Not a good day .. on my very first cut of the day at 9 am ... i was trimming down a rough piece and making the ends flat to go in the vice ... well the obsidian caught a diamond and bam hooked the blade a little cracked a piece of obsidian off and well thats that .. i used my fingers and bent the small part that wwas dished back a little ... I then cut again but opalite and well the it still cuts but its alot rougher to use now ... so I switched to a very old blade that came with my used unit and its cutting but Iam only doing opalite becauuse the blade seems like it doesnt have much diamond on it and is probably 30 years old or more according to the spider webs and cocoons ... ... but I could be wrong ... How do you really know ? The original blade i bent I cant see any diamond at all on (the raytech green blazer) !!! looks like i learned a lesson ... dont trim with your slab saw !!! Thats my new rule atleast ... cant waste blades every 3 months .. so Iam thinking of the bd 303 now ... oh well

To bad about the blade. What a way to start your day. Why do you trim with a slab saw was it a very big slab? Stu

He has a 10" "trim and slab" saw. I'm guessing pilot error not wrong saw choice.

yeah its a combo saw .. but i think the blade is too big , thin and floppy for really trimming alot ... but what i was doing was squaring off a piece of rough so that it will fit nice and snug in the vice otherwise if the rock moves in the vice it can fly out during cutting ... so sometimes i square the rough up ...well atleast i have a nice 10" blade for trimming now .. lol no need for it to be perfectly straight .. so anyone know how to tell when a sawblade is running out of life !!

Slabs saws can be large trim saw to!
I have 16 Highland-Park trim saw.
Though if your talking notch raytech Blade. their old. and fine to fare blade.
Take a sheet of ply-wood and loose hit the blade from center to circumference on the radius and keep flat hits to blade " Don't ping Blade with hard hits. flat loose hand hits.
Working around the radius to the circumference. Do both side.
where the bad area was trace that side of blade.
And the opposite side. check to see if the blade matches.
Now some blades are wall hangings. for the wife to paint on.
hand fed material well cause a lot of blade damage.
Part of the lapidary game in the hobby.
As for choice of blades i only use MK-Blades. Notched
Centurion, Gemking. standards 297 notched.
though i like notched blades .....over continuous ( Sinter Blades )

Thanks Jake ...

If I get couragious I might try your fix as well .. Thanks again !!!

Check blade rotation, if you can reveres it.... it well back grind the ramp on old diamonds. and expose more new sharp`s - Diamond now are 80-mess syntactic in most standard blades.
