Hi all i have access to a roller and want to make a 90degree bend out of 5mm Aluminum .
elbow will be about 800mm diameter with 1 , 2 or more "lobster" segments.
want to make pattern for eack segment before rolling can it be done diy or do i need to get it done on cad and cut.
material ain't cheap so don't want to balls it up
will use me 500amp pulse mig to stick it all together
also own a decent pasma cutter.
the finished thing is called a mailbox or propwash used for blowing sand out the way in shallow water for wreck excavation.
its lowered in front of the propeller which diverts the thrust downwards.
finished thing very similar to large bore sheet galv heating /vent pipe.
cheers elfyn
