1. safety....

WOW!!!!!!
That one just slipped past us all.
Great idea!!

PEACE

2. Wow,
This is cool, a group of people who think like I do, safe is better, thinking ahead is good. Glad I could ask a question that inspired a new forum that was needed. Ron

3. Thats why...

Were all here. To help and be helped.

PEACE

Hi Matt,

Maybe this would be a good time to suggest a Safety Forum...
Done!

• Don't ignit magnesium! If you haven't already anyway. It will not be put out by any means other than the exhaustion of fuel. Sand only makes it a little less dangerous. There is a chemical that you can buy from the pharmacy, you put a couple of drops on the material and if it turns grey it is mag. I'll try to find the info on it if anyone is still interest...still has any skin.

• Hobbiest,
That would be good information to know. If you remember what chemical it is please post it. Thanks Ron

• found info!

Here is the info for telling whether aly or mag. Magnesium is distinguished from aluminum by the use of a silver nitrate solution. The solution does not react with aluminum, but leaves a black deposit of silver on magnesium. Magnesium is produced in large quantities from sea water. It has excellent machinability, but special care must be used when machining because of its low kindling point. Knew I'd find it sooner or later!

• Hobbiest,
Thanks for the info.

• Archimedes law

Find the volume of the part by putting it in a cylindrical waterbucket. Measure waterlevel before and after the part is in. The difference is the volume. Then weigh the part. You can now find the density. Al is 2.7kg/liter and Mg is 1.6kg/liter. Safe and simple.

Best regards

• Too many pieces to that puzzle though. Silver nitrate is easier, and just as safe.
