7/31/20 My 1/8 BSP (British Standard) die arrived today so I changed the 1/8 NPT to 1/8 BSP and fitted to the Parking Brake valve. The Throttle/Brake assembly was completed with the cable bolts and brake line fittings left finger tight for final installation. 7/26/2020. Added the 1/8 NPT fittings to the hand brake cylinder but I could not fit to the parking brake valve. It was a different thread. An email to the factory got the following response: >>>The thread on the fittings is 1/8” NPT and inside the valve is 1/8” BSP – the 2 threads are almost the same but don't quite fit. What we do is get a 1/8” BSP die nut and clean the thread of the fittings. Apologies – it should be in the manual.<<< So off to Amazon to get a BSP die. 7/24/2020 Assembled most of the throttle and brake quadrant. This is a steerable nose wheel with a symmetrical hand brake system. I will add the brake line plumbing tomorrow and the parking valve. As is throughout the whole kit ALL M3 Rivnuts are to be upgraded to the M4 size this has required much time reaming the M3 sized holes to the larger size (and the screw holes as well). This assembly was 18 rivnuts alone and I know I am approaching over 100 holes reamed out....very time consuming.
