How I make Corian armbands.

[Sturdee]

Making wooden armbands is quite straight forward and there are many sites on the net that shows how to do it.

When I wanted to make armbands out of corian there were only a few and seldom saved the circular cutout for making a matching pendant, which I believe make a much nicer present.

So I made a reuseable face plate jig to hold the blanks.

They all involved making a jam chuck for mounting and then turning the outside. Whilst jam chucks may have their place it requires a lot of work to make either the ID of the armband the same or making a jam chuck for each pendant.

This is like driving a model T Ford instead of a modern car, so I made an adjustable jam chuck to speed up making the armbands.

Whilst my method is not the only way, it works for me and makes making armbands quite easy.

I start of with cutting the corian blank to 110*110mm square to put in the reuseable face plate jig.

This is one side of the jig.

and the other side.

On the front is rebated timber that will hold the blank and one side is detachable for inserting the blank.This rebate is sized to the corian thickness.

The blank is inserted.

Ready to start turning.

Internal ID marked out.

Pendant disk cut out. For this I use a parting tool.

Now trimmed to size on the table saw. Ready for turning the outside which will be the next post.

For turning the outside I made an adjustable jam chuck which is bolted onto a Gary Pye chuck with the wide jaws. These jaws have extra holes tapped to m6 thread which means they can be adapted easily. To make the jaws I did some split turning (1st time :2tsup:) and it's graduated for different sizes.

On lathe ready for turning with tailstock support. This makes it a simple exercise in spindle turning. For this I use a scraper.

Turned to final thickness.

And shaped to final shape.

After hand polishing using the Micromesh pads and a final polish using car polish the finished armband with the pendant disk on a background of some nice green corian.

Enjoy and all comments appreciated. If there are questions I'll try to answer them.

You put a fair bit of thought in to that process Peter, thanks for showing it in such detail, well done:2tsup::2tsup:

Peter its the first afternoon I have sat indoors for ages :~ bloody rain and old joints.

Like the WiP pics knew they'd be good ones. :2tsup:

Q1 why don't I read the notes first :doh: last lot of pics q was to be "why such a long jam chuck with different steps."

:U Answer cause if I was making different sizes I'd probably do similar.

A neat setup Peter.
Thanks

Today I bought a Sorby 1/2" beading cutter to fit their multitool and this has made the final shaping easier and more uniform.

Very nice. I hadn't thought of doing the insides first. Your process allows more variation in both inside and outside diameters.:2tsup::2tsup:

Cheers,
