and suddenly his rebuild makes more sence.....

Yeah, because it didn't make sense beforehand :P

I am sad I don't get to fight Rumdroll again : '<

Let's be honest, we've been drawn against each other for the past two years and both have been over very quickly without either of us really attacking the other :P
But if we're both still intact and running at the end of the event, let's get a fight on the go.

@ Jamie: what sort of bearings are in the drum?

These ones: http://simplybearings.co.uk/shop/Bea...duct_info.html

I didn't want to go for plain needle rollers again, despite the fact they've served me well for over six years. I was going to go for ball bearings, but for a 20mm ID the OD was going to be too large to fit in the end of the drum tube/endcap. So I went for the above option as a sort of middle ground. And yeah, there are thrust bearings either side of the drum.

Wait, what? You mean its not going to be you against Jamie in the final match?

@ Jamie: what sort of bearings are in the drum? They look like giant needle rollers in the photo.

[maddox10]

Those are huge needle roller bearings.
At a guess, 25mm axle, 25*30*20 inner race, 30*40*20 needle roller in drawn closed cup.

I guess 20 because my bearings are 20ID... you were meant to use angular thrust bearings though jamie! #cheapimitation

Tried those.. they exploded :-P I am sure Jamie doesn't want to explode as well, that's bad!

Thrust bearings either side of the drum?

[craig_colliass]

Though I have never had a drum spinner I can testify to the durability of taper roller bearings on fighting robots.
I calculate Saint has been in over 250 fights in it's life and in that time after all the flips and hits that robot has endured. The bearings on the big wheels are perfectly fine. the exact same system is now fitted to Gabriel.
But like anything they have to be fitted correctly. I'm sure Dave, myself or many others can advise.

[Mouldy]

yeah.. your ones exploded because you didn't pre-load them and had them fitted terribly... mine are fine.

[overkill]

Those bearings have excellent specs, with higher radial load capacity than a 20mm ID tapered roller bearing - you definitely exceeded Mouldy's design there . If you ever need an upgrade, look at this:



Specifications: http://medias.schaeffler.com/medias/...PP*SL045004-PP

2.7 times the dynamic load capacity and still only 42mm; I am looking at these for when I design a drum to replace the beaters in my current bots.
