Most of the holes drilled.
Preparing welding.
Same procedure for front runner.
Welding outside in -10 degrees Celsius.
Front runner chock is still missing the "arms" to fasten steering lines in and hole for steering shaft.
Rear chocks are basically ready. I'm still considering if I should build a bracket that would grab around the plank. The idea is that it would take up the sideways forces on chock during sailing helping to keep runners in parallel. Alternative is to have a turnbuckle connected between plank and rear chocks this would also allow some adjustment if parallel alignment between runners is off.
This was how I planned to attach steering line arms originally but the steering radius would become to big as the arms hit the springboard limiting the steering too much.
Determining how much the runner is able to turn before hitting the chock. The front runner is able to turn around its axis a a little bit more than 20 degrees (+- 10 degrees from level) in total and the rear runners about 17 degrees. Building instruction says that runners should be able to turn around their axis between 10 and 20 degrees so I guess this is OK.
Steering arms still not welded.
