I have followed your work for years and dream of having such standards and quality of build in my workshop.  Your site seemed to go stagnant for a while and I stopped coming back to it.  I am so glad to see/hear that you are plowing on!  And I see I have much to catch up on and look forward to many hours of study.

 

Also thank you for the oven ideas.  Unfortunately, most of my parts are very long.  I was hoping I could put the beams and rudders and other parts inside the leeward hull and cover it with plastic and blankets and throw a little fan/heater inside... kind of convection oven concept.

 

Thanks,

Dennis

http://www.fram.nl/workshop/mainhull/album/Portsidecarbonanchorsandbeambulkheads/photos/photo1.html is a photo for the receipt to make a simple oven. This one is made of standard sieze (60x120cm) polyurethaan insulation amterial (thickness I think 7 cm), so for a box oven you need 5 sheets. Heat by two light bulbs and a plate above to spread the heat (together with some bricks) Started with one 150W halogeen bulb, wow, 250C much too much, then 2x75W light bulbs resulted in 85-90C, 2x40W bulbs became 60-70C and 2x60W bulbs about 70-80C (roomtemp. about 20C)

 

At first I started in the admirals's oven

now we all know that one need a very understanding wife when undertaking a serious boatbuilding project, but one can go too far ....

so, not a good idea and the DIY oven with the light bulbs is much easier.
