I needed to bring some bible characters back from the past (as you do), and so obviously needed a time machine. As there were none on the open market I decided to make one.
You will need: - Several lengths of wood. I used 2x4cm baton, and 5x5 cm for the base. - Coat hangers. - Some bolts and brackets (just what I had to hand) - 8 large butt hinges with removable pins. - 2 smaller hinges. - 2 small pulleys. - Some suitable thin cord. - Black paint. - 6m of Velcro. - 8m of suitable material for a covering. - A big bright light source. - A blue revolving light. - and a smoke machine...
The design principle was that this should store flat. Time machines need to be at least as big as the people they are going to bring back from the past or future.
The frame is made of wooden baton and hardboard corners for strength.
The hardest part of the frame is getting the geometry right. I used a cardboard model to work out just how big everything would be. (Unfortunately I don't have a picture of that). The process is to make panels out of card, and fit them together using a bit of tape so that you can see what the shape will be like in 3D. You can then measure the dimensions and angles. the dimensions you would scale to something approximating the size you want.
As an example: a piece of card for the door panel that measures 18cm, scaled 10 times would be 180cm, or 1.8 Meters.
Once you have worked out the lengths you can get your baton. In the UK we can get this from DIY shops in bundles of about 6 lengths each 2.4 meters long.
Lay the cut lengths out on the ground and MEASURE THOSE ANGLES. this is vital, as when you come to screw everything together, those angles need to be correct, or the whole thing will be wonky.
