crank?

I use 1144SP steel for my crankshafts. Camshaft will be O-1 drill rod.

Man, I am just in awe.

Some progress today!

I started with a piece of 1/4 inch plate and machined the back side so that when the part is complete the back would have a nice finish for paint.

Into the vise with the good side down the inside is machined out and the mounting holes drilled.

I call it a fixture but it's just flat stock with 2 holes drilled and tapped. The part is bolted to it for machining.

The outside profile is then cut

On the same piece of material a second fixture is made. 2 holes and a pocket to clear the piece so the rear can be accessed.

Then some small cuts are made to fonish the back.

Still needs a few details but it's 95% done.

Managed to squeeze this in before rebuilding the bath tub faucet and painting 3 bedrooms. The original engine had a magneto triggered by a magnet on the flywheel. I am going to go with the CDI board. The bracket in the photo will hold the hall sensor and give me a little bit of adjustment.

 

[capguncowboy]

good call on the CDI board. I bet a points system would be pretty difficult to tune on something so tiny. .035 btdc would tune in to ~.006 btdc. Then thousandths of an inch become more crucial than ever.

My god that is amazing.
