Boring Brick

[mrsam]

Done a bit more today, started on the wheel guards, heres a couple of pics of them just placed

Looks great!

Nice
Looks a bit like a truncated T2 from RW Series 3, cool shape to it.

Looks good! Why boring brick though? It's anything but at this point! Liking those wheels and arches particularly!
Are you still having the axe on it too?

[mrsam]

Thanks guys, yes axe is still going on when I get round to it and at the start it was supposed to be just a brick but it evolved a lot

[mrsam]

Made a start on the axe supports today and im not sure whether to have bearings pressed in or to just have the shaft run straight into the hdpe bulkheads, what would people recommend?

[Mega Masher]

Press in the bearings

I'm led to believe that Inertia XL just had the shaft run straight into the HDPE bulkheads for its spinning disc, and if that's true I'd guess that you wouldn't need bearings for an axe but don't quote me on that!

Edit: Of course, you need to make sure that your bulkheads are thick enough, I think they're usually about 20mm thick for spinners but again, don't quote me on that

Inertia XL ran into Nylon bulkheads with a 20mm bolt. With HDPE you really aught to use bearings or bushes as the HDPE will wear away quickly if you don't where as nylon is harder and designed to have things slide against it.

The orginal Inertia XL used a 20mm bolt as the shaft running directly on the 20mm HDPE Bulkheads and lasted 2 years in this configuration, the second one had bearings press fitted into the bulkheads but these needed retainers as they had a habit of falling out.

The newest one is all Aluminium so a different structure entirely.

HDPE isn't a bad bearing material in itself, and with 20mm thickness, just drill a 20mm hole and put the shaft directly in that. If it wears out, you can put in bushings or bearings. Just make sure there is enough material all alround, otherwise it will rip trough.

[mrsam]

I've got 15mm of hdpe, hopefully that would be enough? I might just run the shaft straight into the bulkheads and if im not happy ill press some bearings in

[RogueTwoRobots]

15mm HDPE should be fine, as should running it without bearings. Obviously since it's an axe, the shaft won't be rotating as much as it would if it was a spinner so it shouldn't trouble you really, but it will wear down over time. As Mario said, when that happens, you can then look at bushings/bearings but, to be honest, you'll probably end up moving onto a new chassis long before that happens.

Awesome thanks for all the advice

Finished bolting the wheel guards together, i had intended to finish the axe mounts but i've been called into work early. I just couldn't resist taking a picture with the axe on it though,
