Yeah I can get the disc closer to the ground, 5mm off the ground should be enough. A ramp at the front would not be to difficult either and I can make it removable so I have a choice over it. What disc materials do people use, that model is currently set for carbon AISI 304 Steel (Its the most dense of the preset steels in solidworks)
omen's disc is hardox, not sure what grade though (can anyone enlighten?). to expand on my previous comment i like the looks of your design i'll be interested to see how well it works.
Here it is, current weight is 12.5Kg thats with no wiring, relay for the speed 900's and the receiver, as well as all the nuts and bolts... I think this is now design 5 version 8 or something stupid...
Well its looking great,
as for disk materials people use Hardox 450, titanium and steel
Looks like a nice design modification. As Gary said, less fancy but much more robust and tried/tested. You've also negated the components, material and electronics for a srimech which is guaranteed to make your life easier as it's one less thing to go wrong.
For cost-to-strength, I think Hardox 450 is the first choice. It's hard by general standards, but as a spinning implement it's not the hardest material around. So if you put a nice sharp tooth/teeth on the disc, it'll have blunted after a few fights. But blunt teeth aren't bad. Boner's teeth have long lost any form of sharpness but can still rip things to shreds. Plus you can always reshape and resharpen your teeth before an event.
Harder materials tend to come from the realm of tool steels. P20, S7 and D2 are the few I've seen used or talked about in combat (although I have no experience of using them myself) but they also cost a lot more to buy and then have machined. If you've got the money though, may as well go for it.
Drumroll's current teeth are a material called Supralsim 690, where 690 relates to the hardness of the material. Compared to the 450 value of Hardox, it's a tougher material, but they've not yet been subjected to enough fight-time and impacts for me to tell how well they last.
P.S. If you're still struggling for weight at any point, the Nylon base is probably a little overkill. Can't remember what you said the thickness was, but I use 3mm aluminium and it seems to be more than capable.
if you can manage to get your hands on some higher grade hardox like 600 or 650 you could make a nice disk from it. a job lot of disks were made from hardox 650 a while ago, i think inertia xl runs one.
by the way, seeing as you've come up with a nice viable design:

tried to embed but the mysterious art still eludes me..
Apparently 650 grade isn't available in thin-ish form and that those discs were made as part of an experimental batch or something (or so the guy from SSAB told us a few years ago on here). So if you want a hardox 650 disc, you'll have to wait for one of the batch to come up for sale, assuming its dimensions fit your needs, or spend a tonne of money on a huge big thick bit of 650 and machine the hell out of it :PQuote:

Don't know why embedding is causing a problem for folk. Just click the 'youtube' button below the bold and italic buttons in the posting section and then paste the link between the brackets. So in text form, it should look like this:

I'll just leave this here

hmm, it appears i forgot the / in the last set of brackets. you might want to look into other types of wearplate then. i know dillidur goes up to 500.
also give these people a call first, they have loads of hardox/weldox and on site waterjet.

thanks gary, that illustrates my point rather well.
