Building A GTWR Inspired Slow Speed Diamond Grinder for Carbide Scrapers
So I always wish that I knew the parameters that affect a DIY build before I begin to attempt it, like "what makes the most difference?" or "What parts do I have to really care about and what parts can I afford to fudge?"
Well with that in mind, I decided to make these videos the way I wish I could have 'em, in the hopes that they'll help others.
So in this video I go over the parameters of what makes a good DIY slow speed diamond grinder, or diamond lap. Using some cheap lappidary/polishing diamond wheels and a windscreen wiper motor, I was able to make a little tool that really helps sharpen tungsten carbide lathe tools & even carbide sandvik scraper blades.

Home Made Tools! - DIY Boring Head
Просмотров 9 тыс.Год назад
Time for another great intermediate machinist's project as I make a my own boring head for the home shop. These aren't incredibly hard to make, but they're definitely worth while and I had great fun thinking through all the challenges that needed to be overcome, especially with regards to fixturing and indicating in features. The boring head has a 20mm straight shank with a 50mm diameter body, ...
DIY Slitting Saw Arbor
Просмотров 10 тыс.Год назад
Today we cross off a home-made slitting saw arbor off of my very long list of tools I've always wanted to make. So recently picked up an import cobalt 80mm slitting saw. It has a 22mm internal bore which is pretty uncommon, but allows me lots of room to make quite a beefy low-profile slitting saw arbor. By recessing the head of an M8 caphead screw into the stub-arbour a lot of space can be saved.

It's finally time to make some cast iron chips on the DIY Vice build! In this episode we start work on the main body casting Getting castings ready for machining them can be quite a task in itself. In this episode we cover rough prep of the castings, basic squaring up of the surfaces to be machined with some basic hand scraping and finally the process of machining the top and bottom surfaces. I...
Home Built Vise Part 3: Making A Core Box for the Castings

Ever wondered what those holes in the side of old Kurt vises were for? Well so did I, and turns out they're not for weight saving or clamping, but rather a nifty way that allows them to be cast more efficiently using sand cores. In this episode we finish off the casting patterns by making a mould that will allow us to make such a core using resin bonded sand. At first I tried making it with fib...

DIY R8 Arbor Fly Cutter - New tool for the Vise Build

Scratching another tool off the list of things I need by machining a hefty fly cutter. These are another great example of tools that let you improve your skills while also adding to your arsenal. As single point cutters, they offer a lot of versatility and some great surface finishes but will need some consideration of feeds and speeds to take heavier cuts

  • @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.

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
