Looks alright over all, you need to radius or chamfer those back corners though.

Which corners do you mean? You mean the 90 degree foods in the armour at the back?

Don't use HDPE for the drum whatever you do, it will turn to a black twisted mess the moment it hits anything. Any of the good Alu grades will to: 7075, 6082, 6061, 2014. Check out 720's battle against NST and look at the hole HST made in its 7075 Alu drum! Now imagine if that was HDPE; it would probably destroy your weapon.

Hmm, I thought the HDPE drum would attract criticism, in some ways you think if an aluminium drum is going to get destroyed you may as well make it out of something easy/ cheap to replace! But obviously if it falls apart during the actual fight its a probes as then odds are you are not going to win the fight, just needs to be strong enough to survive so maybe aluminium would be the way to go, another option I guess would be nylon for increased rigidity but that may be too brittle and still has a lot of the issues.

At the moment the drum is solid material, there is no shaft going all the way through but a separate, 40mm shaft at each end so the plastic ought to be fairly rigid. This does mean I could use the aluminium and just bore a hole through the centre to save weight but ideally I want the walls to be left as thick as possible to avoid the drum getting crushed/punched through.

Perhaps a composite drum could work, metal centre to give rigidity and plastic outside or visa versa.

GR02's are no longer in production so you would either need to go Ranglebox or Banebots, either of them will do fine though the Banebots are much lighter but more costly.

Yeah I realize the GR02s are out of production so would be a matter of trying to get some second hand ones, depends really on the cost of the RangleBox units which hopefully we will find out soon.

@Jamie: yeah the belt isn't shown but will run directly onto the drum, hadn't thought about the heating issue, didn't realize it would get that hot! And if I were to go HDPE I would have to give some thought to how the teeth where mounted, I was thinking of counterbored bolts in the teeth going all the way through to the other side then into a threaded hole in the tooth on the other side. Alternate bolt direction to keep drum balanced.
