Bar Spinner structural advice?

can someone explain why I got a warning for bad language on the above post??!!

Irony.... After that conversation the bush has worn out in the turbo in my car

I'm sorry about that....maybe it's now the time for an upgrade!

do 5 series bmw's have ballbearing turbos? lol

Fantastic, thanks so much for the help everyone! I've redesigned around it, I've got a 20mm rod for the shaft on the way, and I'm looking into some much thicker bulkheads now, going to see if I can get something working with a bit of steel (a bit like how Last Rites' looks, with the frame) but again, it's just seeing if I can get the parts that'd work with that!

Just a matter of engineering this bar a bit better now, It's still mild steel for now (I've got plenty of it to hand for ridiculously cheap prices, somehow...) but I'm definitely going to upgrade it to something better when I get the chance! Been having a look at a few bearings, and I should be able to get things all done under budget (going for less than £200 overall, currently on track to spent about £180) if everything goes to plan, so that's all a good sign!

Also, those bevel gears from the picture of Buzzbar's spinner - are there any like that available to buy anywhere, or have they been machined specifically? I was having a look at a few bevel gears for the system, instead of a chain drive (more reliability than a bike chain!) but they're all either really small or not quite suitable for the application...

Thanks again, it's a huge help!

Angle grinder gears have been used by some spinners, if that's any use.

[typhoon_driver]

mild steel is cheap anyway so I'm not surprised if you are getting it at a low price.

Thanks for the tip! I'll have a look, not entirely sure how angle grinder gears will hold up with the strain of the bar suddenly stopping, but I'll give it a go!


Mild steel is very cheap too, I know someone who's got loads of small offcuts, and they're practically giving it away to me (and they've offered to weld it together properly too, so that's nice of them!) so I'm going to use as much as I can for the bodywork for now, and it's at least a decent enough body for the thing! I'm going to upgrade in the future to better materials like Hardox or something if I can fit it in the weight, but for now it'll hopefully suffice! I'm not using too much either, I'm getting the machine as low down to the ground as I possibly can, and only putting thick armour on the sides (please be kind on me, axe-wielders) so it's not too heavy either... or at least, that's what I hope haha!

360 was the first big brushless spinner in England and it uses angle grinder gears... They haven't even worn down a bit yet...

I take that back then, guess I'll get some angle grinder gears for it after all! Just need to find some that fit and the job'll be a good'un - thanks!
