How To Joint & Plane Large Boards on a CNC 

First, let me say I've been a fan of your videos for years now. Love your work, hope you keep doing it. That being said, while this is a cool process, it's super wasteful. Now, for woodworkers like me - hobbyists really - there's no way we could spend our resources this way. Also, we don't have CNC machines. Well, I don't, at any rate. For anyone wanting to take a twist that extreme out of a board that wide, while retaining as much of the wood as possible, here's the solution: 1) Rip the board down the middle. 2) Remove twist from resulting boards. (the twist will be much less extreme.) 3) Plane to matching thickness. 4) Match-plane boards to join back together. 5) Glue boards back together. (Bonus: if you know you don't need that long of a board, crosscut to rough length first. This will also take some of the twist out of the board, maybe most of it.) This process can be done with a planer and a table saw, just a table saw, or hand tools. Done with power tools, it will take about the same amount of time as stated in the video. With hand tools... Just a bit longer. I hope this is useful for anyone else out there who doesn't have the equipment or resources. Like I said at the beginning, I'm a fan of your work. I look forward to seeing what you post next. Hope you and the family are well.

Protip about hot glue. Use any type of alcohol, anything from rubbing alcohol to vodka will work. Just bush a bit on and the glue will just pop right off, even on porous materials like wood.

Would ripping the timber in half then planning followed by thicknessing finally joint the two pieces together be quicker and waist less timber.

Great video describing a technique fo planing a large board. I would be interested in a companion video that describes edge jointing.

Hi Darbin. Good tip for using your cnc but you can use your planer also to get the same results even faster. Screw your stock from the underside of a piece of melamine using wedges and making sure the screws are countersunk and lie well beneath the surface to be planed. Once the surface is planed completely, unscrew your stock, flip it over and run through your planer again until you surface the length you require. You can then cut the board to length and then plane the remainder of your stock to a thinner thickness.

Brilliant, craftsmanship is not dead.

I am really amazed by the hot glue trick, I didn't expect it to hold. I am going to try that 👍🏻

Might have been worth trying to flatten the twist before surfacing.. I've seen soak with hot cloths & clamp to solid surface, increase the clamping pressure, then let dri still in clamps.or split to strips / quadrants, surface individual and reglue

Very insightful video. The surfacing bit works very efficient and with nice chips at the right feed and speed. I think your rpm might just be way too high. On my CNC I use the surface bit at 3000 rpm and maximum feed and get beautiful chips and no dust...

If you make a sled for your planer, you can wedge and hot glue boards just like you did for the CNC, so you can use a tool with a much higher material removal rate and be done faster. The sled can be a simple flat board or you can make a torsion box that will be really stiff and flat. As a lot of others have said, alcohol is the solvent for hot glue, which can make getting the board unstuck much easier.

Great way

I am missing your--*Hi I am linn and this is darvin orvar channel* Love from India

Just found your channel and I'm surprised about the glue trick. Thanks.

Plastic nails with nail gun could be useful here. I learned about this on Stuffmadehere's channel. I don't know if it works on all wood though.

Really awesome tips, Linn! 😃 Thanks a lot! Stay safe there with your family! 🖖😊

Great video thanks, one question, Panasonic auto focus?? :D

I've used my CNC for planing some years now, and it really works well. I suggest making holders which attach to the side of the piece, then glue isn't necessary. Right now I'm working on a sleight for the CNC so I can plane 4,5m planks. The problems you get when you have a sawmill... Edit: I find it odd with so many suggestions of holding the wood in place, though the first thing I made after finishing my CNC was holders for the side of the wood. Am I the only one doing this?

great video, but also if you only needed the 1/2 of it, you should have cut it first instead of trying to flatten it then cut it afterwards

Great tips. That finish looks nice too.

Here is a Tip: If you cut the length of the board first it ends up less of a bow and then that's less you have to take off to flatten.

Interesting video! Great way to utilize the maximum amount of material.

Thanks for the video!

Always good to see you, dear.

Ah, that reminds me of days of jumping on bent planks so cnc vacuum can hold it. I must have looked like maniac

Olá bom dia. Adoro teus vídeos. Santa Maria RS . BRASIL

Good tips.

I always like your videos.

Hi what is the spindle that you use for your cnc machine?

Thanks for the video it provides some good pointers on how to work with uneven surfaces. I spotted some software you're using "WARP 9", how does that fit in your CNC?

Interesting observation about the chips when using surfacing bit. It makes sense considering the different geometry.

Curious as I don’t own an avid cnc, but how did you find or define the zero for x, y, a each time before starting the run?

Woww💜💜

👍👍👍

WOW, woodworking!!🤔
