One of those facepalm "why didn't I think of that" things(hvor kjّpte du diamant-skiven?).

I can barely guess what that means based on my very limited swedish skills:

Bought from chinese seller on ebay, 3-disk set was something like 14 euros. 240-600-3000 grits included, the 240 grit cuts carbide like its butter!

Those angle protractor scales are handy for purposes like this, I tack welded ot with TIG on the steel plate.

[KMoffett]

Nice welds. I was told that a master welder can weld tin foil to an anvil. You're getting close.

Forgot that Biltema was in Finland as well....

Now I can continue my aluminium TIG training ....

slitting saw arbor with Aciera W12 mounting:


Maybe I can slit my next collets with proper tool instead of angle grinder

You do not describe in detail how the blade is held to the shaft. My finding is that this design gives the lowest profile. Allows the tool to be used more readily in places where it needs to clear something underneath ... often the milling vice.

That looks like a nice version. Truth to be told I didn't pay any attention to underside clearance. Bit similar system as in your post crossed my mind but I didn't see use for it because I thought that 63mm slitting saw is total overkill for my mill (Aciera F1)
Turns out that 0.5mm blade cuts very easily and on the lowest range I get usable 125rpm speed for HSS.

Clamping on my tool is similar to for example this:

Cool drawing. Do you have a picture of the finished item? Would love to see it.

For smaller saws

For the smaller saws, 40 mm OD with a 12.7 mm ID, I used a countersunk cup head bolt instead. That works very well too.

I did something similar as Norman Bain showed but with a bit more reach. The only downside with Norman and my version is that it requires TWO really perfect fits to be machined to keep the saw blade running as close to true as possible. But as Norman said it has the advantage of being able to locate closer to the jaws of the vise if that is what it's being used for. Getting just the right finger push fit on the parts took a little care but we home shop types have the time for getting it just right. The roughly

This picture shows three of the MT3 items I made up on my lathe. That being the spindle taper on the mid size mill/drill I had at the time. I used an MT5 to MT3 adapter as a tester to sneak up on the fit. The extension on the saw arbor, which is obviously the one on the left, is roughly 3 inches to get a touch more reach from the spindle nose so I could reach down far enough when using a spindexer or my rotary table in vertical mode. The screw is shown only partly screwed in. When fully fitted it fits down into the end cap just as Norman posted on his 3D drawing. The half dozen times I used it I did not find that the extension was an issue with chatter at all. I need to make a similar one up with an R8 shank for the new mill.

"pipe bead roller"

[vpt]

Nice! Are you just spinning it around the pipe by hand?

[Richard T]

MattiJ - Great tool and excellent results. I think I need to make one of those.

Did you turn the male roller with a form tool?

[vpt]

Ah, I see the nut with pin threw it and understand now you turn the nut to turn the small die. Simple, small, and works! Its a win win!


I knurled the male/small die on the one I built so it had a better bite on the tube/pipe. I was getting some slip on stainless tubing.

[MattiJ]

Did you turn the male roller with a form tool?

Just turned to rough shape and 5 minute work with a file to finish.

Vpt: mine has slipping tendency also sometimes but it works with some fiddling.
SS tubing is easier slip vise than alu for some reason.

If I would be making another I think I would try and see 3-wheel design
