Fellow roboteers,

After 5 years doing spinners and some wedges in Brazil, I decided, since moving to the UK, to do a pneumatic featherweight.

Almost all components are defined and some were already bought, but I am heaving trouble defining the adaptors and fittings. What do people normally use for full pressure? I thought about using hydraulic adaptors from Burnett & Hillman rated for 350bar on a Aluminium manifold.

The system will be a custom, 65mm bore ram, with integrated valve. So the fittings for the Buffer tank will be 5/8~3/4 BSPP and for the main cylinder, to avoid icing, I thought about G1/8 or 1/4.

What are the experienced builders opinions on these matters?

Also I would like to take this opportunity to thank Woody for his resourceful website and all the forum members for the shared knowledge.

Regards,
Eduardo
