    Anybody Using Rhino 8?

    I suppose that says it all. I'm looking for reactions, positive or negative, things to look for or look out for - whatever. About this time last year I started thinking it was time to upgrade from ver 5 to 7 and then saw that 8 was going to be released Real Soon Now, so I decided to wait...

    Shop Vacuum Question

    I was going to call this a newbie question, but I'm not really a newbie. Somehow I missed learning anything about this shop vacuum related question. How do I clean out the hose on the vacuum? I have a 2" Ridgid vacuum with the pretty common 2" flexible hoses. I use both water and oil on my...

    Can We Talk CAM Programs?

    I'm getting to really hate my CAM program, DeskProto. I bought version 5.0 years ago and have been using it ever since. Earlier this year, I saw they had a free version of the SW available for hobbyists; currently version 7. The thing is, either the one I bought or the reduced feature free...

    Shop Vac Question

    The inescapable cleanup from the milling machine either ends up in the shop vac bag, in the case of steel chips, but I sweep aluminum chips up with a small dust pan and save them in bucket, believing that someday I'll melt them down and cast aluminum. Monday, while I was sweeping up a few...

    Sudden Problems With my Printer

    I have a Creality Ender 3V2 that I've been learning the ins and outs of printing on, and in the last few days, it has developed a problem I've never seen before. No filament sticks to the bed. In the last few days, I went to make a little tool to hold sand paper onto a crankshaft I'm...

    Another Rupnow 1 by 1

    Starting around the time I was first getting my Webster to run, Brian Rupnow started a build thread on a vertical 1" bore by 1" stroke engine he was designing. I watched it within interest because I was trying to decide what to build for my second engine. I spent a while looking at hit and...

    Printer Calibration

    I have a Creality Ender 3 V2 printer that I got around Christmas. This is my first 3D printer, and once I got the bed leveled, I started playing with making useful things. I find that it's not printing exactly the right size. I haven't printed a calibration cube, yet, but I tried printing a...

    How to Scale Up An Engine

    I'm looking for my next engine project, and I'm interested in a hit and miss. I like the water cooled PM Research Red Wing model, but I'm looking for something made from bar stock rather than castings. I have the drawings for David Kerzel's Horizontal Hit&Miss engine but it's a smaller...

    My Drill Chuck Keeps Falling Off

    This is the drill chuck I use on my big milling machine. The mill has an R8 taper (Grizzly G0704) and when I was setting up tooling for it, I bought a nice chuck from Little Machine Shop for it. The chuck has a JT33 taper and I bought an R8 to JT33 adapter - from LMS, I think. If it matters...

    LMS Sieg SC4 Popping My Ground Fault Interrupter

    Maybe this is a problem that I'm the only person in the world has seen but with millions of SIEG lathes out there, maybe someone has seen it. My big lathe is a Sieg SC4 bought as the Little Machine Shop 3540. I've been having issues with a ground fault interrupter in my shop popping for a...

    Splinters

    I've been working on a steel flywheel on my lathe and I'm noticing a problem I've never had while machining aluminum. Splinters. Maybe a better word is sharp chips. Small, sharp splinters that get under my skin without me noticing and then stick whenever I grab something. I'm not good at...

    Yet Another Webster Begins

    I spent entirely too long deciding what to build for my first IC engine and finally decided to go with the Webster while waiting for George Britnell to finish his plans for the Holt 75. Last weekend (11th/12th) was spent tracking down and ordering materials and I had it all by Friday. I...

    Can Anyone Identify This Engine?

    Back in 2015, on my only visit to Cabin Fever, I took a short video of this engine I saw. This is a four cylinder, straight four, that's fun to watch. Lots of moving bits. I'd like to try to run down plans for this but have no idea where to look.

    So I Have This Crazy Idea...

    I've built two engines so far, a compressed air-powered wobbler engine and a Flame Eater. I had lots of trouble getting the Flame Eater running, but it eventually did. While getting ready to start gathering metal for a Webster internal combustion engine, I started thinking that it's on the...

    Philip Duclos Fire Eater

    I don't envision this as a build thread, because I have so little to contribute, but I could use some help with questions as I muddle through my build of this engine, from "The Shop Wisdom of Philip Duclos". I'm going by the book, and now making the second part, which is the cylinder. After...
