Jonas Romblad's Mold
Ever wonder how those beautiful Jonas mtas were made? Jonas
was kind enough to provide me with these great pictures of one
of his molds to share. A total of 371 boomerangs were made with
this mold, and it's still in great shape! His comments:
- The mold is fiber glass and epoxy with an epoxy gelcoat and
steel tube reinforcing structure.
- The gelcoats on top and bottom mold half are different types
and colors since the top had to be reworked and I ran out of
the first type - nothing more scientific than that.
- Please remember this is a production type mold. For smaller
series and experimenting this kind of mold is overkill!
