Difference in tension ?

[Foxfold]

I tried cutting a piece today that needed a 'finer' blade than my normal go to blade (#3)  -  so I chose the next one down (#2). Now,, I liked the fact that it has a much smaller kerf, however, I find it difficult to make it go where I want it to go as it has a tendency to 'wander.

Now, is that because I'm not experienced enough with this blade - should the tension be tighter than with a larger blade -  does it need to have the saw running at a slower/faster speed ?

Questions, questions !!!   All because I don't have enough knowledge     Any assistance gratefully received.

I add tension when I reduce blade size.  I also reduce speed either feed or saw speed for additional co trol

I always keep a high tension no mater what size of blade. I see no reason for lower tension on smaller size blades.

When I have problems with the blade following the line, I will concentrate on the line going into the blade, not the blade following the line.  I also slow down some, and sometimes set a lower speed on the saw.  Other times, I just go into the house and sit down with a good book.

The smaller the blade the thinner the metal of the blade and that is what wanders on you. You have to slow the feed rate somewhat but the difference between those two sizes should not be drastic unless they are different brands. Do not reduce tension.

Along with what everyone else has said, it can be the blade.  I have that problem with FDUR #3, as soon as I changed to Pegas MG #3 I had no problems with the blade wandering.

I found that just drawing a new line where your blade went works real well... makes it look like you went where you were supposed to go..

I believe you need to slow down your saw speed for a better control.. Those real small blades will flex easier and if you push too hard on the piece it'll flex the blade.. They can be like a spiral blade to an extent where they will try to wonder into the easier cutting wood.. they'll drift into softer grain..especially cutting in the same direction of the grain..

#2 and #3's etc are not generic. THey also come in different sizes, TPI etc. 

Get a different #2.
