Team Eventorizon: Build Diary

Plastics can always retain water, try drying it out, might help a bit.

Its lived in our back room next to the radiator for the past 6 months so I doubt it.

[harry hills]

Don't do that.

I looked up HDPE and it is said to not adsorb water at all, one of the reasons it is used for chopping blocks and food containers.

[Eventorizon]

Its Nylon 66, not HDPE. That was one of my annoyance earlier, and no I won't actually put it on the boiler, even thought I doubt it would do anything to it since it only gets luke warm.

[RogueTwoRobots]

If you want a boiler to dry it out on, you're going to have to find a 20+ year old open-flued, old-school one. Modern ones are too efficient these days

You want to keep Nylon with the water in. It gets pretty brittle without! We leave nylon wheels in storage in a sealed bag with a small amount of water in the bottom.

Need some help with the Banebots P60 gearboxes.

I am trying to remove the main shaft from the front of the gearbox. I assumed it was a simple matter of removing the Circlip from the back and sliding it out but neither of them are budging, the move a few more mm and then stop.

Am I missing something or do I need to give them a tap with a hammer? I don't want to do that until I know that's what the need.

[Mouldy]

they should press/tap out... sounds like the circlip groove as burred over... tap it back into place, clean the shaft up with emery cloth then it should push out fine.

[Eventorizon]

Thanks Dave. When you retapped the threads did you just go over the original 10-32 with an M5 Tap or did you need to pilot it out with a 4.5mm bit first?

[calumco]

the drill for an m5 tap is 4.2mm
or 4.65 i think it is for a roll tap

[geeza]

I just ran the M5 cut tap down, no need to drill it out.

Calum you are right it is 4.65 for a roll tap

[Mouldy]

I just ran the tap down... its not far of the original size and its a pretty low grade ali, so cut taps easy.

[Mouldy]

Lol ed beat me to it, nearly word for word.

Well in 20 minutes we will be starting the drive up from Banbury for the Wednesday to get some much needed driving practice in. Binky's new weapon makes it a rather different beast to drive and our small 2m arena isn't big enough to really let it flex is motors.

Conker is ready to rock, though a bit cramped inside and both machines are actually near the weight limit this time, not 800g off which is nice.

On a different note, one of our transformers for the Turnigy Accucel 6's packed in so we only have 1 charger for 6 lipo's so if anyone has a spare or even a spare charger they could lend up, that would be amazing!

See you all at GSL and good luck everyone!!!

[Eventorizon]

Seems I haven't posted in this thread for a whole year!

Not much has changed in either robot. Biggest different is Binky now has a HDPE bulkhead after Decimator destroyed the Aluminium one, aside from that it will actually get to use its new disc for the first time at GSL. We got to try it out at MMM last September and the bite it was getting was ridiculous! We are also able no to run a large 6S lipo rather than the 2 small 5S packs giving us extra run time if we think the fight will last the full 3 minutes.

Conker 3 has a 450Kv motor rather than the original 520Kv meaning while it looses top speed, now a mere 10'000rpm down from 11'500rpm, its spin up time is even faster and it draws less current meaning I can actually go a full 3 minutes before I run out! I am still surprised that she only weighs 13.25kg, but it does mean I have weight for extra's if I need them in certain fights.

With no knowledge of who we are fighting... looks like we will have to just roll with it this year. Good luck and see you all in the arena!
