Dear Rich,the data that I have show about 558 l for VAS.
Greets!Interesting! Your measurements are ~100 L on average < the factory, mine, or various other's measurements I've seen posted. Did you get the predicted results in whatever alignment you chose?
That's what I got measuring a couple 515Bs with Delta mass and a CLIO.
Measured the clay with my Ohaus reloading scale, I know it's different from the factory specs but it's what I got.Did'nt build anything it was for a friend.
Dear Rich,could you post the formula you used to calculate VAS from the mass?
Thank you,
I did not calculate it from the mass...the CLIO system does a sweep,
you add a known mass to the cone run the sweep again and it spits out
the T/S parameters.You can also run the second sweep with the driver mounted in a box of known volume and it will give you the T/S numbers
based on that.
Dear Rich,I see, thank you for your reply.
