I have gone off the idea of a base made from 6mm Polycarbonate, although i have a huge sheet from the tip - someone threw it away, was a shower screen! i feel like i need the strength, and should i be upside down on the receiving end of an axe, it can shatter.
So perhaps i need a trip to my local-to-work scrap yard and see if they have sheet titanium going. i have managed to get some bits from them before, so why not!
Anyway, this weekend being a snow day weekend, i thought i would get on with some robots stuff. Sadly today was a plan to grind the panels for the front out of the Hardox sheet but alas, it rained! So no outdoor stuff to be done.
i did make a start on my cabling and soldered on some motor connectors and plugged it in to my Electronise esc, although im really wanting to get the TZ85A. Sadly the stocks accross the country are none.
Luckily, i headed to my local fav auction website and randomly checked for TZ 85A esc, and wow, one appeared. So i grabbed it!
Now i have 2 TZ85A esc for my drive controllers instead of the electronize ones (i have 4 of them now)

The axe mech, im starting to think about using chain drive instead of single pulley as this is the way most rooters go. plus simply bearings, or bearing boys have an offer on.

I also wanted to print out some sample motor mounts for use on my bot - i sold 4 sets of them to someone after them for an R2D2, i wonder how he got on with them? Sadly i needed solid works to work on my laptop, but i couldn't access the activation portal so couldn't transfer my license from my work machine to my work-at-home machine. Therefore, i never did make these. Will just have to make them Monday at work on my CNC Mill.

Oh well.

So the next plan is to at work, use solidworks to correctly check what model of motor mount im using.
2. modify the motor mount to fit the new rear chasis shape and mounting options.
3. check that 18mm HDPE is good enough on the motor mounts.
4. machine up brackets to hold on the rear
5. go to scrap yard and find a suitable material for the base. Design has limited it to 6mm max.
6. grind out the front panels.
7 re-weld the other side panel that i did badly.
8. program and test the ESC tz85a
9. rewire everything including the lights.
10. oh yeah... the axe mechanism

the list can continue...
