Adjusting the pole for each layer
See below for the theory of adjusting the pole for each layer while going through the ramp area. We have used the 8 ft. igloo as an example.
When building the igloo, the pole length adjustments are made on the lower pole (the 8 or 9 ft. pole, see below), these are the numbers you can read because they are on the top of the pole assembly and they are visible. The numbers on the upper pole (10 ft. pole, see below) are on the bottom of the pole assembly and not visible.
In the three block ramp, there needs to be an in-between adjustment between the first layer and the second layer. Adjust the pole length when directly on top of the center block of the ramp. When adjusting the length, go from hole 1 to hole 3 for the center block of the ramp and then go to hole number 2 on the next block when you reach the third block of the ramp, the second layer. When going from layer 2 to layer 3, the adjustment isn't a very big adjustment so just make the adjustment on the center block of the ramp.
From 3 to 4 is a bigger adjustment so stop in hole 1 for the center block of the ramp and then adjust the pole to 4 when you are on the last block of the ramp.
From 4 to 5 is different because
there is a greater distance between 4 and 5.
