Yup. 100 mm center height. Thanks for checking though.
The vertex one isn't to badly priced at under 60 quid thamk fully.

Do you need a geared stepper? If you can get enough resolution/torque/accuracy from direct drive then it will eliminate a possible source of backlash.
From the looks of it your main sources of backlash are worm to wheel and linear movement of the worm. I'm guessing linear movement of the worm is accounted for?
Don't be scared by the Arduino bit, it's really quite easy and loads of info out there

@eLuSiVeMiTe I think I have a set of dividing plates here I bought them about a month ago with a plan but have changed direction the Handel has been used but the pages have not should you diside you want a set at some time in the future i may sell them for a little less than I payed for them

Cheers Gaz. That's pretty much the way Intend to go.

No I dont in hindsight.
200 step motor as per Gaz link above. Didn't take In to account the extra resolution from the 90-1 reduction already in the table.
By linear you mean the worm spindle moving in and out of its bearing.
Barely any movement. May look at putting thrust bearings in if it becomes an issue. Just at the point I'd I nip it up anymore it binds.
The engage/disengage cam has a locking set screw and engagement depth is set by another. Now it's cleaned up and adjusted there's next to no backlash between the worm and spur and still runs freely.
Looking promising so far.
Arduino doesn't phase me. Can't be any worse than my rc quad copter. That was a pig to set up

Cheers for the offer. Il remember that if I feel the need for them.
Hopefully they won't be needed if I get this right the tailstock will be though. Do you have both? If so I'd take both as a lot.
NobI have the Handel plates and sector divider but if I was to part with it I would like to make a copy Handel first but don't have the tail stock

Other than the extra 2-1 reduction any other benifits to mounting this way rather than direct to spindle?
It's quite cumbersome especially if using the table vertically.

No worries. I'd probably never use the plates.
Must kurb my spending. It's mounting up atm with all the tooling I've been picking up.
Total for this project atm will be under £70 excluding the rt itself and ali to fab the motor mount.
Gonna go direct I think. Neater and less obstructive.

Belt drive probably simplifies the coupling, but if you can get a good quality coupling that will allow for the motor being off axis and misaligned to the axis then that would be my preferred route

Yes Definetly be looking for a flexible coupling.
Not sure which yet.
Keep seeing this style used.

Right now. Nope. Will in the future though.
It's a nice way of introducing myself to arduino and cnc in general and il gain a useful tool out of it.
Still have most of the bits required to power my table on the mill in the office. Another job I must crack on with.
Next year il be considering dro for both lathe and mill but plenty of work still to do on them both first.

My stepper motor came with a Lovejoy coupling on it, it was the X axis from a matchmaker,
so they must work OK; it was the same as things in the pic above with a red plastic bit.
I thought the plastic/rubber bit I had could have could have been harder.
My matsuura has sort of uj with sheet metal spider. if I remember rightly I haven't looked
at one for some time; it is definitely more positive.

Been racking my brains trying to remember what they were called. Cheers.

Yep I know the feeling about spending on the workshop but ha ho it might as well be in tools and equipment that passes time and you get enjoyment out of as in the bank at least in tools etc you have something to show for your money .I am allso just going to go down the direct route for the time being that's what I have been doing whilst cutting gears recently
