Here you see the results of several hours work...... A beautiful new casting from another source proved improperly patterned at 1:1 - aluminum pattems must be built with a "shrink scale" allowing 1/8" shrink per 12". The filler block for the MK75-78-700 is 18" tall, so was 3/16" short overall. This error required sectioning, welding, and much addional fitting - bummer! It is salvageble however and will be mated to the divider plate and elbows this weekend.
