[bolger] Re: cutting bulkhead openings?
You might want to try a special blade in your sabre saw. I got some at
Sears a long time ago. I have one left, and it has the number 28761 on it.
I don't know if they still sell them. It makes the cleanest cuts in plywood
you can imagine.

Leander - I forgot, are you building a schooner? If so, instead of cutting
the holes to plan, you ought to think about cutting them for sealing deck
plates for the extra flotation. It might make the difference between
bailing on the water and dragging to the beach to bail (see my site).

Ok, I'll jump in too. I vote for the router approach, but you can also
use a smaller disk as your guide. Take the distance from the edge of
your router base to the router bit cutter, subtract that from the radius
of the hole you want to cut. The remainder is the radius of the circle
you want as your guide. You can make this out of wood (hole saw or
whatever) or find a round lid, metal or plastic, that is close enough.
Screw it to the center of the hole you want to cut, drill a starter hole
for the router bit, then keep the router presed against your pattern
while you cut the circle. (Whew, I got tired just describing it, maybe
the swing arm would be easier.)

A good, fine blade with some tooth set is a start. You can also score
around your line first with a knife, cutting through masking tape is second
choice.

Plans for the folding schooner call for round cut outs for the
bulkheads about9" in radius. Noticed the absolutely clean cut outs on
GHC's Light Schooner. I have an old Sears sabre saw and have been able
to do a relatively neat job on the bilge cut outs with a nice new
makita blade but I am daunted by these big holes. I figure I can lay
them out with a string but am worried about how to get a clean cut. Any
advice would be appreciated.

bulkheads about9" in radius. Noticed the absolutely clean cut outs on
GHC's Light Schooner. I have an old Sears sabre saw and have been able
to do a relatively neat job on the bilge cut outs with a nice new
makita blade but I am daunted by these big holes. I figure I can lay
them out with a string but am worried about how to get a clean cut. Any

Make a radius arm, circle cutting jig for your router. Use a thin strait
cutting
bit.
