Bespoke Drinks Coasters

Hi Rob - is that the HI-MACS stuff? Heard that it's pretty much the same stuff, but like you say - much cheaper.

I was using 12mm thick sheet.

Honestly can't remember what it was without going through some invoices from 5-6 years ago, it wasn't HI-MACS, I am sure, but I think it was cast, machined and polished by a firm in Sheffield.

They look reallly nice. Will be there at the end of the month, so will try them out.
And before you ask, i don't normally stay at the Savoy.

Excellent. You'll need to order a cocktail from the new Songbook menu at the American Bar in order for your drink to be served on one of 'em - shouldn't break the bank - unless you mistakenly order the one using Napoleonic era cognac, which is around £5k..!

Ok, will definitely have a drink and make an effort not to spend that much on a cocktail.

Great work! What speeds and feeds did you use for the tiny bits in the corian?

[Wal]

You'll laugh, Boyan.

I know how you like to see the workpiece bending and you're never really happy until you've sheared at least one fixture bolt in a day.!

Corian's very forgiving so you'll probably want to start at 20m/min, 1k on the spindle (chips not dust) and full flute length on the DOC. ;)

Off the top of my head I believe I was spinning at 15-16k and feed was around 5mm/sec.

These took a long time - to engrave the circular grooves took in the region of half an hour per coaster. I made a jig to hold four at a time and left the machine to it.

Thanks for the info!

I like to push the machine, but not when material is expensive and the bit is expensive. Though when doing 200 pieces any minute could mean a day or 2 more on the job...

Corian was always on my to do list, and the mineral one also, even have a couple of new diamond engravers for such materials.

I could only imagine the polishing... last time i took a job like this , honestly i did want to give back the money i took upfront. It took some will power to finish it
