Pedals

The Pedal System is based on the same mechanic like the Yokes. I use Gas springs and the Metal T-pieces for the mechanics.

On this page you’ll find the following:

  1. Information about the Construction of the Pedals itself

I decided to make the Pedals itself from Aluminium, On the positive side – i can make the parts on my CNC machine and the whole System will not be too heavy when it is finished. The negative side – i need to get external Service to weld the parts together, because i can’t weld Aluminium at home. And one great Thing – i tried to cut the Aluminium parts on my Metabo KGS 216M Mitre Saw -and because of the hard metal inserts of the blade tips – it cut like knife through warm butter…. Big time saver to lenghten the Aluminium parts on the Mitre saw instead by Hand….

Please have a look at the drawing of the Pedal pieces. ↓

And this is how the parts came of my CNC Machine ↓

These are the parts as they came out of the CNC machine. It took me 2 days to make them. 3 End mills broke during that process. When i put the parts to the Company which welded them together – the owner asked me why i didn’t send him the AutoCAD files – it would have cost him 30 secs to make them on a Trumpf Lasercut machine (25m/min feedrate – compared to 150 mm / min on my machine)

↑ This is how the parts look in assembled condition. The parts came out very nice. NOTICE: You should use a drill press to press in the bearings – not a hammer.

The mechanic for the Pedals is based on the same System as i used ot for the Yokes already. The movement of the parts is translated by a T-Piece which is hold by two flanged bearings. The movement is picked up by Gas springs which provide the centering and push Forces.

The Travel way of the Brake movement is limited in a very easy way – i put a blocking ring around the the Piston bar of the Gas Spring. This way i can easily fix the travel way of the Brakes. ↓

The Threaded Bars have been split into two pieces and are connected by a simple metal plate with 10 mm holes. This way i can make the fine adjustment of the Pedal Position… ↓sd

The Potentiometer for the Brakes have been attached to simple holders with cable binder. The holders itself are RIVETED to the Pedals. I discoverd that RIVETING is a very elegant way to attach flat items to other flat items. It is much better and faster than cutting threads and using screws. The riveting tool is use costs approx. 30 € and helped so much. ↓
