Ado213 Posted May 25, 2014 Report Share Posted May 25, 2014 Here is my V2 at getting a generic crystal into a BP SD. first attempt failed WR above 3 bar. As the BP case is bored out to 30.1 mm and a generic or genuine Xtal with gasket is 29.6mm diameter, its obvious that the gen will not fit without a sleeve or ring adapter. here is my case bored to 30.1 mm inside diameter x 3.0 mm deep. you will see my "sleeve to the right of the case and below a better picture of the sleeve. Next we need a custom rehaut as in picture 3, you will see the xtal gasket to the right Ok we have this now, so lets look at the assembly, of the rehaut and gasket, picture 4. You can see that the gasket holds the Xtal by a small amount 1mm and the Xtal sits directly on top of the rehaut. Picture 5 shows the Xtal, gasket and new rehaut assembled Great. everything fits nicely and seems good so now we need to pre-assemble these components together and get ready to press them all home. Picture 6 shows the assembly prior to pressing Great nice and tight, not too tight but tight enough to give me confidence that this will be good on WR later on. Now we have pressed all components together lets look at the finished result, Picture 7 shows a top view Great looking good, I wanted the xtal that bit lower after seeing the pictures posted in this thread and that's what I got, picture 8 shows the stock BP on the right and the one Ive just machined on the left. This one passed WR at 6 bar so I am more than happy with the result. So in conclusion, it is possible to fit a gen Xtal to a BP SD. Yes you do have a 4 part assembly, rather than the genuine 3 part as shown in this thread diagram, however changing the Xtal now should be easy. Anybody wanting machining dimensions, I will post these Tuesday, cant access my works computer from here at the moment. 1 Quote Link to comment Share on other sites More sharing options...
