BTW - electronic level/protractor

[Bob Engelhardt]

I can see that - I'll have to check mine. Thanks. Too bad I never read any those textbooks 🙂...

That's Stefan territory (1 micron per meter)!...

[Bob Engelhardt]

You assumed that I have angle blocks which I do not. And even if I had them I would used the electronic protractor for its ease of use....

[Bob Engelhardt]

You mean the display resolution is coarse? If so, 0.1* is fine enough for me, but YMMV, of course. A bubble level's resolution is all in the user's eye:...

[Bob Engelhardt]

You assume too much....

[Bob Engelhardt]

They claim 0.1* (6 minutes) or 0.2* (12 minutes), depending. https://www.kleintools.com/catalog/l...Specifications...

"BTW" -> not OT, but not a full-blown topic either

I got one of these electronic level/protractors a few months ago on a whim...

This thread started with my query about using square stock for a fly cutter. But it evolved into a discussion of many things fly-cutter'y. And was so...

[Bob Engelhardt]

OK ... I made it. I did offset the arbor to get more steel behind the cutter, per BCRider's suggestion. I intended to offset it 0.125 (3mm) to have...

That's the feed? You feed at 5 tenths?? Surely you mean .010 & .005. Even if that I'm surprised that you got a bad finish with .010 - that's not very...

[Bob Engelhardt]

Oh yeah - it'll rotate 360*. In the pics it was configured for moving....

I am so impressed with the OP's freehand grinding of his form tool that I checked it out. I loaded the pic into CAD and drew a 3-point arc (red):...

I was going to make a cutter whose cutting radius was adjustable. I just assumed that would be desirable. But is it?...

[Bob Engelhardt]

yeah, it's in tune with the mill size itself: it's a Rusnok head, 1/4(!)hp.



It does run both directions. But I'm thinking...

[Bob Engelhardt]

What you missed is what I didn't say 😁 My spindle takes a type Y double angle collet. They're small - the largest is 1/2" & the closing...

Re: rotation - yes, I'm showing the tool end. And I meant the lower left corner to be the cutting edge. So CW rotation.

The 1/4" wall...

I'm going to make a fly cutter and I have 1-1/2" (40mm) square stock and my largest round stock is 1-1/4" (30mm). Bigger is better & the...

[Bob Engelhardt]

Nice & nice form tool - how did you make that?

[Bob Engelhardt]

Nice work & now that it's done you're probably not in the mood for suggestions on how else to do it, but ...

I like the drawer idea....
