Yippee! My spruce tree finally grew! Went down to Aircraft Spruce andpicked up my rib capstrip and plywood. Time to make some ribs! Wifealso said OK to new scroll saw. Another yippee!On a safety note, any airplane using bungee cords as shock absorbersshould have a safety cable to prevent collapse of the gear if the bungeegives way.________________________________________________________________________________

Ian,When you say bench saw is that the same as a portable table saw? I want tomake sure I get the right tools. Also, I'm not sure I know what a plainerblade is. Is it just a smooth cutting blade? Sorry to ask such simplequestions.Thanks,Brent Reed-----Original Message-----

The bench saw was out of Sears and is a portable unit that you can wheelaround the workplace easily. The planer blade is a thin kerf saw (steppeddown) for about 2 inches. It gives a satin smooth finish that needs noplaning. The blade is ridgid enough that there is no wobble. I can't readthe specs on it other than it has 200 teeth. after doing the whole plane,it is still extremely sharp. However, it does not see plywood or otherdulling substances.

However, I've found that the bandsaw has been invaluable in the shop. I bought a Sears tilt-head, two speed bandsaw a couple of years ago. The tilting head allows for a huge table area compared to other band saws and the 2 speed pylleys allow a metal cutting blade to be used. Most of the fittings on my Christavia were cut with this saw. The slow speed is still a little high for metal cutting but it just means buying a couple of more blades.Just my $0.02Ken________________________________________________________________________________
