Fan Stand or an Excuse to cut some lumber to test the accuracy of my new TS

I am an avid Ham Radio operator, another of my hobbies. Every year on the last weekend of June the ARRL (the US foremost Ham Radio Association) holds a “Field Day” a day were we ham radio get out and test our communication skills simulating an emergency, trying to contact as many USA hams as possible during the allotted time starting at 11:00 am on Saturday and ending at 2:00pm on Sunday, running on batteries or portable generators, some hams and clubs even go all the way to solar or wind power.

One of the luxuries we can have/need especially in hot and humid Florida were in June is easy to run in the 90’s or even 100’s is a Fan.

This year I decided that the small fan I had for las year FD would not suffice therefore I got miself a square box fan, but there is a problem with them, no adjustability whatsoever.

Sooo I have this new TS that I got last month and this could be a test how fast could I make myself a stand that fulfills the needs and has to be easy to knock down for transport.

This is what I cobled up in a few hours using a few scraps of 3/4” plywood, some 2×4 scraps and some hardware.

The 2 uprights are held together by the box that supports the fan and by 2 cross braces on the bottom, all joined with 1/4’’ Carriage Bolts, Fender Washers and Wing Nuts, except the fan box were i splurged and used a couple of 5 Star Knobs that made the whole gizmo look very professional hahaha.

Joinery used, Lap Joints for the uprights/legs, Rabbet and Grove for the Fan Box

I need to add that:
a) the fan/stand combination was a hit at field day with my local club I hang out with, and
b) I love my new TS, the cuts it made on that plywood were so smoth I am and also my buddies very impressed.
Sorry for the side picture but if I rotate it the site will clip it when I upload it.
May be I need some help there on how to do it properly.
Any ways this is my first post/project, I have a few more I need to complete which I will post as they progress.

BTW love the site, very inspiring, even my better half loves it.
