Sieg SX2 7 Stiffening Bracket

- A bracket designed and made by Nigel Taylor to increase the stiffness of the Sieg SX2.7 mini mill. This increases the stiffness 1.5x. Check out more details here: www.glue-it.co... #minimill #sieg #milling #engineering
Thanks for your video ! That was something I was looking for my sx2.7. Your design is great and easy to process with the mill. Thanks a lot
Nice. A quantifiable improvement!
Yes, makes the SX2.7 a lovely small milling machine
Hello Nigel,
Nice work and explained well... Thank you...
Cheers.
Paul,,
Love the content. Came over from Artisan Makes. Subbed here.
Thank you. This bracket is one of the best modifications in terms of impact.
Great idea, great vid, I have the Sieg SX2P, I stiffened it up by sitting it on a piece of 20mm thick Bis80 with a welded length of 160mm C-channel up the spine, it worked brilliantly in making the little mill more rigid, I'm now looking to upgrade to a larger mill.
I had have been lusting after the SX3 for a few years, weight is a big issue for me, so I've recently been looking at the SX2.7L, your vid, has all but convinced me it's the way to go, there's only about $300 price difference here in Oz, but it's the 30-50kg in weight savings that has me almost convinced.
Thanks for the inbound sleepless nights of indecision;).
Scott.
p.s. subscribed, and binge watching your other vids:)
Hi Scott, cheers for comment and subscribing. The SX2.7 is a really good milling machine. Ample power and the table is big enough to leave a vice permanently at one end. More details on my page here:

Cheers, Nigel
What a good idea and nicely executed. I also have an SX2.7. I've sometimes seen people say the SX3 is more rigid and have wondered if I should have paid the extra. Perhaps this would be a way of addressing the difference in rigidity. I wonder what the SX3 would score in the same test.
I'm using the mill now and I have to say it has transformed it. It was good already, but now it's superb
@@editorglueitcom I'm glad to hear that you can actually experience the difference, instead of just knowing it's there. I have quite a bit on my "to do" list (including fitting a cheaper but bulkier DRO) but I'd love to try this when time allows. Thanks also for the details on glue-it. I will keep an eye out to see if you try the case/baseplate mod.
@@jamiegreentech2753 I reckon the sx2.7 column might be more rigid because the sx3 is open ended at the back supported by internal ribs and the extra weight.
@@HM-Projects Thanks, that's an interesting thought. It would be reassuring to think it might be the case. I'd still like to try Nigel's mod though, as it seems you can't have too much rigidity!
Have you thought about a 2" Riser? I'm contemplating doing it, I have some Forklift Tines that seem perfect for the Task once cut to Size and Surface Ground.
Where would this go?
@@editorglueitcom On the upright where it bolts to the Bed with the four Bolts.
Good idea, I think a smaller fillet might even work just to improve the connection
Hi Nigel, looks like a lot of work but I don't understand your stiffness graph is goes up from 0 to 0.03 in 6 stages but you have 2 stages for 0.02 and 0.01
Hi Fraser, this has had the most significant impact on vibration and noise levels. I would highly recommend. The stiffness measurements were done by loading the head of the machine with weights and measuring the deflection. The weights I have are a bit random and hence the data points are irregular. However, if you fit a straight line through this the gradient of the line is the static stiffness of the object. The comparison of the Amadeal to the Sieg mill and then the comparison of the Sieg mill with and without bracket have to be considered separately as they were made with different setups. However, each comparison as I've shown them is consistent. Best regards, Nigel
