I see two options. On is a regular edge clamp in a 99in length. Sold by Rockler and Peachtree for about $114 plus shipping. I just got a free shipping coupon.

The other “uses 50”-56 rails the connect together and use a sort of C-clamp like clamp. On sale at Woodcraft for about $68 plus shipping today and tomorrow.:

It doesn’t seem to have a good way to ensure it is square by itself. However, it has an optional angle alignment tool:

It is about $33 plus shipping with the sale.

So, the second option offers more flexibility (it can cut angles) and be used as two smaller guides. The first is going to be easier to use accurately for ripping. I already have a 4’ version of the first. With the shipping and sales there is aq $4 difference between the two.

Which is the better way to go?

I use the Emerson clamping guides (top photo) in shorter lengths, but I built a shop made version for 8’ cuts. It is just a 1×6 MDF fence glued to a 1/4” plywood base. I made mine 10’ long, and trimmed it to fit with the circ saw I use for trimming. It has the added advantage of indicating where the blade will cut.
Mine is similar to this, but the thin 1/4” base maintains more cutting capacity.

Just set the guide to your cutline and trim away.

the first track you mention also has accessories for your router and circular saw to be used as a track saw. Never used them but have always wanted to. Might be something to check out and help make your decision.

Dorty, both have the options for a guide that runs in the tracks. However, they generally have bad reviews and I don’t want to cut into CF base of my circular saw.

An alternative is to have HD do the long rips. However, their blade is garbage and has lots of tear outs.

pinto, I could do that with two S4S pieces. However, I would have made the base under the circular saw wide enough for the whole base then cut the slit in the middle…effectively making it zero clearance at top where the tear out occurs.

Shop made is the best.
Nothing manufactured even comes close.
Well, except for a big slider table saw, but that’s way out of my budget.

Either a one piece guide or shop-made. Every single two piece guide I’ve seen flexes at the joint so you never get a straight cut.

Shop made is the way to go. I have an 8 footer and a 4 footer. I had one for cross-cuts but I took it apart and used pieces of it for something or other. I need to build another one. :)

Festool plunge cut saw, nothing else compares. One can use any homemade or other commercial products, but you will get splinters, especially on plywood.

Having only a small basement shop, the one piece unit would be a storage issue for me, unless I attached it to the ceiling. You’re taking a lot of money for a one trick pony. JMHO : )

hammer you are right and also dead wrong. the festool plunge saw if an absolutly amazing machine. I have used the Emerson clamping guides pictured above for years, and have never had any splintering. I have cut tons of doors and plywood without any trouble. you can also use them for a router.

The Emerson comes in a regular and a wide. Is there a preferences?

Are the saw guides needed, or can the circular saw be reasonably just held against guide?

The wide one is actually less expensive than the narrow one. Emerson says the wide frame adds extra stability in longer lengths.

I don’t own one of these, but it seems promising…
zero clearance inserts are standard and replaceable.

One day I realized my straight edge was not straight. I got this and has done very well.

Loren, I have the Kreg version of that:

The one you pictured looks more robust:

However, with that one I’m wondering if it is tricky to get started with more than half the unit off the work piece. With both I was concerned it would be tricky to keep straight for a 78” or 96” rip.

Am I making this more difficult than it should be? Will the tool I have do the job? I was thinking the clamped edge would be better for the long rips.
