Hi all. My name is Rafael, and I live in Colorado. I have been hanging around the forum for some time now and finally decided to join the fun, though I have no practical experience. Building an IC non compression engine is my goal and need help with the Hall Effect component. I purchased the...

I've decided to start a new thread to announce my collection of miniature tools and the tool board / box and work bench I built to display them. I'm also working on a video that will hopefully show more detail. Ralph

This isn't about engines, but it is about a craftsmanship diversion I recently took. I built one, and that lead to others - not sure I'm done with this yet, :confused: but engines keep creeping back to my mind. Ralph http://youtu.be/XujBf40POcY

Another update on this wheel grinder. Just couldn't stop :wall: I wasn't sure how to post it, but I think that it is really finished now -- soon as I start another project. Ralph http://youtu.be/up3TYj5n-TM

Just finished an updated version of my miniature wheel grinder with some added mechanical features. Maybe now it is really finished - if anything really ever is. Ralph http://www.youtube.com/watch?feature=player_detailpage&v=LlkZdGzZ69w

Some time ago I posted a picture of my "Treadle Wheel Grinder" with thoughts of posting an action video. The two finger engine required more dexterity than I could muster. :shrug: So it progressed into a solenoid & moment arm powered model. :confused: Now I can work it just fine. Click on...

In an earlier thread I had published build pictures and a video of my treadle powered Miniature Brass Lathe. I have now figured out how to power it with a solenoid and moment arm arrangement. Ralph click on picture

Here's another Simple Solenoid Engine built just for fun and quick gratification. :rolleyes: Ralph

I've decided to take a step back and build a simpler solenoid engine. :)

I'm between projects, trying to organize my album and found the video of my 4 cylinder - 4 stroke brass solenoid engine that I built a while back. Each cylinder is switched separately in line with the main switch and a rheostat with an LED indicator light in each circuit to show cylinder(s)...

Hi all. I acquired this steam engine sometime ago and was told that it was salvaged from an old mine in Colorado. It has no markings that I can find but is two cylinder (one larger than the other) and may be missing some linkage parts. Can't find anything like on the net. I'd appreciate any...

I think that this engine is "finished" - if anything ever really is. We might attempt yet another iteration by replacing the solenoid cylinders with steam / air powered cylinders. It's operation would be very similar with power (pressure) to the cylinders through tubes regulated by valves with...

Hi All. After floundering for a while (which I don't do well), I started a new project today. scratch.gif I don't know what it is going to be yet :shrug:- I tend to build that way, but I'm hoping that it becomes an engine of some sort. Creating off the top of my head is a style that gives me...

Hi All. Thought you might appreciate a view of my miniature lathe in action. Ralph

Hi All. I've been working on a new project - a miniature brass pedal lathe. In this scale it's more of a "digital" (finger engine) lathe :shrug:. It's almost finished - if any project ever really is. scratch.gif Will try to post an action video soon. Ralph

This set of miniature solid gold hammers is for the well dressed machinist. :) Ralph

Hi All. We've got the RR Trolley in motion on a short track. Ralph

This is a 1/32 scale Rail Road Pump Trolley I've been working on. Now I'm training the Guines Pigs to work it. ;D Ralph

Hi, This is a 1/10 scale replica treadle wheel grinder like one my grandpa had (as close as I can remember) when I was a kid. This little machine was built with equipment no more sophisticated than a cordless drill and a soldering iron. The finger peddles were added just for fun and ease of use...

I sure am enjoying this Forum - spending all my spare time catching up earlier posts (incredible things being done out there) and tyring to decide how to approach my next project. In the mean time, thought I'd share an old favorite Solenoid V Twin Engine. Ralph...
