I was able to do some axe testing last night and this morning before I packed. Here is a small teaser:

Hey. The NERC Franklin registration is open on builders database. The sportsmans class still has some open spots left.

Hey guys,

Wow, it's been a while since I've been on here.

Well, Sentinel is almost finished. here's a pic.



The disks are AR400 cut on a water jet by a friend.

I may have told you previously, but I would suggest changing the name.

Yes, I do remember, still trying to come up with a new name. Maybe Sentry, yeah I think I'll do Sentry.

Those discs look nice! The wedgelets you have look prone to bending though, i assume you'd remove them if you face a horizontal spinner.

Any updates on "Bread"?

Thanks, I designed them myself. I originally had a full wedge to combat horz. spinners, but weight became an issue. I also have extras.

Bread is coming along fine and pics will along shortly.

Hey guys,

I just got in from doing some weapons tests for Sentry and ran into a problem. The weapon will spin if I give it a boost, but without it, it starts then stops. My mind is drawing a blank but I think it has to do with the brushless.

Any thoughts?

If this problem is intermittent it could be a loose wire or bad solder joint between the motor and controller. I know you said you got it fixed but if it comes back that's what I would check.

Hey guys,

I'm starting to build a Beetleweight horizontal spinner. The weapon will be pulley driven on a dead shaft. And I'm wondering how to mount the shaft to the chassis, and the weapon to the shaft without it sliding all over the place. How do you guys do it? I'm going to be milling the chassis out of (I think) UHMW.

Thanks,
Adam

When I was trying to figure out how to set up the dead axle for my current antweight horizontal spinner I wound up looking at the pictures in Jamison Go's build log of DDT for inspiration. Since I was trying to accomplish this with all off-the-shelf parts, here's a rundown of what I've wound up using:
  • Flanged sleeve bushings pressed into the top and bottom of the frame to provide a larger contact area with the plastic of the chassis as well as some compressive force
  • Shoulder screw through the bushings to act as the dead axle
  • Blade screwed to a 3D printed pulley (I used a Fingertech blade and a ServoCity screw plate since they went together easily)
  • Bearings in the center of both the pulley and the blade
  • Shim washers between the bushing/screw head and the bearings so that tightening down the screw only prevents the inner section of the bearing from moving
Granted this was all completed just a few weeks ago and has yet to be tested in a competition, so your mileage may vary.

What you describe is very close to what I was going to recommend if using off the shelf parts. Hope to see it in action in person.
