How to make a Canopy with no vacform

Post by roo Hawkins »

I have been asked a few times how I make my canopy's so I thought I would start a separate thread on how I do it. It is not has perfect has a vacform but you can still get good results and if you are lucky you can get a perfect one. . there is a pit of a kack of it and my need a bit of practice . I hope this will encourage some one to have a go . the p.t.g.e I use is 1 mm. First you will need a wooden stand .then sit your plug on to it

Then you need to remove any dust and then polish with cooking oil this help the petg to slide.

You then need to cut the ptge sheet 4 or 5 in oversize and fix it to 4 wood battens with wood screws. Leave the plastic protective backing on this will be removed when finished and stops you scratching the petg when pulling the plug

You then need to heat up the plastic I use a camping cooker it needs to be a large heat source. And wearing gloves I heat it up in a circular movement but not two close to the heat source. The petg will go soft when it starts to shrink it is ready. Very quickly press it down over the plug in the centre and hold it down DO NOT REMOVE TILL IT IS COLD.

Some times depending on the shape of the plug it will go in one go more the often it will cull up at the ends. To sort this you need to sit with one leg each side like you are riding a horse. Then with a heat gun reheat that area till it goes soft and when it start to srink you need to pull and hold down using a pice of leather the wat till it is cold if you do not it will get bumps in it and if you heat the bump and hold it down it will only come back. The only way to get them out is to reheat and stretch them out

Quick question.. (from a numpty)

When you attach the battens to the PETG, these are only shown down the sides, you don't form the battens into a rigid oblong? Is that correct?

Thanks
