Hi,
I bought a KFLOP some years back, but never got around to use it.
I now have a project where I want to use the board, but I am unsure if the version of KFLOP I have is still a current...
Here is a nice video showing using epoxy grout for aligning the column to the base.

Before you spend too much time on this project, try to get a quotation for one of those motors. They are not cheap
Jacob
Voyager77, you are right. EPUSELF comes in pre-measured bins with the aggregates and the resin. The bin can be used to mix the polymer concrete in by just stirring with a mixer. The epoxy percentage...
If I remenber correct I think it was EURo 2.5 / kg delivered to Denmark. EPUSELF is good product and very easy to use. I have only had good results with it. And also the help and support from EPUCRET...
Hanermo,
I would be very interested in hearing more about your HS manufacturing capabilities. I am in Europe like you, Denmark. Would you share a little more information about a head stock in the...
Hi,
I am not answering your question fully here, but there is a rule of thumb that your thinnest wall should not be thinner than 5 times the biggest particle size you use. So if the biggest gravel...
Please ignore question. The screws are in the first video that inspired you to make your make your machine. But still very nice work :-)
Hi Phil,
Nice work!
I love these kinds of automated...
Hi Daniel,
Beautiful work :-)
I am still experimenting with getting the composition of aggregates right and scaling the mixing / vibrating process up to be able to cast parts with weight around...
Hi daniel,
Thanks for sharing your recipe for epoxy granite.
Your project is exactly why I find epoxy granite so interesting. With easy to find and cheap materials, relatively simple molds (and...
Hi Daniel,
Nice work.
Will you share with us, what aggregates you used and proportions of aggregates and epoxy?
Did you vibrate the mold after filling to get trapped air out?
What is the...
the4thseal, kkester1963: Thank you for your help. I talked to the supplier of a new epoxy I try, BASF. They confirmed the post curing heat treatment is a good idea as long as it is held under the...
LN-JET, PiotrCz: Thanks for the recommendations for epoxies. This is very helpful, but I think I need to brush up on my Polish. That datasheet did not make a lot of sense to me :-)
the4thseal: I...
Piotr,
Interesting experimentation. I am also experimenting with epoxy granite casting at the moment.
Will you share your mix?
What I have found is that the mixing is a bit of a problem,...

Al and undertehtire,
Thank you for your help. Guys like you make the forum a very valuable place.
Thanks
Jacob
Hi underthetire,
You are absolutly right, the diagram is of an Mori Seiki NVD. I included the diagram as a sketch of a two drive per axis system. The NVDs are extremely complex machines and I...
Hi Al,
Thanks you for your answer.
1. The Galil controller looks interesting. I have had a brief look at their website and they even have a local distributor here in Denmark. Have you had any...
Hi Mike,
Thanks for your reply.
I am actually surpriced there are more routes to go, but then I am totally new to servos.
Can you comment on which approch to chosse if I am build a mill for...
Hi,
I am researching concepts for a new mill design I am working on. On my travels on the internet, I have seen designs for large routers that used two stepper motors to drive the x-axis. One of...
Hi John,
I have followed your design threds and E/G test. Good work.
Looking forward to follow this build. Especially how to cast E/G for a base this size and how your are going to mount gantry...
Hi Alex,
Like you I am experimenting to find a good formulation and construction process for EG. I am no expert.
From my experimentation I think you could improve your formulation by having...
