Does anybody have source for 2.5 or 3mm Brass sheet suitable for engraving.? Need piece 19" x 14".? ( Yes I know it's bloody fortune.!!)

If you can do with a bit less than 2.5mm then nick some of those brass door push plate things :nonchalance:

Aluminium Warehouse used to sell brass, but I can't find it on the site now. Might be worth asking them anyway?

It's ages since I've used them but Metal Supermarket at Coventry may be worth a try.

Nope 2.5mm is the lowest can go. Think I bought some the last brass AW had.?

Tried them far too expensive 45 more than been quoted.!! Can't believe the differences in prices I've had, up-to 60 difference for same grade. .:pirate:

Tried ASC metals ?
Mind you wherever you go it will be expensive. Last 1/2 sheet I bought, 4' x 4' cost 120 in 1/8" thick, hate to guess what it is now.

Forgot to mention you could ask Metal Stockists: ASC Metals Lincoln Ltd. - Metal stockholders for East Midlands/North of England (http://www.ascmetals.com/)
I ordered lots of aluminium from them recently, don't know what they're like with small orders?

Edit: Oh John S beat me to it there..

If you want nice engraving use compo brass, that's the stuff the clockmakers use to cut their tiny cogs and stuff out of, cuts like a dream compared to the usual.

Cheers Robin did know that and actually the cheapest price I've had so far is from a clock supplier.! 85 inc vat

Apologies for teaching Granny how to suck eggs. I'd be afraid to cut an 85 hunk of metal, you are very brave.

I keep a handy piece of compo with a thick layer of shellac on one side.

No apologies needed only a few days ago I didn't know it was called Compo untill asking clock makers what they used.!! Compo thou is just CZ120 brass which is engraving brass and what I was looking to buy anyway.!

Not unusual for me to cut expensive pieces of metal thou must admit I'll not be walking away from this one.!!

Edit: Recently I've had a death in the family and can you believe this job is to repair a Grave stone that got vandalised weeks after funeral.!!. . . Some Evil Bastards and If I catch them they'll be in a shallow unmarked piss hole.!! (After I've strapped them to machine and fly cut there faces and distinguishing marks off before they take there last breaths. .:mad:)

Better Metal Stores in Alfreton are a good source for small amounts of sheet, bar and profiles in most materials (metals and plastics) but they are probably pricey, but a useful supplier nonetheless.
Proops Brothers in Fleckney have 3mm sheet 250x500 (mm) for 35, but I don't know the grade. They also have a lot of cheap (and cheerful ?) bits for small engineering.

Hah, my current record for a single part is about 320. It was 1" aluminium plate.

I went there once and got quite a few bits.. can't remember what but I'm sure it was useful!

I have a 2'x4' sheet of 1/8" thick CZ120. I could sell you a piece from that if you still need it

John S - the days of getting a 4'x4'x1/8" for 120 are long gone ( especially in CZ120) I just got a sheet 4'x2'x1/16" and the best deal i could get in CZ120 was 85 + vat - after a HUGE amount of shopping around.

Best Regards,
David

Made two of these a while ago.

16" diameter, 6" deep and two sit back to back and offset, that's what the small cut away's are for. The slots hold carbide inserted blades and overlap very slightly so the whole 12" is covered by blades.
This assembly then runs at 7,000 rpm in an industrial pencil sharpener.

To be honest can't remember what the alloy cost but I know it was pucker time when machining.

Damn John that's neat work. We are making rollers from 17-4 PH stainless for a local maltings - 380 dia x 180mm wide. You always have that moment where you wonder if it could all go seriously wrong and mess up 600 of material. Do you ever work with any exotic materials like monel or inconel?

Nothing exotic, too frightening but it aways pays to have one lathe and 5 welders :barbershop_quartet_

Thought about a casting but this puppy at 7,000 revs is a bit scary.
