Thread: Stumped! Goblet turning problem

ptc: that bit of musk just has me gobsmacked. Seems to me it could be put in a gallery as it is, and so whatever I do has to match/enhance what it is.

I'll be sitting with it for a while as I figure out what that will be.

Skew: yes, I know that temptation. Actually gave into it a while ago by buying a third chuck so I could have multiple jobs on the go but have realised it also encourages procrastination.

tashammer: effectively what I'm doing is using metal turning technique as best as I can understand it. That said, the outside shaped readily enough with a gouge with a fresh edge.

It's a lovely timber with some irregular grain; as posted elsewhere, my best guess is that speeding her up reduced the harmonics as Hughie described it so well, and using a scraper with more heft reduced tool flex. That said, I think the wood is 'whippy'. Can't get more technical than that!

But thanks all for taking the time to share your advice.

I think i might treat myself to a lump of that Musk for the fog locker.

Time to get a slow combustion stove in there my friend.

Plus carpet tiles on the floor.

Plus foil-backed fibreglass blanket on the walls and ceiling.

Missed anything?

Oh yep, ugg boots ;-}

Bit late for it now (spring is here ! ) Brrrrr!
Have a black bird nesting in the Flu.

So do the pets eat roast bird?

Gee, now I'm hijacking my own thread.

Got some good progress on the hollowing hassle last night, just taking it slowly and doing what I've mentioned. [Edit: with a good edge just getting very fine narrow ribbons out; kinda mesmerising].

Cleaned up the top inside with a toothpick.

Still got a peculiar dimple left in the bottom. Initially figured it was the point mark left by depth drilling but I can't seem to get rid of it with the 3/8" Oland style tool (aka round nose scraper). Wonder whether I'm recreating it somehow. Tried coming at it from outside in but the tool starts to catch.

Anycase, to revert to other irrelevancies, turns out that my 30kph slide on the Trumpy means she's a write-off ($11k damage would you believe) so it's time to choose another bike. Just like a lathe, if you can only have one it's hard to figure out the balance of trade-offs that you can live with esp when dealers won't give you one for a weekend to try out :mad:

No they only like canned stuff !!! (the cats )
Sorry to hear about the Write Off
You will have to put some wheels on the Beast.
I have cut the Horizontal.
Will try to get it away next week.

Many thanks Peter.

No rush.

Let me know the postage.

Yeah, what would the bike equiv be of a Stubby ... lol.

Sorry to hear about the Trumpy, Ern.

I dunno about you, but my ol' girl was the worlds' best stress reliever, not just transport. Wish I could take her for a spin...

Ern.
A Vincent Twin "black Shadow."

Thanks Skew. Yep, half a day of fanging sorts out most of the world's problems!

Any case, think I've got the replacement lined up, and p.t.c. it won't be a Vincent. Once came close to buying a Velocette Thruxton new ... wish I had and had kept it but as they say, 'if wishes were horses ...'. Nope, back to a rice burner for me. Gasket Goo and broken bolts no longer hold any appeal.

So, any news on the goblet front?

And any preference on the rice-burner? My ol' man has stored his '81 Suzuki GS650G & '96 Yamaha Diversion XJ900S (not even a 1000km on the clock... bought just before his stroke. ) in my shed and they're both in excellent condition. For purposes of maintenance, they're taken for the occasional spin, of course... even though we've let the rego's lapse.

I prefer hard iron, but both these bikes have tempted me to the aluminium side.

Skew, the goblet continues to throw up challenges. The latest is some deep scratches on the underside of the bowl left by the old 80 grit. Can't get below them with paper so it's back to steel.

As for the bike, yep, deposit down on a Honda Fireblade. Borrowed one for a day yesterday, did Black and Reefton spurs and had a hoot: fast, light, nimble and not as hard on the bones as expected.

Ah, an old Divvy in the shed. Seem to recall it has a steel frame at least ;-} Now there's a comfy tourer for you. And with springtime upon us ....

Is it a Red one ?

Tashammer, I use metal lathe HSS cutters... 1/4 x 1/4 x 2.5"... should be able to get them at any metal supplier in Oz. I use them in my Oland tools.
For Goblet stems, high rpm and light cuts = easy-does-it, in my books.
Somewhere I heard of someone using a "string steady"... don't know what that is, though.

How the heck did this post get here? I was replying to Tashammer, now his post ain't here.... hmmmm. Still just a dumb yank, I guess.
