Down the road I’m going to build a 28 model A woodie. I want to keep the floor flat so using a model A transverse spring is out of the question and I have a brookville boxed chassis already. I have a car with coil overs and it rides nice but it would be kool to do something different. If anyone has used these and have pictures I would appreciate it.
Rite on! So will you run a pan hard bar? I have quarter elliptical on the front of my T modified without a bar.
A perfectly good idea. I've even seen modified stock car oval racers that used them back in the 1960s. Your other space saving option would be torsion bars.
I've done several. PM me with your e-mail for a few pictures of my version. Made my first 1/4 elliptic chassis in 1984 under the rear of Henry bodied deuce highboy, the car is still going with close to 200K on the clock. My last was a couple years ago under Dale Grau's Green Hornet 32 lakester.
I was going to run these on the back of my 40, but decided that I needed to try and get it done, so stuck to the transverse spring . Would have been nice.
Yep. I pulled the body up so you can see it better. quarter elliptical springs, ladder bars and Panhard bar. very comfortable riding car.
@Primered Forever model A has 1/4 springs in the back. Mine will as well but right now it’s a pile of parts
The above picture is how I did my first 1/4 elliptic rear in 1984 only I put the spring on top and the bar on the bottom. It was a deuce highboy roadster that is still on the road up in WA and has around 200K on the clock.
Short springs (which all 1/4 elip are) are stiff and hard to tune as any little addition or removal of a thin leaf will have a big impact. I would utilize a fairly flat spring and copy a model AA truck though obviously with a spring more suitable for a car. The spring can go under the frame rather than beside it and it would probably be most convenient to make it the lower link for the axle rather than the upper. As a bonus you can tune the ride height with the shackle.
