With a frame up on sawhorses, what measurements will tell if it is straight, or crooked?
I plan on seeing a couple, maybe more, forum members with frames for sale on my trip to Baltimore and back.
I simply have no way to straighten a frame, nor have I ever seen it done, so I very much want to buy a straight one.
Any help is appreciated.
If the frame looks strait ,that's a good start . Put your frame on your sawhorses and measure from the front corner to the opposite back corner . note measurement . then do the same thing on the other corners . When the measurements are the same the frame is square . You can get bows out of the rails with a peace of I beam and some large C clamps and wood blocks .
Thank you, Perry.
Bill, might I suggest you use heat to shrink a frame that is bent in lieu of using another bend to straighten it. Also, it is best to use a pencil-tip torch to heat the rivets, and then re-buck them tight again with a 3X Rivet Gun.
all frame measurements and squareness checks can be made using dimensions found on FUN PROJECTS website under (if I remember correctly) "technical info"
Thank you, Scott.
