Machine tools and stuff...

Indexing/divding head, not rotary table. Is what I was speaking of. Pivot around the bar through the crank bearings to set the top of your crankcase where you want it and shim/clamp the other side. That just looks like a lot of shit stacked up and moveable.

That said, you got it done and didn't kill a bus load of orphan nuns in a fiery crash. I'd call it a win.

I see what you are saying, but I don’t have one of those setups.
I didn’t use a rotary table either, just a boring head.

To organized. Obviously not yours

When I was milling the case I shaved off part of a steel pin. For future reference, magnesium shavings start on fire really easily from sparks. Lol

Very true.

And there is almost no way to put them out

What would be better to get a perfect radius on a manual machine?
Shell mill isn’t really suited for this.

Use the same boring head you cut the case with?

 

[thomas1]

Plus does it have to be perfect? Carbide hole saw/annular cutter?

Where be the machines? all i see is name calling.

Reported.










fag.

Not great for plunging, same issues as the shell mill. Bar would bottom out before cut was through. Would be slower than the shell mill.

OCD makes me want it perfect, big rims need to have tight clearance to not derail.

That's a big mf'er of a piston

Is that where you eat uncontrollably? DSS has that, too.

Why would I want a wedge style vs piston?

I see with the wedge style I’d have to machine the wedge to fit.
Is there by chance that there would be a wedge available for a SB?

That’s the piston style. You want the wedge style.

You don’t machine the wedge. The wedge is what locks the tool holder in place. I’ll grab a pic in a few minutes. The one you linked is a piston style, when you turn the handle on top that round piston, that you can see on the face, is forced out and locks the tool holder in position.

What you may end up having to machine it the T shaped piece that goes in the slot on your compound.

Are the inserts in your shell mill at 90° to the work? Or are you getting a taper from top side of the bar to the bottom side? I’m more used to seeing a shell mill used to remove stock across the top face of a part, as opposed to almost a plunge cut. Maybe I’m just not looking at it correctly.

Huh.... The Ebays says wedge style.

I looked on CDC, what is the difference between AXA and BXA?

That’s what I meant, the Tool Post
I may have to see if I can find a T-post made for a SB

After getting prices from local machine shops to bore a hole in a sprocket from 8mm to 20mm I can’t imagine what they’ll want to charge to mill a little bit off the post
