Cutting out these fittings is a matter of taking your time. I read of builders looking for pre-cut ones but honestly don't see the need as it is not difficult but just a matter of using the right cutting disk and accepting that this is 1/8" thick 4130N and isn't meant to cut like scissors do paper. Each takes about 12 minutes to cut and shape. I will wait for the final drilling in the remaining 7 fittings until they have been heated and bent into shape around the clusters. There is going to be a lot more grinding to make good fits and alignments.
