RE: Nuarc Frame (More Info)

Yes, all you need is plain float glass. Every decent glass shop in
town should have what you need in the necessary dimension. Just take
your your measurements to a shop and in most cases you can get it cut
right away, at least that is the case where I live. Have them smooth
the edges because the edges of cut glass can be very dangerous and
even getting it home and in the frame could be risky.

I don't know much about your pump but you can get an excellent Gast
oiless rotary vane compresssor/pump that will work fine with vacuum
pumps up to about 23X29" for around $40 from C and H Sales Company in
Pasadena, California. Their Stock number for this part is PC2050. The
hardware stores also will have step-up and step-down adaptors that
will allow fit between uneven end parts.

As for tubes you can find what you need in local auto parts stores or
even in places like Lowes or Home Depot. You don't need anything
special as most plastic tubing available, clear or black, will be
more than adequate for your needs.
