Recommendation for V-Carving Marble

I am planning to make a wall clock face with marble inlays and want to v-carve the hour numbers into the marble. I have never tried that but I will make sure to suck up the stone dust with a shopvac nozzle closely (don't think my dust collector will be sufficient and I don't want to mess it up). The...

Re: ROUGHING TOOL PATH

I use 75% stepover on roughing passes. I also try for the most depth of pass as possible. I push for the highest chipload I can get away with. This is how I reduce rough cutting time. It is after all just hogging out material. I never thought about going that high 75% ! Thank you! Why not it’s the ...

What a Project G. !! :) Must have been a few modelling challenges/ a few fixturing challenges as well! Love your twin keel shapes:) I ...

Re: The $1000 Sailboat

Continued... I did not want to go for typical daggerboards since awkward to attach to an inflatable so I decided to go for mini-keels to provide the required lateral drag. The keels were cut like the rudders with 2-sided molding tool paths for better hydrodynamic shape: IMG_2132.JPG The keel base wa...

The rudders are self releasing due to the need to beach the boat:

The $1000 Sailboat

As you may see from previous project posts, I am not so much in the decorative and artsy stuff but rather prefer unique utilitarian, technical and practical CNC projects. So here is my latest effort if you want to indulge in a few posts with pictures and the explanation. Background: I used to have a...

Re: inlaid golf ball

Since you can not see what is below the golf ball, why not cut a cylindrical pocket? Should not make a difference visually.
Maybe a tad undersized and you can squeeze the ball in without glue.

Re: Anyone make a homemade Holddown that adjusts to tighten from the side?

I made a flat clamping vise for my little mobile CNC, see video below. It consists of 2 sturdy plywood bars that are closed by 2 metal Harborfreight clamps and which are held town with 4 carriage bolts and knurled nuts onto the t-slot table. The cutout for the clamp rods is tapered so that the rods ...

Re: CAN'T INPUT A THREAD LENGTH

It has to do with the fact that the software only calculates increments of half thread loops. If you choose top-to-bottom, the thread start will be right at the surface with a flat loop making a nice chamfer and then go down in the mentioned half-circle increments so that you don't exceed the max de...

Re: How come my 1/2” end mill got warm doing this?

When you say "warm" what does that mean exactly. While I agree with the previous post's recommendations, I guess for the bit getting a little warm is normal, i.e. warm to touch. However, if that means it is getting really hot or even burns, well then it is surely too warm.

Re: Allowance Minder

It's interesting that in the image the "-4mm" allowance examples for the inside and outside profiles do not "kiss" the cross-hatch lines as one might expect them to (as they do in the no allowance version). That is, if they were cut using a 4mm cutter. You are right. But I used a downcut 1/8" bit. ...

Allowance Minder

At some point I found a picture or sketch here on the forum of what a positive or negative allowance means for various tool paths. That has been very helpful because this is not exactly intuitive. But at some point I lost the printout and where I had that from. So I made a real example of the variou...

Re: 10.5 and xp

Just another perspective.... My 12-year old machine control laptop gave up few months ago and I bought a $800 integrated desktop with 23" touch screen to run my machine controller (Planet-CNC with TNGV2 software). I do have a wireless MPG but sometimes it is convenient to push the machine controller...

Re: Thread Cutting Toolpath

I contacted Magnate about my old thread cutting bit and they could confirm in their system that I bought their number 796 thread cutting bit in 2015. And I bought a brand new one last week. Low and behold, the two are not identical. Magnate guy mentioned that there may have been a design change with...
