    Turning a hardened shaft

    Hi all, I'm making an arbor that needs to run in some needle bearings, and has a profile turned on one end. I have some hardened shaft of the proper size, and was wondering if there's any reason I couldn't cut it in my lathe with carbide tooling. Will I break something horribly? I've cut a...

    Power Wheels Cars

    Hi all, I've been gone a while, but I've been busy. I'm involved in the power racing series (PPPRS). We take kid-sized ride-on toys, re-build them, and race them (the goal being to have a good time more than win). It's been an excellent test of my fabricating skills, and now that the season...

    High Speed Video

    Hi all, When I got my camera, one of the things I liked about it was that it can shoot video at up to 1000 frames/sec. So of course, I film a lot in slow-motion. Today I was boring out some bearing mounts on my mill, and thought it would be fun to film it, so here it is...

    Long Work

    Hello all, It's been a while since I've been around here. Good to see you again. I've got a bit of a problem at the moment. I need to machine an axle. It's 36" long, keyed down the length, and threaded at the ends. I need it to be 30" long, which brings me to my problem. I have a 10x36 lathe...

    Centering Parts On A Rotary Table

    Hi all, I need to cut some radii on the ends of some stainless pieces, which means I get to use my new rotary table! Yay! The piece is 5" x 1" x 0.075". I need to cut a 0.5" radius on the ends, and there's no hole under the center. Any tips for getting the piece centered? I recall reading about...

    Rotary Table -- What Do I Need To Know?

    Hi all, As a present to myself I decided to get a 6" H/V Phase II rotary table. It's in the mail, and my ears are tuned to the frequency of the UPS truck. But that's beside the point. What do I need to know (or get/make)? I've used a rotary table once in my life, and it wasn't even my setup, so...

    YABH -- Yet Another Boring Head

    A little while ago I threatened to make a boring head out of cast iron, and now I'm finally getting around to it. Here we go! Part 1 -- http://tinyworkshop.org/tools/building-a-boring-head/ Part 2 -- http://tinyworkshop.org/tools/building-a-boring-head-part-2/

    Cast Iron Boring Head

    Hi all, One of the projects I'm going to tackle is building a boring head for my mill. I'm planning to use Steven Campbell's design. I can get cast iron in ~1.5" size cheaper and easier than mild steel. Would it be suitable for such a thing? My thought is that since machines are made from it...

    Interesting tool bit setter

    Here's a lathe bit height gauge I saw on ebay this morning. http://www.ebay.com/itm/Lathe-Tool-Centering-Gage-Bit-Height-Setting-Leveling-/260897080551?pt=LH_DefaultDomain_0&hash=item3cbead84e7 Looks like something that could be replicated fairly easily. A clever idea, certainly, but my question...

    Indicator Holder

    Hello all, I've been wanting a better indicator holder for my mill for a while. I have a cheap Indicol clone, and it's really just garbage. So I set out to make my own. The main inspiration for this build was when I found this little pivoting dovetail holder. It's a little grimy, but it had...

    My Bit Of Basement

    Hello all, It being Thanksgiving, I've been off school. My original plan was to hunker down and build a boring head, but I had no stock. I turned to any number of other projects, only to realize that I had no sock for any of those! So what to do? Clean. And since my shop was clean, I figured it...

    Cleaning Fine Pitch Threads

    Hi all, Today I cut a 96 tpi thread in some brass. As you can see, there's lots of gunk the got stuck in the threads after cutting them. I took great care in cutting them, and they're fairly fragile. What would be the beat way of cleaning them without damaging them?

    Milling the Atlas 10" compound

    I wanted to do some single point threading, but didn't have room to turn my QCTP on the compound. http://tinyworkshop.org/tools/modifying-the-lathe-compound/ So I made room. Problem solved!

    Atlas 10F Micrometer Stop

    I've been boring a lot of blind holes recently, and decided that I really need a carriage stop. I had a Tumico micrometer head lying around, so I can make a micrometer stop. I'm drawing it up beforehand, to hopefully minimize the amount of scrap I'll make. Here's the top. My atlas has a flat...

    Jacobs #100 Chuck

    If anyone is interested, I'm selling my #100 Armature chuck on eBay. Two came with my lathe, and I really have no need for them. If you're interested, here's the link. http://www.ebay.com/itm/Jacobs-100-Tailstock-Armature-Chuck-/170701174026?pt=BI_Tool_Work_Holding&hash=item27be95350a

    Dual Rocking Engine

    Hi all, My first engine build was a rocking engine. I'm not sure what it was about that thing, but the "blow over" piston really captivated me. I wanted more, and building another wouldn't satisfy that need. So I decided to build a dual rocking engine. And as though that wouldn't be enough of a...

    Hello From Chicago!

    Hello all! I've been reading these forums for quite some time and decided that there was no good reason for me not to be registered. So I did. I'm a high school student who's been interested in making things since I was five (or maybe earlier). I've been doing woodworking my whole life, and more...
