Tub sides glued to bulkheads.
Forward tub sides hanging past end of jig.
Tub with aft bottom in place.
Make sure that the rear 3 bulkheads have the 2
little holes on the right.
These are for the brass cooling water tubes
installed later.
Once you are happy with the fit of the bulkheads
in the tub sides, glue them in with CA or epoxy.
Use the square provided in the kit to ensure each
bulkhead is perfectly square.
When cured, flip the tub over and lightly sand the
bottom.
Now is the time to use your tub jig. If you don’t
have the ability to make an aluminum jig, use a
pair of straight, thick wooden sticks. Leave these
clamped to the sides while gluing the aft bottom
in place.
Put a layer of waxed paper over the jig.
Put the tub aft bottom in the jig and set the tub
onto it.
Fully clamp the tub sides to the jig.
Check all around to make sure that the tub fits
properly on the bottom sheet.
Remove the tub from the jig in preparation for
gluing.
Using epoxy, glue the tub aft bottom in place.
Make sure that the bottom extends to the front
bulkhead. It should cover the full 1/4 inch
bulkhead.
Leave the overhang at the rear of the tub. Do not
sand this off.
If you use anything other than aluminum angle,
make sure that the bottom sheet doesn’t move
sideways while it cures.
This can occur if you use angle iron, or some
other angle that doesn’t have a sharp angle.
It may be a good idea to draw a line on the
bottom, along the inside of the tub, to be sure the
bottom sheet has not moved.
