One of my multiple parts files for €2 new price €35. The overal...

Re: AntWeight Parts Online & Offline

I am looking for a motor / servo with more than 10kg / cm torquethe more the better as speed isn't important. I have used a fingertech silver 300:1 but the gearbox failed in the middle of the chain. I am going to get a 600 : 1 motor but wanted to see if anyone knows of anything under 40g.

I have stripped a 298:1 HP motor on 2 cells. That was stalled but not for very long.

2g) Any system involving the use of pressurised gas or liqui

Parts have become light enough to in theory make a CO2 regulated antweight, All the parts that have higher pressure would have to be rated for this.

The weapon could be limited to 100psi to meet the rules or 150psi to meet the maximum rating of the valve. What are peoples thoughts on this?

What you need: Drive motors, these can be either stepper or servo. Steppers are cheaper but also not as accurate. Motor drivers for the type you buy, need to ...

Re: CNC mill build thread

I have been working on this mill until I have some new ideas for robots. It is now up and running although there is a bit to much backlash on the X and Z axis, Y currently has 0.035mm 8) It took about two weeks to make the parts to mount the ballscrews and bearing blocks (Ebay). I also had to modify...
