Cutting handheld mirrors

Busy making prototypes for a customer on a tight deadline who's normal supplier of this item has dropped them. Not the most technically challenging job but interesting none the less - apparently these are destined for Cape Town newest swishest Hotel in the Waterfront (refer to recent star studded opening of another hotel from the same group in Dubai)

Alan,

Very nice. Is that Oak 3/4 or larger?

Simple is nice. A nice relief on the other side would make them over the top.

Nils,

Thanks, I think that is what you refer to as 4/4, in our terms 25mm rough thickness. After thicknesing and sanding I arrived at 23mm finished thickness. The production models will probably und up at 20mm which is a shade over 3/4. The client wants simple and for the price they need it at, any further decoration is out of the question however I may well look at that if I want to add this product to my range.

Very nice. It would also look good in a lighter finish.

Alan,
I noticed you have a small thickness left after cutting pass. Are you releasing the part with a planer/sander or by bandsaw, etc.
Or, did you just take the photo before you were done cutting?

Nils, I agree but the customer gets what the customer wants...

Ros, that would be nice, but the order is only for 30 :(

Sean, the material left is only about 0.5mm (0.02") so I just cut through it with an NT cutter (Stanley Knife) to release it. I dont want to have any parts moving around as the edge finish is critical. Not all the boards are as wide as my sample one so I will probably end up using the full width of the boards to cut the shapes out, If I cut all the way through the whole thing will start falling apart :eek:

Alan,
Very nicely done! Just think of all the possibilities for designs on the other side. 3D, relief, vcarve, this could be a really neat product. Great job. :)
