Re: Removing Tang From A Morse Taper

 

Hello.
Took me about 2 hours!!
Good exercise?
Removed the tang and about 5mm of main body.

Re: 8x12 is now officially "ON ORDER"

 

Yes, John, you have. But in a good way. It will save me a 2nd order
later. Thanks to others for your input.

I've added:

2644 Clamps for the faceplate
1222 Chuck studs & nuts
1655 Oil fittings
1773 Spare dial springs
2633 Tailstock clamp spring (is this needed on the 8x12?)
2743 Thread gauge
1551 Cutoff tool holder
1929 Cutoff blade (should I order 2?)
1240 Center Finder
1730 Sissor Knurler

I guess I'm holding off on the steady rest & follower rests.

Hi Ken,

Someone (possibly on this forum) had a neat idea after breaking the
tip of a centre drill. They re-ground the thicker remaining stub to
gouge AROUND the broke small tip. This allowed access to get hold of
the broken piece to reverse it out.

Is that viable in this case? Maybe use the stub of an old (broken)
drill bit. Needs to be stumpy and solid. Butcher's technique but may
save a casting.

Re: 8x12 is now officially "ON ORDER"

 

Hi Rance,

After I bought my 7x I placed and order on LMS for accessories.
Being in Oz I tried to include all I could think of to minimise
freight. Nope. I missed things. Just taken delivery of another load.

Apart from obvious items I now have #2644 clamps for the faceplate,
#1222 chuck studs & nuts, #1655 oil fittings for the leadscrew (my
Sieg doesn't come with those), #1773 spare dial springs, #2633
spring to make the tailstock clamp stay put, some pitch gauges and a
protractor for setting the compound.

It pays to check the hardness before going to a lot of trouble to

My chuck and taper were from HF; I used a file to determine that

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

I have the cheap er32 chuck and collet set. The few sizes I have used

it's my talents.

Re: Just Ordered a Homier - back in stock but "Supplies Limited"

Aaron Pasteris
 

Don't sell your self short on grinding a tool - it's actually pretty easy to get a decent tool. The angles don't need to be exact. The most important part is to get a nice clean edge on the tool - that's what the sandpaper and flat are for. For production work, yes you want a macgine ground tool for repeatability, but if your turning the handles you can feel how the tool cuts and when it needs sharpening.

Once you grind a few tools, you'll see what works and what doesn't. You don't loose anything because you can just grind the tool down to reconfigure it - I have a few that are only 1-1/2" long.

Re: Basic problem?

 

Interesting, a 2002 msg has resurfaced!

For something that small, the most reliable way to get the broken
drills out is chemically. Aluminum is pretty much non-reactive to
acids, steel is reactive. Thus, the classic approach of dissolving
the broken tool out with a strong, hot alum solution. Swimming
pool/Spa & garden supply places sell alum for lowering pH.

Re: LMS Wood Turning Tool Rest, needs mods out of the box?

 

Actually, you can also turn wood with regular metal lathe tooling,
handy for making quick fixtures.

If you've got access to a decent library, look for anything by
DeCristoforo & see if they have any of the Fine Woodworking books
about turning. Fine Woodworking (Taunton Press) has a web site, I
don't know how much (if any) of the stuff is free.
