Slitting Saw Arbor and Marking Gauge

[rherrell]

No, I haven't designed some wild slitting saw that doubles as a marking gauge.:biggrin:

If you have a mini mill then you probably have one of these...

It's one of those Chinese, spring loaded multi-size hole arbors. If you've used one you know that it's a POS. I got tired of my saw wobbling so I made a single size hole arbor from a piece of 1 1/4" drill rod...

Here it is with the 5/16" tommy bar, also made from drill rod...

I FINALLY have a saw that runs true!:biggrin:

I turned the shaft to 3/4" so I can just put it in my Jacobs chuck, which I hardly ever remove.


Here's a marking gauge that I knocked together. I have several for wood but I do alot of sheet metal work and this works alot better than the one's for wood...

The marking pin is a piece of 1/8" stainless that I sharpened on the bench grinder, it's held in place with an allen set screw.
I milled the top of the rod flat so the brass screw would keep it from rotating.

The body is 3/4" and the rod is 5/16". I made the thumbscrew from 5/8" round brass stock and put some knurling on it.

I hope you enjoy the pics!

I love this stuff. Nothing nicer than functional art. Well done.

Yep you just whipped it up. Saw a need and did it. When I see a need I go stare and my lathe in longing and frustration.

That's what I love about tools, you have the means to make tools that can make other tools! Looks like a lot of fun was spent making these.

I take it, these were made on the new fancy schmancy lathe! :wink:

Would expect nothing less than perfection Mike, an excellent job. When will these be available?
Can't wait till I get a metal lathe.

Rick i'm always amazed by your craftsmanship! Now let me ask, what on earth is that used for? Looks super cool whatever it is.

 

[Justturnin]

Very nice. I have been wanting to get a milling machine to do some playing around but that will be in the ohhh so far future.

 

[rherrell]

Thanks guys!:biggrin:

Seamus, it can be used for just about anything that needs sawing but the thing it's probably used for most is making a clamp....like this...

 

[seamus7227]

this just doesnt help my cause, the more stuff i see like this, the more i realize how much a metal lathe would be an asset in my arsenal o' tools! thanks for sharing rick!

 

[rherrell]

Oh Seamus, it's ALOT wose than you think!! This fits a MILL, that will be the NEXT purchase, AFTER the metal lathe.:biggrin::biggrin::biggrin::wink:

And you guys thought making pens was a money making idea! :rotfl::rotfl::rotfl:

 

[glycerine]

Dang, I coulda used that back when I made my carbide insert tool!

Rick,

I'm admiring your work and the slitting saw is nice. Question - - - - -do you use the slot in the saw to keep it from slipping or just use the set screw to bind it down good and tight?

 

[rherrell]

Ben, I just crank it down good'n'tite, my limited machining skills prevent me from making a keyway.

Too cool Rick. Thanks for posting the great pics.
