Machined Parts

Aerographic can supply a range of machined parts as follows.

Control Column Torque Tube Blocks. 

Manufactured from HE-30TF Material (6082 T6) to Pitts S-1S dimensions. 

Either plane bearings (Pitts S-1C) or to fit KP6 bearing (S-1S). S-1S type requires one of each, see photo.

Note vertical clamping bolt holes are drilled undersize to allow for final through-drilling on installation.

Flying Wire Spears 

The design of these flying wire spears has been developed over a number of years. They are manufactured from HE30TF (6082 T6) aluminium bar, with nylon inserts to support the flying wires and prevent galling. 

Spears are designed to be fitted to the Pitts S-1, although the design can be adapted on request to suit other aircraft, please provide dimensions. 

Supplied slightly over-size. Will require final trimming to suit individual aircraft.

Pitot Tubes

Pitot-static tube suitable for installation on aerobatic aircraft and other homebuilts.

Supplied with circular spar attachment block to give a wider base to provide increased support for the pitot tube. Block drilled to accept standard AN pipe fittings.

Axle Spacers and Spat Support Blocks 

Axle spacers manufactured from 6082-T6 material to suit 5-00 x 5 axles and Cleveland wheels (1 3/4" outside diameter, 1 1/4" internal diameter, 1/4" thickness).

Wheel spat support manufactured to Pitts S-1S drawings in 6082-T6.

Note that none of the above parts are TSO'd as these products are specifically aimed at the homebuilder.
