To be honest on the one peek that I did (ok as I said I wasn't experienced ) and broke when they brought it back to the lab I noticed small pieces of composite missing like they chipped of and I've seen other small cracks as if the composite was gonna chip more. I thought that that was because the peek flexes and it cracks the composite what do, you think? I also had the concavity issue on the tissue side [emoji3]
Not sure about the PEEK...but the Pekkton didn't do that at all. If you really want to get more hands-on experience with high performance polymers get with Lee Mullins and Phil Reddington, they are wizards at this stuff. I know Lee does a one-on-one course (which you never see anymore),but they are all over the world doing day and weekend lectures depending where you live. The BDT technique is one of the techniques they invented using these high performance polymers. Bill Marais is the guru here in the United States and he does a lot of stateside courses. Danny Roberts (also member here) is probably the guru I'd trust for anything metal hybrid or any bar for that matter. John Wilson (was a member here) is the go to guy for Zirconia hybrids here in the states as well. Bob Hicks is the smartest cookie I know when it comes to putting attachments and bars together, in the states also. I know Dimitris (a member here) does quite a bit of various type of hybrids as well (he's in europe). Those are the list off my head that I'd pick their brain when it comes to this type of work. Keep at it, it's a learning process for sure, but I would seriously look into some of these courses/lectures if you want to become very proficient at it. Hope that helps.
Refocused to facebook.
Sounds like the 2000th iteration of that topic.
He was banned because he was always combative with the other members here.
