DIY Packraft construction & packing notes

This post is a work-in-progress documenting changes or additions made during the construction of four Telkwa packrafts purchased from the awesome folks at DIY Packraft. DIY Packrafts are extremely well designed and the kits assemble exactly as demonstrated in the excellent videos and printed instructions.  My intention is to substitute the  Leafield D-7 inflation/deflation valves to replace the supplied Boston valves.  While heavier and more bulky my experience is that inflation/deflation is much quicker due to larger porting, are easily cleaned, and are field-replaceable without thermal welding.

There’s really only one tool that I’ve found that materially improves assembly processes.  It’s a small stainless steel mixing bowl with a flat bottom slightly wider than a typical welding area.  To the bottom of the bowl two parallel strips of 3M double-faced window film sealing tape are added just outside of the working area.  This easily removable tape typically has enough adhesion to complete the welding of one tube segment.  Removal and replacement of the two tape sections takes about a minute.
