Well another installment of the lower crankcase

The Set up......2 hours....I knew I wasn't crazy for buying that vise

The cut.....2 min

Oh man...I actually did it

Outside Done....just some filing of the sharp edges

I might actually build this engine....the fun stuff is yet to come ...crank and camshaft scratch.gif

Looking GREAT Tony!

On your "set up" time....
Machining is 80% Set Up - 10% Cutting - 6% Machine Maintenance
and 4% Clean Up.

I'd say you are right on schedule.

Hey Thanks Rick, :bow:
Yeh, I know, set up is where it all happens. When I was a kid doing wood working with my dad I learned that.
Tony

 

[NOI53Y]

Looking good.

Just from an engineering perspective is that angled/beveled cut necessary or is it more for aesthetics.

 

[cobra428]

Thanks NOI53Y :bow:,
I don't know about the bevel thing to give you an honest answer. It's on the drawing so I put it in. I did find a place that had pics of the real engine.....know what.... in the 5 pics ....there is no view of that. And EW took some "artistic license" with his model.

Wow. Got caught here and had to read the entire thread.
Darn it. Another great thread taking away from my machining time.
Really beautiful work Tony. I hope it's less than 6 months though...for my sake.

 

[cobra428]

Thanks Zee :bow:
Are you talking about the 6 mons EW took to make it? If so, you're looking at a lot longer than that my friend :big:
Tony

 

[cobra428]

[Deanofid]

You've sure made a great start, Tony.
I never thought I'd say this to another guy, but, that sure is a pretty oil pan.
Keep up the good work!

Dean

 

[cobra428]

Deanofid,
Thanks Man, :bow:
I've been wanting to call it an oil pan but I'm afraid I'll confuse the Ozzie's and the Brit's Rof}
Tony

 

[Jones]

What's an oil pan?

That's a nice sump you made there :big:

 

[vlmarshall]
