Hi, there are various ways to overcome the problem of the axle lining up with the mounting screw holes with the MJK Dog Bone chassis. One is bending the screw mount tabs over 180 degrees & notching the chassis to clear. The other is to angle the screw tabs so the wall plug misses the axle. This means that the wall plug may be at up to 45 degrees to the body contact point. Both these methods work but I decided a different approach. In this case the chassis was too long for the project body anyway.

This method I used a car body tool used in rust repair. The rust is cut out and the remaining metal is stamped in a "Z" with this air tool to form a recess so the new metal plate is flush with the original panel ready for welding in place.

I put the chassis as original in a plywood and angle plastic jig. The plastic angle was drilled for the axles at the desired wheel base ans also at the correct height for the chassis resting on the plywood base. after squaring up the plastic angles were screwed to the base with the chassis in place and the angle pieces fitted on the axles

I marked the chassis at the cut on the point. I then marked at 11mm from the cut on the chassis piece I wanted to end on top at the "Z' join. I did these wit a small square so they are right angles to the center strip of the dog bone chassis.

The chassis was then cut with a normal hacksaw with medium teeth. The piece to be on top at the join was then pressed to the "Z" shape by the Air tool. That piece was then drilled for 1/8" rivets. Best to take the hole jig & chassis to a drill press to drill. I then rotary filed the holes slightly so the pop rivets fitted in snugly. A snug fit is important to make sure the chassis can't move out of line.

The chassis is then fitted back into the jig with the axles inserted in the correct adjustment hole for the wheel base and the fit of the "Z" joint. I did not do this but I now suggest fitting 2 screws into the ply wood each side of each piece near the join. This should hold the chassis halves in alignment while drilling.

I would suggest doing one rivet hole first and fitting the rivet after removing the chassis pieces from the jig . Then replace the chassis in the jig and drill though the second rivet hole. Fit the second rivet then dress the rivet head with a file but don't take too much off- clearance should be OK . If not bend the chassis center slightly

Next - assemble the chassis & body & have fun - John

PS most crash repairers would have the air tool to do the "Z" hopefully they would do it for goodwill. If not contact me & I will do it for you.
