Title: fork brace
Post by: jimson on June 06, 2013, 02:32:18 pm

G,day viewers I need to make a fork brace for my Hannibal project. What's the best way to do this I was thinking of making it out of plate steel  as I need it to be a brake stay as well. So do I heat the metal before I bend it ? Jimson

I have,nt bought it yet. I will have to measure it I,m just a little worried about making the metal weak by bending it cold. For strength should I heat it before I bend it ? How thick should I go ?   Jimson

Mate, I reckon most fork braces are aluminium, but i reckon you could make it out of Approx 5 x 80mm mild steel bar (Black bar) or rolled hot steel. You could heat it to make it easier...

Aluminum is the go Jimson, if only to stop having another tonne of weight ;)

G,day Tim I need to put a lug on the bottom to catch the brake hub. This means welding so steel is something I can do in the  shed. If I use aluminum I have to pay somone. Jimson

Fair call! Will have a search for some pictures of after market braces in a few magazines for you.
