Fabricators Handbook

Gellis apps

About this app

Sheet metal pattern development tools for cones, segmental bends, set on pipes.

Plus flange/ tube tables, various calculators and more.

This could be the most useful tool in your toolbox.

As a fabricator of 45+ years, the last 30 or so as the workshop manager, I have constantly used trigonometry etc. to calculate cones, segmental bends and much more. Nowadays I am constantly asked by the fabricators to calculate developed lengths etc. to save them the time and effort of laying it out. I have developed this app so that they can do it for themselves and therefore save “MY TIME”.
The Fabricators Handbook is a collection of apps useful to the experienced fabricator and novice. Various pipe and cone developing app for wraps and plate. Tables for flanges, tube schedules, elbows and tees, as well as metric and unc drilling / tapping sizes. Calculators include, Angle Calculators to enable the fabricator to layout accurately small or large fabrications, Pitch Calculator for PCD's and straight pitches, Diameter and Circumference calculator for working out the required developed length for rolling and a Bisecting Chord calculator that works out the inside or outside radius of an object using a straight edge and a ruler. How to examples are available where needed.
I hope that from your feedback/comments I will be able to add extra relevant features and amendments in future editions.

Ratings and reviews

This is the best app ive seen in a long time .... been in a fabrication shop for thirteen years now...only on guy knows this kind of layout, and won't show any of us younger guys....thank you so much!!!! Very useful!!!

Been a structural plate fitter/welder for 22 yrs and honestly there's so much we forget from trade school and this gets us outta a bind pretty quick. Thanks. Im old school so I never really carried smart phones or grew up with them like the younger guys but I keep a tablet in my toolbox now

Great app. Would be nice if you can add sizes up to DN600 to bigger. An option to print or email developed shape would be better
