The raw material once again provided by the guys at Tri-Angle Metal Fab. When the rear pinion bearing in the front diff seized and stopped the 109 hard, it wound up the right front suspension (pretty much like the abuse most people put their old Series trucks through off road) and caused the front drive shaft to contact the relocated oil pan breather pipe. I have plenty of clearance, but under extreme circumstances, the two may meet again. So, after a conversation with Mark and Arthur at RN we decided that extending the shackles would get the “extreme event” clearance I need, I wouldn’t have to re-work the oil pan (again), and it will pitch the Salisbury back a bit (more oil to the back bearings, thank you very much). And for the tech-heads out there, yes, the caster angle will change, but only a few degrees, and in the tighter, not sloppier steering direction. So off to the Bridgeport………..
The blanks and the stock shackles
Start drilling…..the magnetic indicator holder allows you to place each identical blank in the same place every time……….this saves a ton of time in set up and edge finding, you only have to do your set up once this way
Another gigantic time saver, and a guarantee of accuracy……the digital readout (DRO).
The math to plug into the DRO…….assured perfection
Another nice trick on the Bridgeport……drill the holes, then put the spindle in neutral, insert the tap, rotate by hand, the hole gets tapped perfectly straight
Best stuff on earth for tapping…….like butta
Drilled and tapped, fronts and rears
Spacers for the front shackles were cut from solid bar, bored on the Bridgeport, then tig welded to the shackles
Cleaned up and ready for coating
Coated with POR15……..rock hard finish, goes on quickly and self levels, and when you get it on your hands it stays there for weeks!
