Thank you.
So the conduit you have has an Outside Diameter of 25mm? What size is it sold as (typically it is sold by inside diameter)?
If itās anything like here/Aus, conduit is sized by the OD. This discussion here indicates that the UK is likely the same:
The example given in method 2 mentions 25mm conduit with 1.5mm wall thickness giving 22mm ID and then using that as part of the formula for how full the conduit can be.
It looks like they also use the same weird mix of sizes for conduit, that we do. 20mm, 25mm, 32mm, 40mm, 50mm.
Thatās kinda nice because it allows mixing and matching between light duty, medium duty and heavy duty conduit and fittings because all the conduit is sized by OD and the fittings are sized by the ID to match the OD of the conduit, etc.

Here in Spain, you can find 32mm EMT easily. It cost about 14ā¬ for 3 meters long.

Awesome thank you!
Thatās super interesting. Thatās 32mm with a +0/-0.4mm tolerance range, so itās directly equivalent to 31.8mm tubing with a +/- 0.2mm tolerance, which means itās basically 1.25" tube.
Iām weirdly fascinated by this situation, even if itās probably a bit horrific for Ryan

@vicious1 If I was able to get hold of some 30mm tube, approx how much length might I need? I have a discount at a metal store and I might as well get everything I possibly might need - not trying to pin you down to anything, a bit of 30mm tube will always be useful even if nothing comes of your plans, but are we talking sheet width 4ā or maybe length 8ā?
On that same note, Iāve an itch to build a printer, would 4 or 5mm aluminium be best (or some other but whole mm only it seems) for the cncād flat parts on the v5? Everyone seems to be using 3/16" which is about 4.75mm so somewhere between what I have available to order.
Thanks for your help - donāt worry if you canāt/wonāt answer about the tube! Cheers

5mm, I have some flat sets to add to the shop soon if you do not want to cut your own.

Hi Ryan, would you consider making a 50mm/ 100mm tube version? Iāll happily rebuild my Lowrider V3 as a test machine if youād like (itās currently sized to cut a 4x8 sheet). I know 100mm will be massive and heavy but thatās kind of what Iām going for. Completely understand that it will be a test machine (I have 2 Chinese 4x8 machines that run my paid work, so this will just be for fun).
Iām thinking it would be like a rigid rider. Will mount the rails directly to a steel table and use steel side plates etc.
Iām based in South Africa and 100mm stainless and mild steel tube is very easily available. Itās used for car ports very often
Picture of my Lowrider V3 before it was finished. I unfortunately got some good deals on some second hand industrial machines so the lowrider got shelved. Iād much rather rebuild it that sell it off.
Sorry, there is another version in the works but it will not be that large.

In France, you can easily find those in āhome depotā-like stores:
Steel tubes, 2m/2.5m/3m lengthes: 16mm, 20mm, 25mm, 50mm
Note: We also got this strange octogonal shaped 40mm or 60mm tube that could be very interesting to directly bolt the struts onā¦

Those look weird and not really stable. 
Maybe a 10Ā¾ā dia. by 5/16ā wall tube would do? Iāve always been impressed by the stability of the oneway big gun.
