Started off with a 3M x 3M Pop-Up Gazebo ( Argos last year ) to keep the rain off but it blew in from the sides and was dark when the polyester sides were fitted. Had a quantity of twin walled polycarbonate sheets in storage and some left over 1" close celled insulation off-cuts lying in a shed so. The sheet is trapped between some thin timber batons fixed into the 3x2 either side at the base, while each acrylic sheet is held with three cable ties through the gazebo frame at the top.
A couple of lengths of 3"x2" and a roll of Duck Tape later I've now got somewhere to work while it continues to snow. Have to say that it probably wouldn't be that cheap if one had to buy the bits off the shelf.
No wind, have a heater on and been welding / grinding most of the day.[frame]
