Re: Nauticat 52 Refit

Core bonded in place. Note the pattern of 3/8" holes drilled for squeeze-out. This prevents hydraulic lock and allows you to see how much squeeze-out you are getting. Drilling holes is an absolute must.

Thanks Cherp.


Using the pattern to cut glass.

I'm puzzled - what is a zero angle stroke?
Also, carbide abrasive blade turned way down - do you mean the speed?

Most jig saws don't just go up and down (reciprocating), they also have an angle off 90 to the stroke and a bit of fore/aft action in the stroke. A really high quality saw like this one allows you to adjust the angle and degree of stroke off plumb. If you give it a lot of angle it will cut very aggressively. If you turn that down to dead plumb it cuts very gently and makes tight turns much easier. So if you set it for a dead plumb cut and turn the speed all the way down, you get great control with no blowout. The other risk free method for cutting urethane core without blowout or problems cracking it (its very delicate by itself) is a utility knife and battens. But I'm cutting a lot of curves on this, so the jigsaw rules. If you put a regular blade with teeth in it, it would ruin your panel instantly.

Re: Nauticat 52 Refit

The "orbital" movement is meant for blades that only cut during the "up" stroke. i.e. with teeth that point up.

Lol! If you built a jig saw blade with teeth that point down you wouldn't be able to hold it on the work piece! All blades except carbide abrasives only cut on the up stroke. All reciprocating saws do this for that reason, they come standard with an orbital stroke. But only really good ones let you adjust it.

Wow. Thanks for the update. I never looked around with my old and trusty Craftsmen. I think its time to move up to the new century.

LOL me more

Here's your impossible blade (the first one on the picture); I used it many times and can't believe you didn't:


A carbide abrasive blade like the last blade in the pic above is another example of a blade that should not be used with the orbital action. I had a Makita jig saw 25 years ago with adjustable orbital motion

you beat me to it.....I've got a lot of the laminate blades I use for various things other than laminates. I like the clean surface on the sidi I'm working on.....could care less about the other side of the piece.

Why in Gods name would you use thirty year old tech like that? We have carbide abrasives, no need to blow out EITHER side of the work piece. Last time I saw a bayonet blade I was hanging rock on houses. Ancient. And if you try cutting serious solid laminate with one, you better hang on! Plus it would instantly destroy the foam core we are talking about.
