<As Larry mentioned in his post, you need some sort of bleed valve.
Shouldn't be too hard to fabricate.>

Thanks for posting the description of a vacuum frame.
What is the purpose of the bleed valve? Do you need a special vacuum pump,
or can you adapt an old cannister type vacuum clener?
Regards,
John
