Default Crappy friction saw will not cut square.

What experiences do you guys have with friction chop saws that will not cut square? I am assisting someone by long distance email and their saw head is out vertically.

My own spark maker is dead on and the saw head permanently attached to its base.

I know some saws can be unbolted and shimmed up to get the vertical square up right.

It looks like this one is fixed and I am suggesting adding another say 1/4" base plate and adjusting that up until its flat base squares up with the friction blade.

The 1/4" is thick enough to accommodate some c /sunk screws and should rigidness the base.

Does any one have experience or ideas ?

Thanx
Oz

My experience with those dumb saws is that when they are forced through the material too fast they wander sideways and produce crooked cuts.

This bloody saw, a Ryobi is 1/8" out while static.

It was measured using a speed square and at full height of the square -about 8" - was 1/8" out.

I was toying with the idea of cutting the appropriate amount out of one of the pivot tabs to adjust the saw blade back to square with the deck.

The idea is to slice the amount out with a angle grinder cutting wheel and tack it and check for square and then weld it up.

Does it sound like a plan?

Sounds like it ought to work. At least if you start square, like Dave says, the rest is not getting too ambitious with the down feed.

I would suggest changing the blade first. An abrasive will cut crooked just like a bandsaw. If it cuts crooked with a brand new blade, then shim it.

If you are cutting stock long enough, you don't need a full pie-slice of an angle on the base to make up for the out. Just tack a piece of 1/8" rod on the appropriate side to kick up the stock to perpendicular to the blade.

The cheaper abrasive cut-off saws do not have very good pivots. I would start looking there first. If the saw has been around a while, the pivots may be toast.

That sounds like a lot out of spec.
Is it out of warranty?
