No experience. I choked at the price but bought a 4-inch Kurt from KBC years ago and it has worked well. At 65 pounds or so I find it very difficult to move a 6-inch vise on/off my mill table. Someone mentioned half-price sales of Kurt seconds. How do I learn of the sales. I don't see anything...

I believe that you are in Canada. KBC Tools is having a sale on Kurt stuff this week. Not cheap but 30% off their usual prices.

I assume that you are using a CNC mill for your work. If so, an effective approach is to probe the material surface at various points and apply the necessary correction to your gcode to cut a uniform depth beneath the surface. See for an extreme example of engraving on a non-flat surface.

I would first remove the spindle from the headstock and inspect the conical front bearing and rear bearing before making any plans.

Why not just measure your die and fabricate the holder appropriately?

Another advantage of using collets is that you typically lose less Z-room with a collet than with a drill chuck. I almost exclusively use collets for drills on my CNC.

I believe that you can do waterline finishing in MeshCAM. Isn't that about the same F360 Scallop? Or have I completely missed the point?

STL may be acceptable for some 3d stuff but importing DXF is essential for the things that I do. I have barely looked at MeshCAM but it appears to be able to import DXF. I currently use Vectric VCarve and it imports DXF.

I do mostly 2.5d projects rather than 3d so efficient metal removal is important to me. Other than F360, do any of these somewhat affordable CAM products support adaptive (constant engagement) clearing?

Of course! I completely forgot about the small clearance between the cams and the housing. My stupidity since I've actually already made the cams and the cam housing but had not yet drilled the holes for the push rods. I understand that the air pressure is on the side away from the seat and the...

Thanks for the ball location information; I completely missed it. How are the CAM follower balls attached to the rod plungers? For that matter the drawings don't appear to show how the rod plungers attach to the rods. On a different area, are the intake/exhaust balls pressed into their seats...

I have started a build of a Liney Halo and have a few questions now and probably many more later. There was a build thread here in 2009 but I find nothing since then. There are several YouTube videos of running engines. The Liney website appears defunct but there is a copy of the plans at...

A bearing race makes a substitute that is probably more than sufficiently accurate for home use.

Thanks for the link to the Onshape app store. Most of the products listed assume that you have a CAM package and just need to link it to Onshape. The only actual CAM product listed appears to be VisualCAMc for $99/month. As a hobbyist that is far out of my price range. I keep hoping...

Onshape is interesting but my ultimate goal is to generate gcode to control my Tormach CNC to make 2.5D and 3D pieces. Mecsoft offers a free CAM for Onshape that seems somewhat limited. Is there any CAM, hopefully free, that works with Onshape and will let me generate HSM toolpaths, peck...
