I'm building another recumbent trike, my fifth.
I'm using the same components from a two wheeler I made that I can't ride due to balance issues. It will feature:
Ackerman and centrepoint steering
Adjustable toe in
Shimano Deore cycle parts
Tektro hydaulic disks
700c rear wheel
20" front wheels.
Wheelbase 115cm
Track 760mm
Seat height 240m
Bottom bracket height 400mm
Frame 30mm tube
Kingpin angle 15 degrees
Wheel angle 5 degrees
27 speed
9 speed cassete
3 speed chainring
To date I've built the frame, welded up the stub axles, added caliper mounts and ackerman angled steering levers, added a bottom bracket and front deraileur mount, turned up some Delrin chain idlers and fixed the rear derailleur mount and sorted the hubs and quick release levers. Today I welded up some seat bracketing and bent and twisted some 3mm ally sheeting for the seat and back. Pulled it down off the bench and sat in it to try, very impressed - very, very comfortable.
Rims should arrive late next week, soon as they get here I'll measure up for spokes and order them then stick the wheels together. Once done I can start on the steering and associated linkages, then go for a trial run, sort out any problems and paint.
Here some pictures, frame all welded up, stubs welded up, calipers mounted, front derailleur and BB installed.
