Looks good, I will have my Mark 2 robot ready early next year and hope to meet you at an event! :) My first attempt came in at 12kg and the improvements take it to the weight limit.
Will you be at the KOB event in fall next year?
So after more CAD work, I did a fancy render of the near finished CAD of CSB 2.0 with the four-bar up and down. Ever the artist I had to make a stat board for the projected stats of CSB 2.0 based on intended materials, calculated weight, speed calculations.
It's freaky to me that I first had the idea for CSB 2.0 back in mid/ late 2017 and I actually gave up on it but after a long break from it, better research, actual CAD software and

Nice robot. I am looking forward to see its first fight.
Thanks, I'm looking forward to having CSB 2.0 fighting this year, already got the drive motors and the first stage of the weapon mechanism the motor and p60 64:1 gear box. The CAD is nearly done I'm currently checking my profiles/ DXF files for the Parts that'll be water cut at some point.
This looks really impressive, lovely CAD work. This could be tough to beat!
Wish I could CAD this well XD It looks great!
The Hardox arrived from K-cut. Working on the Aluminium threaded bars, well I was till the tap broke and the drill bits went blunt. :( New Taps and drill bits ordered.

Shame to hear about the drill bits but those are some nice hardox pieces! Didn't realise the build was this far in progress, looking promising.
Looks fine congratulations, love it.
Can k-cut make angled cuts for the wedge, or do you grindig it in shape?
Kcut are a water jetting firm who also have access to a press. They would of cut out the metal as designed a d bent it if required.
Basically what they said.
After a few days work, I’ve got a pretend-O build, I’ve finally moved CSB 2.0 from the floor to its cradle. I also test fitted the motors and part of the weapon mechanism (using the locking bar as a stand in for the shaft). Some of the threaded bars are a bit off in places so might replace them otherwise I'm going to have to do a lot of hole filling and resizing. Granted I'm dreading having to countersink some of the holes. :(

Some Aluminium parts arrived from Dave Moulds and Engineering Network. The pretend-o build now includes the side panels. Sadly all of the threaded bars for bolting the frame together had issues with holes not being accurate enough for the job as in each one had at least one hole out of place, the drill wondered when drill pressed it. I’ll get more aluminum and try to drill and tap them better this time.

When you drilled the holes, did you use a centrepunch? That should make an indent to stop your drillbit walking off.
Hmm. Maybe try one of those spring-loaded punches? Not sure if they'd be good enough for hardox.
I used one of those spring-loaded punches on Voodoo's aluminium, works an absolute treat!
I assume there's some kind of magical knack to getting holes in the right place when drilling metal...
If you're making lots of piece of identical ally bar, is it worth making yourself a little jig? A scrap piece of metal (or even plastic/wood) with some 2mm through holes drilled in the exact right places. Clamp it to the piece you're working on, then use the pre-existing holes to line up a 2mm drill bit. You'd only need to go in a couple of mm on each hole with the jig in place.
Might be a bit of a faff to make but that way you only have to be accurate once.
Oh, and the robot looks awesome!
Jigs work but can be a pain the that's ass. Just measure and measure and measure again. One option if you get deep pockets and space is a 3axis sliding table and a bench drill. Or a mill.
Or you print a drawing out an glue it on the part as a mark template.
Ok got new hole punch coming along with a proper scribing tool should hopefully help a little.
Been a while. Coolspeedbot 2 is getting there wiring nearly done the bodywork nearly fully put together.
I did a weapon test which you can find here: https://youtu.be/JjuGP6iDMoc
For more detail on whats been happening check out my facebook page: teamcoolspeedbot
And here is a bench test of the drive: https://youtu.be/oQ8gEGHQQuw
Looks very powerful.
Thanks, would put out 9-10 mph currently if it had wheels on, but when it runs on the 5s lipo I'm planning to use it should put out 12-13mph.
Looking like a powerhouse! What ESCs are you using for your brushless drive setup?
They are the old BotBitz BB-85A, I was running them as brushed ESCS in CSB 1 but I converted them back to running brushless motors.
Just wondering what firmware you used to convert them back to brushless?
It was firmware that was provided for me already to flash, by another person. So I've not had a look at the firmware itself.
Preformed a new weapon test for CSB 2 it's working far better now, still need to resolve the issue with the motor mount slipping (will be fixed when I get the new base plate made) and try to work my mind out of this overcareful state, I'm still trying to be gentle with the weapon despite the fact it should handle being opened and closed at full speed.
