saundersmachineworks.com/products/universal-aluminum-fixture-tooling-plate?variant=39379872186470 I got the 20x6" size.

The low profile vise is from Saunders also. The bigger vise is a cheap grinding vise from amazon/ebay. They are all the same.

Hi, I just visited your channel. Nice work! IMO, your castings are large and strong. I don't believe filling them with epoxy granite (or anything else such as concrete) would cause any deformation. This is only my opinion, I don't know it as fact. I did not have any deformation issues on my filling. I also know several other channels took off-the-shelf hobby machines made of cast iron, and filled their column and base with epoxy granite, and had no reported issues.

@@nickp4793 okay thanks a lot for your request , do you know the proportion ? I heard it is like 90% rock 10% epoxy

@@ThomasLe_G If you stop the video at 1:03 min it has a paper with the ratios I used. I made about 5 different samples (shown in an earlier video) and settled on this one. It worked ok for me, but it was not super important it be strong, since I had a steel frame around the mixture. It looks like you are in a similar situation with your frame design.

⁠@@nickp4793okay yes thank you a lot ! I have done some calculs and I have almost the same pourcentage of epoxy resin who is 15%

It's my video. A Predator Revo shaft with a genuine Radial thread fit on this pin, but it was a bit loose.

You should never sand a carbon fiber shaft. Google is your friend, use it

@@440-fishermandrock8 I've straightened my shaft which is more important than being a sissy and scared to sand my equipment like a good little dog that listens to everything manufacturers tell us

Thanks!

Long pro taper.

Thanks man! The newer videos get a bit better. Making videos is harder than machining! ha ha.

I used about half a spool of PLA, or about $10 worth. The shaft is off-the-shelf, you can use whatever you want. The pin I used Radial and it was $15.

I have not, the whole thing got put on the back burner:( On episode 9 I filled the Taig mill column with this mixture. I might have fine tuned the ratios a hair, but I used the same ingredients. Its been a couple of years, and the mill is working great.

It's against my ceiling, which is 9 feet tall. The camera is an old Cannon DSLR with a 10-18mm zoom lens. The zoom is set to about 13mm. Unless your ceiling is over 16 feet tall, you need a wide angle lens like this.

"Sniper" tip, made by "Tiger" is a good one.

Thanks. The headstock is the stock ER16, yes. The motor is an aftermarket Consew CSM500, and the pulley and belt is aftermarket.

It's been great. I think I've had it since 2019 or 2020, I forget. Zero problems. I only use the mill for a project once a month or so though, so not heavy usage. I also bought a slower RPM higher torque version for my lathe, but haven't installed it yet. That is CSM3000 model number. The one on the mill is CSM1000.

No, just a tiny amount. Did not affect anything.

The predator was a 314-2 with a standard tip diameter of 12.75mm. The tip does not appreciably affect deflection. Lots of data to support that, go see Dr Dave's website for more info.

​@@nickp4793 I didn't mention deflection (mainly driven by shaft material) or english (tip size doesn't = more english). But I totally get why you might assume that's what I was thinking because of what was in the video. I wasn't clear... was just wondering if my eyes were right. From my view, wide tips seem to be more forgiving which can be interpreted as... it can somewhat hide small flaws or equally could be interpreted as... wide tips offer a little less sublety in control (again, no expert here, just my perception). I did decide to buy a Konllen AS series with an 11.5 tip. Beautifull cue, no warpage or defects a few seem to complain about. Looks stunning and feels great. Was just under $400. Basically $100 more for the Safflower Pear wood, abalone inlays, and the option for the 11.5 tip. Very pleased. Would love to have a Predator or any other quality name brand, but for someone who just plays for fun I simply bought the Konllen because I want to develop my feel/habits with a relatively decent cue and the price difference is significant. The Konllen wasn't exactly cheap, but in a range where I went for it. Think it was wise choice. Plays great. No complaints. Hard to imagine there can be a huge difference between much more expensive cues with respect to playability.

@@trevorwesterdahl6245 Yes, I agree. I think the Konlin is a great value for the money. You get a whole cue for a good price. I did like the shaft, and if my aim was not already fine tuned to the Predator characteristics, I would have probably kept it. Fast forward a couple years after I made this video, and I did eventually get the Predator Revo 12.4 shaft. I like it a lot, it plays to me exactly like the Predator 314-2, and I didn't have to make any aim adjustments to my game. Good luck with your game:)

@@nickp4793 Awesome! Your comment is why I bought the Konllen... once you adapt to a certain cue, seems like a lot of work to switch. I played enough with random bar cues to know I wanted consistency. Kept noticing big differences. Glad you got what you wanted and are pleased with it. Good luck with your game too!

I use a konllen over my predator with a revo shaft the konllen feels good in the hand and both tips I use are sniper tips the standard tip for cuetec. I get more power from my konllen cue and they are both 12.2

It's the 5019 model. (Same as 2019 except 5019 has ballscrews, while 2019 has V-thread leadscrews).

Hi, I bought mine without software. I'm going to replace all the electronics with Gecko G320 DC servo drives, and I'm going to put either LinuxCNC software on it or UCCNC. The first is free, the second is about 100 USD. Is there any chance you can send me some pictures of your machine? Does it have feet? How does it attach to a bench or a base? Thanks.

@@nickp4793 Hello, I can send you some photos, give me your email. My machine does not have feet, it is not fixed to any base, it is exactly the same as the one you show in the video.

@@RubenSanMartin95 Hi, yes that would be great. The reason I think something is missing on mine is there are SHCS on the bottom, and they are actually what would touch a workbench if the machine was placed on a workbench as-is. My email is onlinemailaccount@mac.com (I'll delete it from this comment once I receive). Thanks!

@@nickp4793 Done, I already sent the email. Thank you

@@RubenSanMartin95 Hi, thanks. I did not receive. Would you try again please? onlinemailaccount @ mac . com (I added spaces so I don't get spam, please delete the spaces when you send). Thanks!

It was too difficult for me to figure it out. Its a consew sewing machine servo motor that has a non-standard control compared to typical hobby cnc spindle motors.

It’s a Taig. Deepgroove is a reseller. It’s not his design.

Good points.

As he's already bought the material, maybe put lots (hundreds) of screws through the shell to hold the epoxy.

Yes it makes sense, thanks.

Btw, a few interesting research gate articles go into depth. It has been found that addition of 15% of flyash improves the compressive strength of polymer concrete upto 30%. Addition of 15% of Cast Iron powder of size less than 0.075micron has imparted around 14% increase in the damping ratio. To increase overall stiffness steel or even stainless steel powder could be used or embedding a steel structure within the epoxy. Its a very good idea to embed some sort of rigid structure and done properly you have a small machine that could have qualities of the larger industrial machines.

You can refer to the article through Google. “Synthetic granite composite for precision equipment structures”.

It was observed, through the ternary diagram made that the proportion of stone sizes tested that resulted in the best packing was: 55% coarse, 15% medium and 35% fine. This proportion resulted in greater densification reaching an apparent density of 1.75 g/cm³. Hence such proportion of stone size was chosen to make the synthetic granite composite focus of this work by ensuring the lowest resin consumption, in this way only 19% was added to the total mass of the stones resulting in a final material density of 2.1 g/cm³, denominated composition A. For the synthetic granite composite reinforced with carbon fibers manufacturing, the proportion between the granulations of stones was maintained. Only 0.5% by volume of carbon fibers of 2.5 mm in length was added to composition A, fiber-reinforced composition being referred to as composition B. Very interesting. Anyways don’t let the forums hold you back from discovering a better EG formula.

Thanks for the info. I'll look into metal particles. When I searched a year ago they seemed hard to find. I'll check out the West Systems site.

Nice! Actually they are still in a box:( After I made this video I purchased another Taig CNC that had ball screws (this one in the video had lead screws). It came with steppers and drivers pre-installed, and goes 200IPM with no problems. So I left it as is, and saved the JMC servos for a future project.
