Maker of overly ambitious projects that include 3D Printing, Machining, CNC control, fabrication and automotive work.

A background in Engineering, combined with a bad habit of believing I can fix anything I set my mind to often leads me into some pretty strange projects. From building 3D printers, to home renovations to working on machinery and making my own tools, if you've found this channel, I'm pretty sure you're just as addicted as me to making the impossible possible.

Jak chcesz żeby miedź była miękka to po rozgrzaniu włóż ją w wodę. Z miedzią postępuje się odwrotnie jak że stalą.

That is the wrong way to fix abs the right way is to either get some pieces of abs Soak it in acetone or MEK Then take a dribble tool and make A Slight indention in the crack And brush on the ABS solution on your 2 pieces

Heated abs cracks easily. Use steel mesh from inside + abs slurry to cover (dissolve keyboard plastic in 646 solvent)

Nice video and presentation. I gave up the solid hollow cone idea based on the contact junction isn’t area contact but a line contact. When you have time do a blue ink test and you know what I mean. Also chips can trap in the expansion slot preventing it from closing and release of holder.

hi friend! Wich iron type did you use?
@devmeistersuperprecision4155
Wow! This is going to be interesting. The Kurt 675 was a classic. Got two a few years back and they were expensive. In places like South Africa I can see it as hard. Your going to need to check your draft angles. You also need to finish against swell. I been at it for years. I like sugar pine and mahogany. Durhams wood putty is an excellent filler. For cores, you need to use sand with water glass. WG is sodium silicate. You gas it with CO2 to make cores. I am going to enjoy this series.
@devmeistersuperprecision4155
Nice Job! This design is similar to one done by This Old Tony a while back. These heads are really useful. But….what is really cool is if someone would tackle a wohlehaupter head or the exotic and rate Tree taper boring head. I would do it but I am moving my shop and home and won’t be able to post machine videos for a while.

That's a pretty cool idea to use hard drives for the gyroscopic stabilization effect. I have to dampen out vibrations on this manually every time I bump it. But glad to hear from a fellow crazy inventor👍

Very nice build, I have a question for you regarding the carbide blades for your scraper, Is there a South African supplier for those, or did you need to import those? T.I.A.
@Mark_How
@Mark_How Год назад
Thanks, so I searched high and low for Carbide blanks, the most promising lead was the guys that do carbide tipped scrapers for conveyer belts for the mines. I eventually found a genuine Sandvik scraper from a guy on marketplace down in Durban, no idea where he got it, but it means they at least exist here. Other than that I've built 2 home made scrapers using square slab face mill inserts with no chip breaker geometry, but also not common anymore

I made my first one before I got a mill and I used endmills in the lathe collet chuck. Key held in a boring bar toolpost holder (designed it to have the same OD as the boring bar holder for that reason) and once it was centered up went to town on it with the end mill. Kinda tricky to square up the different sides without a flat reference but a construction level and machinist square did the trick well enough. I find that in machining there's many ways to skin the same theoretical cat, some easier than others but you gotta wee with the willy you got. Keep up the good work and cheers from Cleveland Ohio
