Greetings; Attached is as far as I can get. This is the bottom face of a gaging block I am in the process of making for my CNC'd lathe. The next logical operation would be to mark 3 lines horizontally near the top of this, and plow a groove from side to side, with nominally 10mm wide faces whose vertex meets at a 90 degree included angle. This is to sit on the ways of the lathe. But everything is ghosted now. I also tried to make a sketch because it claimed I needed a sketch before I could plow a groove, so I made a sketch of the face in that menu. But now everything I need to proceed is ghosted. There will be a riser off the top rear edge, L shaped so that the leg of the ELL projects to the right over the lathes carriage, with another block glued to its front face, bolted to the top face of this base and positioned so as to hold a 2 pieces of dbl sided pcb to act as a probe contacts for forward facing cutting tools, and a swing into place but somewhat smaller, also with pcb contact faces to allow the auto-setting of such as boring bars whose cutting edges normally face backwards. What do I do to complete the current function so that I might be allowed to continue? Thanks. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Sorry. > I have no clue why ksnapshot didn't get the freecad's visible screen contents. I have started on another project, a cylinder with 'furniture'. I have the main cylinder drawn, sized & saved. Now I need to bore a small hole the whole 35mm through it on the central 'z' axis, but when I 'click' on where I want to anchor the center of that hole, the display jumps a long way off, or maybe even clears my work, and the only way to restore a view of my work is to stop FreeCad without a save, and restart freecad and reload my saved file. I actually need to setup to setup a 2nd cylinder hole, nominally 6.35mm in diameter through it crossways so it intersects the axis of the main cylinder, Then I need about a 5mm depression in one end face, about a 5mm radius, centered on the larger cylinders axis. And finally, a 1mm radius hole down the axis of the main cylinder, being drilled right through the center of the 6.35mm crossways hole and from one end to the other of the biggest cylinder. Since the smaller hole will go thru the 6.35mm hole crossways on its way through the main cylinder, my next step it appears should be the proper placement of this 6.35mm cylinders hole. So, how do I go about setting up this smaller, 6.35mm diameter crossways hole in the big cylinder, doing it in such a way that I can move this cylinder on the axis of the biggest cylinder in order to control the clearance of the end of the biggest cylinder to the next part when it is this medium cylinders location on the side of the biggest cylinder that actually controls the big cylinders location on its axis when its locked in place by this smaller cylinder pin through it? Once I get this figured out, the rest of it s/b a wash, rinse, repeat. And I will have actually made some progress on learning how to use freecad. Thank you very much your assistance.

Hi Gene, I suppose the best way would be to use the placement properties (in the Data tab) of the two cylinders to align them correctly, for example place them both at (0,0,0) That way you can draw them at random place and move them to the same point afterwards... Yorik |

But its been about a week, and I am close enough to done with the project that I am waiting on the screws to assemble it. A bag of 0-80's tap, drills & dies. If it works for 20 shots made from cold roll, then I order up some 01 tool steel & make one I can harden up for longer service, say 1000 rounds. BP 50 cal rifle.
