Engineering tools
Two calculators from our own shop floor.
Built for estimating inside the works. Free, no sign-up, and they run entirely in your browser — nothing you type is sent anywhere.
Calculator

Rings and pipes, blocks, and stepped shafts of up to four diameters, with an allowance for forging weight loss. Updates as you type.

CATALOGUE
Prefer it on paper? Grades, equipment, part families and contacts are in the capability catalogue (PDF).
A CAVEAT
A weight from ideal geometry is not a drawing weight, and matching chemistry is not an approved substitution. When it has to be right, send the drawing.
Beyond the calculator
We can quote the whole part, not just the weight.
Send the dimensions you just worked out, with the grade and quantity, and we will price the finished part.
