Z-axis with small 9mm carriages and linear rail (NSK)

Is this a bad idea? I have some 200mm long, 9mm wide linear guide rail from NSK, with matching 9mm carriages (two per rail). From the specs, it appears they have a dynamic load rating of 1490 N and 2150 N for static load for each carriage (photo attached). I have tried to find some comparisons to se...

Re: Construction Ideas

http://www.mcmaster.com/#99030a703/=yv5z0c 6ft of acme rod 3/8in with 1/2in per rotation. I don't understand why more people aren't using this at under $17 for a six foot piece. You wouldn't want to do six ft lengths due to whipping, but a 2-4ft section would probably work just fine. The cost is in ...

Re: Project Shapeoko HD

Just to add a small bit of info, those PBC Linear rails can be purchased at zoro tools as well. It looked like some of the prices were a bit cheaper. I forgot they were also at grainger, which does allow local pickup at their stores which can save a bit of money as well.

Thanks for the updates.

Re: Treatments for the Wasteboard?

I'm sure it varies by state and country, but I've found a lot of perfectly good "wasteboards" being thrown away in the garbage every week. Sometimes I see stacks of them. Old bookshelves, etc.

Re: Ideas for really large machines

It would, good idea. However, those seem really expensive. Are those parts really any different than shock/strut arm rods or gas pistons used in cars? Those are only around $20-30 for a pair on ebay, and I'm sure they have all different sizes to pick from. You'd just have to be careful to pick ones ...

Funny you mention that. I actually do have a ping pong table in my basement. I would not describe my particular one as "sturdy." :(

Re: Ideas for really large machines

Assuming we mount it on its side, so the gantry is vertical. Would we want the end plates on each end of the gantry to be in their original orientation ( perpendicular to the gantry) or would it be more stable to turn them sideways so they are parallel with the gantry? Obviously we'd have to rotate ...

Re: Ideas for really large machines

This might be too much of a deviation from the thread, and certainly harder for a 4x8 machine but I'm curious as to how hard it would be to produce a machine that can, easily (within reason), be torn apart and moved by one or two people. The large gantry should hold all four motors, which does reduc...

Re: Steel rail upgrade ideas

Thanks for the input. Here is an example of hard work screwing you. I was out digging and pulling out old stumps all day, only to come inside at 6pm to find the 30% off zoro tools coupon had expired at 4pm. You have to spend over $200, which wouldn't be hard with these rails. Oh well. Your measureme...

Re: Ideas for really large machines

I agree about needing something, but it would be a lot less heavy one way vs the other. Although, one could just have the "origin" point down and to the left, so it has nowhere to fall. Then there would only be the need for a rubber "stopper" or two, similar to what keeps doors from hitting the wall...
