Precisio CS 70 accessories needed to cut a board?

[bindestreck]

Hi I am a newbie. Just got a CS 70 and need to cut a massive board some 200 x 70 x 3 cm into two pieces 200 x 35 x 3 cm. Trying to figure out what I need to buy.

My guess is that I need a CS 70 ST and possibly a couple of FS-HZ 160 to keep the board in place, but would that be enough? Do I also need table extensions and possibly CS 70 LA?

Greatful for any help

CS 70 ST

FS-HZ 160

This is what you need: the side table extension, the rear table extension and the CS 70 LA fence. The slider on the left does not work with such big pieces, but only smaller ones. Still not that easy to cut a full board, but I manage. Easier with a helping hand. It is still a lot easier to pre-cut boards with a TS55 circular saw.

You can't keep the board in place, it has too move through the blade, so no clamps needed. They are only very usefull with smaller pieces because there is a slot in the table where you can fit one in.

Thanks! Itching to use the CS 70, but I also have a TS55 and - yes - that is of course the better choice.

Ok. I meant clamping the board to the moving smallish table running on the CS 70 ST rods.

Since you are only _ripping_ down to a width of 35cm you should be able to rip that board right through without any problems as long as you have the LA fence and an outfeed support - and the side extension just as Alex described it above.

There is a certain techique to ripping boards but I am sure you know it already. You don't need the sliding table and I would say it would even increase the risk of drifting the material when ripping. What Alex showed in the picture is all you need. If  you don't have the rear outfeed support (which is a bit short I think) you can set up a support of your own, make sure it is a mm or more below the surface of the saw so you don't catch the edge.

Don't forget that you will not be able to get two 350mm rips out of a 700mm material, the blade will take off a few mm's.

If it was me I would rip it twice. That is how I did it when I had the CS70 and that's how I do it on the large format saw I have now.

Once at the "calculated" center, taking the blade into account, and then rip the two pieces through again, shaving a half (or even a full) mm off again from the narrowest of the two and then the widest. Then you will have two boards with exactly the same width and a fairly clean edge on both pieces instead of two "almost" identical boards with rougher edges.

Even with the format saw that can be set down to a tenth of a mm repeatedly the error is much greater in the feed through process so if it is critical I always rip twice even if I can split a board in two halves to within less than half a mm on the first go. 

If the rip blade gives a perfect cut and the off cut ("left over piece") is slightly larger I just rip that again at the same width setting so it is exactly the same as the first "keeper".

If the off cut is slightly smaller I need to rip them both again as that means I have to reset the rip fence to trim the smaller one and the first one to the same width.

I missed that your board is only 70 cm wide, I thought you meant a full board of 122 cm. 70 cm wide is going to be a lot easier than a full board, but the problem is the CS70's table is just a few cm short of 35 so you'll have to have the side table. Or just make a small extension with a wooden fence and clamp it on the table.

If it's only this one cut you'd have to make I would never buy al the extras, that's a lot of money. You can easily cut your board in half with the TS55 if you have a long enough rail.

As Henrik said, you can make your own outfeed support for the CS70, or you can just ask somebody to help you support the piece when you cut it. I agree with Henrik the outfeed table is a bit short and I've made my own support like a saw horse that I put behind it when cutting long pieces

I have the full set version, and though I mostly use it without all the extensions, they come in handy though when you need them for bigger pieces. But I really never use the slider table. I don't like it, too bulky.
