how do you set VTA onthe SME 309 tonearm?

You guys are making this way too complicated...

Not sure where audio779 disappeared to, but if he purchased the tonearm new then he already has the proper hex wrench tool. It's the one with the handle like a screwdriver. If he doesn't have the SME tool then a simple 3mm Allen/hex wrench will work. No center drilling required.

Only advantage to the SME tool is that it has rounded corners for convenience in fitting (and turning) the wrench in the bolt heads. SME (UK) or Acoustic Sounds (USA) or Flat Earth Audio (USA) would be glad to sell him a replacement.

To add to Tom's comments above, the OP never asked about a tool. He asked how to set the VTA of the arm. I bet he already has the wrench. He justed needed to know how to raise and lower the arm post.

Tom even showed him where the screws were in the link he provided, so yeah, this got way over complicated...

But isn't it more fun to visit a machine shop and DIY a wrench you already own? ;-)

Yes, but if you look at the pics carefully, you'll see that they use tamper proof bolts on the vta adjustment. If you don't loosen them there's no way to set vta. You need special sockets. They sell them in Lowes, and they're not expensive.

Those really aren't meant to be "tamper proof" screws. They are just what SME uses and the tool is included with all the arms. It's not rocket science.
