Here I am. Thought (hoping) I had ran away didn't you? The parts are looking sweeeeeeet and Sammi B looks like she is running smooth as a James Taylor song . I think she's definately a " runnah and a keepah. You need to get William a GoPro to use on his RC's and then maybe he would let you borrow it for the shop . I be stopping back by now you heah.

Nice 1 Dave, how powerful is the motor on your lathe? Is it a 3 phase that you are running with an invertor?

[steamer]

Hi Nick

It's a 3/4 HP 3 phase motor, run by a 1/2 hp VFD.   Very controllable.

Dave

[NickG]

They do sound good, unfortunately my harrison was not dual voltage so i would have needed a converter.

[steamer]

My VFD is 110V single phase input, 220 3 phase output.

Very convienent!

Dave

[NickG]

Good stuff, not sure you can get 240 single In 440 3 out? Or maybe you could but they were a lot more i cant remember. Van you run more than one thing from a vfd? There is a possibility i could end up with more 3ph equipment in the future!

Looks like I've been missing all the action Dave. I've got some thread catching up on to do

Dave that is a 1HP VFD that you have.

Thanks Don!

I got the tappet guides set up with their flats   7/16" across the flats....and I got the sensitive drilling attachment done.
Tomorrow, I start on a dummy crankshaft and cam, so I can mount up the various gears. These include the idler, and the oil pump. I still need to bore the cylinder liner bores, and the tappet holes, and then the cross drilling for the oil feed. and then all the threaded holes.

Things will move from there.

Gave old Samantha Bell a good work out this morning!....it's nice to dial in a number and get it...right on the fly do do!

Alright.... time to get the gears located...and get the timing cover done.....so I made up some dummy shafts to be placed where the cam shaft and crank shaft go.   From there I made a toolmakers button to fit the idler...which is the gear between the other two below...and I'll mount that with a screw.




You will notice, there is very little stock left around the cam shaft gear/ timing case....but enough I think to seal against though...but just barely!

Then I started to fit the gear case cover, this had a few lumps inside where the mold had crumbled a bit, so between an end mill and a boring head, I cleaned up the interior to a scribed external line

Again ...not much stock here.


I made a shaft that locates on the crank gear, and locates the bore of the timing case, and checked fit.  I found that the bottom mounting ears are off the sump...so I'll have to re-lay that out and see what can be done....if all else fails, I'll whittle a new gear case cover out of plate.

We progress....I'm extremely happy with my South Bend.    It's everything I hoped it would be!

Nice to see some progress 

Is that a commercial gear I spy 

Jo

[steamer]

Oh Please!
 
My son and I cut all those gears with home made cutters
a while back
The oil pump has commercial gears inside though

It was the colour: it looks like anodising, that threw me 

Edit: Found it: http://www.modelenginemaker.com/index.php/topic,237.msg5967.html#msg5967  that was a long time ago....
