I've used a stainless bowl in the past, it was one I nicked from the kitchen, I used it with dilute sulphuric acid. I find it far more convenient to use a crock pot, much less fumy and less likely to...

Given the health and safety concerns of lead these days I would think it's pewter(tin). I've only ever used lead but that was years ago. It's fully recyclable, the down side is that it can muck up...

I came across this clip today which you may find interesting.

He has done a follow up video that discusses the mould failure. He allowed for the thickness of the metal but the 3d software had an adaptive mode switched on which automatically adjusted the other...

It is available to the ordinary punter. An interesting article, this is an article about the same part which comes with a video.

It can be a bit of a black art to find the sweet spot for a particular cutter and that can be different when the cutter is new and really sharp and after it has been used for a while.

I think that what is probably happening is that the tool tip is heating up and the plastic is sticking to it. This also can happen when machining aluminium, the chips that come off can become welded...

Great idea Matt which has produced a very nice spoon. I like the stone set in the handle.

The methods that require heavy duty equipment may not be available to you but there are methods to shape sheet into hollow forms that are suitable for one offs or short runs. They are based on a...

Here is a further video of a spoon being forged and stamped. He uses tin instead of lead that the old spoonies used to use. You should be able to see how this method could be used to shape a hollow...

Spinning requires some heavy duty equipment. There are some significant forces produced. The pushers are large and fit under the arm so that you can get your body weight behind the tool as the video...

Hi Karen,

Yes I am happy with the Eakins Microscope although I don't have any experience with other scopes so can't do a comparison. It enables me to do more detailed work that I would not be able...

How do you pick up the item? Do you touch it at all with your fingers and if so is it by the corners?

Just trying to rule out possible problems.

I've had some chips on the edge even when it has...

Very nice indeed Bob.

Very nice ring, I love your method of texture. I've been looking at making something similar but have not taken the plunge yet.

I agree. I've raised a number of vessels with both hammer and spinning. I've never raised one with a spherical bottom. The methods I've used for estimating blank size has been stated by James. I've...

A few images of James popped up on Instagram today from 1982
