KOP Aluminum extrusion

[customh]

What is the trade name of this stuff and where does one get it? (see attached pic)

[Enigma's puzzle]

Is that x channel?

I believe that is known (around here, anyways) as 80-20. As for where to get more, one source is (I believe) named in Section 10 of the Manual, in a nice handy chart of suppliers.

You should check out Bosch and 8020. 8020 has alot of local places and isnt very expensive.

its called 80-20 you can get it at 80-20.com its ok stuff if you dont have a welder, its like an erector set but more expencive. If you dont have a metal bandsaw i would suggest you buying good hack saw blades

The extrusion in the kit is Bosch 2020. It's 20mm x 20mm.

Check this site out.

The profile model is in the FirstCadLibrary.

Thanks Ed, I was just going to make that correction myself. The material was 20mm x 20mm so it's called 2020. We use a product called ITEM:

Our team has had terrible experiences using 80/20. Stay away! Rattles loose, impossible to keep together. YOu end up drilling through it and putting a bolt anyways. Never-the-less, it seems the team will be using it this year... again. I told them they can't say I didn't warn them

8020 can be used effectivly for a variety of areas. It is nice being able to bolt into just about any area of it. However, I could see how trying to build a chassis around it could be a bit of a nuisance.

171 uses the kitbot frame with spurts of aluminum square tubing and 20mmx20mm item. It seems to work out just fine.

I would suggest you check your assembly and fastening methods if you are having problems with parts coming apart. We used nothing but 2020 last year and made through Atlanta with no problems. The chassis was the most dependable part of the robot and it took some major hits.

We have used the KOP frame the last 3 seasons. The only time we had a problem with it was when we used the star nuts that comes with it. Last season we used all nylocks and we didn't have a problem with any hardware lossening.

We also just mount up with some aluminum members to box up the frame and thats what we use. It is fast, easy and strong.

If weight isnt really an issue, nothing beats 8020, or any varation of those numbers. The quick bolt on and off slide on all 4 sides provides a place to make quick changes on the robot when needed. IF you use 8020 buy tons of "drop in" nuts, if you dont the slide in nuts will provide too many headaches to count.
