    Building an Oscillating Engine for my first engine

    Malofix, regards! I've been following you on the advancements for your first Oscillating Engine and decided to show you mine, which was built a long time ago, before the aid of any Cad 3D software program ( something I cannot live without anymore). This little engine was first designed as being...

    Optical center punch formula

    Stone, that's what I have as an information basis. Besides the image below, please refer to the entire text: Light Key terminologies of Spherical Lenses class 10 science NCERT Then watch the short video attached:

    Optical center punch formula

    Looking forward to hearing very good news from you, Stone ! For better transparency ( as I have always done), you gently apply 360 grit sandpaper first, on the surface of the recently machined acrylic part while the lathe is still rotating, then 400 grit and 600, all soaked in water and dish...

    Optical center punch formula

    Loren, thank you for your comments. My first reply raised interest on also machining an Optical Center Punch, something which is very useful in every shop so I wish to change some basic thus necessary measurements. I hope it helps. Regards, Ron

    Optical center punch formula

    Stone, greetings! I’ve been dealing with fine mechanics throughout my life and could accomplish some unusual feats such as building Super 8 projectors, repaired optical equipment thus manufacturing small prisms and this tiny “steam locomotive”: As far as I could move along all these things...

    Free plans for a larger, simpler, beam engine

    Greetings Gentlemen, for those whom wish more details, I've just browsed the Internet and came across a few images depicting the Monitor engine main arrangement. It is indeed an ingenious design for that era. Ron

    Cad and animation

    Edi, Regarding your enquiry, the entire layout was based upon the Brazilian southeastern countryside environment and most of the constructions date back to 1920's. I have scaled down my railway from the old HO to Z ( 1:220) scale as being a big challenge to both 3D design and model tiny metal...

    Cad and animation

    For sure a very good 3D model and animation, AZBOB. The wobbling cylinder valve is quite a feat of engineering Congratulations !

    Cad and animation

    Dear Gordon, For many years, I’ve been working with fine mechanics and faced several difficult assemblies that could only be really machined with the aid of a 3D animation software. Small details that aren’t noticed or well managed during the project are promptly highlighted when the new...

    Gentlemen, following a series of images depicting the tiny "Baldwin" internal parts then an overhaul. It is now a tanker, more than ever:

    A Wright

    JC54, I have just come across this interesting live steam engine design and wonder if you can send me either any sketches or scanned drawings. The rotating cylinder design is quite a feat. My hobby is basically very tiny electric trains so I built this Z scale layout ( 1:220) some time ago. The...
