I bought a used Ofna truer a while ago and have been using it pretty regularly at my house. A few days ago a racing buddy commented on how rough my truer left my tires after a cut. So I strated looking at the cutting bit on his $400 Hudy truer and comparing ti to the piece of hacksaw blade on mine and decided to see if I could get my truer to cut smoohter. So I went to Home Depot with hope of finding a cheap hacksaw blade with a fine tooth count and found the following . . .
It doesn't have teeth, but rather a clump of sharp points formed of carbide it appears. When I got home I clamped it in place of my old blade and viola! Nice smooth cuts now!
Now a new blade might have netted the same results, but this worked like a charm for me.
Just thought I would share as I know a buch of guys are using the hacksaw replacement. One more option for ya.
