| Description for Image 1: First of all, the toe brake mechanism I'm experimenting with. | |
| Description for Image 2: its basically a L-bracket mounted to the pedal plate. It is important that the braket is mounted such that the pivot point where the vertical rod is connected to describes a circle when the breke is activated. Otherwise that mechanism will lock either when braking or when moving the rudder (probably both) | |
| Description for Image 3: the lower part of my test mechanism for the toe brake. Later, the black rod will have to be able to move up and down during braking. | |

| Description for Image 6: | |
| Description for Image 7: the thing flat on the floor | |
| Description for Image 8: brake/rudder pedal plate and L-bracket of the brake mechanism | |
| Description for Image 9: maybe this pic makes it clearer: the hole on the bracket thru which the vertical rod is connected must always have the same distance from the center of the threaded rod (rudder pedal), otherwise its not gonna work right ! | |

| Description for Image 13: This starts a sequence of how I built my rudder pedals. Here is an overview of all parts used. I also put a meter next to some parts in some pics so you can see the sizes. (And yes, I took the thing apart for this gallery :-) | |
| Description for Image 14: Lets start with the pedal plates and the threaded rods onto which they'll be attached. | |
| Description for Image 15: | |
| Description for Image 16: | |
| Description for Image 17: | |
| Description for Image 18: Its a M12 threaded rod. M10 would also work fine. | |
| Description for Image 19: The vertical rudder part and the links to the crossbar. | |
| Description for Image 20: Its a 2x2cm square Alu pipe | |
| Description for Image 21: | |
| Description for Image 22: the link to the crossbar | |
| Description for Image 23: Thats a M3 screw and nut holding the rubber band. | |
| Description for Image 24: | |
| Description for Image 25: Sorry for the blurry image, it should read about 11cm total length for the link. | |
| Description for Image 26: And about 9cm between the holes | |
| Description for Image 27: Distance from the upper 12mm hole to the 3mm hole for the link is 7.1cm (disregard the rightmost hole, thats from an older, longer version) | |
| Description for Image 28: Its a total of 14.2cm between the upper 12mm hole and the lower 10mm hole and pivot point and 6.8-6.9cm between the pivot hole and the 3mm hole for the link | |
| Description for Image 29: The 3 brackets mounted to the base board | |
| Description for Image 30: | |
| Description for Image 31: | |
| Description for Image 32: | |
| Description for Image 33: Now a couple of pics with closups of the crossbar and where it connects to the pot | |
| Description for Image 34: The yellow piece is PVC, better would be some Delrin or other plastic washer. | |
| Description for Image 35: | |
| Description for Image 36: | |
| Description for Image 37: | |
| Description for Image 38: | |
| Description for Image 39: | |
| Description for Image 40: there are 2 metal washers that sandwich around the L-bracket onto which the whole thing is mounted | |
| Description for Image 41: | |
| Description for Image 42: | |
| Description for Image 43: | |
| Description for Image 44: The yellow gear wheel has a crack because I tightened the nuts too much :( But it still works. :-) | |
| Description for Image 45: two screws, one as the pivot point, the other prevents the gear wheel from moving relative to the crossbar. | |
| Description for Image 46: its about 20.5 cm long total, same material as the vertical rudder arms. | |
| Description for Image 47: and about 8.0-8.2 cm from the screw to the center/pivot | |
| Description for Image 48: same here. (actually I made a little mistake here and this side is nearly 0.5cm further out from the pivot | |
| Description for Image 49: | |
| Description for Image 50: seen here is the lock screw through the gear wheel. | |
| Description for Image 51: | |
| Description for Image 52: Starting to reassemble, step by step. | |
| Description for Image 53: | |
| Description for Image 54: | |
| Description for Image 55: This actually needs some plastic washers (right and left of the vertical rudder arm) | |
| Description for Image 56: | |
| Description for Image 57: the crossbar. about 9cm above the base board is where the link will sit. | |
| Description for Image 58: | |
| Description for Image 59: sliding on the link | |
| Description for Image 60: putting the M3 screw in its hole. It will NOT have any kind of nut put on through the vertical arm, the rubber band will hold it, while still being flexible enough | |
| Description for Image 61: But wait... don't push it in yet, we need another measurement :) Its about 9.5 cm from the base board to the hole for the link | |
| Description for Image 62: push the link on the screw on the crossbar | |
| Description for Image 63: and fasten with a nut (but not too tight, it'll have to be able to move a tiny bit at larger rudder deflections. | |
| Description for Image 64: the more horizontal the link is when the rudder is in neutral, the better | |
| Description for Image 65: the link sits about 9cm above the base board | |
| Description for Image 66: starting to attach the M12 rods | |
| Description for Image 67: | |
| Description for Image 68: trying to give you a picture of how I imagine the toe brake mechanism (the pedal plate is not attached yet, just held in place for the pictures) | |
| Description for Image 69: | |
| Description for Image 70: max rudder throw in one direction | |
| Description for Image 71: and the other | |
| Description for Image 72: the same again from the top/front | |
