Took me about 2 hours!! Good exercise? Removed the tang and about 5mm of main body. Paul --- In 7x12minilathe@..., "jcmackastro" <jm@...> wrote:

Re: Removing Tang From A Morse Taper
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.

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. --- In 7x12minilathe@..., "born4something" <ajs@...> wrote: Apart from obvious items I now have #2644 clamps for the faceplate,a protractor for setting the compound. --- In 7x12minilathe@..., "rancerupp" <rupps@> wrote:. . .other |

The other thing that puzzled me was that the "Forward" and "Reverse" label on the power switch is backwards. I sort of *thought* the tool cutting edge was supposed to be up where it could be seen. :-) Another thing: My tail stock chuck will not eject. It's too short. I note others are cutting them shorter. Hmmmmm? I just stick a wrench between the chuck and the tail stock frame as a wedge and eject it that way. David |

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. Paul --- In 7x12minilathe@..., "born4something" <ajs@...> wrote:

Re: Basic problem?
by the way broked centre drills can be converted into nice flat bottom drills by grinding the tip square and putting a bit of relief on the citting edges

Vicki Ford has a piece on doing this (with photo) on her website. Don't know the link straight off but it is in the links section of www.mini-lathe.com along with some other neat stuff.

Re: Basic problem?
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: Removing Tang From A Morse Taper
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.

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. Have I padded your order up yet? <G> John --- In 7x12minilathe@..., "rancerupp" <rupps@...> wrote: Prices in the mags are now $529, and in-store prices show $549. Well, Ihad made previous arrangements to use the 30% off coupon so eventhough it expired on Monday I was able to use it today. TTL out the door,it cost $380.09. I think I'm gonna be happy with it. I did NOT getthe extended warranty, but I DO have a great big grin on my face. :Dother bits. I'm currently looking at:Thanks.

Re: mini laths
Druid Noibn
Hi,
Well, the first question to ask is what do you plan on doing with it, e.g., size of stock to be turned? Max diameter? Max length? Turning gun barrels or pen casings?

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. Aaron ----- Original Message -----

I'll get an order in to Enco too, they're pretty quick - I'm sure I'll have the tools before the lathe arrives. Anyone in the Northern VA area know where I can pick up some bar and round stock? I'd like to avoid shipping on raw metal. |
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. Roy --- In 7x12minilathe@..., "wrlabs" <wrlabs@...> wrote: lathe awaychisels. Then again, for turning on a small lathe, you can get handleswith using almost anything that's a usable shape.I wondered about that.
