Feather weight chassis

[Mongo]

Decisions, decisions, decisions !!!

Time to get some advice, I can't decide on what is best to use for my chassis; I was thinking 4mm aluminium but will this be strong enough or do I just go for hdpe ???

I have been looking through other build diaries but it does vary.

If anyone has any advice on what is a good bet.
Thanks

I would pick 10mm HDPE over 4mm aluminium

4mm of what kind of ali?

[Mongo]

Metals 4 you, think it's 1050 grade

[maddox10]

ali 1050? That's low strenght heatsink "pure" ali.
Better to use 10mm Ikea cutting board.

IIRC 1050 alu is too weak and will deform easily.

7075 and 2024 is a alot better for structure compontents but is costly.

6082 is a mid ground.

Hdpe is probably the best way to go for now then

I would agree that 10mm HDPE is a good starting point - my FW uses 10mm HDPE as part of the armour and has stood up to quite a lot thrown at it.
