I have drawn up an AXA-4D like boring bar holder. Have been trying to buy one for 2-1/2 months, but Aloris seems to be always pushing out delivery for yet another week. They seem to have some weird production problems, which is sad for them. Since I made an OXA boring bar holder for my mini-lathe last summer, (out of 7075) thought I might attempt an AXA-4D out of 1144. This time, I decided to use FreeCAD to model it. Out of a sense of making the drawing roughly look like a finished part, though I would add the 1mm chamfers. I can chamfer the top face edges and the bottom face edges, but not the side edges. The chamfer simply fails. Get a pop up that states: Input error. Failed to create chamfer. No other information was given.
Resolution: Seems one needs to add all the chamfers at once. I didn't expect that.
Edit: This is necessary to do on a body. If your part consists of multiple bodies, then one needs to complete all chamfers on that body. Then one can independently work on the successive bodies.
Drew this up in about an hour last night, except for the chamfers. Have an import AXA-4 as a rough template. Dovetail isn't quite exact. Need to measure the fit of the AXA-4 on the tool post and measure carefully with dowel pins. Pretty pleased to be able to draw something like this. Almost all the parameters are in a spreadsheet, meaning it is very easy to adapt. (Need to add the other parameters, but was having some fun determining an algebraic expression!) It appears I can fit up to a 1" bar in the block. What you see is the block for a 3/4" bar. Basic block dimensions are 1.5" x 2" x 3".
Can't say how tickled I am to be able to do this!
