Re: SonoFusion Setup

It is my understanding that the claims of sonofusion have been found to be false. An investigation of Taleyarkhan at Purdue found him guilty of research misconduct and his funding agency (Office of Naval Research) barred him from further funding. Is there something more recent that suggests this can...

Re: Vinyl tubes and j b weld

Vac-Torr is a high vacuum epoxy seal that is designed for high vacuum use. There is a less expensive Loctite product that is an equivalent formulation, but the number escapes me at the moment. Anyone else remember?

Re: Research facility construction

In reference to Richard’s post regarding a separate building for woodworking, I wanted to mention that it is possible to have a woodworking shop and a machine shop coexist with a good dust collection system.

Re: Research facility construction

One other suggestion if you live anywhere near water, be mindful of the floor elevation. A little fill dirt can save much hassle later. When I built my lab building, we hadn’t seen a hurricane in twenty years. I put the foundation slab at grade level, and now I find myself sandbagging every year. An...

You can buy them online precharged with freon for easy installation. Be careful not to oversize the unit; they are so efficient that they don't stay on lo...
