9:58 thoughts My name is Chris, I am a 3D printing hobbyist from australia. I dont really specialise in anything specific, but 3D printed tools and tabletop accessories are some things youll probably seen quiet often. I do all my 3d printing on a Ender 3, which I highly recommend as a budget printer. Currently I only run 1 printer but I hope to expand that in the future. Recently acquired a photon 0 to do resin printing with. I like to share all my 3D printing ideas for free although I do plan to sell stuff in the future. Most of my projects will be mostly 3D printed with a few non printed components included, these can often be found on ebay. I actually use the cheapest filament I can get for all my projects, again I hope to change this in the future.
I’ve been watching Chris’ lathe builds for awhile. This concrete pour seems like a really useful idea. The lessons learned and advice given here are valuable insights into the practical aspects of this technique.
My main underlying curiosity is what happens when such a methodology is used to create automated single purpose machines.
Man, that’s cool! Concrete is a heck of a lot cheaper than epoxy granite resin and is perfectly suitable for a low-precision tool like this lathe.
I do hope that he finds a way to shield those bearings. You really don’t want metal chips or sawdust making its way in there. Any damage they sustain will cause runout, which will lead to increased chatter and parts that are out of spec. Plus, a matching pair of tapered roller bearings can be quite expensive!
EDIT: to be clear, I mean no disrespect when I say low-precision. Not every lathe needs to have slides and handwheels. I have a little Sherline lathe that I’ve used like this in the past (using gravers, not tools in a tool holder). It’s great to quickly turn something or to put nice decorative details on a part. Precision is possible with a lathe like this, but it requires fairly strenuous effort.
This is the ball vise fella, right?
Dude is a legend
Nice, but be sure to check out the Gingery lathe (and the whole series) before building - Gingery did a few things that would improve this if done. (and this does a few things that would improve what Gingery did)
Casting is much harder to access now in many urban settings. I wish I could but have no space for it where I live.
I said check out his book, not follow his patterns. There are some great ideas in this build, but also some things Gingery did better - and since Gingery explained why he did a lot of things like he did you will likely in turn be able to adapt the good ideas to this build. The way Gingery does the head stock is much better than this cast in place option for example. Combine the two and you will get better results.
BTW, if you are serious about building a lathe I’d recommend epoxy-granite not concrete or castings. Something more to research before building (or maybe just stop someplace and build - your choice)
Holy shit
