DIY Wood working machine

[indianvirus]

dear shulio
i used only one motor for this design but used two racks, synchronising two motors for one axis cud be pain, especially for someone like me who is low in electronics, so i found mechanical solution.

hey for your designs u can use one motor n one rack/screw, but u have to mount the rack/screw in centre of the gentry. i have built such a router with ball screw in centre. it is a heavy duty industrial router. check it out

I most wont to build this.

Is there a problem to use only one screw on the one side of the machine?

Can you post pictures of your last build based on this picture

i feel from your sketch that your gentry is very light in weight, in that case screw at one side should work. your design is somewhat similar to mine. there is no moving part under the table. i built a smaller machine with ball screw at one side. it worked fine. but it was very small machine 200x300mm. i m not sure for the same result on bigger tables

i suggest u use one screw at either end n try running the machine. keep provision for fitting another screw if needed in future. as for my design its just on paper right now. i have finished designing it on CAD. so no pics yet. i m gonna use two rack( one on each side) for long axis as mine has heavy gentry. i have already posted pic of my previous design.
