To be honest I don’t know what the usual purpose of a self clinching stand off is, but it turned out to be the perfect steel sleeve for the fire button, hence the name Clinch Button. The spec you need is M3 x 8mm long, but there are slim and fatter types and the type you need is nominally 5.4mm wide in the barrel. My measurement of the RS Pro version actually puts them at 5.27mm and so I’ve sized the clinch button for 5.3mm as a snug fit is important.
L = 8mm Thread = M3 C = 5.3mm (sized for a hole 5.4mm)
It’s difficult to get these in small quantities. Walmart sells similar items in 20’s but I haven’t yet found the M3x8mm version. I’ve seen eBay selling packets for £5 inc p&p but the supplier I found had no availability for M3x8mm. The Amazon link above is £10 so we could say these are effectively £10 each as currently I have only one AuthentiKit product that uses these (The Mk1 fire button). These will get used in other products though so you’ll probably uses at least two. As a compromise then I’ve said £5/each inc. p&p
After much searching I found these used by carpenters for clamping a fretsaw table to a desk (see picture below). The AuthentiKit system uses them to clamp the instrument panel posts to a desk or table.
These seem to be most common in Germany and if you can’t source from there you may do what I did which is to buy the clamp with a fretaw table from the wellknown brand Bahco.
The price will vary depending on postage and whether you need to buy the Bahco kit including the mini table at about £8 each. The clamps themselves if you can get them individually are about £2-3 + postage, so let’s say £4 as an indicative price.
The Pebaro model I have designed the mounting system for is the 24/04 version which has the following dimensions. If you need to get different sizes these are the consequences.
Jaw Opening: 40mm (More is fine)
Width: 13mm (14mm would also fit the mounts this slots into)
Metal thickness: 4mm (5mm would also just fit with a squeeze)
Black aluminium pipe 27mm diameter for rig extensions
Product ID: Various
The primary mounting system for AuthentiKit is the two arm monitor stand (ATK500) however most flight controls do not mount directly. They mount to these 27mm tubes which in turn are fixed to the monitor stand at the appropriate height and position to place the controls exactly where you need them.
27mm is not actually that common a dimension however it is a nice compromise between 25mm tube which feels too small with insufficient surface area for good grip and 30-32mm which is a bit too bulky. In the UK 27mm seems to be used in gardening which is where I sourced these black coated tubes in 750mm lengths. In practice 750mm is a little unwieldy and 500mm is sufficient – that is the length SimKitSupplies has them made to.
You tend to get these in packs no smaller than 5 for about £2 which would make them 40p each. In practice you won’t use 5. The Spitfire flight stick uses 3 which makes them effectively 66p each. As a compromise I’ve gone for 60p each.
You can find these easily on eBay and Amazon. You’ll be hard pressed to buy them individually but then you rarely need just one. The Spitfire stick requires 3 for example and I’ve seen them as low as £3.50 for a handful hence the indicative price below.
