Hello all,

I live in Lisbon, and camera companies here don´t have much in terms of camera accessories and brackets for use with steadicam. I m talking about low mode brackets, hardmount options and such.
Since renting out from abroad can take a few days, and buying everything is just too expensive, I am thinking about haveing some brackets built locally.

I finally found a machinist that works alumnium with the precision our work requires. But I couldn t answer his first question:

What kind of alumnium?

Is there a specific kind of alumnium used in the manufacture of our gear?

Also, is there a screw brand that s more adequate than other?

Any light on these subjects is deeply apreciated.

Thanks in advance,



Leandro Silva

Hi Leandro!

I know that two of the best resistant Aluminium on the planet it's the 7000 series (call ERGAL 7075) and the 8000 series! The first one, are using also for building the airplanes!

6061T6 and 7075t6 are all that you need. You don't need to bother with 8000 series

You want to make sure to use properly rated hardware. The cheap unrated stuff shears way to easily. In the metric world most of it will be stamped with a number like 10.9. Some more info is available here: http://en.wikipedia.org/wiki/Screw For stuff not holding much of a load I like to use a decent grade of stainless steel fasteners to prevent rust. For load bearing items I go with the higher strength ratings and treat heads with corrosion-x to prevent rust.
