Hi. New here though have been browsing projects for a long while.
Anyway, I decided to buy a new circular saw…or rather a used one that should be much better than my old dead saw.
I ended up getting a lightly used Craftsman 28195 Hypoid 7 /14” saw. Having not used a hypoid or worm drive saw before I had a few questions as I am worried that the saw may be a dud. (Got it for less than $50) Well, I didn’t have a good blade so ended up using a $5 job from harbor freight I had laying around as it didn’t come with one. I put the blade on and measured the foot, blade seems true and distance from edges of the foot are equal.
So I made a test cut on a piece of 2x I had sitting outside…pressure treated and pretty wet but it was all I had. I cut a few inches in and backed out to take a look at the cut. The bottom of the cut looks square but the top half starts to drift and bend to the left. So if I kept on with the cut it would have been bowed. I carefully checked that the blade didn’t have a wobble by spinning it up and it seems fine without a load.
My first question is…do you think this has to do with the blade being crap…yeah it is new and should be sharp but it’s a HF Moly Carb so I don’t know. I am hoping it is just deflecting going through the wood because it is junk and not that there is an issue with the saw.
So my second question…when I spin the saw up it has what I can best describe as a rattle to it. When I let it spin down again with the rattle. My old saw had no brake, so is this normal and associated with the brake? (Like ABS on a car?) The rattle scared me because it sounded like the blade was catching on something in the guard but it is clear. I am worried that perhaps the bearings have gone and need to be replaced but I also realize that I am not used to a saw like this. I understand that there are gears going on, the saw has a brake and the rpm’s are down but the torque is way up…which is very noticable.
Well, thanks for any info you guys have. Going to do a few projects around the house this weekend if weather permits, just don’t want the saw to blow up in my hands.
