Anyone know how to make a chop saw cut straight?

MK, I was very impressed with the performance of these precision bandsaws when I was at the 06 Fabtech show in Atlanta.I was cutting .060 wafers off of a 2" diam solid rod over and over again.http://www.femi.it/ENG/Frame/setframelineaprodotti_TAGLIO%20METALLO.htm

Make sure the blade is rated for the max speed of the saw.

 

I know a lot of folks would think that this comment goes without saying, and I've been fabricating and tinkering with metal cutting devices for over 20 years So you think I would REALLY KNOW... The other day I had in my hand while waiting in line, the WRONG blades for my chopsaw... Always make sure the blade is rated for the machine... Good advice Darrel. :2thumbs:

Heavy, I used the HF chopsaw to build my frame connectors. I used a protractor (not the one on the saw) and a square to set and check everything. A couple of times I had to use a length of metal to keep the blade from pushing to one side untill the blade was set in it's cut.

Everytime my work gets a new purchaser 1- they always want to "save" the company some money. 2nd, they got a good deal on the blades because they fit the arbor.

 

 

Not all people think about the right blade for the saw. Their first consideration is price after they figure out if it will fit.

 

The higher speed blades are reinforced much more than the low speed blades.

In my Carpentry days I purchased 2 Ryobi Chop saws. The larger one 16" was for cutting big Crown moldings, and the smaller 10" for general use. Since I had a need for cutting some metal stock I purchased a 10" abrasive cutting blade and replaced the wood blade. I have had no problem with straignt cuts through metal stock. Don't force the blade and keep an even downward pressure. However, when I need to get things done in a hurry, I break out the Plasma cutter, and things are all better!

That comment Stagefumer11 had is spot on... Thanks man!!!!

 

I went out and looked at a blade I recently sent to the scrap heap... It would not cut straight... I looked and saw that the reinforcing cloth was bunched up on ONE side of the blade edge... It was definitely wearing more quickly on one side than the other.... That was probably why that blade was cutting crooked... It was beveled to one side!!!

 

Thanks Stagefumer11 !!!!

 

The beveled crappy blade was a Dewalt brand from Lowes...

I also had problems with a Dewalt blade that stated on the label it was a "long life" blade... It would get hot and stop cutting on anyhting but the thinnest tubing... I also tossed that one in the scrap heap...

 

Hmm... 2 bad Dewalt blades... I think I will try Harbor Freight cheapos next...

Alot of good posts here already, topic pretty played out already but heres my 2 cents.

 

The chops saws are not very precise but I have gotten some pretty good cuts out of mine if I take it slow. Mostly I have used a hand held angle grinder to clean up bad ones.

 

The band saw and cold cut saws are the way to go though for nice clean cuts without all the noise and mess.
