I have troubles setting the hydra with the "Bike Machinery X" and "Bike Machinery Y" values provided by BikeCad.
I am building a frame for myself, to get to know the hydra. BikeCad gives me a X value of 526 and a Y value of 276 for the head tube- bottom distance.
There seems to be a calculation step to use to be able to use these values to adjust the jig, but i do not get it.
The jig is third hand and I have no manual to refer to.
I set the head angles, bb drop, seat tube angle, chainstay length on the jig but it seems like a good idea to get the head tube on the right stop!
Any BikeCad/ hydra users willing to help?
Thank you in advance,
