As promised I did measure the angle. On mine it's 70 degrees. Also in order to get a little more ground clearance I'm running a 20" front wheel in a 24" fork. And the width at the rear from fender to fender outside edge is 29". The outside edge of the tires using 20 by 1.35" rubber is 28 1/4"
Thanks for getting those measurements! But if your hubs are a standard 4" wide and your frame is 24" wide that makes the overall width 32" at least - I'm at the point where I need to cut the axle length down to it's final length . I guess the fenders are a little inside the center of the outer portion of the hub anyway right?
The Timber Wolf uses a two piece axil. The total width comes to about 32 inches. The rear weldment is 24 inches wide.
Hugh- Thanks again for the information. I don't know if it was shown in the plans, but I did not see it anywhere. I guess it's safer to have the axles as short as possible to keep the bending and chances of the wheels hitting something on the trail.
I ended up cuttting the axles down and putting a 3/16" spacer against the bearing side of each hub so it is barely more than the absolute minimum and no chance of the spokes rubbing on the frame.
I'm very happy to have your help on this and your input is most definitely appreciated!
My next question is about the disk brake- I have not welded the disk that holds the brake disk to the axle yet, and that will be the next move I think. I need to make a bracket that holds the brake caliper on to the frame, and of course the alignment of all those parts is somewhat critical if you don't want a wobble- ing brake disk that could rub or squeak when moving.
My bike shop gave me a small bracket that was for mounting a disk caliper to a leg of the front or rear fork of a regular bike, but It is probably not of much use for this application as the gap between the caliper and the rear frame is still several inches.
By the way - I probably won't get much done on the Trike for a couple of days as I'm modifying my welding cart to take an additonal gas cylinder for Argon. This is necessary if you want to do any Tig welding and I already bought the cylinder and the welder is on it's way to me in a couple of days- wish me luck!
