Morso knives problem

[camacho]

Hi can anyone out there help me !!!!!! I took my blades away from the morso which were working fine!!! when i put them back one slightly touches the bottom knives as it first makes contact, i have cleaned the back of the knives and the morso head but this still seems to happen. Do i need to adjust the bottom blades?

Hope someone can help

Nige,

Since you didn't have the problem before blade removal, I would suggest that it is an alignment problem.

The blade that is now rubbing may have been pushed out of alignment when the opposite blade was tightened into position. Try loosening the culprit blade and letting it settle slightly toward the floor and re-tightening. Do the same with the blade that is rubbing. It only has to be out of alignment a couple of thousandths of an inch to be a problem.

Ditto what Vince said. Keep in mind that the goal in aligning the blades is to be sure the vertical leading edges (the ones that face you) are perfectly smoothly aligned with no gaps from top to bottom and one not protruding farther than the other. The heights should also be equal, so that when you inspect the part where the two come together at the bottom of the vertical they are at the exact same point. This should result in both knives being perfectly spaced from the stationary part of the blades.
To achieve all this, I like to put the blades on with the bolts finger-tight, do whatever minor adjustments are necessary, then first gently tighten the center bolt on each side. Recheck the alignment. If all is well, gently tighten the front bolts, then the back ones. If all is still well, snug up all the bolts and you're good to go.
Test the cuts on scraps of several "sensitive" profiles to be sure you are getting a good cut before moving on to your "real" frames.

I prefer to tend towards a small gap at the top, that way I can be sure that the points (where the actual cutting is done) are tight.
