    You know how they install those valve seats? I have done mechanic work almost all my adult life and I have come across some puzzlers
    but never saw that one! It must have been making a god awful noise.

    LOL just saw this.....As I understand it the steel seats are pressed into the aluminum casting...not really sure exactly how that is done...carefully I suppose ;) I am loving the way the engine runs with all new upper parts. The actual cylinder where the seat had dislodged was a little noisy clacking but not really loud.

    It is a shrink fit when they are steel to steel, not sure about the steel to aluminum. The seat and that area in the head are ground to a very tight tolerances. The head just a bith larger than the seat. The head is heated up, the seat is frozen, then they drop it in, the head contracts, the seat expands, voila. One way to do it.

    We also use shrink fits on high speed machining. Cutting at high spindle rpm and feed rate, the end mills tend to pull out of the holders. Your standard holder has either a collet or a large set screw or two to hold the end mill. With the shrink fit holders, it works the same way. You go to fast you break the mill no matter what.

    TAE, thanks for reply.

    I used Pro Tools in past and trying to avoid DAW (and spending money on faster laptop and software).

    Are you familiar with any synth workstation (under $2K) which are able to record guitar and vox into sequencer (via line in) and incorporate them into final stereo mix?
