Updates to portable car table

I have been using a piece of ply for years as a car portable operating table in many cars and still do, described here:

After I made a post on the UK VHF Contest group on Facebook I got a reply from Dave G3WCB showing his cool car portable setup. I had already very recently thought of doing something similar but seeing his setup gave me an idea for a simple and quick update to my plank of wood.

I already locate it over the steering wheel for some security to stop it toppling over and trashing my radio gear but seeing Dave’s set up I realised I could secure the other end with two simple locating pegs and make it virtually idiot proof. Out with the 3D design and quickly knocked up a tapered peg to fit the headrest sockets. I included a recessed hex to take an M4 nyloc to save having to over tighten a bolt onto wood and split it:

Shortly sent the file to my very generous friend Santa Paul who 3D printed me some and they were in the post!

A quick measure in the car and drilling and job done:
pegs fitted to board
Fitted to top of driver’s seat:
fitted ready to use
Just needs a radio and rotator controller:
ready for radios
