<p>[QUOTE="calcol, post: 10981510, member: 77639"]Can speed up the process a lot if you have a vacuum pump and chamber. Applying a little heat (100 F) at same time can make it even faster. Be careful about a homemade chamber … don’t want an implosion. I’ve made chambers from 4” schedule 40 PVC pipe, which is strong enough. With schedule 40 pipe, pressure rating goes down as diameter goes up, so think twice about using larger pipe.</p><p><br /></p><p>Cal[/QUOTE]</p><p><br /></p>
