CNC Clamp Screw Locking Improvement

Скраћена веза: https://pedja.supurovic.net/veza/9634

With hobby mini CNC machines you get simple and very cheap clamps that are not easy to use.

It is hard to fasten it because screw turns along with nut, and as screw head is in T-slot of bead it is not easy reachable to block turning.

This is small rectangle peace you can attach to screw head that will block it turning within T-slot.

It makes using clamps much better experience.

You may make it from mdf, wood, plastic, metal, whatever you like.

Dipole Antenna Center Insulator for SO239

Скраћена веза: https://pedja.supurovic.net/veza/9625

Building dipole antennas is always some kind of improvisation. Center insulator is quite simple and may be made in short time with jigsaw and drill.

As I jumped in CNC world I need some simple tasks to learn how to use FreeCAD and other software. So, dipole center piece is ideal just for that. I’ve finished project and learned a lot in the process.

You may use CNC mill or 3D printer to make this part. Pay attention to use material strong enough to survive possible strong forces.
