I was incorrect on the hole size too - it's 1 1/8 I believe there's a minimum of 1/8" web between holes... Getting older ****s! Mutt
The dragster looks great...! For the street I'd be less aggressive with the hole size and amount of holes. The front of that dragster doesn't take half the abuse that a heavier road car takes on the public pot holed roads!!! Mark
On my axle I used a 7/8" hole saw, the holes are on 2" centers, 17 holes. I then used the flapper wheels to knock the edges off, and give them a slight chamfer. I recommend using a drill press if you got one, set it at lowest speed like said before and use lots of oil.
You drop your own axles 29EHV8? Maybe you could give us the low down on that sometime. BTW nice holeshot in the picture of the old slingshot.

i know this thread is 10 years old but, Question, why is it nessicary to chamfer the edges? is it just looks or structral? i drilled my original dropped A axle last night with 7/8 hole saw on 3in centers (13 holes total). it was late after i drilled it and still havent deburred it. But do I NEED to chamfer the holes ?
Sharp edges in metal can lead to cracks. Chamferring or gently rounding the edges with a sanding flap wheel or hand filing are preferred methods. Good luck.
Start out first with some different size steel washers. Lay them out on the axle to experiment with different looks or spacing that you like.
