Kreg Rip-Cut Circular Saw Guide

The Kreg built-in straight edge is only as good as the plywood edge is straight. If the edge is not perfect that edge will be telegraphed to the cut. I also have reservations that the edge does not extend forward any more than it does. If it hits a rough spot on the plywood edge I think the saw would tend to veer towards the outer edge of the plywood. It probably will work good on a straight and smooth edge.

See above.

I'm betting that if you are not satisfied that you can return it. ;~)

Running the Kreg along a bad edge will do the same.

I know. That was my point. It's not a given that the straightedge has that advantage over the Kreg jig nor the Kreg jig over the straightedge. Granted, a T-square would make quick work of checking the edge for either method.

Hey, I'm not advocating the Kreg over a straightedge, just comparing and contrasting, as they say. I think Leon's point of the small contact point is probably the strongest point against it. The homemade track used with a verified edge seems like the best option other than, in my case, the storage of an 8' x 1' track.

Bob,

Invest in a tracksaw, if you have the dough. I have the Kreg and its so lim iting. I would use it to rough cut and then finish up at the tablesaw. In f act, I often do that with my track saw and I own the Festool saw. Getting " nuts on" parallel can be tricky anyway you go. But the Festool and any othe r track saw, is so much better. Good luck.

I do thesame with my track saw, not so much for parallel sides as consistency. I feel better making all the like-sized cuts with a fence (without moving it).

material up to 24 inch wide so not too good for full sheets

There were 2 lines that go together:

Cut materials up to 24" (610mm) wide Rip sheets of plywood in half in just one cut

So, good for ripping a full 4 x 8 sheet into two 2 x 8 sheets, minus the kerf, of course.

Not so good for crosscutting a full 4 x 8 sheet into two 4 x 4 sheets.

Which do you think is done more often?

looks like anything blue on kreg stuff is plastic at least the ones i looked at

There is something wrong with plastic?

Late reply to this post, but I just attempted to use a Kreg guide to make n ine 6" wide slices from a 5'x5' sheet of 1/2" Baltic Birch. By the time I got to last cut I had a noticeable bow in the piece. After checking all 9 pieces with a straight edge I found that each piece was successively more b owed. Total waste of a sheet of birch. As was noted in an earlier comment

- the Kreg will amplify any edge imperfection. I'll go back to using a cla mp-on straight edge.
