Hi Jesus, and thank you for your most insightful comments surrounding the whole issue of Vacuum/Suction, and the Upsides/Downsides of Stylus Heating etc, it is greatly appreciated by this Troll. As the the Day rapidly approaches when I will be attempting to make my first recordings, I must admit that this very topic has been forefront in my mind. The 3mm O.D. Vacuum Pipe was chosen primarily, out of the simple neccessity to keep things compact for Routing Purposes. It may be the case that once I purchase and fit one of The Shank's Styli, I could find that I may be able to up the diameter a little. It is difficult to see from this Photograph but the Vacuum Pipe is actually flattened to an Oval on the Bend closest to the Stylus :- I had thought to use, and so purchased this small combination AS20W Air Brush Compressor/Vacuum Pump Unit to use on Vacuum duties :- The beauty is that it it quite quiet and is Oil Free, which is most useful as it suits my current accomodation/housing situation. I used the Flow Rate/ Velocity Calculator from this site here:- http://www.1728.org/flowrate.htm Taking the lower Flow Rate of the AS20W as 20L/Min this Calculator gives me a Velocity of 348.11Feet/Sec through a 2mm I.D. Pipe, which I'm hoping, if I only get a 1/4 of this performance, should be enough to pick up the swarf whilst I'm cutting. I am not looking to produce recordings on a Commercial Basis for Mastering, and as such I will not be Cutting Lacquers, only Polycarbonate Discs. Of course I will be trying to get the best Noise Free cuts I can acheive, so I will be aiming to use Stylus Heating. The idea is to gain as much experience as I can, Cutting in Mono, before attempting to Graduate up to Stereo with my MSS/Technics SP10/Caruso Set-Up. Now getting a Vacuum Pipe Under Caruso 128 will most definitely be more of a challenge! It's almost 2 years since I embarked on this Cutting Journey, and after over 50 years of Procrastination. I can now at last see the Finishing Line, so thanks again for the pointers Jesus.jesusfwrl wrote:It is not the type of blank you will be cutting that defines your suction needs. It is mostly a question of whether you will be using a heated stylus or not.

P.S. Jesus, I agonised over making a bid on your latest acquisition when it was offered for sale some months back (I Downloaded all the Ebay Photo's of it Te He). I even sought some advice/user tips, from mischmerz, as I know she has experience using the R.O.K. I think it's found the perfect new home to bring it back to its former glory.
