As a German, I second that: _Almost_ any tool found anywhere has bottle-opening capabilities. And, depending on whos calipers/torque wrench/ratchet/...you just used to open your beer with, you are also liable to find out that _every single tool within reach_ also can be used to smack you on the head quite hard.

I used to be an automotive mechanic back when we still turned rotors and drums at the shop. We were always told to inspect for inclusions or defects after every pass. I probably turned thousands of rotors/drums over the years and never found any. So yeah, they're probably a great source of cast iron, especially if the part you need is smaller than the original dimension of the rotor.

For mounting weird stuff in the lathe, I have a sacrificial face plate. It's just 12mm thick aluminium plate cut to a 150mm circle, and permanently mounted on a 25mm mandrel which fits securely in the 3 jaw lathe chuck. So I can take it in/out of the chuck in a couple of seconds. Being "sacrificial" I just drill and tap anywhere on it to hold the weird gubbins as needed, and can even hold a counterweight etc. For most jobs it has enough tapped holes in it I can usually find a way to hold the gubbins with some of the existing holes and some washers or bits of junk used as washers. I'm sure you can imagine it. But that best bit is the mandrel lets me pull the whole thing in and out of the lathe in a couple of seconds, retaining concentric alignment in the 3 jaw. Very handy! 👍

G’Day Mark, loads to comment upon, so here we go. First, Danke Stefan! You must be one of the good guys. 👍 Next, crafty repair work there. I’d not have thought of bringing epoxy into it, myself, but it seems perfectly suitable in this application. 🤔 That’s a superb drill press you have. Wish I could find one… Love that stop motion! 😃 I suspect that Vienna imposes the same sidewalk rule that we see here: irrespective of the municipal ownership of the sidewalk itself, it’s the abutter’s duty to clear the sidewalk of snow. We have 24 hours to accomplish this. It is burdensome for some owners, but we muddle through.

@RotarySMP 7 ай бұрын

Hi Doric. That drill is lovely. Made in Vienna, so probably not common in New England. Thanks. I like doing the stop motion for small assemblies like that. Here if you dont clear the sidewalk, and someone slips, you are liable. At least if it is icy, you theoretically dont have to clear snow, but it will turn to ice. Lucky I only have 9m of sidewalk.

@loydsa 7 ай бұрын

An excellent video that obviously took a great deal of effort to put together! At one point I found myself thinking NO in my head as the epoxy was deployed, then once I had reigned in my inner engineer I realised that the solution I would have taken would have been far more work, and suitable for a Rolls Royce engine not a bandsaw blade guide 🙂

Also, if anyone is wondering why people would convert to Mach3 instead of Mach4 - the newer version isn't compatible with a lot of the older stuff, and the company, Newfangled Solutions, does quite a bit of gate keeping when it comes to developing for Mach4, and getting the SDK and development tools. I also see someone got themselves an RGB light for filming...

@RotarySMP 7 ай бұрын

Hi Alex, I have two RGB lights. One is a COB with a soft box, and the other a smaller LED panel. The main room is now has 4000K LED panels in the ceiling, so it works fine for filming Schuablin, DoAll, and general bench stuff. The garage is a mess of incandescent bulbs, old florescent tubes, etc. I am chipping away at it. The ring light on the Maho was a gift, but it has really cold light (must be 5500K LED's, probably with low CRI). and is a nightmare for color balancing the filming of milling operations. Sooner or later I need to redo it with some high CRI 4000K LEDs.

Nice video. I've always thought that Doall seemed to go out of their way to complicate many aspects of their bandsaws. From the guides to the transmissions. As complicated as the guide casting are, they still are not adjustable for different blade widths. You are giving new life and making things better tho. Grob saws are the same, different guides for each blade width. I made fully (1/8-1") adjustable guides for my Grob vert. saw.

I hate to be "that' old man. sometimes your music volume and choice overshadow your subject matter......and your subject matter is always excellent (or at least fun). nice video

Thanks for your feedback. Music choice is really challenging. I need it to drown out some machine whining, and cover up when there is no audio (slow motion), but for every compliment on it being great music their is an equal and opposite opinion.

Nice work! If you're going to be ripping metal parts on the doall, it might be worthwhile to fab a gravity/pulley based feed mechanism (and spring guides) to keep a light steady pressure on the part? pull the part with a magnet or a hook in a notch?

@RotarySMP 7 ай бұрын

My DoAll has that system built in. See the chains at the edge of the table... they connect to a counter weight which you raise with a foot pedal.

Pity you do not have high temp metal spraying equipment as this would have allowed a much simpler repair of the guide slots and potentially the bearing bores. I have repaired key seats like this many times. You were lucky machining over the thread inserts. Instant death of the cutter if the insert were to move. Don't ask how I know :)

@RotarySMP 7 ай бұрын

I didn't realise you can metal spray cast iron. I have only seen the process on Abom's channel. Nothing I will be able to tool up for.

@@RotarySMP eutectic have a have a hot and "cold" processes. both use specialised oxy - acetylene torches. The cold process is really only suitable for building up bearing journals and is useless for tensile stresses. The hot process is akin to brazing but uses a very fine powder to supply a self fluxing filler. Both systems require proprietary torches and powders and are crazy expensive and really only justifiable on high value or parts. I don't follow Abom but a quick search throws up SNS279 showing the hot process and it's applications.

Nice fix man, real thorough (too bad about the gear slip) . Mark, do you still use that fancy studio camera stand you built a few years ago? Curious for some reason.

@RotarySMP 7 ай бұрын

Yes Tim. All the time. It is soooooo much better for this type of work than a tripod. Even if my design was compromised by the need for a narrow base to get through narrow door, and the horrible uneven tiled floors, it is still a huge benefit to the workshop studio.

@@TimBielawa Thanks a lot Tim. If you don't need to get through narrow doors, make the base a bit wider. The tires on the cross beam bearing block are wearing out and getting a bit chunky, but they are cheap, and easy to replace.

Were you scrubbing the parts in the ultrasonic cleaner while it was running? If so, don't do that! If it can impart enough energy to blast dirt and grime off a surface, even its when inside another container, just imagine what it can do to your blood cells, bone and ligaments.

No that was during a pause between runs. I didn't put enough NaOH in the solution, so it was faster to loosen any heavy build ups with the brush.
