Very nice! Its awesome you have access to the tools to manufacture parts that complex. The new weapon looks brutal, hopefully you can get it in a fight soon
We have a spring event you are welcome to participate in on May 15th in central PA. Rage in the Cage is being held at Knoebels Amusement Park. There we can socially isolate and the event will be outside under a huge pavilion. We will be using the same octagon arena that is in the video that you shared. Great weapon video... I will be sharing it with my classes this week.
Hindsight I should have, I was just worried I was going to break a 10-32 thread mill because of how small it is. After seeing how well the hardened 4140 thread milled I think it could be done in the AR450 as well.
Pretty awesome man, its really cool to she how you have evolved over the years from when you first fought razor. Super happy for y'all. One question, u said 16000 rpm, now I get how razor could do it cause the motor is in the weapon, but for the new robot doing a belt method u would have to be a 1 to 1 or are you guys getting new motors for it?
We're planning on using the same 50mm outrunner that Razors Edge uses with a 1:1 belt, but have room to change the gearing depending on testing performance.
@@RECombatRobotics ok gotcha, I'd be careful about the 1 to 1 that is going to be hard on the motor, cause ur using a pinion and the motor takes all the force at one point on the axle unlike razor where it has the entire out side of the motor to absorb. Pretty sick though. I'll be wait for ya.. lol if they dont cancel again
@@cadenkorzan I'm planning on counterboring an additional bearing into the frame where the motor mounts to help support the shaft (8mm on the motor we use). The team is planning on attending this year's NRL national competition if it's still on.
Very nice! Do you have any resources/can you help me design a 15 lb battlebot? All tutorials on the internet are on 3lb beetleweights or whatever. Anyways, Awesome job!
Thanks! There isn't nearly as much info for building 12 and 15 pound robots as 3lb bots online, but by far the best source I've found has been the NHRL discord server. The 12 pound chat is full of 12 and 15 pound builders who post their designs, test findings, and will happily give advice to you if you post some info on there.
I’m a machinist and I physically shuddered when you said you tapped those holes. It seems like you aren’t the kind of person to do anything without a good reason, why have a custom tap made rather than thread milling those features?
I wasn't as familiar with thread mills at the time to have the confidence to do those small holes. In hindsight that was definitely the way to go though. All my new designs use through cut holes with the waterjet, then I only have to clean up the bearing bore.
Why make you weapon so complicated? Just press fit the bearing straight into to weapon use some green locktite and tape and thread into the weapon and bolt the pulley to the weapon
I needed to distribute the load of the weapon over more bearings than I could fit inside the 5/8" disk, the bearings are relatively small because I need them to be capable of about 20,000 rpm. Adding properly support bearings inside the pulley also helps with the strength of the weapon assembly against sideways hits from horizontal spinners.
Oh ok make sense. Just a tip look into needle roller bearings on McMaster. They have some for high rpm I've been using those for a long time same with other schools and i have never seen one explode. Some teams also use lubrication brass bushings as well
Very nice!

this is an awesome video, cant wait to see the rest of the robot!
Great video, really cool stuff

This is super cool... it makes me want to build a little fighting robot too
I bet if you made a hollow drum with helium inside it would spin faster for less. Pretty awesome workshop and nice video.
Great video!
Real nice video
I'm going to go out on a limb here and say I think you know what you're doing :)
Great video! Very professional!
When is your next video? Looking forward to design video in future episodes?
Thanks! As long as the NRL National Completion doesn't get canceled, I should have some videos surrounding that out next month.
Why not threadmill your threaded holes, instead of trying to tap?

Isn't the 'w' symbol for angular velocity in the equation/formula thingy a lower-case Greek 'omega'? 🤔
Yes it is. I think I just wrote w in my script and forgot to correct it.
