  • Mars-red - will you be posting the build thread in this subforum? I may looking forward to seeing the thread and the video. I already get notified when you post a video. Hopefully, between the two, I won't miss it.

        Richard, maybe you already saw but I did start a build thread for this - currently there are only links to my submission and entry videos in the thread. I am working on a detailed build writeup to go into the thread, though. And a video series going into the details of the build is in the works but won't be done right away.

          • Stephen dexter - It would be great to find reasonably priced Tripan parts. I have a 011 and a 111, but most of my holders are for the 011.

              • My humble selection

                Hi,
                I have just joined this forum and I have really enjoyed looking through other peoples projects on this thread. So much good work! I would like to humbly submit some of my projects. Most are shop made tools, some more ambitious than others. Some are highly successful, others are the best that I could do with the materials I had. I would really like to be able to make iron castings. Maybe one day I will summon the courage to recreate the sort of temperatures you find at the surface of the sun but until then it will have to be aluminium.
                Below is a poor man's spin indexer. It has a cast aluminium body and an integral three jaw chuck. The index ring has a row of 36 holes and a second row of 40 holes. I can get a fairly good range of divisions with those but of course you can machine one off specials if you really want prime numbers. I do have a regular indexing head but it is not as robust as this machine.



                This is a cross drilling adaptor that I made for my lathe. I saw the idea originally in the Model Engineer magazine. The aluminium casting was line bored while bolted to the compound slide so it will be accurately aligned with the axis of the lathe. The drill is an old AEG two speed drill with a metal gear housing which I found was important since some of the modern drills with plastic bodies are not rigid enough. It's great for drilling cross holes and it means that you don't need to remove the work from the lathe if there are any further operations to be done.


                This one is a shop built spot welder based on a microwave oven transformer. It is a loose replica of an Aston Portable Spot Welder and it runs at around 2.5 volts and I think at around 1000 amps. The front end is all aluminium castings and it has a digital weld duration timer, a cooling fan built in and all the parts a powder coated.

                    • Great work! I have a cross drilling attachment and use it way more than I would have expected. It's a really handy tool.

                      • 754,
                        The lathe is a Colchester Student MkII. I purchased it for AU$500 after it literally fell of a truck. I was having three lathes delivered to a school I was working at. The semi trailer arrived with the three lathes on the front of the trailer lined up side to side across the bed. The forklift operator nudged the one on the road side and the Colchester toppled off the other side onto the footpath. Luckily it fell onto the soft grass but it smashed the headstock guard, bent the chip tray and splash back and broke the handle off the cross slide but other than that it was surprisingly unscathed. It sat in a storage shed for 12 months so I offered to buy it on the basis that students would not be able to use it because of the broken headstock guard. I had a friend tig weld patches onto the smashed cast aluminium guard and hey presto it looked as good as new. The chip tray was more of a challenge. It was so hard that the same friend cut chunks out of it, hammered them flat on an anvil and welded it back together again. I repainted it, twice, the second time I did it properly after having the sheet metal parts sandblasted and I used two pack epoxy. Don't judge me on the colour. I like it and that's all that matters.
                        Regards,

                        • Wow, those are some very nice builds. Only one word currently comes to mind, SHOW-OFF.

                            • Spot welder resources

                              If anyone is interested in the Spot Welder build, I have put all the 2D drawings, the 3D model file for the complete welder and the 3D STL files for the casting patterns on Thingiverse at https://www.thingiverse.com/thing:2368142 No strings attached you can use as much or as little as you like.
                              There are also four videos on Youtube detailing how I model the 3D printed parts for casting patterns, some stuff about powder coating, assembly of the machined castings, etc etc.
                              The link for part 1 is below and you should be able to find the other three from there.
