ripping a live edge slab
« on: January 04, 2015, 12:03 PM »
I'm looking for some pointers on how to rip a 3 inch thick live edge slab.  I have a 10 foot long slab that's destined to become a dining room table.  Unfortunately, it's not wide enough per my significant other.  I'm planning on ripping it down the middle and essentially making a panel out of it by gluing in another foot wide 3 inch slab in the middle.

I thought about using a table saw but I think it would be nearly impossible due to the weight and size.  I have a TS 55 but won't get through the full thickness - maybe making a cut and then flipping it over?  I'm worried that I won't line up the 2 cuts properly.  Of course this might be an excuse to get a TS 75....

Any tips would be appreciated!

A TS 75 on the guide rail will only go 70mm deep. That's 75mm - 5mm for the guide rail. It's about 2-3/4".

A Trion or Carvex with a 140mm blade and guide stop can do the job if the blade guides are set up properly.

When I have done this with my 75 i always flipped it and had small amounts of plaining to get a nice joint.

Since we cannot get sword saws here in the states, has anyone looked into the prazi sword saw add on.  You can install it on most worm drive circular saws.  Other than that, you need a big beam saw.

You could rip it with your ts55. Then true up the cuts using a router and a strait edge guide. just use a 2" strait cutter with the strait edge, then flip it over and use a bottom ball bearing bit that's long enough to ride along the freshly cut edge to finish off the rest of the face.

If I have to cut a thick piece from both sides to make it through and the cuts don't line up, its because I was in a hurry and didn't pay attention to which side of the pencil line the blade was supposed to go. Very rare since that mistake really ticks me off.
Take your time you can do this.
Draw your line on the top side, transfer down to the bottom side with a square for reference but don't actually draw the bottom line, cut the top side, draw and adjust your bottom pencil line based on how your top cut ended up running, cut away;
The key is to pay attention to blade position to the pencil line or guide rail position to your lines; unless you are an idiot (you are on the FOG so I'm assuming you can't be) you aren't going to screw it up drawing your pencil line, its a positioning issue
So often people don't think about the fact that your blade can end up centered on your pencil line or to the left or right of the pencil line; this also holds true for guide rail clamping, minute differences make a clean cut or ridged cut
You can use the 55 and a Trion with a long blade. That works fine but you should use your 55 on the top side and let the Trion cut the bottom. Depending on how well or not you cut using this combo there may be a lot more work in flattening the sides to mate the insert piece. Mating is another story though
On the other hand its an excuse to buy a 75 and then cut the last 1/4" with a good handsaw

I would jigsaw it then use router with straight edge and spiral bit to straighten edge (if you don't have some combo of guide rails to give you 10 ft. of length).  Just make sure the edge is as square as possible to the other sides.  After you fit in the board though, you will probably have to do the same operation on the ends, meaning you could leave the middle piece long on both ends because you know you will be trimming the edge afterwards.

A Trion or Carvex jigsaw with  S145/4 FSG, 499478, will do this in one pass using the guide stop. It has to be set up properly and use the max orbital.

It makes a nice, perpendicular cut 4"+ deep in hardwoods.

It runs on the guide rail and keeps the cut running straight.

Got it.  For some reason I thought you meant those stops that you hook into the rail to prevent the tool from going past a certain point.

Probably just a translation issue.  The limit stop is the Rückschlagstop (literally kickback stop), and the guide stop is the Führungsanschlag, where -anschlag in this technical sense also gets translated as "stop."

It's odd wording but that's what Festool calls them...

The guide stop is for the Trion.  You already have the rail adapter base for the Carvex.

I would use the table saw for sure. But possibly you only have a little bench top table saw? With a proper out feed table its not a big deal at all.

You may not have this option where you live, but if I had to make the glue line cut you're describing in a slab that thick, I would load it up in my truck and take it across town to a local shop that has a Schelling beam saw.  They would charge about $20 to change the blade over and make that single cut, to a laser line, but it would be quick, and most importantly, clean.  I would also bring the new slab to have it cut to width, perfectly parallel.  Those two extra cuts might add a little more machine time, maybe five minutes.

I realize this solution doesn't provide you with the excuse to buy a TS 75, or any other tools.  Sorry.

I sure would not.

I like the idea of cutting to limit of the TS 55.  Then finishing from the top with jigsaw or hand saw.  The less that slab is moved after the partial cut, the better.  That is one of those projects where I always figure lawman Murphy is always looking over my shoulder.  I am sure that is a great looking slab.  One wrong move flipping to make second cut and there goes the ball game.  Making the cut on a table saw (remember, that is a live edge slab.  I am reasoning it is live edge on bothe edges) is possible as long as the operator is very skilled and has a very good (sawyer's) eye for lining up the cut right at the very start.  If someone is not used to making such a cut, there are all sorts of troubles to get into.  A 10 foot by 3 inch slab has got to be quite heavy in anybody's language. It was not mentioned what wood the slab is, but I bet it is not Balsa.  Not even Sitka Spruce.

Why would he have to flip I thought this was only 3" thick? I have glued up stuff like this many times. I just guess my table saw is set up for stuff like this. 10 foot is no beg deal and a 3 Inch slab, I have a ship full of them in everything from Cumaru, Walnut  to Wenge. OWithh my Forest Woodworking blade blade I would have this ready for glue up right quick.

Where do you live, no one does anything here for 20.00. I would charge a 100.00 to come to my shop an take my time like that. And I am betting most companies wont even deal with something like that. What if they screw that piece up, then they are on the line for the material for a 5.00 profit? Actually, I dont think I would even take the piece, there is no upside for me as a business. For FOG friend maybe not someone off the street.

Owl hardwood would do it, with a 2 week lead time. But only if you purchase from them and they wont guarantee a glue joint.

He said about 10' and 3" thick, I can't find reference to width or species. I am guessing 18-30(max)".

Could find weight here if we knew more:
