Has ANY ONE on here tried to drill vertically thru a MOPAR wavy axle ? I believe its a 1936 Plymouth or Dodge .......
I’ll go out on a limb, first I don’t know how Mopar constructed those axles but I assume they have forged ends. Secondly, we don’t know your plan for modifying the axle. Since you mention drilling vertically it sounds like you may want to add spring perches as on an early Ford axle. If that’s correct I think the best way is on a mill where you can set it up to be rigid and with accuracy from side to side. A moderately sized radial drill press would work too, but either way is going to be with machine shop equipment, not home shop machines. And if it is perches you want you will also need to add 60* angle seats for the perches and nuts. Those could either be salvaged from an old wishbone and trimmed up to suit or made new from bar stock.
Are you attempting to drill through the axle to put (looking for a term here) the pieces to run Ford spring perches through? Years ago when tube axles were becoming the hot lick someone was selling axle parts incuding the ends for the king pins and the sleeves(??) for the Ford perches. I'm thinking that was in the screw it up yourself and save money 70's though. As far as the Wavy axle, I am pretty sure that the center is tube with forged ends welded to it.
No, the ones I have are bent tube with the ends fishmouthed and formed around the kingpin bung. A simple weld holds it together there. (The Mopar is the shiny axle, not to be confused with a Superbell in front of it) I haven’t done it, but I’ve seen Mopar tube axles that have been drilled and a bung welded in to take a Ford-style wishbone. I imagine it would be the same operation as building a brand new tube axle. Like Speedway probably makes a hundred every day for their T-bucket kits. Drill the hole, whittle up the appropriate size perch bungs, then weld them in.
