Hi Ralph...

the clamping idea sounds great   altho i did mine all "free-hand" on a
drill press with good results ...  but the clamping idea should
definately increase the accuracy...   just be sure that when you off-set
the plates it is measured well or else you will have the tubes too far
over on one side...

for example...

if you are using 1" tubes with a 1/2" seperation   shift the plates by
3/4" when you reclamp them to drill the screw mount holes for the tubes
