Hi all

I just bought a Valkyrie and was hoping to use magnets to attach the weapons.

Has anyone got much experience with magnets. I found this site http://www.magnets.co.nz/ But I am not sure what type to get (reckon I can work out sizes later though).

Any help?

Neodymium discs are the most flexible, and being round they're easy to seat with a drill. I'd go for fairly thin ones - 2mm or 3mm - unless you're planning to use them to connect quite large components. Even the tiny neodymiums will give you good adhesion magnet-to-magnet, and even the 4mm diameter ones work well enough magnet-to-steel to be able to pick up a 1/100 tank by its turret.

If you need to connect components that shouldn't rotate, you can use a couple of bar magnets, but again two pairs of cylindrical magnets are easier and more straightforward to mount flush.

Don't go near those guys mate, their prices are criminal. Go direct to US suppliers and you'll pay a fraction of what nzmagnets try to charge. Get their price list and you'll see what I mean.

I used these guys:

Yep you're after neodymium magnets, aka 'rare earth magnets'.
The discs are the shape you'll use for 99% of applications, just pick the size thats right for you.

Edit. From memory, I paid around US$7 per 100 magnets. Equivalant price from the nz outfit was around $250 when I rang them :shock:

they appear to be very expensive in NZ. I contacted a company out of auckland that wanted $3 a magnet. You can get them from aussie for less than $1 each.

The weapons on the predator i bought from crackweasel have magnets on them.. very handy!

I got a bunch of magnetic construction-set toys from the $2 shop and cracked open the plastic struts with side-cutters to get the 4mm magnets inside. I spent about $20 I guess, and ended up with about 500 magnets.

It's more work than opening a package from the States, but on the other hand I didn't have to wait for it to arrive :)

Yeah, I just got a price list from nzmagnets myself - asked about the small ones in 100s, and they kindly reduced the price to $2 per. cf $15 per 100 from the site Jav pointed me at...
