So I just bought a brand new Raytech 10" saw w auto feed and I have been cutting using the auto feed only for a couple days and sometimes the slabs are perfect! and sometimes there not ... Any ideas? The saw did come beat up in the box ... the cheap board on the bottom was split up and a screw holding the belt cover bent a lil " it probably took a small bang here and there but I have spoken with them about that so they are aware of it . but that was just some cheap hard cardboard like board ...maybe its something Iam doing ?

are you re-adjusting the stone in the vise after every couple slabs or so to expose more material? could be you're not replacing the stone's cut face perfectly vertical and horizontal to the blade resulting in a skewed cut.

no This is just between crossfeed adjustments only

there is something weird about the crossfeed and that is it wont turn unless the wooden board and the clamp is about 1/4" away from the metal tray ... i might need to video that one ... that seems very weird and off to me ..Iam wondering if the nut that is welded on is slightly off..or like i said is this semi normal ...even for a new saw ..

Sounds like you may not be clamping the rock tight enough in the vise. You may have to use wooden shims to get the rock clamped tightly. After clamping a rock, grab it with your hand and try to move it in the vise. If it moves, loosen it up and shim it. A loose stone can dish or damage your blade. Don

yeah i just cut a really long one and when i grabbed it before i cut it it was fineand i couldnt move it but when it was done i grabbed it again and it moved ... that one was pretty uneven .. also it seems the longer slabs are uneven and the shorter ones are even .

The vise on my saw has a nut on the side of the vice base which you need to loosen to move the crossfeed and tighten before you begin the cut. Otherwise it will not hold the parallel position you want for even slabs. Other problems can be as stated, the rock shifting because it's not tight in the vice or your blade might be dished so it doesn't travel correctly in the cut every time. Also, the blade may be hitting a lump. slanted area or other irregularity on the stone to blade contact area which makes the blade slip to one direction o the other so it does not enter the cut perpendicular to the stone. This will usually stop a big blade but on smaller saws, sometimes they will go ahead and bull their way through the cut. This offsetting of the blade will eventually ruin the blade though.....Mel

blade seems pretty true ... it wobbles some when its starting up and slowing down to a stop but when its running it seems very true and straight .It was like that on day one .. .. I had time to make one shim (handsaw) and I must say it really made a difference with the stability ... I ran out of time for cutting so hopefully tomorrow the shims will fix the problem and I will be cutting some long even slabs .. and yes mine has that nut but its on the front side ..

i don't think the blade should wobble on startup.
you will have to make sure the rock is tight.
also, look for the lock Mel wrote about. Both my Lortone saws have a cross-feed lock.
if it moves too much, it will soon bend the blade.

well ive spent from morning till night 2 days in a row and it can cut straight slabs .... to a point which is about somewhat past half way through the saw blade (about a 5 inch slab or so )... so when a cut is done without removing the rock i push the carriage foward after the cut is done and the rocks edge will push up against the blade after the halfway mark on the sawblade and push the blade to the left slightly ... so if this happens when its running I imagine the blade can get5 warped after awhile ..so i tried to realign and move the carriage over following the directions ... it seems better but not perfect ... the blade definately does wobble a little too ... so iam guessing its the blade or the saw itself is misaligned or both ... not a good day ...will give them a call tomorrow ..

G'day Greg I'm glad that you have got yourself a saw and are turning out a few slabs, like most things a lot of trial and error help give you experience and i'm sure that with practice you will get it down pat. I also have a 10" and sometimes I go good sometimes not so good at the moment I need a new blade. Bill
