Got a little bit more done
I need some bronze so i can cast the cylinder lower cover
The price of scrap bronze has gone through the roof

Made the lids for the main bearing oil boxes instead
Replaced the cap heads with studs & nuts

Being an enviromentalist i always try to use the waste energy

Blummin' Wimmin!

They can never see the good we've done...... Always find a little niggle, to grumble about!

That's good work well shown, John!

Got a bit more done
Bottom cylinder cover machined

Faced the gland side bored it then made a mandrell

Milled off the middle bit but left a register for the cylinder

I had a lesson in marking out as the hole centers for the colums are very critical

Starting to look like a engine now

Hi
Got a big bit done it is nearly a runner
Time for a fly wheel
I had a 8 inch disc with a hole in it about the size i wanted but a bit thin
A centre boss was turned up on my boxford
The big bit was possible for me to machine but it would have taken a long time
Rob Wilson kindly offerd to rough it out for me on his referbished cub lathe
(Robs idea of roughing out is different from mine) needless to say it turned out perfect.

Time to cut a key way in the crank

The proportions are just right

Could not resist making it spin around
Click the picture

Just a ecentric strap and some linkage should have it running

John

Well done John!

It's a great step forward when parts can be "oscillated".......

Kind regards, Arnold

Hi
Had a good day in the shop
First a bit of casting

Patern for ecentric strap

Nice solid casting

Using body filler to mark out the centre is a great idea (not mine) Any one care to guess who
John

saw · « **Reply #71 on:** September 24, 2011, 05:05:05 PM »

I'll do the same thing

Good work

Stilldrillin · « **Reply #72 on:** September 25, 2011, 02:10:04 AM »

John.
What do they have in the water, "up there"?

You and the "Other Lad" are full of good good ideas, giving great results......

Hi
I managed to bore the exentric casting with out going to big
I cobbled a valve rod together and a temp valve cover
A blast of ar and it trundled in to life
No rings packing or gaskets at all
Valve timing set very near

click the picture

A very happy
John
