Firstly thank you for such a great video, I have watched this over and over again and showed to my staff also. The machines looks great and I wish I could also make something like this. As other comments on the workshop, I totally agree and its like being in a dreamland with all the toys to build everything. Thank yo so much for sharing your knowledge and I hope I can one day build a machine like this and run my controller on it.

Instead of milling the ways as at 3:28 if you don't have access to a large milling machine you could buy precision ground cast iron ( or mill/grind the cast iron pieces on their own on a smaller mill) set them up accurately on a surface plate with the mold and secure the mold so it doesn't move during casting. Depending on how big your casting will be and how thick your surface plate is will determine how you support the surface plate.

The white substance is a layer of silicone. It gives distance up to the epoxy after curing. Once the epoxy is cured we will shape and removes the silicone. The cast iron is now exposed about 5 mm of the cured epoxy. We use an ordinary cheap car wax called SONAX Hard WAX.

Granite stones and powder coming from different hardware stores and aquarium stores. Size 5mm to powder. The epoxy-HP-Te Epoxy system in Germany with hardener HP E30000GL in the ratio of 100: 30 by weight. Great base for CNC.

Hi, the rate epoxy to hardener is 100:30 by weight, but what is the ratio to the granite and that mixture?

Cast iron as it has good characteristics. It is "dead" and better to temperature changes might occur. It has a good combination of strenght and wear resistance with excellent surface finishes. The most importent, Noise and vibration damping.

Thank you for two very interesting build videos. I have watched both videos several times to learn and collect ideas. One question i have after seeing this first video, is why you put so much cast iron into the casting. It seems that both ways are resting on cast iron that goes more or less through the entire casting. One of the biggest benefits of epoxy granite, besides being lighter than iron and easier to cast, is its ability to dampen vibration; 10 times better that cast iron. When the ways of your mill is anchored to the large iron mass, does in not reintroduce the much poorer dampening abilities of iron? I have seen that you are under way on a new design, maybe this is one of the things you fix? Hope to see a future video of the new build. Thanks for taking the time to shed light on a very interesting subject.

Hi Jørgen, for the granite stones you used, did you have any specific ratios you used for the "Size 5mm to powder"? Or would random be sufficient? ( Great video btw. Very inspiring! )

What is the accuracy like? How did you align the linear rails and bolted them, what is the specific methods and process of it? 1:18 - What was the purpose of obtaining to cast iron? Was it because you needed specific dimensions which wasn't easily available for you from online or off the shelves from stores?

Hi, look like great machines. What did you coat your moulds with to make them release the bases? I noticed that you encased the inserts in a whitish substance that you later removed with the mould to make them stand proud, what was it? Would you mind discussing your aggregate mix? Interested to see part 2. Thanks, Ron

How are the linear slides clamped and alligned? I mean, the first one is simply bolted on the cast iron part with screw fastened onto the tapped iron? And if it is correct, the second linear slide how is it alligned? I'm seeing that you punch the second linear slide gently and checking with the dial indicator, however I didint understood'how this second rail is fastened onto the cast iron still being able to adjusted, and how is it permanently clamped down after the tramming procedure is completed.

Amazing video, I love it! Wondering about at 6:00 where the second rail is being aligned to the first. Does one simply choose one of the rails as the 'straight' reference, or use marking dye and a straight-edge to attempt to straighten it, or are there many options? Thank you for the video!

The machine you see 5:08 was built to produce large items without special accuracy. It is composed of aluminum profiles. The CNC milling else you see in the whole video is incredible accurate and stable if you compare with aluminum profiles.
