Maybe I’m missing something, but don’t
you have to drill the leg positioned in the mount? If so, how can you use a
drill press?

Bryan, if you decided to drill your legs,
in addition to a drill press, the drill bit itself is important. I would
not attempt it unless I used a quality colbalt drill bit (not carbide
- too brittle). I would start off with a drill bit undersize but not
smaller than 1/8" perhaps 3/16" (too small and they may
wander). Then if you progressively enlarge the hold with a larger drill
bit, you are more likely to drill a straight hole. You will need to drill
at a slow rpm or risk burning the drill bit and hardening the metal even more.
If you do not feel comfortable doing this, then the shipping
charges to someone who knows what they are doing is probably cheap in the long
run.
I drilled my own (successfully), but, only because I could not
find anyone at the time to do it for me{:>)

That’s what I wanted to do, but Ed K
prefers to mount the clips undrilled. This forces me to drill the
legs. But, he is apparently able to use Van’s mount. Did he
charge more for this approach as opposed to his preferred way? I guess
shipping is more costly.
I guess I need to run it by him again.
I haven’t bought any mount, but I really don’t want to drill
my legs.

The gear legs were straight from Vans. After having been ripped
off by Fred Breeze (Conversion Concepts) I ordered an engine mount and matching
gear legs from Vans and had Ed Klepis convert it. I had bought a pair from
Harman Lang several years ago to be match drill to the CC mount, but after
spending the money and not getting the mount I sold them to someone in Texas can't now
remember. The only advice that I can relay is that of a machinist friend.
Use a good sharp centering punch and good luck if you don't have a good
drill press to mount the gear leg in.

as you can see in the photo I used a laser light level to
find the distance, but as you probably know the line gets somewhat thick the
father you get from the source. SO you can add or subtract a 16 th.
I got 4" 15/16. Ed Klepis probably has that figure in his
notebook. Let me know what other numbers you come up with.
