How far towards the center of a 7" should I cut?
Hi all,
I'm cutting with a vinyl recorder and someone recently mentioned to me that there are standards for how far toward the center of a 7" I should cut.
Currently if I use a groove distance of around 40 I get 4 minutes on a side, but that's only if I allow the cutterhead to slightly overlap the brass weight that gets placed over the record to hold it in place, if that makes sense?
Am I cutting too far towards the center?
Thanks!

it's worth looking at the standards, though I put a label down on a blank and find my lock groove area with that. The machine itself can cut further in than the 7" label size, but in general you don't want to get that far.

In gerneral i help(ed) myself pulling out some good sounding records, looking how the pros did it.. Measured (also the grooves depth and distance) and trie(d) to cut the same way. Of course its not possible to do a neumann high end professional cut with a vr.. but impressive results can be definitly done with it.
Average cuts: 45rpm = 4 mins 33rpm = 6 mins
Standarts are posted above, also very helpful, experience and documentation helps a lot.

When the corner of your cutting head gets bumped by the drive pin, stripping both mounting screws! I am kidding. Click the above link for aardvark mastering's RIAA stuff. That guy is really cool and knows his stuff inside and out and has made some crazy innovations. Yep
