Probably should buy a 'protractor' to set-up stylus and cartridge, so where is the best place to buy one?

Hello Peter, welcome to this forum. It all depends on how accurate you need it to be or how much you are prepared to pay (from free up to £££s).
A good place to start is to print your own & I recommend Conrad Hoffmans' arc protractor (it's a free programme). Arc protractors have the benefit that they set all the critical factors at once - alignment, overhang and offset angle.
You need to know the measurement from the centre of the pivot point on the arm to the centre of the spindle which holds the record (if you can't find this, I or someone on here can probably help you if you provide the name of your turntable/arm). Input this measurement into the blank cell as in the image below and for starters, choose IEC and Lofgren A (or Stevenson A if you listen to a lot of classical music or LPs with narrow run-out grooves). The most important thing is to ensure it prints exactly to scale so you may need to adjust the correction factors X-Y and print a few times. To cut out the centre hole you can use a pin and make lots of close spaced tiny holes so it pushes out along the perforated line.  If this all seems too complicated then another good place to start is to buy the HiFi News test LP - it helps set up the turntable and has a series of printed 2 point protractors. I don't find this as accurate as an arc protractor but it is easier to use. There are also various other print-yourself free protractors available on the Vinyl Engine forum or others to buy on ebay Good luck & feel free to ask for help with whatever you choose.

I'm tempted to have a stab at using the arc protractor myself. If you can tell me the pivot to spindle distance of my ProJect 1Xpression Carbon UKX table (it has a an 8.6CC Evolution carbon tonearm that has an effective arm length of 218.5mm) it'll save me getting my ruler out :)

PaulH, hopefully forum member Drewan77 can answer your question regarding 'cartridge set-up' as I too am a novice and have not yet set-up my cartridge using an arc protractor.
I still need to find out the distance between my spindle and tone arm pivot point. I have looked at several videos on YouTube regarding cartridge set-up but would like to find some literature on the subject to read and refer to. I'm all for the learning process and you could say 'I'm on the steep part of my learning curve.' Good luck and as I said ask Drewan77. |

Paul: I had a look at the specs Henley publish and the 8.6CC Evolution carbon tonearm has a pivot-spindle measurement of 200mm (218.5mm - 18.5mm overhang)

Thank you. Very good of you to take the time to look it up. If I'd known the calculation was that straightforward (effective length minus overhang) I'd have worked it out for myself :)

Drewan77, after emailing Fatmangolf regarding a loaner phono amp he told me my Technics 1200 had a spindle to pivot point of 215mm, but I am after numbers for the point or points to use with the Hi-Fi News Test LP protractor.
