S & V no longer stock road springs. For my J2/J4 replica, they have recommended I contact Jones Springs, their previous suppliers. My question is was the same springs supplied for each model, or did perhaps the J3 / J4 have a stronger temper ? Much appreciated.

The J4 had rear spring unique to the J4 and C types. Front springs were common to J4, C type, PA and PB and TA.
The J3 had the same rear spring as the J2 but there was an extra leaf in the front spring on a J3 to that of the J2.
There is a section on Spring Data in "Blower", if you have a copy, showing all data and dimensions.

Chris. When you get a copy of "Blower" bear in mind that Brost Forge in North London also do road springs. I have also come across a master blacksmith (a member of the Guild of Blacksmith's) who does a lot of springs for horse-drawn carts. I would have thought that he could manage a set of road springs for a J if he is provided with a set of drawings (contained in "Blower") and he is close enough to call in to discuss the project. He is based at Ashurst Wood near East Grinstead. I have no personal experience of him yet, but when I next need road springs I intend to talk to him.

PS They will also supply with an oversize 'eye' (5/8") if asked to allow for the insertion of a 1/16" bronze bush. |

Excellent, Thankyou Robin, Colin & John. I will contact Brost Forge on Monday, and for the information on the spring types for each model. I can now move forward.

Slightly off the subject... did any one else see the TV prog. may have been "Grand Designs" when the old Brost Forge premises was developed....,,just glad the business survived.

By the way Chris, the spring makers will tell you that they can only supply metric thicknesses these days. I know of some people who have the metric thicknesses reduced on a surface grinder before tempering to the correct thicknesses originally specified. Added cost, I know but if a job is worth doing, it is worth doing properly.

Chris,
You can check with Chris Wann, but he still uses Imperial. He can't however get 7/32 inch because it is no longer available.
Regards, JOHN |
