Are Bradford springs the same as Jowett 7 springs?

Are Bradford springs the same as Jowett 7 springs?
The 7 is approx 1931-33.

Dad and I compaired the front springs of the Bradford ones and the 7s they look like they will work.
But we dont have any rear Braddy springs to compair at the moment.
My 7 springs are pretty pitted and rusted up, so trying to find a good replacement.

Thanks

Front spring leaf bolt is central on Bradford and pre-war, but Bradford rear spring leaf bolt is'nt central, although pre-war is.

Tony.

Could It be possible to redrill a Bradford one to a cenral position? Or would doing this weaken the spring too much?

Thanks

Hello again ‘Bradford man’.

I don’t know what adding an extra hole to a set of spring leaves does regarding Health and Safety, or even to a spring leaf failure on a dark country road after midnight when it’s pouring down and you’re in the ditch, and your mobile’s battery has just died.

When I made up the rear springs for my 1933 ‘Flying Fox’ I used the original top leaves from such a pre-war car, but added some of the other leaves from the Bradford rear springs I obtained from Jowett Car Spares Ltd..

Using an angle-grinder, I chopped off a short length of the longer part of each of the Bradford leaves so that the hole was in the middle of the resulting spring leaf.

When fitted together the result was a rather stiffer, but similar couple of springs to the real pre-war ones.

I presume you’ve dismantled the springs, but if not, and as a warning to others who might want to do so, when you’ve slightly loosened the bolt holding the leaves together, splay them out so they look like a chrysanthemum flower. This relieves much of the inherent springing forces, because if you just remove the central bolt, the leaves may just decapitate you as they burst apart, before destroying the garage, (or if you’re in OZ, The Shed)

If your top pre-war spring leaves are past their sell by date, and you have a decent pair of rear Bradford springs, then re-manufacture of the top pre-war leaves only, coupled with fettled Bradford spring leaves should sort you out at much lesser cost than remanufacture of a complete spring set.

Hope this helps,

Tony.

Well today I pulled some reasonal Rear Springs off a Bradford rear axle.
That I had planned to use to modify to work on the 7.
I had all the springs laid out on the table.
Interesting thing I noticed that both front and rear Bradford springs were in central positions.
The 7 springs were the almost identical exept for having a extra leaf and leafs being thinner







Also can some one tell me if the longest spring in the pic is a Jowett spring?
I thought it came off my 1935 chassie but when compairing it on it, its a tad big to work.
Its about 40 inch between the eyes


Thanks
