Help Ripping - just got my first sliding table saw. Felder k700s
Ok, so if you're talking face frames, then do as Mac suggests (& i stated in my other post). Rip over size and dress. I will assume your material is 4/4? Rip first, dress second. You can also rough cut material into shorter lengths, cutting your longest lengths from the straightest pieces. This of course will be more time consuming, but may be necessary if you material is less than ideal in its straightness. The problem you may run into depending on the species, and how it has been dried, is the stresses in the board might result in very bent pieces after ripping them down in size. This can vary from one board to another, and from one batch to another. Based on how much each board moves, you might need to make a wider rip, so you can get a straight edge on the jointer. Next joint the face, then the edge of each board. They are now ready to run through the thickness planer to get them perfectly parallel in width and thickness and exactly to the required size. Being face frames, some amount of bowing might be acceptable, in which case, you might be better off dressing all the material in the longest lengths possible, and then cutting to the required lengths. Remember, always cut your longest lengths first!!!

Hope this helps.

Hullo all- very informative thread, thanks to all the contributors! I learn a lot here.
I recall one member posting that they precisely cut a square of MDF, set it against the left fence, and now you have a registration surface for ripping narrower pieces. (Can clamp the mdf to the outrigger so it doesn’t shift). I made one of 3/4”, 500mm square, so I can use the flip stop to set rip width by adding 500. Works really well and as long as the two ‘good’ sides touch nothing else, has stayed true for a lot of use. Costs nothing :-)
Cheers

开云体育For Lucky’s overhang method, I just use a block of wood with a pencil mark indicating the cut line. Push block against end of the slider and at least cover the pencil line with material being cut. Quick and easy.I also installed an overhead laser to assist with the first rip on rough lumber. It used to be overhead on my KF700 and worked great but it is on the wall perpendicular to the saw now for my K975. It is not in line so it casts an oblique line. This means it only works if it is calibrated with same thickness as the mattering cut. On my list of things to fix.

Hi John: ? You make good points about both the use of a bandsaw and thicknessing on edge. And with regard to the slightly ‘out of square’ issue. It is very minor like you say, but enough to notice.

But it works for me.) ? There is another technique that I’m not sure has been mentioned much on FOG. I sometimes parallel rip on the slider without a parallel fence by measuring the overhang of material. Here are the steps: ?

开云体育Hi David: ? I’m pleased there was something helpful in there. ? I’m guilty of not even thinking about sheet goods, and yes, I do use primarily solid wood. Bryce makes the excellent point about straight line ripping which is important of course. ? Your question about width is important, and it relates to length as well. I’m quite happy to rip short stock (up to 1200mm long) on the right side of the blade up to 300mm or even a bit more. But at some point there is a change-over: ?
?
? Examples: ? Cutting larger sheets of processed material are nearly always done on the left side of the blade. Material is more often wide enough to register against the cross cut fence. The exception comes for ripping smaller dimensions (less than 300mm) which I almost always do on the right side. For short, narrow dimensions, I tend to switch to the right side, unless there’s a lot of repetition, in which case setting up for parallel ripping is worth the effort. ? Long stock, 2m and longer, I would never rip conventionally, unless it is narrow and ‘floppy’ (like 50-100mm). Sure I can straight line rip the stock to get one side straight. But feeding such long stock manually cannot be done with ‘perfection’. There are inevitable pauses associated with manual feeding, and it is arguably impossible to keep such stock against a relatively short rip fence. The inevitability of a less-than-perfect rip cut becomes more ‘locked-in’ with longer material. ? Large glue-up sections are always done on the left side of the blade. When sizing a rectangular table or desk, work on the slider. Always. ? Sorry for any repetition in my many posts today. I’m procrastinating. Time to get back to work. Thanks everyone. ?

[email protected] <[email protected]> on behalf of John Hinman via groups.io <jhinman1911@...> Kamal, ? One way to get parallel rips is to set the fence parallel to the cut and use it for a bump stop. Eventually your 12” board will be reduced in width to a point where you can no longer clamp it to the sliding table, though. ? For narrow rips you do not really need fancy parallel guides. Simply clamp scraps to the slider to serve as parallel guides. You’ll spend more time fiddling around getting them set correctly, but it sure works. ? Lucky, instead of measuring from the edge of the slider to see where the cut is I made a simple gizmo as shown. One stick fit to the slot, and a thin scrap of ply glued to it. Put it in the slot and trim it with your rip blade and you will know where the edge of the cut is. Precision is limited by slop in the strip in slider slot and by any variance in the slot itself, but it is really close. ? The hole lets me hang it on a magnetic hook on the side of the saw, handy for use. ? -- John Hinman |
开云体育Sounds good Mac. Your words sum it up well, especially ‘being skilled’ and ‘being damn careful’! ? Warm regards, Lucky ? ? From:
[email protected] <[email protected]> on behalf of mac campshure via groups.io <mac512002@...> So I’d recommend when ripping to set the fence to end at the back of the riving knife. Lay the fence on its low side.. Straight line one edge Stand next the the blade guard on slider edge and jam the stuff through ripping oversize take everything and size it thickness on the planer on edge. If your nervous use a push stick. If you’re skilled at it, you can use the slider to push the stuff through, but be damn careful that you don’t get anything trapped.

Jonathan, thank you very much for posing the question as have been struggling with how to rip down material specifically for face frames.??
John, your suggestion on rough ripping on a bandsaw and then finishing on a JP was a light bulb moment for me.??
David, your attached article was also incredibly helpful and has given some ideas and think I understand the approach I need to take.
?
OK, question for the experts here as still a tad confused on left or right side of the blade and where to slide the fence, etc:? I have the K700S and would like to:
?
-Rip hardwood 4/4 boards that are 5' long and roughly 12" wide into 1.25" face frame material and accuracy is of course critical.??
-I do not yet have parallel fences (Lamb Tools) and want to learn how to make these cuts without the use of one.
-Same comment as above regarding a FF jig.
?
Much appreciated and Gratzi,
?

开云体育Greetings: I normally cc first selecting longest length always trying to work with smallest parts.If you can do hit and miss first that will help with matching color and grain. You can also specify hit miss from the yard. The other thing with cc first as you get rid of the ends that screw up your knives. Keep steel brush around to clean surfaces.

Lucky-
That was excellent. Thank you for taking the time to write such a detailed explanation, I understand significantly more now. I notice that you discuss the length of the work, but not the width. I assume you work primarily with solid wood? Is there a width at which you would switch sides of the blade? I’m not referring to aspect-ratio here. David |
Ok, i'll try to add something to this topic.?
It depends......
What are you trying to rip? How many? What thickness? There are so many questions that need answering before an answer can be given.
Here are some examples.
If i need to take a bunch of 6, 8 or 10' boards from roughly 6" in width, and make them all straight and say 5 or 5 1/2" in width, then i would start by making a straight line rip with the rip shoe on one end of the slider and holding the other. I would have the rip fence set to my desired width, and simply rip the board down.?
If i am doing a lot of ripping of solid timber and i'm not just ripping a small amount off the edge, then i will always be using the short fence. Not only does this lessen the chance of the timber binding on the back of the blade if there is tension in the board, but allows for better accuracy of the cut when that tension is released.
If you are talking about sheetgoods, then you will have more accuracy sticking to the slider side. Having said that, i do all my thinner "rips" (say under 8 or 10" wide) of sheetgoods on the right of the blade. Good technique will get you a perfectly good result.
With all that said, i will pretty much always be ripping solid wood as a first step in the machining process. From there i will be square dressing the material and or running it through the shaper for use in whatever it is i'm making.
Let us know what kind of rip cuts you need advise with and i'm sure you will find lots of good advice.
Regards,
Bryce

开云体育Ahem, I rip on the right side of the blade all the time on my Kappa 400. ? Yes, we consistently get a better finish (cleaner cut, more consistent, straight) when using the sliding table and a mixture of clamps and jigs. However, that mixture of clamps and jigs takes time to get exactly right. Not a lot of time, but enough time for resentment to build. ? So here are rules of thumb I use: ?
