circular saw weirdness
« on: August 07, 2017, 03:17:23 pm »
Have a weird issue with my circular saw happen yesterday.  I need to make an angle cut in a piece of plywood that's wider than I can use with my 12" table saw.  So I set the angle on my circular saw, clamped down a guide board, and then started the cut.  The cut is ~27" long, and when I got to about the last 8 or 9", the saw started to pull away from the guide.  I stopped, moved the saw back, and tried again.  Same thing happened.  I don't see anything obviously wrong with the wood or the saw.  I would think if the blade was warped, that it wouldn't have cut straight at all.  Is it possible that once it gets hot it's warped or something?  Luckily it pulled away, so the piece of plywood should be salvageable.

Thanks,
Eric

Was the board being fully supported on the offcut side?  Possibly binding towards the end of the cut causing it to pull out of straight.

I was only trimming off < 1 inch, so I don't think that's the issue.

   A fine toothed blade will do that when they get dull, or have damage,  A new blade most likely will fix that,  I have also noticed that the guide plates are remarkably flimsy on some saws and will actually bend and or flex  when you get some pressure on them, especially while attempting an angle cut like that ....  That's better done on the table, or jointer.

It is a fine toothed blade, so I will check that out tonight.  I think I have a unused not-so-fine tooth blade, will try that on a scrap piece of wood first.  :)

    Fine blades are slow and driftey  (<?) by nature anyway, a few less teeth cut faster, last longer, and still leave a nice finish cut.... Don't get hurt friend, that's NEVER fun.
