SPECIFICATION Review: Not a shill, paid full price multiple times before this review. Great extrusion so far. - Got 40 4ft pieces via 3 separate orders at different times for projects. I consider this to be enough to judge company quality. I work as a Quality Manager at a large precision manufacturing company and order different types of extrusion at least twice a month for various reasons. Keeping this in mind, the following is my thoughts on this 2020 extrusion. FIRST THOUGHTS: Great finish(black), diameter, slot size and depth is within .002" which happens to be the margin of error for the calipers I was using. This is exceedingly good, but expected due to how extrusion is manufactured. LENGTH ACCURACY: Simply stated, it's seems to have been purposely cut long enough to accommodate kerf loss on one or two cuts. Can't say if it's different for the other length options. On average, they measured an 1/8"(.125) long or so. I appreciated this immensely. CUTTING: Use an 80-100 tooth thin kerf blade that specifically states aluminum(miter saw, table saw,ect). Very accurate, clean cuts on the miter saw setup I used. CONDITION: Each piece was individually wrapped and visually straight(good for my purposes). Beautifully packaged, seriously. I order mitsumi extrusion at work that at times comes in scratched up and slightly bent at 4-6x the price and lead time. Perfect finish. Great packaging. TIP FOR REMOVING PLASTIC WRAP: DO NOT TRY TO PEEL IT OFF! It will just shred and turn a 15 second job into a 5-10 min job per piece. Using a knife with a dull tip and sharp edge, flip the knife upside down and place the blade edge facing up inside the extrusion slot, run it quickly down the inside of the extrusion slot at a low angle using your fingers to control depth. This makes short work of the plastic wrap by slicing it off cleanly instead of ripping off small chunks. 40 pc in 5 Mins. I was not solicited in any way for this review. Seriously 10/10. Review: Geek tinkertoys... great to have in stock. - I just used this to build a 10-inch server rack, and it played nicely with all available accessories. Good straight extrusions, easy to cut on a table saw, and as others have pointed out, just use a pair of scissors gliding along the length to cut the plastic packaging... only takes a few seconds. My only mild complaint might be that the finish is delicate... Scratches easily when sliding across a surface. But in practice I don't notice. My machine looks closely related to the 3D printer sitting next to it, and adding things (including piano hinged fixtures and other gizmos) is straightforward. Useful enough that I bought more than I needed to have 2020 available for random projects.
