I'm going to set up a test bench for testing my water block designs for my university project. Showing how experimental data relates to theoretical data. The uni labs are well equiped I have access to most equipment needed and the uni will order any other items I require

. But here is where I come unstuck. I would like a way to accurately mount the water block to the die simulator but most I have seem do not seem to achieve this. I was thinking of someting along the same lines as pictured ( sorry for the dodgy pic, no CAD at home

). I was thinking I could have the heater supported on matched springs and tighten the waterblock down on top of it down to the reference block, where the loading should be correct. What do you guys think is wrong with the idea, do you think it will work in principle?
thanks for your help
