I constructed
this several years ago, from
thick wall Acrylic.
3 inch Outside Diameter, 1/4 inch thick wall
2.5 inch Inside tube, 1/32 thin wall
1/2 inch thick flat sheeting.
"Under Construction"
Clear Lexan* Polycarbonate 9034 Sheeting
Lexan* 9034 uncoated polycarbonate sheet is the standard
grade of Lexan* sheet for transparent protective glazing. High-impact Lexan*
9034 sheet can be utilized for primary glazing, or on either side of
existing glazing for economical protection against breakage or intrusions. A
better insulator that glass, Lexan* 9034 sheet contributes to lower energy
costs. It is virtually unbreakable, making its products an excellent
condidate for safety in areas where parts may be exposed to high impact.
Will withstand -40° to 180° continuous and 250°F short term with no load.
Forming temp. is approx. 375°F. Excellent thermoforming characteristics.
Cold form radius no tighter than 100 times the thickness of the material.
Superior fire performance. UL listed for burglary resistance. No UV treated
surface. Typical applications include interior applications for industrial
and commercial, interior glazing in security areas, fabricated parts,
industrial machine guards and much more. *Lexan is a registered trademark of
General Electric Company.

How-To build the "Yet Another HHO" Flow Meter
Technically, this device is one form of an Eudiometer.
Materials List:
1 - Clear Polycarbonate Tube Lamp Guard by Westinghouse. For use with 48"
T12 lamps. (with endcaps)
1 - 1 1/2" thinwall PVC pipe (suggest 3 or 4 feet in length) Inside diameter
MUST be only slightly larger than the clear tube above!
1 - 1" PVC pipe any gauge (suggest 3 to 4 feet in length) Must match the end
caps selected below!
2 - 1" PVC end caps (rounded ends rather than flat recommended) Outside
diameter MUST be only slightly smaller than the clear tube above!
1 - 1 1/2" to 3" adaptor (this will become the base)
1 - 3/8" 90 deg nipple fitting. (suggest Nylon rather than Brass)
1 - Roll of 3/4" 3M brand Electrical tape. suggest black, but any color
should work. (Needs to be soft electrical tape that can stretch easiely
without harden over time.) (Lowes)
A length of 3/8" tubing as the feeder gas line. Any suitable length will do.
MUST be the same size as the fitting mentioned above. (Lowes)
Some good quality 40mil or better clear packing tape. To seal the end of the
Clear Tube above. (Staples Office Supply)
