There is a 4*M2 bolt pattern on the motor can so I'm using that to mount the blade.

My motor shaft is only 3mm long so even with the current 2mm disk I have 1mm ground clearance.

EDIT: ah just realized... I didn't have the weapon in the right direction, the actual bite isn't as ba ...

Update:

Claymore with experimental Ti weapon. The amount of weight I was trying to get and the low density of Ti meant I had to use more of a disk design, so here goes my bite depth.

My motor shaft is only 3mm long and I need at least 1mm of ground clearance so that's where the 2mm thickness came from.

But you are right about 304. It's soft.

I guess one option is to have a w ...

Yeah that's probably a big part of the problem.

Just now I found out that the motor mounts (basically hose clamps) might also be responsible as the motors are not exactly horizontal.

I guess you could flip the spinner blade around to get it a bit closer to the ground. (assuming your test setup is inverted compared to what would go into the final bot.)

Update:

As I wasn't able to compete at the recent FMB event, I have done a few weapon tests. And I have had some problems with the weapon system on Contraption.

So the machine shop I found on Taobao just told me that they could make my weapon bars in time... I guess I will have to get those made in Australia...
