3/1-3/7

This week has been successful relatively speaking, TechShop extended their dates of availability until the 23rd of March which gives us more access to a reliable welder and welding tools. So far, 3 corners have had all the brackets welded to the lower tracks. Welding the upper guideway to the bracket has proved to be very difficult as the cast aluminum, guideway, and filler rod all have different melting temperatures. The guideway and the bracket are also so thin that the welder is basically melting them into oblivion. Jez and I have been looking into aluminum based adhesives. We have not yet found anything that would be economical in quantity. We also expect that if we use an adhesive, it would become easier to build and make sure all the components are within tolerances.
