11. This illustrates two things, first there are several complex angles in the side framerails, and second it takes a lot of clamps to hold a framerail together for welding.
12. Even though the pieces are clamped in, the fixture measurements are constantly checked prior to welding. Here the distance from the second body mount hole to the front frame end is checked. One of the tricky spots on the chassis is the transition from the main framerail to the rear kick up. Once again alignment tabs inside the box tubing align the pieces.
13. A transition piece is formed from a piece of the box tubing to blend the framerails together, here the vertical weld has been completed in the proper uphill welding pattern. This will all be ground smooth.
14. The rear crossmember and framerail corner is a complex corner with a lot of machined pieces. This is to provide mounts and access for the stock '51 Ford bumpers.
15. The corner plates were first tacked in place, and then finished welded to the rear crossmember and side 'rail. This is a fine example of what a structural weld should look like.
16. The front crossmember is tack-welded in place with 3 degrees of antidive built into the placement, which is all part of proper alignment.
17. Moving to the center of the chassis X-member construction begins by installing the two upper legs of the X-member. Once again the fixture locates the pieces precisely.
18. The center pieces that connect the two outer legs of the upper X-member incorporate a driveshaft loop that will clear the stock '51 Ford floor tunnel.
19. The rear crossmember is then located and tack-welded in place. Once again the center line string serves as a reference to ensure all the crossmembers are in proper alignment.
20. The final crossmember is the coilover shock mount crossmember that rests atop the fear frame kick-up sections.
21. Once again a few giant C-clamps mate the upper and lower portions of the center X-member.
22. With all eight of the lower X-member pieces tacked in place it's clear that this is one very rigid platform for the shoebox Ford.
23. The chassis rotisserie makes short work of the finish welding. Alternating sides of the chassis prevent distortion from welding.
24. The front crossmember is finish welded, adjoining the recess formed for the spring pocket and the C-notch for the rack-and-pinion. After welding up the entire chassis Eric Kisiah turns his attention to mounting the suspension brackets. Our chassis is using QA1 coilover shocks on all four corners so coilover brackets are installed.
25. Note how the coilover upper bracket piece interlocks prior to welding. This makes for one very strong mount. Fatman Fabrications also offers conventional coil spring pockets.
26. The front coilover brackets are finish welded, alternating from side to side of the chassis to prevent any chance of chassis distortion.
27. Moving to the rear it's time to attach the forward brackets for the rear four-link suspension that will locate the 9-inch rear. The QA1 shocks mount behind the housing of the rear crossmember.
28. There were just a few more body mount holes to drill so the magnetic drill press was put to good use once again. Having the body mount holes drilled takes the mystery out of fitting your Ford to the frame.
29. This side view shows the "outrigger" body mounts in place on the outside of the framerails; this is a true bolt-in chassis.
