Nice looking piece, building one of my own out of brass for a taig lathe. Swing has me limited to very low profile. :whip:

Cheers Johnny. This is actually my first bit of planned turning, and im pleased with how its going. :) Good luck with yours!

I got to milling this morning. I set up an angle plate on my cross slide and decided to machine it to take my compound clide. :thumbup:

This should help with overall milling on the machine, but by milling the plate to take the compound, it meant I was milling it to take my ball turner too. Bonus!
I drilled pilot holes on the drill press and then mounted the base on the angle and counter sunk the allen head bolts into the base. Easy one this. :headbang:

So then i mounted the turret nice and tight onto the center of the plate, and started milling. Little bit at a time but i found i could get away 1mm cuts at a time. :clap:

I cut a 13mm slot then opened it up to 16mm with a few passes as I had got some 5/8" square bar for my sliding tool. I also put a radius cuter in to take the edges off the slot.

Really pleased so far. Im going to sink the tool tip into the tool column, and possibly make it height adjustible too. I need to get a vice onto my compound now so that I can do the rest of the milling, but its coming along nicely.

Cheers

Bernd:
Very nice work Stot. :thumbup:

Divided he ad:
Yup, very nice indeed :thumbup:

That is looking like a very solid piece of kit :)

A little info that might help?
The tip is IMHO by far the most awkward bit. I know I've said this somewhere (brian is malfunctioning and I can't remember where?) but to make the cut out the right size I drilled and tapped the screw hole first and then fastened the tip upside down to the post squarely (used a counter sunk screw) then scribed around it. Thus giving me the lines to work to when I sunk a slot drill into the centre and finished off the sides with the 3mm end mill! (some of the most nerve racking milling I've done!)

How your going to do it on your lathe will be a very interesting read/watch :nrocks: Looking forward to it :dremel:

Stot:
Welllll.. I Played this part very much by ear, but had an idea of how i wanted to do it. Similar to what you were saying Ralph, but I did the lot on the lathe bypassing the dremmel.

I started off chucking the square bar in the 4 jaw chuck and drilling/tapping a center hole for the hold down screw. Then I mounted a 10mm mill end in the tailstock and milleda 4mm deep hole dead center.

Then I offset the bar .171 @ 45degrees and milled an 8.5 mm hole. flipped the bar over in the chuck and did the same on the opposite corner.

Then offset the bar to .313 from center and milled 4.5mm holes in the same way on the opposing corners.

That was pretty much job done to be honest. The smallest amount of filing to get rid of the burrs and it sat square and tight. :thumbup:

The post was 0.5mm too high so a quick face of the bottom and it is sitting bang on. :) I may make another one later down the line but for now this should work.

Cheers
Stot
