The various goings on in my workshop
Back in July of 2014 I bought a Boxford morse taper 2 chuck adapter. The Boxford lathe uses a 1 1/2″ 8TPI BSF thread, whereas my Mellor uses 1 1/4″ 9TPI BSF, the crests of which are smaller than the valleys of the Boxford thread. The first step was to machine off the existing threads…
Having sorted the design phase, it was time to start making the pieces of the power drawbar. I started on the mounting plate by cutting a piece of 16mm plate boring a 35mm hole and counter boring to 45mm to a depth of 8mm. Drilled 4 x 6.2mm holes and counter bored to 11mm to…
I decided a fair few years back that I wanted to make use of the Tormach TTS system on my Mini Mill. To that end I purchased a few items from Tormach whilst I was in the USA on holiday back in 2014, including the R8 TTS adapter collet (part #50568). At the time this was $23.75 (£15.00),…
I finally decided to start making all of the gears that were missing from my lathe change gear set. The full set is supposed to be something like: 20, 25, 30, 35, 38, 40, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 127. However I am going to make…
The next part of the articulating spacer was the brass wedges. First I cut a couple of pieces of bar stock then machined them to the correct width. then length. Next I drilled the holes for the stud. Drilled and tapped the holes in the end of the forked piece. Then setup for milling the…
This is the second part of the articulating spacer Here is the Fusion 360 drawing of the relevant part.This second piece is the rear plate that measures 10x100x16mm I did not take a full set of machining pictures for this one, as it is not a particularly complex part. The first operation was to square…
The articulating spacer for the SX2 is a design by Donald Bird that was posted on CNC Forums. The plans are all imperial, but this is a metric sized mill, so I converted all of the dimensions to metric and drew it up in Fusion 360.This first piece is the front mount plate that is…
Next up were one of the bearing mounts, 3 of these are required as well. Here is the model of the mount. First I cut about a 60mm piece from a bar of 2 1/2″ (63.5mm) x 3/8″ (9.25mm) flat bar, this originally came from ebay seller diamondengineeringsupplies at a cost of £14.76 for an…
I finally decided to start making the mechanical parts for my CNC conversion. This is a drawing showing various stages of axis mount evolution in exploded form. The ones nearest the middle are the ones that I am actually going to build, starting with the stepper mounts. I have decided to go with 60mm square…
Back in January 2014 I bought a Vertex 6″ rotary table that came complete with a set of dividing plates, now whilst these are very useful, and I have already used them to make a 40 tooth gear for my lathe, you need to keep your wits about you and ensure that you are not…
