Hi All,
I want to remove the tang from the morse taper that holds my drill
chuck in the tail stock. I assume it is hard steel. I have a hacksaw ,
metal cutting band saw and an angle grinder that I could buy a metal
cutting blade for.
An suggestions as the best method ?

John, when I wanted to shorten the tang on mine, I purchased a 3"
Cut-Off Blade with Mandrel. Then I clamped the Taper (with suitable
padding) vertically in my X-Y vise on the drill press table. I
wrapped a wet towel around the Taper, to act as a heat sink, and
placed the Cut-Off Wheel in the drill press chuck. Running the drill
press at slow speed, I fed the vise against it. I was surprised how
easily it cut. After that operation, I dressed up the edge of the cut
in the grinder.

Thanks for the reply. I do have a 3" blade and holder. I forgot I had it until you said!! John - In 7x12minilathe@..., "wardwmiller" <wardmiller@...> wrote:

Most MT's are hardened and neither a hacksaw or bandsaw will touch them. I have cit several using an angle grinder and disc. You need to measure carefully before you cut, if you cut too short you will not be able to ejrct it when you retract the tailstock below "0". To measure wind out the tailstock a couple of inches and mark the taper with a magic marker or tape etc then rewind to eject the MT and then wind down to "0" and measure the depth. THen transfer the measurement to the MT and cut to length. Cut slowly and cool in water so you don't soften the MT and then face up and give a light chamfer with a bench grinder - job done!

It pays to check the hardness before going to a lot of trouble to
shorten the taper - its easy if the taper isn't hardened -- many of
the Chinese tapers are soft.
My chuck and taper were from HF; I used a file to determine that the
taper wasn't hardened. I then took the easy way out, grabbed the drill
chuck in the 3 jaw and used a rolling center in the little hole in the
end of the tang. The parting blade cut part way through easily and I
finished up with a hacksaw while running at low RPM, then smoothed the
end with a file.

Thanks John , I will see how hard it is first , I have found a metal cutting disc for the angle grinder so I might just "attack it" with this anyway. John --- In 7x12minilathe@..., "John" <John@...> wrote:

I have used the thin cutoff disks in a Dremel tool. Cuts hardened
tangs and leaves a fine finish. Soak your disks in atf, they last longer.

Hi John, Some have used a Dremel. I used an angle grinder and cleaned up on the bench grinder. Yes, it's hard. I initially tried a hacksaw but blunted it rather quickly. Get the length right. Cut it too short and you'll have problems ejecting the arbor. John --- In 7x12minilathe@..., "jcmackastro" <jm@...> wrote:

Hi All.
Have just used a hacksaw for shortening an Arbor. Held it in the vice
using the Tang then used six junior hacksaw blades and a lot of
effort!. Used a junior hacksaw as I had plenty of them in stock and
they are cheaper than using a 12" blade. Must buy myself a powered
Hacksaw, the type that takes a normal blade. Finished of on a
grinding wheel. Looks OK.

It only took me about 2mins to cut of the tang. I used a thin 41/2" metal cutting disc that I bought from machine mart. Lots of sparks but it cut it easily. John --- In 7x12minilathe@..., "wireless_paul" <paul@...> wrote:

It is not too difficult to braze a small piece of metal on the end to make up the difference and it does not have to be cosmetic.

The ones I've gotten from Enco are casehardened, but not necessarily
through hardened. If you don't have a big grinder, a Dremel tool with an
abrasive disk works well enough if you're in no hurry.
If you cut it a bit too short, as I did on one once, you can epoxy or
solder a bit of mild steel in the center to build it out again.
