Fastening chocks.

I finally got around installing runner chocks to runner plank. I started by fastening chock for one side. At this point I only needed to focus on trying to get it in 90 degrees angle towards runner plank.

Here I have installed runners in chocks as that is needed for measuring to make sure runners are in parallel.

The left side runner is fastened with one bolt to enable adjustment. I use a measurement stick to measure that runners are parallel. Once runners are parallel the two last fastening holes are drilled.

 It would probably be possible to use laser or something else fancy to measure parallelism! An advantage of this method other than that it is very simple is that it is the parallelism of the sharpened edges that is measured. 

A jack is made with a saw to measurement stick straight above the runner axle bolt.After this the measure is checked at forward and aft part of runners and adjusted until measure is same everywhere.

After checking the measures its time to drill the remaining fastening holes.

Runner plank ready!

Not so much to say about front runner chock fastening! M8 bolt holding chock in place and acting as shaft for steering.
