As I go through Algebra/Trig ("Pre-Calculus") at school, I am stumbling on a number of sample problems that could come in useful for our hobby. I have been re-learning all this stuff under a new light, trying to adapt what I'm learning to what we do in engine design and building. Would anyone...

I got my 4 jaw cleaned up (so i thought - until i turned on the lathe with it mounted. THEN it was clean.... nothing else in the rotation plane was, though) this weekend... and decided to give it a whirl. After a quick google on centering parts in a 4-jaw, I got pretty good results with my brass...

The last bit of my order from OnlineMetals arrived today, two 2-foot lengths of .063x.25" brass sheet. Looking at the edges, it seems obvious they used a shear to cut them. No big deal, but if that shear was not cutting all at the same time (instead cutting from one end to the other more like...

Decided that I had digressed too much from the original purpose of the 'taking the plunge' thread in Q/A forum, as I have now purchased the lathe and am in the process of cleaning it up. To everyone who answered my endless questions in that thread and PM's, I thank you greatly. I will...

Greetings all, The month of June in the United States is National Safety Month. While in my own line of work (and many of yours) and our mutual hobby dictate that we follow safe practices *Every* month, I would like to propose we all take a little extra time this month to step back and...

Going to be heading up to grizzly this holiday weekend (one of their four warehouses is about an hour drive) And it [u]was going to be just for looking around, but the more I think about it, the more I get the itch. I've fairly settled on the G0704 mill/drill with stand, as my first machine...

I've seen many references all over the web to the Eric Whittle V-8 plans, and am interested in playing with them in CAD as a new project (I find that I learn a lot just building things in CAD, since I have no workshop yet) Many more recent references to these plans suggest that they are freely...

Well, even safety glasses don't always protect you. My safety glasses for work have side shields, and a foam pad across the top designed to sit against the eyebrows to prevent debris from entering from above. I was drilling overhead, and the glasses slid down a little, letting several small...

I see quite a lot of references to the Sieg mills, X2 usually, and occasionally X3. So I loaded up sieg's site and found that their distributors are harbor freight, grizzly, etc.. I chose the x2 to try and find equivalent models at these distributors, and have found what LOOKS like them, but...

I'm looking at possible other projects, and poking around steam engines decided to try for an engine with a heavy steampunk look, probably steam driven as well, but I want to add smoke to make it run" dirtier" than the nice clean steam engines i've seen from you folks ;D Any suggestions for...

While at work drilling holes in a $150mln airplane (sure do hope those holes are in the right place...), The thought struck me for this invention. I don't have the steadiest hand with a hacksaw, and that leads to rather rough cuts, which in turn leads to more wasted material (sure, it's not...

Another weekend, another newbie question from Ryan ;D I'm a firm believer that one can never do too much planning in advance. While I still have no shop, and am settling on the machines I want to populate it with, I am looking at my (lack of) skills, and realizing I will probably waste a lot of...

Was just poking my nose into that $30 ignition system thread elsewhere on the forum and realized, I am not thoroughly familiar with how the common miniature engine ignition systems work.... anyone have a link to a good explanation? I've got a basic understanding of some of the components, but...

Well, I promised (threatened?) that I would start a WIP for my probably long-running design process for a scale Pratt & Whitney R-4360. For anyone curious, the R-4360 is considered the largest piston engine to ever go into production for airplanes. It was used on a variety of aircraft at and...

Another great product from the makers of autocad, is a package called Inventor. While autocad is good at letting you make drawings that can be built from, inventor is aimed more at allowing you to do 3D lockups to see if everything actually works. Some examples of what can be done in inventor...

Greetings folks, While i've already been busy asking questions, I never properly introduced myself, so here it is! My name is Ryan, hailing from the Seattle, Washington area (specifically, Everett/Lake Stevens). It rains a lot here, so there's plenty of indoor shop time to be had. I don't yet...

I've finally stumbled on the possibility of obtaining a place where I can set up a shop. As I have never actually done so, and presently don't have machinery yet anyway, I figured I'd ask around and see if anyone has ideas for ideal setups for efficiency's sake. My goal is to obtain a Sherline...

Greetings all, I'm a new member but I'm sure I'll be around for a long time. I am presently without a workshop and a little rusty on machining skills, but my CAD skills are rather fantastic, and I have been putting them to use in a new scale model engine design. The engine I am scaling as a...
