Shannon,

Great job. Stumbled across this thread the other day as i have been looking for something like this for my own chains along with a mini cyclone(Damn MDF dust clogs the filters) for my next couple of projects for my mahcine.

This is another one of these great posts that everyone will refere to and it will help every hobbyist make a professional looking machine cheaply and easily. Again its another step towards a completely homemade machine. Great work.

Looking forward to cutting my own chains for my machine soon. You've just saved me alot of money.

Thanks again.
Daniel

P.S Now if only someone can't make their own cheap CO2 laser. lol

I'm trying to see what keeps them locked together?

Hi Joe,

The outsides face each other so one link is comprised of two 'pin' side pieces facing inwards, the next link is comprised of two 'hole' side pieces facing outwards. When the top and bottom plates are attached they then hold the whole lot together.

I can put up some pics to make it clearer if you like?


Shannon.

i see how you have it, i was just curious what keeps the sides from sliding outwards other than a tight fit of the top and bottom pieces, but i tight fit should work fine.

Friction fit.

I am thinking with the acrylic they can be glued (carefully) with some sort of solvent, the chain in my previous photos is a really tight fit and shouldn't come apart under normal use. Saying that, I may still end up gluing it all together.

Thanks for sharing. Just found the thread after seeing the pics in the gallery a few days ago. Great job. I've been thinking about this for a while. Kudos on your work.

drafterman is on a distinguished road

I have been using some bonded hydraulic hose for a cable carrier. It is basically four 3/16" dia. hoses bonded together side by side. The hose is very flexible so it has a good bend radius, but it doesn't "walk" around as it rolls. I can pass my motor wires through one wire, limit switch wires through another, and 110V through yet another. I have about 10 months of use without any failure. You can find this in various diameters and numbers of "circuits". I crimped regular hydraulic fittings on the ends of the hoses and then used bulkhead fittings to attach them to my machine.

Big S, thanks for sharing your ideas. This looks like the way to go.

Does anyone have the file in Vcarve format? I loaded the posted dxf file into Vcarve but the parts were huge and I don't know how or what dimensions to make them. After I loaded the file into Vcarve, the individual parts might fit on a 4x8 sheet of plywood.

thanks,
Doug
