Got the chassis back blasted and took it to my mates workshop who stores my chassis jig for me (its to huge for my shop), The bugger had a half built frame on it so will have to wait

Seeing as i was somewhat stumped on the frame i decided to sort the various bits out on the front axle, The shock mount holes are tapered 3 degrees.








I turned up some tapered bungs with 1/2" holes to suit the shocks i have already.








These are pressed into the tapered holes and are really tight so don't need anything else.











There are some eared brackets cast in the axle for some sort of jacking system so were not needed, I will keep the upper ear as i may fit an anti roll bar and they are just in the right place.









Next i dealt with the kingpin size difference, The existing holes were bored out to 1" and a sleeve spun in the lathe with a 1" OD and 13/16" ID, These were then linished to be a press fit into the axle and then the holes was reamed to 0.815.












While the pillar drill was warm i decided to drill a few lightening holes in the axle, First i had to make a simple jig to hold the axle as the I beam sides are different widths so the axle won't lay flat on the table.








The jig was clamped to the table and a steel block wedge was put under the other side to keep it steady.

All had gone well with drilling the holes until i got up to the 1/2" drill, then the steel became incredibly hard and was taking the edge of the drills in seconds, after sharpening the bits several times i resorted to using carbide drills and these chewed through it much better, I don't know why it suddenly got so hard, anyone know ???

The holes were taken out to 3/4"
