Black felt strip 50mm wide x 1mm thick

• Manufacturer: Various
• Product ID: Various

AuthentiKit designs use this felt strip in throttle quadrants and other places where a lever needs to slide against a plate. The felt adds some friction and keeps the action smooth.

This Amazon link lists the felt as 0.04″ x 1.96″ which is basically 1mm x 50mm

IMPORTANT: It is important that the felt is just 1mm thick and no thicker. Expect it be to around 1.1mm when measured with calipers including the non-stick backing paper. I have heard that the above product from Amazon can vary and someone found that their felt was 1.3mm which was too much when used in the P40B and caused the levers to stick. In order to have a definitive way of measuring thickness I have made a set of clamps which you can fit over calipers creating a surface area of 20mm x 30mm which can be used to lightly press against the felt. Download the clamp design from this link. This is how it should look when you use them.

You only need small lengths and you should be able to by on eBay by the metre though suppliers come and go. I’ve seen it for around £5/metre inc. postage

Wider is fine as you cut shapes out of it. You may be happy with grey rather than black though black usually looks best. 1mm thickness is essential.

SP40 Black silicone rubber tube, internal diameter 4mm, wall thickness 1mm

• Manufacturer: Various
• Product ID: SP40

This tube is great for running up to 3 wires through to provide a more period looking pneumatic/electrical connection instead of revealing multi-coloured wires.

Supplier Links

Some tubes have a matt finish. The shiny finish looks best.

It needs to have an external diamater of 6mm and you’ll have problems if the wall diameter is not 1mm – the tube will either kink too much or not have sufficient space inside to run the wires.

Nitrile bonded self adhesive cork disc 18mm diameter x 1.5mm thick

• Manufacturer: Various
• Product ID: Various

This disc provides most of the friction when rotating a small lever such as a flaps lever. Nitrile bonded is preferred as normal cork is prone to squeaking.

Supplier Links

I found a supplier on eBay in the UK. There should be other similar suppliers around the world otherwise purchase some 1.5mm nitrile bonded cork with self adhesive backing and cut out an 18mm disc.

Try to avoid normal cork but if its your only option you could try it. A thickness of 2mm is often too much for certain uses so be sure to find 1.5mm thickness.

You only need a few cm of this but you’ll probably have to buy at least one metre. The product above is 5m long and costs £2.60, but you’ll probably find shorter lengths on eBay for less, hence my indicative price of £1.

You could use anything wider and cut it down. It does need to be about 4mm thick though to get a nice resistance.

PH1 Phillips head screwdriver bit

• Manufacturers: Various
• Product ID: Various

This is the perfect sized bit for M4 phillips head screws which are used so much in AuthentiKit designs. It is much easier to assemble things with the right bit as you can actually hold the screw with it. It is also easier to use this bit with the 3d printed mini screwdriver handle (in the downloads) than a full size screwdriver
