q2 - use of ACM for tool storage

[desbromilow]

Second question mulling around the brain box....

ACM (the aluminium clad sheets of plastic used for signwriting) - I am contemplating using it for making up the storage for my ER collets. basically a sheet of ACM with a grid of holes drilled through for the collets to sit in.
It's been a while, but will I run a risk/ concern with having the tool steel of the collets in direct contact with the aluminium?
is there plastics I need to be aware of when in contact with tool steel? (I am so used to watching what woods I use to avoid tannins causing issues, but the old memory says there are certain plastics which are formed with acids in the reaction - do I face similar issues?

Thanks,
Des

Aluminum and steel shouldn't be a problem. As for plastics, I 3D printed collet holders in PLA and they are working great. You could print in PETG is you wanted more fuel resistance, but lubrication oil on the collets won't do much to PLA in my lifetime...

Thanks BuffaloJohn, that is great to know. I am just starting in 3D printing, so will use more traditional methods for a while. Once I get across the modelling and printing better, then I'll look at some PETG projects (3M backpack conversion for their half face respirator is one of the first projects I'm aiming for.)

I'll make a run with ACM first, and then worry about options later.
