Erez,
I have a vacuum pump made from a car compressor and industrial sewing machine. Just take the machine head off and drive the compressor with the machine motor. Still where possible I use pressure instead of vacuum. This is the same with the spi pole. I've never used heat shrink.
Basically I cut an aluminium tube lengthways to make a mould. Surface the inside with shiny packing tape. Coat this in PVA as a release. Make ends up. Make a bag from plastic and packing tape. Lay carbon layup in tube half. Place bag inside. Fold layup over the bag. Put top on. Do up hose clamps every 150mm to hold together and then inflate to around 35lbs. I have gove a high as 50 lbs but that does tend to push a little too much resin out.
The end result is a shiny black carbon tube. I may have a proper right up somewhere with more detailed instructions if you are interested I'll see if I can find it and mail it to you.
As far as building the Blade the Okume ply really is the trick.
I don't think you will get the weight and strength with very thin ply and glass. But let me look into it and get back to you.

Regards,
Phill
