The engineers at Nor-Cal Products will work with you to reduce the cost of a custom-made chamber. Two easy methods to substantially reduce costs are: Reduce the tolerances on the drawing. Tighter tolerances = more production time and higher cost. Simply changing the default tolerance values in your CAD program can reduce costs immediately. Use standard components instead of custom-drawn parts. Standard off-the-shelf parts cost less. Working with standard fittings, tubing, elbows and diameters will reduce the amount of custom work required on a chamber.
