The only thing blade runout will affect is kerf width.
Not so sure about that. Worn arbors, bent blades, etc could certainly have an effect on cut straightness I'm sure. The effect of cut depth and bevel angle in addition to those issues, I'm not so sure about.

I've checked runout at 90* and it's acceptable, certainly nothing that would explain what I'm seeing. Arbor wear would be interesting, let's go give things a wiggle and see.

Arbor (drive spindle) end play could cause what you’re seeing. What about the bearing / bushing that the saw swings on (sorry don’t know the proper term)? It seems like even a little play there would lead to problems - especially when the saw isn’t swinging in a vertical plane…that seems too obvious after writing it out.

I took a look at 3 2500 gallon water tanks this morning. At $1000 a piece they’re a bargain. Now I just have to load, transport and unload them without killing anyone. It’ll be good practice for the 5000 gallon tanks I have on order…

Is it off in both directions? If so, is it off in the same direction, by the same amount?

"yet".


FT wanted to get Indian food from a truck stop. that boy ain't right ...
If the truck stop is Quealy Dome on route 80... your boy is being smart. Those Sikhs are legit. They definitley bring the real deal. That exit happens to be the one I take when heading to my in-laws out in the sticks.

Methinks I've found it...a bit of slop in the slider bearing allows the assembly to rack at full extension when tilted. If I relieve the weight by picking up the weight of the head, boom, square cut.
That's what I was getting at by those questions. I'm assuming you see the cut drift to opposite directions depending on the side of the cut angle.

Funny you say that, I was perusing the Kapex this morning, though I seem to recall reading a not so insignificant number of folks dissatisfied with theirs for varying reasons. Stuff breaking, hard to source replacement parts, inaccuracy, all issues you wouldn't expect out of a saw that costs that much.

I'll have to make some test cuts with my Dads Bosch glider next time I'm over their house, see how well it fairs.
I have the new Bosch glider. Haven't had to do a glide cut at 45 yet. Full length cut at 90 is dead square.

You probably would, but I seldom tilt the saw to the left. I hate cutting with my non-dominant hand. :D

That's likely what I'll get when it's time to replace this one. But it was free and in great shape, so I haven't had much reason to spend the $650.

In normal use, definitely. In trying to troubleshoot the cause of the cut alignment issue, it would be one of the first things to try.

Cut stays "off" in the same direction = non-flat/square frame or angle alignment issue
Cut moves with side of cut = flexing/deflection of the blade and/or arm

I tried that initially, but the cuts weren't too bad, so I didn't thibk much of it. One of the bearings is notably worse than the other, so it manifests worse when tilted to the right as that bearing takes more of the load. Took a little to run through all the other variables before I got to the bearing.

Now to dish out $60/per bearing. :bad:

Not to be a dick. . . But Jesus Christ your neighbors are close. :bad:
He at least has a nice alleyway (I think, assuming thats the back of the house).

They build them like whats seen below here now, the eaves are pretty much touching. And these are all (or were... :rofl: ) million dollar homes.

:panic:

Get those cuts nice and precise then find out nothing is really square in your house.

Heh. No offense taken. My house is 3,272 finished sq ft on a 6,332 sq ft lot iirc. So yes, not a large lot—that’s how they are in this neighborhood. Better for efficiency and we have enough of a yard.

And yes, that’s the alley. Houses load butt to butt from that alley.
Crammed housing is the thing these days. Stupid large multistory with no yards or privacy
I'll take my 50 year old single story 1700 Sq ft 3 bdrm house on a 10,000 Sq foot lot over that anyday.
That building pattern is why California has such a housing shortage. Which in turn is why there are so many homeless. Boomer mentality.
