Thread: Making a frame from scratch??????

Tweet

Nice looking rear frame, the bags and everything else look like they are very nicely gusseted.

AHH ,good ol firestone double convoluted bags,I have em on my ride too!!That little gusset on top of the bag mount makes a world of difference in strenth.Nice work!!!

I hope you will allow me to offer some critism of the rear suspension for the Murray without getting upset with me.
I know you said it has worked for you in the past but I can't help but wonder just how WELL it worked...
I am a suspension designer by trade and all I see in your execution is a set of door hinges attached to the axle... The solid clamping at the axle and tightly constrained bushings up front will allow for no axle tramp or "roll" (i.e. left wheel down, right wheel up) without the bending and twisting of the front frame brackets. I HAVE to tell you to re-think this design with the addition of bushings at the axle attachments and at least a third "upper" bar to control the then present axle rotation. This will allow the axle to roll a bit as the car goes around corners and into driveways without over stressing the frame attachments. As it is, the only rotation the axle can do "freely", is up and down, like a door on straight hinges. It HAS to be able to rotate around the front and rear bushings also to operate properly and provide a decent ride without "skipping" around corners.
As was mentioned earlier the front panhard mount needs to be put into double shear also with the rotation direction of the bushing rotated 90*'s to put it into compliance with the rear axle motion. The design as it is is putting a pure bending moment on that single shear bolt and it will break over time...
I am concerned for your customers safety and his passengers and fellow drivers as well.
After some more study I would recommend putting the forward panhard bar attachment on the frame. Not the trailing link...
