Hi Allen, to put the aluminum extrusion precision into perspective it would be interesting to see the same measurements with other stock fence systems.

Cool stuff.. we use to make workbenches out of that stuff when I worked in the semiconductor industry. The stuff has been around for 15+ years.

Hi Allen. Hope you’re doing well. Good health to you since your cancer scare. 👍🏻

Thanks for the review Allen. The extrusions have opened up a lot of doors for me. Thanks again for all you do.

Thank you for sharing such a useful information. My project requires a lot of accuracy in precision, and this video cleared that to about 98 percent.

Thank u for good information. And which aluminium profile should I is use for table saw fence . Pls tel me

This is very informative video thank you so much. One thing is not exactly clear. When you're measuring the profile straightness across the face. One is concave one is convex, and there is no good explanation on that. If the slight tension would be the goal, all would be the same concave or the same convex. Why the difference ?

Perfect information!

I would very much like to know your preferred supplier for this material

For a piece to be extruded and not machined and to be at that tolerance is pretty impressive.

Jesse Fritz Like he said it's the pulling/stretching of the extrusion that makes it straight. It's like when you pull a chalk line or a string for shimming a wall.

Hey Allen, Do you calibrate for a tenon jig, if so how? Is that available as an assessery‎?

Here is a link to the video series on dialing in my tenoning jig. (just 2 videos) 1 of 2 Tenoning Jig Using Linear Bearings/Rail Mounted On Aluminum Extrusions There is not much to them if you have an extrusion and the bearings/rails. The extrusions just make connecting anything like bearing rails a snap.

Can I use some of these for support structure on a 3 meters tall greenhouse with double glass? Would it be sufficient with a 4 x 4 cm beam? Does it have the same strenght on both the long and short side? Thanks!

Miss you Allen - Hope all is well. Check in with us!

What is the stiffest extrusion?

I would be really interested to know, which woodworker does his projects to 0.002 inch? So no reason to worry about the straightness of this material (in my opinion).

Not me Georg. No matter how accurately you attempt to cut a piece of wood, temperature and ambient humidity conditions make for quite a dance in dimension changes. For me what has always been more important than a specific dimension is consistency of cuts as I mill my stock.

AskWoodMan I fully agree; if you cut your drawer fronts all together with the same setting, nobody cares if the length is 0.001 or 0.002 inches off. And as you say: wood is a natural material and expands and shrinks with humidity and temperature. So surely these extrusions are straight enough for any woodworker!

Love all your stuff brother slight annoyance the letters-wording takes up a good portion of the screen and since it is already in English to English is it reallyy needed.?? anyway I send every good wish from Scotland excuse typing parkinsons problems. Alistair

I know it's irrelevant, but a light beam deflects due to the effects of gravity - so even a laser beam isn't actually perfectly straight.

Actually, Scott's observation doesn't change things at all... gravitational fields may "bend" space, but straight paths contained in that space nevertheless remain "straight" in every measurable sense of the word. Laser beams, too.

The bend on the laser beam would only be approximately 2-3 angstroms.

Hello WoodMan, Based on your extensive Metal experience, I am hoping you can guide me to some information. I am planning to build a frame for a CNC machine, using 4080 and 8080 extrusion from 8020. Extrusion is light, bolts together easily, but expensive... I was considering using maybe 3 x3 tube steel... which would require welding, etc... and I would obviously need to choose the wall thickness.... First, I cant really find any specs on the strengths of the steel... so it makes it harder to choose. The extrusion is like a web, which seems to increase it's strength instead of just a tube... Second, How straight/or twisted does steel usually come compared to extrusions?

@AskWoodMan

Steel is very strong and straight. It does require holding the pieces in clamped jigs to minimize distortion to the intense heat of welding. Steel is what I would make a sub-frame out of and save the extrusion for when you really need the connection points with fasteners. There is info a plenty about all aspects steels strength available online.

Heat distorts metals. Don't underestimate the power of welding heat to distort a project into a useless art project if your end goal is any kind of precision. Welding is largely used in cases where large tolerances are able to be dealt with, or the heat effect is precisely engineered into the product. In the scope of DIY CNC machines, if you're considering welding, you may a well consider using two by fours and plywood. Unless of course you are an expert welder and know how to precisely manage heat and distortion.

Lasers bend due to gravity 🤙🏻

If the gravitational pull exerted is of great enough force but not on this planet without increasing that force via an artificial method.

Well, your length of measurement is only what, 50"? So you think light is going to bent from one end to the other with the effects of gravity across about 4 feet? ha, ha.
