Harold Hall's precision grinding table

<< < (4/15) > >>

Bernd:
Bob,

Very nice job.

That 4 facet drill sharpener is on my list of tooling needed.

HI
looks good, I must make the drill sharpener thingie for mine.

Harolds dividing head is really good too, I've got one, I'll post some pics if I can find the camera.

Roy,

Thanks Bernd, Roy.  The drill bit attachment works very well.  It was cumbersome to set up at first, but with a little practice, it goes quickly.

It was encouraging enough that I want to do the endmill attachment too, eventually.  It should do a good job on 2 flute mills.

Need to do a guard on the wheel.  The guard that came with the grinder interfered too much with the table.  So either modify it or make a new one.

Hi
heres my attempt at Mr Halls dividing head.



simple dividing


compound



If you get his book' dividing' there is a chart in there that tells you all the divisions possible with three gears.

Roy



thanks to Photobucket for pics.

Roy:  That's the one I want to do.  A friend of mine has a #2 Morse Taper ream.  Try that on the spindle.  Yours turned out great.  The pictures answer a lot of questions.

Thanks, Bob
