Our vibration guy had a belt hog...@1600 bones I think its really crazy for what it is.
I have levels and straight edges...never an issue.
Just curious if anyone has ever used one and if they liked it more than the old straight edge or string.
I would consider one if I could find one for around $200 but they all seem to be upwards of $1000 (which is crazy to me).

I picked up a Bosch 6" torpedo level with laser($40-$50). I use magnet on opposite pulley with markings on it to account for the distance that the laser is off of first pulley. Then I check on backside of pulleys too. It works out awesomely. A ton quicker, more accurate and cheaper.
I used a drive cleat the other day. It was an old drive and checked good on the torpedo.
I was wondering if I could use a laser level and make my own targets. Seems like it works for you guys. Ill give it a shot.
There is a need for a folding straight edge for sure. I was crammed in a smaller commercial ahu the other day and struggled.
I have always tried to sight the belt(s) and pulley edges by eye. You can 'usually' find the plane of the edge of a pulley, and see how it corresponds to the other pulley. Becomes less accurate when one pulley has (much) more material outboard of the sheave, (but most of the time you can measure this). Measurements need to be taken with it running, and always be on the alert for the casting of the pulley to be perhaps true and straight for the sheaves, but the face is crooked, (even a billet has had the face crooked for me before). This will screw you up if you ck. when NOT running. That's where a torpedo laser level CAREFULLY placed against the side of a running belt can further reveal tidbits of misalignment. Thanks for the great info- I'm in the market for a new level now......
It's OK, I'm not speaking to untrained risk-takers. Just addressing those times when you must diagnose beyond what's considered 'normal' and sharing experience. No harm. Of course screwing around with running belts is inherently dangerous! My job sometimes involves dealing with troubleshooting problems inherently complex- where the 'typical' cannot be found. Just sharing- it's all good.
Here's a small laser that will get you started.

Why dont you go to amazon.com and buy a cheap pen type laser pointer. Lay the pointer in the pulley or sheave and I would almost bet money that it will be as close to spot on as we need to be.
Think of it...... straightedge....string...... pulley narrower than sheave......... lot of variables involved..... and Id say that most manufacturers of laser pointers have that laser diode in there to where it is pretty much shooting straight out of the pen body...... or at least straight enough for lining up two pulleys.
Want one with a straight cylinder body though....... so it will sit square in the pulley valley.
Someone try this......... I bet it will work fine.

I attached a piece of magnetic business card sticky to the base of the laser so it would stay on the pulley and painted the rest of the colored pins white, so I'd have spares.
JUST A LITTLE CLOSER AND THE LITTER BOX IS ALL MINE!
Straight edge and your eyes are more than enough for most blower pulleys imo. Laser alignment tools seem more suited for coupled pumps i think. Alignment on those can be really critical in most cases I believe
