Dave-

What you want is a Lollipop Cutter if you can find one at a reasonable price.

That is a cool tool.  It might be easier to make one of those out of drill rod than to grind a ball end mill to shape.

I'm thinking inexpensive 2 flute and grind it back...I can spend $100+ for a lollipop...and they are available....but kinda pricey

Dave

Sounds like a job for your cutter grinder 

Jo

[steamer]

Yea...but the cutter grinder needs work too ....and I only need to grind it back....for clearance....I'll just do it on the belt sander.

I got a chance to work in the shop and I have the mains roughed to 1/2".  The finished bore diameter is .563"

I have to make up a boring bar to finish it off..  I want to inspect the location of the rough bore as it might be about .010 out of position...but I have a chance to make that right when I bore it to final size.

Here's some progress shots

Brings back memories.

OH and how I did it

I started with a 5/16 2 flute end mill.   I plunged thru the first two bearings, then installed a 5/16 drill and ran it through.

Next, I did the same thing with a 1/2" end mill and then 1/2" drill.

I'll be making up a single point boring bar to finish it all off.

Nice job Dave, I see you are finally making some progress. I am curious about the single point boring bar in how you go about it. Will you be using the lathe or mill?

Don

[steamer]

I've trammed the block in pretty well...my angle plate...which I bought and then scraped flat and square is holding it nicely!   I have to admit that I'm more than a bit chuffed that its working that well.

I think I'll be boring it right where it is on the mill.

Additionally, I'll do the camshaft bore with the same set up...it's there!

Dave

[steamer]

And Don....I'll show you what I mean about the boring bar when I make it up....lots of pictures I promise.

Dave

[Don1966]

Did you like the package I sent.

Don

[steamer]

Yes I did!....
Thanks!

Did you get my email?


Dave

[Don1966]

No I didn't get an email,  that's strange.

Don

[steamer]

 Sent it again.....
