why this particular cut?

why this particular cut?Make it simple, make strong, make it work! -
David, what type of cutting wheel are you using and on what rpm? Genuine Dremel?Comment

It's a standard circular saw that produces a kerf of about .025". As I'm cutting polystyrene, I'm using minimum RPM's. Feed is in the direction of saw rotation with multiple passes of very shallow cut till the two halves of the hull are parted. Slow work, but if done right only a cut is achieved and no melting of the adjacent halves. It's a standard Dremel multi-speed motor mounted on a fixture that assures a solid stance while pushing the saw into the work. Work and saw must be rigidly secure to the working surface for this technique to work without flaws.
If cutting GRP, or that funky plastic you encounter if cutting a robot produced hull, I outfit the Dremel with a thin diamond wheel. GRP will dull a carbon cutting wheel in a heartbeat.

Thanks Ray and Dave for the photos, and I'm truly honored that you put mine beside yours for the photos. I have seen the 1993 SUBREGATTA where it first showed up dozens of times. I'm putting them in my Nautilus build-binder. What's really funny about that 1993 SUBREGATTA video, is that I watched it to see the Nautilus, but I was pretty shocked as the original owner (Charly Cleveland) of the Type IX I'm working on (in Builder's Threads) is in that one quite a few times as well the sub. Really bizarre. It was passed on to two other people in-between.I just got back from the SUBEX24 r/c submarine regatta held at the North Lake, Submarine Base, Groton Connecticut. This two-day event was organized by Ray Mason and Joe Oliver and is one of the three out-of-State events I try to make each year.
The weather was perfect; some fine models were on display and operated very well on and under the water; and old friendships re-kindled.
A good time was had by all.
Ray Mason. Some forty years ago this guy designed, built masters and tools and produced excellent GRP kits of the Disney NAUTILUS. Here Ray hovers over two of his completed kits. The one next to him is his own, with removable squid. In foreground is another NAUTILUS, assembled and made operational by Dave 'Jake' Jacobson.
Bob Gato scratch built this simply beautiful 'tourist submarine'. Fully operational, this model alone is a master class in system integration and accessibility; stunning in device utility and simplicity -- he even employs bell type jars as watertight enclosures! He's not only a gadgeteer of the first-order, Bob's also an excellent model-builder as these pictures make abundantly clear.
