Machining the Upper Mount for the Finder Scope
Let's make a Finder Scope! This video covers machining the upper piece of the altitude-azimuth mount. This is the third and final mill part to be completed by students in MACH 210 - the introductory course in machining and manufacturing at Laney College in Oakland, CA.
NOTE: This video is intended to be used in conjunction with a drawing packet and step-by-step manufacturing procedure. Follow along to get the most out of the content in the video! Download both documents here: laney.edu/machine_technology/projects/
Timestamps for each step in the manufacturing procedure:
00:00 - Introduction
11:15 - Step 2 - Side mill one end to clean.
12:11 - Step 3 - Side mill other end to 3.0” overall length. Use conventional, rather than climb, milling technique for roughing cuts.
12:50 - Step 4 - Scribe lines for vee. Granite surface plate is for layout and measurement only! It is not for storage or benchwork and must be kept clean!
16:22 - Step 5 - Mill one vee surface using scribed lines as reference.
19:40 - Step 6 - Mill other vee surface using scribed lines as reference. Verify depth of vee by measuring from bottom of part to top of ⌀.750” gage pin (should be 1.23”).
21:34 - Step 7 - Mill step surface .375” from bottom of part and 1.00” from right side of part.
23:56 - Step 8 - Mill other step surface .375” from bottom of part and center vee to 1.000” wide.
25:46 - Step 9 - Find left side of part in X and center of part in Y axis.
26:25 - Step 10 - Spot hole at 2.38” from left side of part.
26:29 - Step 11 - Drill ⌀.188” hole.
26:36 - Step 12 - Counterbore ⌀.32” hole .13” deep.
27:07 - Step 13 - Spot hole at 1.500” from left side of part and center of part in Y axis.
27:52 - Step 14 - Drill ⌀.281” hole.
28:01 - Step 15 - Counterbore ⌀.41” hole .25” deep.
29:05 - Step 16 - Find center of part in X and Y axes.
30:45 - Step 17 - Spot four holes for #6-32 UNC 2B threads.
31:00 - Step 18 - Drill four ⌀.107” holes for #6-32 UNC 2B threads.
31:54 - Step 19 - Countersink four holes for #6-32 UNC 2B threads.
32:42 - Step 20 - Tap four holes for #6-32 UNC 2B threads minimum .3” deep. Be very careful not to overtorque the delicate tap and break it!
NOTE: Mentioned, but not shown is Step 1 - Cut a piece of .75” X 1.25” 6061-T6 aluminum alloy rectangular bar to a length of 3.13” on bandsaw.
More about this project: The Finder Scope is a low magnification refractor telescope with an integrated altitude-azimuth mount. It is intended to aid in finding objects of interest in the night sky when using a larger, higher magnification reflector telescope which will be the capstone project in the machine technology course sequence. This is the student project in MACH 210. The videos cover step-by-step procedures for manufacturing each part of the assembly. Follow along and make your own! Or come take my class and we'll make one together :)
A note about sharing: If you are a shop teacher looking for curriculum for your own classes, feel free to adopt and adapt whatever you see here for your own purposes. Please, do credit me and Laney College if you do so.
A word about pedagogy: The parts, as well as the manufacturing procedures, in this project were designed primarily as learning opportunities for first semester students in a structured machining program. There were many difficult decisions we had to make about what to cover and how to best go about presenting the content so these beginning students could complete the projects in a limited time.

    Great content. Could hydrodynamic bearings (air or oil) potentially be used in micro gas jet turbines? Additionally, could they work with concentric shafts such as in two and three spool jet engine designs (eg RR Trent series)?

    1700 degrees? F " ! ? k. At least carbonettes dont burn or melt at that? I am puzzled how to make a furnace or stove that can hold the temperature and contain a four foot strip of rail. I have electricity, gas, (natural and propane) and wood fire. Aside from that this tutorial type video is the ducks nuts. Excellent! So vital to solve the question how to harden. Thank you, gentlemen.

    This video really moves along for us beginners, and assumes (fairly) that we can follow the rapid-fire tempo of the presentation (assuming we've been paying attention, and with the a few pause-and-repeat cycles). Not the easiest approach, but who does their best when it's easy? I'm impressed by the quality and detail of the information.
