Ok guys just have a quick one for you all. I have some 8mm threaded rod at the moment which I will be using for the machine to drive the X Y and Z axis as I have had it given to me for free so why not use it for the time being. I came up with an idea for the leadscrew nuts and that was to take a large washer which has a hole so that the 8mm threaded rod can pass through and then epoxying a 8mm nut to it and then when this is dried and firm thread it onto the threaded rod and then glue another nut on the top but just tightening it so it takes out the backlash and believe it or not there is very little if no play in it at all. I have made 2 so far and have fitted it to the Z axis and the Y axis but have ran out of some epoxy to make one for the X axis. So my question is to you all is what are you guys using that is better than this and works without any problems ?? Also I would like to eventually upgrade to some Trapezoidal leadscrews maybe some 1/2 10 which seems the most popular leadscrew that everyone is using but again I am a bit green on this issue so any help would be great and also other than Marchant Dice where is the best place to order this and what would the cost per meter be ?? sorry for all the questions guys. Laz.
