Belting came. Fixed the sabertooth and got it driving. Found one of my motor's brushes had imploded. Such sadness. Need to get another one but they are the type with the plastic endcaps.

For the robot with the worst weight distribution ever it handles okay.

Remember chop suey?

Looking Slick harry. How did you get the bearing holes done accurately enough in your bulkheads? despite having my own mill and having been on the Axminster course I still feel like I can mess up any parts I want to make.

[RogueTwoRobots]

Because he has.....the shinning!

[harry hills]

^ this. Oh and a boring head.

It's not great great because I'm using Chinese tooling on a toy milling machine. Everthing is pretty loose. I stripped the mill down a few times and tightened up what I could. I do kind of abuse it a little bit, working heavy cuts in 2" stock with a 3" facemill. Nobody told him he couldn't be a real mill But the boring head gets me close. Goes to .02 increments lol. But I've found being gentle I can take it to roughly halfway between the increments okay enough. I normally have the bearing on hand and will get it closeish and then keep trying it till it fits okay. I don't have any telescoping gauges or a micrometer so I have to rough it a bit.

Where did you get your boring head from? Our mill is nice and accurate (besides the slop in the handle on the X axis, that is annoying!)

[harry hills]

I got mine from RDG tools on ebay. Cheapest one and it came with some brazed carbide boring bars. eBay, RDG tools, ammadeal should do them along with most places that sell tooling.

What taper is your spindle? MT3?

[Eventorizon]

Yeah, MT3. We have a chuck and collet system for it.

Stuff happened.



Stupid stepped shaft was booped out. Made a silversteel replacement.



Quickly made up a motor mount plate. Excuse the screws. I didn't have any hex countersunk M3 the right length





Assembly with the neat little standoffs from Elvis.





Carbon fiber base, HDPE rear armour.

That's so awesome! I do wonder if the connectors on the battery packs will take the current draw of the spinner and drive. Might be worth changing.

[harry hills]

If it looks like it will be a problem I'll change them out.

First up

Span the thing. Good points and bad points.

Bad points:

-belts got warm (unsurprisingly) so stretched. This is why its flapping around in the video
-I'm loosing a several thousand RPM somewhere, probably because of belt tension but very annoying all the same. Hope I can fix that.
-One belt snapped on spin down of the first time. But as the second one was fine throughout all the testing can put it down to dodgy joints.
-30a ESC hella hot so switched to the HK own brand £7 lumptroller. Heavier but it didn't miss a beat.

Good points:

-Nothing exploded
-It span with no tension and one belt
-Motor makes noise to scare opponents
-£7 ESC actually worked.
-Batteries were not hot to the touch


Also bearings came for disc. Ended up having to bore out the bore of the hardox disc a little so that the shaft sat nicely through it and didn't add any friction to the setup. TIL rubbish brazed carbide boring bars can touch hardox.



heers.

Spinning nicer I think. Can't feel or hear the motor over revving so much.

Holy balls

You should test it out on that gardengnome thingie in the back
