Eliza, works great he.
Your own thoughts to make it that way?

The "handle" of the spinning wheel was going to be at the other end - but it broke. So I turned it around, turned the bottom, then had nothing to hold it while I turned the top.

So I took Ken's advice and made a jam chuck. I had to make the spinning wheel a little smaller because I don't have that much "junk" timber!

Spins good now, and I'll keep that jam chuck in case I need it for boxes, I might even make boxes that size on purpoes.

Hughie, junior has a handle, but no one is ever going to see it. It's Qld Blackwood, and I'm glad I used it on the handle because it's a bugger to turn (for me, I'm not saying that more experienced turners wouldn't love it).

But it's usable - so tomorrow I'll be able to use it! :)

Thanks!

Skew ChiDAMN!!

Blackwood is one of those woods that often scrapes better than it cuts.

A little bit of sandpaper certainly helps, too! :)

Doh! Here I have been practicing all week with the scraper, and I didn't think to use it!

by the way, Cindy, the box lady, said in her video that the scrapers seemed to catch less if they had a slight bevel on the top as well. I sharpened both of mine that way, and now I'm not getting catches.

maybe a stupid question, but what is a jam chuck exactly? And how does it works?

:p AFAIK, Tas, Vic & Qld Blackwood are all acacia melanoxylon. Although the Qld stuff tends to be lighter than it's southern counterparts, so not as popular.

I could be wrong though. Yet again. :shrug:

The jam chuck is made from some awful dusty spalted stuff and I have no idea what the wood originally was.

A jam chuck is a chuck that you make that fits the piece so tightly that you can jam it in and it won't move while you turn the other side.

- - - NOTE : might be best to drill a hole in it at the other end so you can stick your finger in and poke the piece out. Otherwise it might become jammed.

:)

The blackwood was for the tool handle. I would HATE to have tried to turn a jam chuck out of it. Hard stuff.

Seems pretty dark though skew - I've used Tassie blackwood and it wasn't as hard and it was browner as well.

Eliza, very well done. We will make a woodturner out of you yet.
Cindy Drozda uses a square ended skew as a scraper, the same as me. Only she calls it a negative raked scraper.
Make your jam chucks out of solid wood, not rotten. Chuck will hold better.

Where do you get "junk" wood from so that you have a supply to make them? Every piece of wood I have is a treasure with hidden beauty inside put aside until I make something from it.

Construction sites, especially where decks are being built. 6 X 6 inch / 150 X 150 mm and 4 X 4 / 100 X 100 mm post offcuts. Chunks of firewood. Pieces of dead tree that are taken down.

Used furniture stores that may have broken head and foot boards with big posts.

If you are concerned about your jam chuck splitting, put 5 to 7 wraps of the tape of your choice around the outside. Masking will do, filament packing tape is the strongest.

Eliza,
I agree about each piece of wood being a treasure:D
Just got to find the right use for the piece of wood.:2tsup:

Good for you Eliza! Haven't tried a jammy of my own yet but have used others.

They are bloody handy!

Veranda post with rotted bottom. Find a woody that does repairs.

"Just as an addendum", don't use new-growth oregan on softwoods either. The harder winter growth rings will mark the inside of your boxes. :(
