oh man i was waiting to see what the final cut out looked like and it left me hangin!

Some guys cut with a blade but you cut with a bit. How were your edges? What was the final product?

[foampro]

Fairly clean cuts. I have custom bits made for cardboard. Took a while to figure out all the variables to make it so it made a good finished product. Here is a chair that we recently built. The parts were pulled off the router, glued together, boxed and shipped off. No other work was done to this piece.

Now thats cool...thats a "inside" piece right?(doesn't go outside). I bet it is pretty light but sturdy. good job

[knight_toolworks]

what are your bits? I have to cut cardboard where they need really clean edges and I have not found anything that can do it. though I have found using a 1/8" bit gives a cleaner cut then a 1/4" bit
one thing that would save you a bit of time is to choose the inside and outside cut and do it with one toolpath. just use profile cut outside and the inside is cut first then the outside.
I made a knife to cut cardboard so I get very clean cuts. but I have to turn it manually for straight connecting lines. but it makes perfect edges.

This is a tangentail cutter I made.

I don't know if shopbot supports a tangentail axis.
Thanks

I would like to do that but the cost and my skills are not up to it.

[donclifton]

Its really very simple. its a gear reducer turned on end and setup to do degree's. If shopbot supports tangentail axis you just set up that axis and it follows a tool path.

I know it can be done but I don't know if I could do it. I don't cut enough cardboard to justify the cost right now.

[foampro]

We had some custom bits made. It is a 3/8" 6 flute compression. We had to buy 6 of them to place the order. I would part with 3-4 if anyone is interested. For the amazingly low price of $165.00 per bit. BUT WAIT! There's more! I will ship them to you for free! Ya, they are pricey but we do a lot of custom cardboard products and needed a bit that would give us a super finished product without any cleaning up.

how long do they last? I found bits don't last a log time in cardboard.

I have a dumb question. How much does a 4x8 sheet of cardboard go for?
Must take quite a few to make some of your products.
They are cool though. Great idea.

Would anyone share their sources for sheet cardboard - thanks.

Sheets of corrugated cardboard are called corrugated "pads" by box companies...

Many people on this forum, including myself, by boxes and pads from a company called Uline. They have facilities all over the US and stock a very large selection of sizes, which are available in low min order quantities.

I'd also add that their customer service/delivery service is top notch. They're one of my favorite suppliers to deal with.

Here's the URL for their pad selection:

I agree with Russ that Uline customer service is very good. Just watch out for S&H. I used Uline for about 8 years, when I lived near Cincinnati, OH, for specialty items that I couldn't get locally and in many cases the S&H exceeded the product cost. If you live close to one of their distribution centers you can pick up your order but having it shipped is $$$$. Maybe it was because my orders weren't big enough to require freight type shipping but could be shipped via UPS and the cost was HIGH.

Since moving to the Northwest USA, I can't use them because on just about everything I've wanted to order, the S&H is more then the product. I've managed to find a local supplier where I can pick up cardboard type products at Will-Call.

If you happen to live in southwest OH (Dayton/Cincinnati) there is a company called Argrov Box Co. (http://www.argrov.com) that I used for several years and they have all kinds of stuff similar to Uline. I priced product through both Uline and Argrov since moving to the northwest and Argrov S&H is considerably less then Uline. I don't know why.

"If shopbot supports tangential axis you just set up that axis and it follows a tool path. "

There's a program in ShopBot Labs that does just that, from a PartWorks or PartWizard-generated toolpath.
