DIY Collapsible Ice Fishing Shelter: Build Your Own!

With winter coming fast and the lakes starting to freeze up, I remembering reading about a collapsible ice hut some years back that you could build for under a hundred dollars. It may cost a little over a hundred dollars now, but not more. I dug up the material list and diagram. I thought that some of the members or views may enjoy this project well waitting for the ice. This hut will allow you to be more mobile on the ice chasing your favourite fish. I beleive that it would be a great place for the kids to warm up on those cold Feburary or March morning until the sun comes out and warm things up. Here is a list of what you will need to build your own collapsible fish hut.
Three sheets of 5/8 inch plywood
1   40 inch piece of 2x4
1 sheet of canvas or trap measuring 8 ft by 15 ft
1    7 ft-long 2x2 (centre beam)
2  Door hinges
Door Handle
Door latch
6 hinges
Screws and staples
Paint or stain
Metal brackets
1 additional hinge for trap door
Sliding lock for trap door
   You will also need a heavy-duty staple gun, jigsaw, skill saw, sharp knife, pencil, string, measuring tape and cordless screwdriver (drill).
   Construction:
-Place one sheet of plywood flat and screw down the 40 inch piece of 2x4 across one end. This will raise up the back panel so the panels overlap when the ice hut is collapsed (diagram 1 & 2).
-Centre a mark at six feet on each of the remaining two sheets of plywood. Measure down 20 inches from this mark, gently tap a nail and using the pencil and string, scribe an arc on top of each panel (diagram 3). Remove the nail and cut out the arcs with the jigsaw. These will be the wall panels.
-Next, measure a 2ft by 4ft doorway on one panel. this will be the front. Leave a 5 inch sill on the bottom (diagram 4). Cut out the door and reattach with hinges, attaching handle and latch where appropriate. Cut out a porthole at one or both ends of the shack for good ventilation.
-Using three hinges for each panel, fasten the front and back panels to the floor from inside the hut. The back set of hinges fasten to the top of the 2x4. Erect the panels and wedge the centre beam in place with (7ft long 2x2). I suggest installing brackets to secure the centre beam. Staple canvas or trap in place (diagram 5).
-Cut either a round hole or construct a 10 inch by 14 inch trap door with a hinge and sliding lock on the floor. Now either paint or stain the hut to seal the wood.
   Now that you have one built all you need to do is hook it up to your quad or ski-doo.
