maTILTa
Posted by Craig Hendrickson On 2013/7/8 12:56:19
The front maTILTa has been completed.
maTILTas are bolted to the brake drum using grade 8 hardware (only the top bolt installed in the trial fit shown) with a 3in clearance hole for the hub so the backing plate is flush with the outside of the drum when bolted down.
The purpose of the maTILTas is to allow one side (in this case the driver side) of the 55 Clipper Super 4dr to be lifted with a cherry picker (engine hoist) to rotate the car from a horizontal to a vertical position. Once vertical, ALL the force is taken through the center of the hubs through new, custom fitted wood blocks (not shown in these pictures), down to the ground. At that point, the maTILTas are not supporting any significant weight. Over vertical rotation is prevented by the "tilt stop" legs (the tall vertical 2x4s shown in the pictures).
In addition, the "B" pillar will be supported too with small "A" frame and some wood. I haven't built this yet, but I'll show it later when done.
Also not shown, but after the tilt, both the front and rear of the Clipper will be triangulated with 2x4 A-frames, so that it would take a tornado to push it out of it's vertical position. There are no tornados in Pahrump, NV.
Here's a series of views of the completed front maTILTa:
Here's the empty front load box. During actual tilt, there will be a custom tight fit new piece of wood inserted between the hub stud (dust cap removed) and the bottom of the load bar. Therefore, when the car is tilted, ALL all of the force of the weight of front end will be transmitted through the suspension to the load box to the ground. The maTILTas support very little weight at that point.
There's another part of maTILTa not shown or installed in these pictures which is the "anti-rotate" bar which is across the top and binds against one of the front fender brackets. It's purpose is to prevent any possible rotation of the brake drum.
I have many more pictures of the construction, if you are interested. The actual lift/tilt awaits some more construction.
