Dual Indicator Holder for Lathe AXA Toolpost - Version02

prusaprinters

<p>This is an indicator holder for use on a lathe with and AXA toolpost. As the title indicates, this is one of several versions so pick the one you like - or make your own improved version!</p> <p>Similar holders have been made by others before, but I was not able to find an existing 3D print for two indicators so I made my own.</p> <p>The two indicators I used for it are typically advertised as:</p> <p>2pc SMALL FACE 1.5" RANGE 0-0.25 DIAL INDICATORS 0.001"</p> <p>(about two for US$35 when I bought them around March 2020).</p> <p>As the name indicates, this works with two indicators with the idea that, depending on which face of the tool-post you use you will have an indicator in the correct position for either the side or the face of your work-piece.</p> <p>This version was an attempt to improve on Version01; it requires the AXA tool-post to be used at an angle, which may or may not be a problem depending on your work-piece. It's main disadvantage is that in the side indication position there is no front clearance so it can only be used at the need of work-pieces. On the other hand there is maximum room for large diameter work-pieces. I was not particularly happy with this version, but I am publishing it as others may find it useful, or it may provide ideas for further improvement (see my Version03!).</p> <p>Note that the holder does not have a height-setting stop - really not needed for this application.</p> <p>The OnShape 3D CAD file for this is here :</p> <p><a href="https://cad.onshape.com/documents/6ff0d36da3e37b30140aecce/w/3fc9ca902a5ab67f5c0a7aac/e/cb36e98114aed3d50d741a47">https://cad.onshape.com/documents/6ff0d36da3e37b30140aecce/w/3fc9ca902a5ab67f5c0a7aac/e/cb36e98114aed3d50d741a47</a></p> <h3>Print instructions</h3><p>Print in PLA using the 3mf file provided; otherwise :</p> <ul> <li>perimeters = 4</li> <li>infill 25% rectilinear</li> </ul> <p>These settings might be a bit of overkill, but I wanted to leave "meat" for threading, as well as some solidity overall.</p> <p>The mounting holes for the indicators needed to be tapped for threads after printing (1/4"- 20 or M6x1). I used 1/2" (13mm) long truss head screws (kind of a round head screw with a very wide head).</p>
