CNC Router Build Part2 Finishing The Base And Prototyping The Spindle Cooling Scheme

[@C-M-E]

I like to think I'm pretty clever and resourceful, but that extrusion cooling loop was genius! I've seen and done fluid-routing through tubular frames and such, but never even considered extrusion for that purpose. Man, I'm impressed with this whole build!

[@unemployedredneckhillbilly2023]

Thanks. So far it has worked great and the extrusion seems to have enough mass and surface area for the spindle heat. Still haven't seen corrosion so it appears the aluminium safe antifreeze is working. Thanks for watching.

[@ukrainewarroom]

I like the idea of using the extrusion for a reservoir, nice!

[@unemployedredneckhillbilly2023]

Worked out good for my needs and no leaks so far. Thanks for watching.

[@dennismacwilliams196]

You have some of the best ideas' for a personal shop... I have never seen anyone with a shop that is even close to yours. So Awesome. !

[@unemployedredneckhillbilly2023]

Thanks. It's nice to have time to make things that work best for me. Thanks for watching.

[@刘小煜-g1l]

Genius idea, not only to save a lot of parts, aluminum profile is a good heat dissipation material.

[@unemployedredneckhillbilly2023]

Thanks. The extrusion alone weighs 35 pounds so it should work good. Have thermoelectric modules I can add to the coolant line if there's an issue under load later. Thanks for watching.

You've earned a sub and I'm only 2 vids deep in this build. You have a knack for making instructional videos. I enjoy the fact that I don't have to listen to "uhhhm's and Uhhh's" 2000 times through the whole thing. Cool build and great job!

[@unemployedredneckhillbilly2023]

Thanks. I am just sharing ideas about how I make things hoping to get others interested in trying new things. I like to try methods that are not standard and learn from them. Thanks for watching and subbing.

[@dgoddard]

@@unemployedredneckhillbilly2023 Same here. I've dabbled in everything from 3D printing to astrophotography to woodworking. I love learning and I have a short attention span. That also means I have a very light wallet. LOL

[@dangoras9152]

Awesome it never fails with you building something. Man ur something to watch keep it up brother.

[@unemployedredneckhillbilly2023]

Thanks. Always fun to try new things. Thanks for watching.

[@LogHouseFarm]

The bench looks great under all that stuff!

[@unemployedredneckhillbilly2023]

Didn't take long to bury it under parts and tools. Thanks for watching.

[@bufordtjustice4362]

If you havent already, look into UCCNC. It is supported and updated. I switched and now use their axbb ethernet controller. I really like it.

[@unemployedredneckhillbilly2023]

I am hoping to get rid of the pc. I like the masso but it's expensive so am thinking about taking a chance on one of the Chinese ones to start for $200. I own mach3 but don't like using the parallel port so that would all need updating. Thanks for watching.

[@richleviness4621]

Nice work, looks great.

[@unemployedredneckhillbilly2023]

Thanks for watching.

[@Peter-House-Jr]

You make some really nice stuff over a wide range of technologies - please keep up the good work. My only concern with using the Gantry extrusion for cooling would be the dimensional changes due to temperature change. How much longer does the gantry extrusion get when it is heated by 10 degrees? Rough calulation based on .022/degreeC over 1 meter - a uniform 10 degree C change in the extrusion temperature should make the extrusion longer by .22mm. The bigger problem might be if the temperature is hotter on the bottom half of the extrusion where the liquid is and causes the beam to bend - and the bend would be down in the middle - this could be reduced by keeping the tube more full to keep the aluminum a more uniform temperature.

[@unemployedredneckhillbilly2023]

Ran the spindle unloaded for over an hour and only saw a 5 deg f change. l am not worried because the room temp swings 3x that plus i have several thermo electric modules and extra 12v power to add if the swing spikes. I am not worried and that's why I told others not to try this until I have it worked out. Always problems to solve when trying unconventional methods. Thanks for watching.

[@ericroadking7564]

Man you do nice work!! Love the detail, looks ike a great design. Yaes time for getting the garden put to bed I just loaded u mine with seaweed and horse manure to sit over the winter.Thanks for sharing!!

[@unemployedredneckhillbilly2023]

Thanks. I was lucky to get 3 rainy days to work on machining parts for this. Garden cleanup is started and be moving firewood up soon. Thanks for watching.

[@graveurgraveur2691]

Great! Thanks for sharing.

[@unemployedredneckhillbilly2023]

Thanks for watching.

[@bigpat5819]

Enjoy all your vedios. Maybe you could make a video about all the types and sizes of channels and there connectors

[@unemployedredneckhillbilly2023]

8020 has a good book about that. Check out their website. Thanks for watching.

[@mishalea]

Quite handy!👍

[@unemployedredneckhillbilly2023]

Thanks for watching.

[@knotbynature454]

Awesome build so far 👍

[@unemployedredneckhillbilly2023]

Thanks. Hopefully I will finish it before the holidays. Thanks for watching

[@PhoKingLitMedia]

Love this idea! Can you send a link for the pump you used?

[@unemployedredneckhillbilly2023]

Its just a solar circulation pump amzn.to/48ujDqP with my shop being between 55 and 65 degrees year round the spindle water never gets warm on mine. I would add a radiator with fans if your shop gets hot

[@PhoKingLitMedia]

It geetts a little warm in the summer, but I think that would be more than adequate. Right now I'm just using a 5gal bucket. Im sure your setup will dissipate heat far better than my bucket lol. @@unemployedredneckhillbilly2023

[@AW-Services]

Enjoy watching all of your videos, such a talented nan with a wide knowledge of everything. What was your line of work and background? Will you be making a vacuum system with a pick up head next to the router, Keep up the great work

[@unemployedredneckhillbilly2023]

Thanks. I was a mechanical design engineer that was replaced by H1B Visa workers got mad and dropped out of the workforce. watching craigslist for affordable pumps. Thanks for watching

[@510BIGD]

Great video. Thanks. What's your source for the extruded rails.

[@unemployedredneckhillbilly2023]

Directly from 8020. They are expensive but mine were all very straight and flat. They cut them to the dimension you provide and ship fairly fast. Thanks for watching.

[@faspit95]

I love your ability to repurpose things. As far as using the extrusion as your heat sink I disagree. Good idea but the whole bar will expand and throw off your quality or worse twist and force extra pressure on your bearings. I don't like that added weight and if it sloshes around it can throw more stress on your hard parts and your electronics to start and stop and hold movements. A radiator would be lighter, more efficient and at worse case you would have to add a fan to it. Love your videos.

[@unemployedredneckhillbilly2023]

You will never know if you don't try. Barely any slopping around with the orientation and fill level and those extrusions use slotted t nuts for a reason. I have thermoelectric modules and a manifold to add if needed. Life is full of surprises. Thanks for watching.

[@giuliomilani907]

Beautiful job. Which type of pump do you use?

[@unemployedredneckhillbilly2023]

It's a brushless pump from a solar water system. I will put links once everything is tested and I am sure it will work properly. Thanks for watching.

[@SpencerScottFL]

Fairly new subscriber and really enjoying the build. When you design a 3D print like that bracket for example, what software do you design in. I just got a 3D printer and I'm learning all the ways to use it. Thanks. :)

Unemployed Redneck Hillbilly Creations Thank you!

[@scott8678]

Great video! I really enjoyed it. Where do you get your aluminum rails from? That seems to be the biggest cost for this project. Also, I noticed that all of your servos and/or steppers are belt driven. I am new to the CNC world and a little of confused for direct coupled vs belt driven axis, I am trying to learn something here. Why did you go with belt driven axis? Thanks,

[@unemployedredneckhillbilly2023]

8020 sells direct. To try and get in the torque curve, Servos are good for 5k rpm and steppers only good up to about 400 rpm before torque drops to be unusable. Look at the motor curve. Turns out the 5mm pitch on these screws is not optimal because they need 1000 rpm to hit 200 ipm and they start whipping at that speed. A 10 mm pitch sould work with the stepper direct coupled and get close to 200 ipm. Thanks for watching.

8020 aluminum company does sell gaskets. Those are proven gaskets.

[@unemployedredneckhillbilly2023]

So are mine now. I wanted coolant rated gaskets. Thanks for watching.
