    They look very similar to these (which I'm planning to buy): Aliexpress.com Ball Nut Housing.

    If anything I'd say they are lower profile than the one you've drawn up. The bottom bolt holes are in slightly different places but I'd be surprised if that was critical.

    Looks like that's for a RM1605 ballnut, but your mounting holes for the nut don't match? The RM1605 holes are on 45 degree spacing and they're 5.5mm diameter holes so you'll struggle to get M6 through them!

    And this is why I always insist the measurements on the drawings are taken from actual parts rather than Spec sheets taken from the Net.!!
    So easy to assume they will be like the drawings only for something completely different to turn up.!! . . . .Thou in this case I reckon it's an Err has most ballnuts of this size use 45 Deg spacing & M5 bolts.?

    Funnily enough I've taken home one of each item to measure with the vernier calipers ;)

    I've asked for a price for 4 off (I can't see anything apart from a 3 off listing) so will see what they, well the 1610 ones, come back with as they look exactly what I'm after!

    Just received some spiral flute taps from China so once I've welded up the frame (should have all the parts cut by the end of today as I did all the 50x50x4 box this morning and just have the 50x25 bed supports and bracing angles to cut at lunch!) and got some Ali cut for the gantry I can start drilling and tapping to my hearts content

    Tomorrow I'll add in the rest of the cross members and if I've got time (I doubt it in the 1/2hr I have available) the braces

    When putting the first angle brace on an upright I found out that in my haste to cut them I set the angle to 40° not 45°
    I would really like a couple of hours in one stint to go at it, I could then get it all tacked up and squared up ready for welding properly.

    That's looking really nice so far Neil. Not bad for a couple of 30min lunch breaks!

    Slightly off topic, but I found a video that I thought you might like. A neat way of cutting FR4 or CF without the nasty hazardous dust : CNC Fräsen GFK Ruderhörner - YouTube (make sure you watch the last 30 secs for neat bit of automation).

    Si.

    I've ordered these other ballnut housing and in total I bought 4 for about £26~
    just purchase but don't pay and then say you want 4 or however many.

    I've been welding my frame up and now that I have gas it's going pretty well! though i wish i had as much space as you do!

    Cheers Si, happy with it so far just need to press on next week and get it finished.

    I'll have a problem cutting CF like that as my router is vertical and for the first little while will have a wood spoil board until I can afford an aluminium one. Then I'll be able to use coolant :)
