1/16 round gravers in square brass tube,

John B. · Sep 20, 2016

Monk was kind enough to mention these little gravers in his effort to help Jonathan with his depth control.
Just to clarify. All the info. on making these gravers is in the Tips Archive.
Please note that the brass tube needs to be full of metal, soldered or JB Welded in.
If you use a 1/16 inch cobalt jobbers length drill you can put the flute section inside the brass and solder or JB weld.
I you use a 1/16 dental bur fill the tube behind it with a piece if 1/16 inch brass or steel rod, soldered or JB'd to avoid having the tubing collapse from down pressure on the graver.

I'm having trouble finding the square brass tubing.

A search for 3/32" square brass tubing brought back 1,390,000 + hits.

What you want is in the first half dozen...

Todd, Sources for the brass tubing were mentioned in the original posting which is now in the Tips Archive.
As quite a bit of time has passed there may be some changes.
Last I ordered was from Micro Mark and also Hobby Lobby.
The manufacturer is K&S Engineering, Chicago, IL, Stock #1503.
I'm sure a search for them and a phone call will give you the name of a supplier in your area.
Best of luck with your search and you might post your results for others looking for the tubing.

With the advent of .125 round QC holders, and the problem they solve by not having to ever re-index the graver for sharpening, I ordered some .125 round brass tubing that has an id of .061. 1/16 carbide or cobalt rod should fit in quite nice perhaps after a touch of emery cloth. The walls of this tubing are thicker than the 3/32" square tubing. Thanks for the tip John, and I look forward to making a few of these mini gravers.

Thank you Jonathans.
That should work OK for the folks that have the Quick Change sharpener holder.
People using other sharpening holders or methods may still like to use the square tube for indexing.
Best, John.

forget superglue. quick, but after awhile, at least on brass, will fail when least expected. i never tried the jb stuff.

you migt want to insert steel or copper rod, .062 in the rear of the tube. this will prevent the tube deforming when tightening the screw.

tolesh,
Type in '1/16 inch gravers" in the white search box.
There are two threads by me on page #5 near the bottom.
Hope this helps.

Hi Guys,
I have made many of these but with SS round Tube.
I buy 1/16" carbide rod (micrograin is the best). (2-3") (ebay best price)
go to hardware store that stocks K&S Stainless steel tube (3/32 with a 1/16" hole in it.)
I also use Locktite Bearing setting glue (Red for locking bearing races).
Clean tube and carbide Locktite them together and place them standing up in clay for 24-48 hours.
A light crimp on the tube (graver end).doesn't hert.
Put the carbide in full length of the tube.
when dry grind a flat on the tube and use the flat as 0 degrees (or 180) for your grinding.
these make Super detail gravers..
Your results may vary..
PS: I final polish with Black arkansas extra fine stone with mineral oil (2-4 strokes) (stone is about 10,000 grit).
