    Crowns can run either way and are buggers for following grain, as are PGT's.
    Seems speed was the problem and slow speeds are not a good idea, try about half way then vary to suit yourself.
    Beginners are inclined to be a little afraid of speed but ultimately you will find that high speed gives better rresults once you get over the grab and bang (real character building stuff isn't it?), just takes a little while but you will get there.
    Also look at reverse tooth blades, the bottom inch or so is reversed to minimise tearout.
    No need for spray or wax and blunt blades will burn the wood without any additionial assistance, some harder woods will just burn anyway and there is little that you can do about it apart from a light sand when finished.

    Had another play around last night....

    Cut out a name from some 1/4" plywood....I did ok, but obviously need practice moving the workpiece to stay on the lines! Went a bit out of control here and there!

    Was no burning with the crown tooth...very nice finish actually...and no chipout either!! and I experimented with changing saw speeds...Still get that high pitched screech cutting sound...like when you hand saw wood, but higher pitched...so its probably just the wood scraping on the blade...

    I used spray adhesive to fix the pattern...stuck it down really well and I thought I would have a hard job removing it afterwards, but i just picked up a corner and it peeled off beautifully!

    So at least i have that part licked
    How much wood could the woodchuck chuck if the woodchuck could chuck wood?
