Easy angle positioning in your vice

I have not seen this, not sure if this method is used:

After I made a few fixed angle plates to help in positioning a piece in the milling vice to mill off at certain angle, a new idea stricked me as I was looking at a flat 10m roundbar piece of metal.
-I decided to grind it off in two halves. I then clamped them in the vice and milled them identical halves.
-I then used one half, place it in the vice with the round downwards resting in the vice inner side(Size will be determined by your vice size). I then place a flat 20mm square piece of metal on top of it ready to clamp in vice. Using an anle finder on top of it, I can now find the desired angle(Like 11 degrees) ver easily by using the half circle as a bearing surface(Reference) in the vice, set it easily to 11 degrees, and clamp it. The piece you want to clamp at angle without this you need three hands to clamp it.
-I needed this to make a new Lathe Toolholder for an insert I got.
-Just thought this is an infinite more flexable usage than fixed made angle blocks.

What do you think, any opinions on idea-?

Sounds useful, maybe use a vice stop to help stop it sliding sideways.. ..or some little n/d magnets to hold it place against the fixed jaw..?

Thanks for the idea, I will be investigating further..

Sorry, I think I can visualise it - but any chance of a quick sketch or a photo?

Or photos?

Not quite the same but there is an old system of making a sub-plate where you make a flat on eg a 4in round bar and screw one end of a flat plate to it. Then hold the round bit in the vice at the required angle, preferably with packing under the far end for which certain styles of vice are better than others. Attach workpiece to sub-plate. Not for very heavy cuts.

I have taken photos, many power failures will post it as I can.

Looking forward to seeing the photos. I couldn't resist this little 3" vise as soon as I saw it on ebay, currently in use making special indexable boring bars for the mill boring head. It has two rotational axes, one each side of the tilt which is just right for making small pockets for inserts with sides angled to fit them exactly. Only accurate to about 1/2 degree in any of the three movements, but good enough for my purposes.

Adding photos....If you want to achive high precission, it will take more effort, but for me this is mostly good enough. I added fixed blocks I made for comparison. In this case it does not influnce your clamping itself, using lowest point in vice not angled itself.

Sorry I can't see any advantage to the 'lightly clamp part in vice and tap to suit method' that I use, just my opinion.

I do not have the gap in the base of either of my milling vices, so no good for me.

I do like the handles, the thickness of the paint might be troublesome. Being able to support the workpiece as the vise is tightened up is a good idea. Iuse one of those digital inclinometers and find it very useful. Its resolution is 1/20 degree which is not bad for a cheap item from Lidl.

The paint is removed from surfaces that matters, yes about the thickness when you need real thin.

Just have a flat plate with a captive pin that projects both sides. Rest the pin on the tops of the vice jaws to support the plate while you tighten the chuck.

Hmm, maybe that needs more thought...

Well presumably the half round piece stops the piece being drilled from being pushed down under the force of a drill or mill bit?
