Quite a departure from your previous featherweights will. Looks great though.
Best regards,

Just seen the photos and a nice looking chassie Will
I am a becoming a big fan of HDPE. Easy to use, cheap and strong. Planning to build the heavy out of it.

Il sign up once I check my diary. Will be a lil strapped for cash and will have to carry a tool box and a robot but hey Im a big lad.
Ooh if Kenny is going I could hitch a lift. Need to also look for someone to share a room.

Thanks for all of the nice comments.

This is the first time that I have used HDPE and I am very impressed, it was easy to cut and work with and so far seems more than strong enough for the chassis.

I will be fitting the drive and plumbing the flipper tomorrow- I will try to get some videos online when I test it

The main issue I have had with HDPE is that its very flexible. Trying to screw two parts together can be hard to get done acuretly due to its bending.
Also you cant tap it. Probably its biggest draw back.

today i got the motors for my featherweight
2x windscreen wiper motors...
now before you start yelling at your monitors"he should have used gold motors...he should have used drill motors etc..." can i just say this is going to be a very low-tech feather ( most of the ideas are taken from rex's robot challenge) for example, my pneumatics consists of a lemonaid bottle and 2 bicycle pumps, i do not want the total cost to go over ?250

Hi Marco, I don't know if UHMWPE is different from the stuff you're using but I'd say that its flexibility is a bonus, and I can tap UHMWPE no problem.

Marco- the entire chassis is tapped and bolted together with no problems so far
