Has anyone ever tried using a thin pro slicer blade on a 10" saw with a power feed ? and the results ... The reason I ask is that the blades show to be recommended at 3400 rpmsbut my 10" spins at about 1750-2000 .. the smaller 6" trim saws spin about 3500 rpms ... but then why do they make em  ?at 10" Something tells if i cut small rocks there wont be any problems ... what do you think or have had experience with ? |

I use the Pro Slicer blades exclusively on my 10" Lortone , but I only use it as a trim or mini slab saw. It doesn't have a power feed. I'll look at the pulley setup tomorrow and see what speed i'm running it at.

Hi Greg, I am probably the last person to be posting to this thread but wouldn't a pulley ratio of 2 to 1 solve that issue? 1750 RPM X 2=3500 :2cents: Stu |

yeah stu .. I have thought of that as well .. which means i would have to find a smaller pulley than the one on there right now on the motor and the same width as the belt ... the thing is that the pulley is pretty small as it is ... and theres no room for making the one on the saw any bigger .... its a possability though i will look into .. Thanks Bobby !

Yeah, I only used one once for slab trimming. Eloxite said not to use it for slabbing. It trimmed slabs like butter. Worked really well for that use but it wore out fairly fast.....Mel

Pro Slicer is a thin plated blade used mostly for hand trimming expensive rough. The higher speed recommended helps keep the blade rigid. With a power feed you will likely not have much luck slabbing as blade would have too much flex. As all plated blades the diamond is strictly on the surface so they won't last as long as sintered blades. I don't remember if it was this year or last, but Indian Jeweler Supply was marketing a copy they made for less. Johnson Bros. was not happy.

maybe ill just hold off until i get a trim saw with vice and then put one on it ... thats the expensive route though ... i was just gunna get a slab grabber and the blade and throw it on the 10" ... Iam still undecided ... but when i try trimming with my 10" saw my blade on there now has too much flex but when i use the power feed it does just fine ... Iam still tempted to try and save like 3 to 400$ and when it doesnt work you guys can all say i told you so ...lol and ill sell it on ebay for 1/2 what i paid .. still waiting on bobby1 !!!! i will only try and slab small rocks !.25 lb to .5 lb

Some savings, Greg. Why don't you spend $110 for an MK145 4" tile saw with 303C blade? It is an amazing trim saw for the money. Or, buy a cheapie 4" tile saw with 5/8" arbor and put a 303C blade on it. Leave the 10" for slabbing or trimming rocks 1" and over.

well i have a 7" qep ... the thing is Iam starting to accumulate alot of very expensive rough but all small stuff ... or just some amazing rough i dont wanna waste ...also looking now at that mk145 ... is the blade 4and1/2? if so would i lose if i buy a 4" 303c?... that might take the 1 " thick cut even smaller ... or i could use my qep with a 6" trim saw but tehn i have no vice for slabbing ... well thanks for all the suggestions ... time to get ready for work and start saving ..lol

I made a mistake. Mine is an 8" saw. I have a 2-1/2" Pulley on the motor and 1-3/4" on the saw shaft. 1725 motor. Blade shaft speed is 2464. I realize that the blade is plated vs sintered but I really like the speed that it cuts and I get reasonable life for my use.

Greg, you won't really slab with a 4" or 6" trim saw. The vise on a 6" saw is mostly used by facetors to square cut preforms. Most 6" lapidary saws have a 1 1/3" to at most 1 1/2". You could slab really small The MK145 comes with a 4.5" tile blade and a 4" 303C lapidary blade (.020"). Cutting height is about 7/8" with the 4" blade. The trim saw is really used for trimming slabs. On your pulley question, if the pulleys are same size, doubling the motor pulley would indeed double the speed. As far as selling the Proslicer for 1/2, I'm guessing it would be in the trash after using it.

I agree with John. Use the ProSlicer for trimming and get a 303 for slabbing on the 10". There's not a lot of diamond on a ProSlicer, at least compared to a 303.

I use it as a trim saw blade too, and to cut expensive small rough
I do not feel it would be a good all around cutting blade because of the thiness.

i have to also vote for the 303 blade , i ran one on my 6inch trim saw and it was great , long lasting and smooth cutting .. i mounted a 8 inch pro on my customized workforce and bent the hella out of it , now its junk hang'n on the wall as a reminder lol noooooo thin blades

And Greg, if your 10" .040" blade deflects when hand feeding you are pushing way too hard.

Stu, I answered your PM about this but short version is the MK170 has same major problem as the Workforce. It is a 7" saw so only thick tile/granite blades available. With 5500 rpm it is way over recommended blade speeds for 6" thinner blades. The MK145 4" also runs 5500 (with 1/2 hp motor) but that is the top rated speed for 4" 303C. As far as the other saws the Ameritool 4" (can use a 5" also) and the High Tech saws are very good.

just ta lett you all know ... i decided to hold way off on that pro blade ... i did buy a new 5" slabgrabber for 20$ t play with though ... thanks ... and stu i wish i could help but i only have experience with the cheap o trim saw from qep home depot ... but if i could do it over i might getthe 4 " trim saw !if i knew i was getting a bigger slab saw as well ... but if it was only one id stick with the 7" trim saw cheapy so i could roll my big rock rough on it ... like i did for a couple years ...

Stu, The Rock rascal model j and the 4th one on your list are good trim saws, I would avoid the 1st and 3rd like the plague. The last one is ok but #4 is basically the same thing with a booster table for longer cuts, take it off and do 90 degree cuts for things like hearts and crosses.
