they are a great lathe, congrats!

Three more ways I've used for hex and or square holes, make a broach (standard type you push through), built up, and forged

His instagram says he's in Ontario. Quite the collection of stuff for a young guy .... including a 1928 Ford model A! Good for him.

I'll wait until its a a little less bleeding edge, but that's a pretty attractive machine. As a combination of amazing performance/speed, reliability, features, ease of use plus fantastic customer service, imo no one comes close to them. Good point Mike about X1C's hitting the market as...

That's not a deal. 179 on special at KBC. Well used, older model? $60 would seem about right. https://www.kbctools.ca/catsearch/1270/electronic-calipers

might be a good one for carbon fiber filament. I've not used it, bought our robotics team swears by it for higher strength prints

Is the real question then where to get a grinder and rattle can?

With that you could go straight to cast iron like our European buddy! Using it for the investment thought sounds challenging. The burn does a couple of things, dries the investment, burns out the pattern and gets the mold at the right temp for pouring. It's a long cycle, I usually go about 18...

good job, shouldn't be any need to pin it if you used loctite.

I shouldn't like to come across as if I know the best way, only that investment casting offers amazing possibilities and is, because I'm familiar with it, how I'd come at it. Stamping them may be best. I mistakenly thought the idea was to impress the pattern via rolls which seemed challenging...

If you don't know that lost wax investment casting was used, I wouldn't rule it out. It imo is your best chance given the volume you want. Get the right shore of silicon rubber, cast a mold, split it, send wax patterns to a jewelry caster. Arbutus, not bronze filament, but sending it out to...

That is pretty thin. I was curious what casting process because you can get quite thin sections with investment casting, I'm not sure though if you can over such a large surface. Maybe you've been down that road, but if not, what you can do with investment casting is quite different from other...

Drill and hole and file .... you might've been done by now :). I've made square broaches, but that takes a day's worth of chin scratching before you even start. silver solder (braze) a big hex shape on top that you can put a socket/wrench on. If your welding resembles a bunch of grapes...

Sometimes you do what you have to do, but imo there is only one right way:, turn it to the size you need. There's ways to get a decent shot a subthou accuracy. 10ths indicator on the cross slide, tight set up and super sharp HSS so you can creep up on it would be top of my list. Anything...

bit of a mystery isn't it? If pressed, the cross section looks substantial enough that it would take a lot of force, and likely expensive tooling. But there are lots of industrial processes I don't have a clue about lol. As to what to do? What casting process did you use? To me that seems...
