New Turning Material Ideas

I've got some ideas. Does anyone know how resin impregnation is done?

Saw a vase in a store the other day. Looked like it had been turned, but when I picked it up to check the bottom I discovered it was glass tarted up to look a bit like wood. Made in China.

Been drinking the friction polish again Charlie?

Several years ago our President's Challenge was: most unusual material. So I turned a dish out of a bar of soap (called it a soap dish,) a bowl out of a hard French roll (called it a bread bowl,} a bowl in the pages of a book (titled it "turning pages,") turned a candle to look like a candlestick.

I have watched a demonstration by an ice sculptor, who worked with a chainsaw, so I assume it would not be too difficult to turn ice in a lathe. Be prepared to deal with the rusting problem.

Hey... I really like that. I will bring that up at the next meeting I go to. I think it would be a hoot to turn the candlestick out of a candle.

Way to think out of the box!

Ah - another who thinks in strange ways - and clever too!

Now where's my sketch book?

Pick up a copy of The Dictionary of Cliches - yes there really is such a book.

First, buy the resin a nice bottle of wine. Turn down the lights, pop in a Barry White CD......

First you need a male resin and a female resin...

One method (there are no doubt others).

A vacuum vessel and a vacuum pump. Some low-viscosity slow-curing resin. a few means of manipulating things in the vacuum vessel. If the vacuum vessel is also a qualified pressure vessel (as in properly engineered - do the math, you don't want a 12 inch diameter lid blowing off) so much the better.

Crude method (and far less than perfect) for no manipulation possible: mix up some resin, drop in thing to get full of resin, pull a vacuum on it until the bubbles stop.

Better method - pull a vacuum on the chamber, with thing to get full of resin sitting in an empty container. Resin is either mixed up in a container in the chamber set to pour, or outside set to run in though a tube. Once the vacuum is well-established, then pour the resin in. Release vacuum (which applies some pressure). If a pressure vessel is available, move the container to it if it is not the same as the vacuum chamber and apply pressure.

Plastic lasts longer. Limestone requires carbide skews. Massive amounts of bulk plastic out there now.

I don't think the deck plastic plank is worth anything. It is like fiberboard and must be supported.

I can get a pressure/vacuum chamber. I know nothing about the resins though other than the stuff used with fiberglass. Any pointers on what type of resin and where to get it?

What level of vacuum/pressure are we talking?

Felt is also pretty easy to make. Take a discarded wool sweater or one purchased from Goodwill and wash in boiling water - top load washer works. Dry in dryer on high with a couple of those bumpy dryer balls and Hey Presto! - Felt.

Talking radio & TV heads make great empty wood bowls. They are all wet. Their grain is weak and isn't straight. Their bark is rough, but even turned on their bias it's superficial and easily turned off. They are unbalanced and wobble, but we can straighten them out. They take all finishes poorly. They do present a few other problems, but these are removed by applying a little abrasive pressure.

They sprout and grow wild in every area, but weed killers keep them under control. They will never be a proper substitute for a sensible straight grained, native timber with deep roots, trunks that stand tall and gentle, yet distinctly firm crowns so different from talking heads.

"And now for the news, but first a word from our sponsors". Nuts! :)

Turning fine grain green wood is fun and a wet one. Rough out the bowl to double or more in the lip.. Then dry it in a microwave. Bowl will warp so go slow and when you get it out - re-shape round.

If you finish one - and want to 'play' - get it plastic in the microwave and shape it triangular or just wild.

Have to hand sand but they are unique.

: A vacuum vessel and a vacuum pump.

I've always been curious about this. What prevents the resin from being sucked into the vacuum pump?

^^^^^^^^^^^^^^^^^^^ There has to be some space above the resin, where the [ump connection comes in. As long as you keep the liquid below the hole, it will stay below the hole.
