Re: Delrin drive nut (lee)
Lee,
I don't suppose you can do 12mm x 3mm RH trapezoidal thread Delrin nuts, can you? I've had two goes now at making a tap from bits of lead screw, but both have been too soft to cut the bits of molybdenum filled Nylon I have - they end up twisting.
I also need a couple of 300mm lengths of 20mm round rail, four carriages and four support brackets, as I've decided to change the design of my Z axis.

Hold on the delrin nuts for now although I may build a cnc to sell and will need them for that.
Email an invoice and ill pay with paypal.
Whats your paypal address mate? email it to me.
Re: Delrin drive nut (lee)

Hi sorry i ment to email you regarding that order, glad you recived them ok. Dont forget to run your new design past me, nothing like seeing your own kit put to use ;)
Re: Delrin drive nut (lee)
Just to be clarify ....these delrin drive nuts, would allow me to connect my M8 threaded rod (lead screw), to my stepper motor shaft (which I think is 6.35mm - from recollection).
Would these need any modd'ing or are they ready to rock?
If so, could you please quote me for 3 of them (inc delivery - UK based )
Re: Delrin drive nut (lee)
No they are used as nuts that run up and down your threaded rod, as the motor turns the threaded rod your axis table moves :).

Re: Delrin drive nut (lee)
Now I'm confused.
the post is entitled Delrin Drive nut (& it was always my interpretation that a drive nut is like the pic you've just posted above!), but in post 5 on this same thread (ie back on page ), has this photo...
http://img15.imageshack.us/img15/2282/mainaga.jpg
in that photo they look like couplers? (so the thread morphed a little & confused me!)
(original post - [ame="http://www.mycncuk.com/forums/showpost.php?p=2745&postcount=5"]MYCNCUK - View Single Post - Delrin drive nut (lee)[/ame] )
Do you still sell the pictured couplers as mentioned in the photo in 'post 5' of this thread for £7 each? (specifically M8 threaded rod to stepper shaft of 6.35mm diameter)
I reckon there's a good business op for someone to knock these couplers out at a reasonable 'pack of three' cost! (as all the couplers I've seen to date would mean if I bought them, it would result in more cost than the rest of my whole CNC build!)
Re: Delrin drive nut (lee)
The thread is about drive nuts, but in post 5 he says "I also have some of these" above the couplers photo.
