Title: Very thin mandrel
Post by: micpru on April 28, 2013, 09:52:37 AM
Does anyone know where I can get some Mandrels slightly thinner than 1.6mm? X

My first thought is ebay - look for 316 grade stainless steel welding rod. Not sure what sizes it comes in, but there seems to be a good range of sizes on there. You may need to cut it to size and round off the ends slightly with a file or grinder.

Locally welding rods are only available in 1.6 and 2.4 and you have to buy a whole tube of them, which is expensive.  Someone in the US sells 1mm ones, can't remember who though. Janet

Just looked on ebay, they are way cheaper than I paid on there and they have 1mm.  In fact one company is selling 3 sizes for a price cheaper than my supplier.  living in the Highlands is costly. :0

Pity you need to buy 1kg at a go, but no doubt you could re-sell the rest of the pack on here through the classifieds section and make back some of your money.

Also doesn't say how long they are, but probably at least 30cm I'd imagine...

I wanted to make a few small hole beads, and tried a pack of plain 1mm silver steel rod. from ebay, I think I paid about £5 for half a dozen, about 30cm long.  They work fine. (I daresay they will rust eventually, so stainless steel would be better long-term.)

I'm afraid I can't find the company now, it was a few months ago.

Keep in mind that these will bend very easily and you with took much heat they can snap x

The 2.4mm look interesting but I'd need to compare prices.  I can mangle a 1.6mm so easily so anything thinner wouldn't last with me  ::)

www.berlinbeads.de is where I got mine. Depending on how many you want, they're willing to send it at lower shipping costs, just ask them.

I bought some 1mm stainless steel mandrels from a fishing supply company ages ago. Don't know what they are used for in fishing but have made some small beads with them. They came as 30x 200mm rods, 1mm wide and silly money too. Finally found the invoice, item no. 150773967411  called Stainless Steel Pole Float Stems, price for 50 was £3.00 plus postage and packing of £1.20 The purchase was from The Float Company on Ebay.
