Week May 20 was all about crafting out a new wood frame. I learned from the prototype what worked and what didn't and was able to make some changes that improved the quality all around. Started with ACX lumber which uses waterproof glue and has a nicer finish. A template was made and jigsaw used for cutting the circle, now, with a channel down the middle to stabilize the hose.
Week May 27 was about now fabricating the new steel frame as part of the redesigned interior pump and integrated pedal crank. The new Exterior pump design will be very durable as it no longer relies on the frame for rigidity. The picture below shows the steel frame in a jig. Using the jig paid off and my welding is getting much better. All closed ends and no seams. Looks fantastic.
