My attempt at a DIY water distro block

Have you thought about making it from 3 plates? you could have solid front and back plates, cut all the way through the middle plate. You could cut a thin gasket from laser rubber (rather than o-rings) that gets sandwiched between the plates or probably what I would do is just permanently chemically bond them (you have no real need to ever disassemble). You could finish the edges once bonded to make it almost like a single block. I'm sure it'd work and be pretty unique! The challenge would be to avoid getting any chemical bond on the clear water channel part - perhaps you could use a dissolvable masking tape that could be washed out afterwards.
I did a lot of thinking and some experiments last year. That was my end approach - two plates and a hollowed out middle piece. But using glue was messy, and still hard to get totally watertight. I tried specialist glues which were better but still didn't look right, stopped short of UV cure resin. At that point I decided it was a bit fiddly and complicated, and I'd be better spending time learning a new machine.

The gasket sheet is an interesting idea though, as is the dissolvable tape. Have you see it available before? I may pick up this project again for a build!

Still like to get a CNC router if I had the space though ;)

Defy - an attempt was made! lol... it was my first time trying to make one so learned a bit. Cheers though!


@Zeeflyboy You say you did that on a hobby machine, well that's even more impressive then. Do you mind me asking how much the machine cost and do you have a link to somewhere that sells it please?

If I remember correctly it came to around £2.5k delivered with some optional extras like the 4th axis and a vice or two... but I've had it around maybe 4 years or so now, and as I'm designing my own machine I haven't kept up with whether there are better options around these days, you may well be able to find better for the money now... or hang around somewhere like mycncuk.com and keep an eye on the classifieds to pick up a probably significantly better used machine. With those caveats mentioned I got it from omioCNC in china.

I have done a few upgrades such as re-wiring the box in a less lethal manner and with shielded cables (machine didn't come grounded as they are worried about noise on the usb line, but I'm pretty keen on not killing myself), adding a high pressure air and misting coolant setup (a must have if you plan on doing much work in aluminium) switching to a different control board that uses ethernet instead of USB which is more sensible, and also changed out the steppers to closed loop ones although there's nothing really wrong with the stock ones. I added a closed loop water cooling system for the spindle (something guys here should be good at lol) and made some improvements to the bed.

Ultimately it's fairly cheap and cheerful and has some glaring design flaws but what was certainly a rarity back then at least was that it comes with proper linear rails which is vital for getting good results in anything harder than cheese. It's a light duty slightly honky wonky chinesium machine still but if you learn to work around it, which can take some time, you can get it to churn out some nice stuff. The advanced machining strategies available in fusion really really work well for it with a bit of tweaking, and I've had some stellar results in aluminium - here's the Z-axis I made for the new machine for example, all made on my current CNC (cutting the aluminium plates), lathe (shafts and pulleys), 3D printer (seals and plugs) and the anodising rig in the garage (oh and etched with the wife's laser!).

Hobby, cheap and cheerful maybe... But it's a lot more than the £260 3040 CNCs I've been eyeing up!

TBF with my girlfriend's laser we opted to skip the £400 eBay models and get a UK fettled one for 3k. Much less faff. But a CNC is much more of a toy for me and less of a tool for her business.

Right so I got chance to finish it off... one thing I'd do differently is I'd use a more opaque resin fill, because this one is clear enough that you can sort of see the sides of the letters which gives it a slight outline effect when viewed off angle. It's not a big deal but just nitpicking.

To minimise the effect without having to re-do everything I decided to thin down the letting to just 1mm by milling out a bit more from the back:

installed small RGB led strip I stole from a pump cover. Might change these out to just a straight 12v warm white led strip but we'll see.

Next up to the laser to switch things up (much quicker and less messy than the CNC for cutting these sort of things), need to cut out a light diffuser. I used frosted acrylic and put some light grey vinyl over the top (after cutting - don't cut vinyl in a laser!!!!)

And here's a pic of it backlit... very hard to capture well, the writing is a much deeper orange and the walnut a darker colour than the camera wants to admit (much more like the pics above). I might have to try to take a couple in daylight tomorrow and see if that works better.
