Truly a beautiful cannon. I could only imagine the work, expense, the endless hours, the skill, needed to fabricate this interesting hunk of metal....and I could also imagine the pride and joy that results from your efforts. Thanks for the pictures.

Just a suggestion: Plenty of model, compression-ignition engines to choose from. Check out the "MLA Diesel Engine"....a design that can be made from bar-stock. Many have made this engine, over the years. Mess up a part, just re-machine it from scrap. No castings, no jigs, no fixtures...

petertha- Just read your suggestions and read through all your links. Many thanks for the help.....especially for linking me to the information regarding Howell's D-bit. Frank

bazmack...will do. Thnx, Frank

Thanks for all the suggestions and ideas for alternative solutions. Swifty....never thought of that....making a very long spade bit. Thanks. Using my Silver & Deming drill bit mounted into a long extension seems like a viable option. Once a portion of the 17" deep pilot hole is...

Dale, Thanks for the suggestions. My first cannon barrel was step drilled, and the final hole was generated using a .750" X 18" OAL drill bit. I was actually astounded that I was able to drill such a deep hole, so easily into steel. So with my success, came the idea to go bigger, and...

My problem: I need to drill a blind hole 1.250" diameter, about 19 inches deep into a piece of round bar stock, 3.00 inches in diameter. I have a .750" drill bit 18 inches OAL. This will give me a pilot hole approximately 17.500 inches long. I could open the pilot hole with larger diameter...

Nice to see this modern, computer-age alternative to all those rough, casting kits of the past. Steam, gas, hot-air, compressed-air engines, that could be more easily assembled from laser-cut plate, bar-stock, and some fasteners....would be a very good thing. Frank

My worst "stupid" moment....Pumping away, overly fast, with an old-fashioned pump-drill. Just had to drill that 1/16" hole....had to hold the work with my hand! The drill lifted out of the work-piece on the upstroke, and plunged down through my thumb on the down-stroke. Ran around the...

Rail- Thanks for the video and the added information. Generally, in the process of cleaning up, removing surface imperfections, rust, hammer marks, and the profiling of a blade blank on a belt sander, the flat surfaces of the blade are usually ground down to level the steel. The original...

So...here's an update: Since my last postings, I have met a professional knife-maker who lives only 20 minutes away from me. Never knew anything about him until last week. We met, and became instant friends. I have been invited to use his shop equipment, and he will guide me along on my...

TMB... Steam, Gas, Compressed-Air? What kind of engine do you fancy? With your 7-8 years worth of machining experience, you can probably build a decent, bar-stock engine, for starters. The "Downloads" section, posted on this form, shows the drawings for many engines that will fit your needs...

Just use the drawings and make the crankcase, and various other parts from bar-stock, flat stock, and weldments. The dimensions, and relationships of the various parts are what's critical. I would think with your experience, and access to machines, it will not be too much of a problem. Good...

Ingenious mechanism built by very clever machinists who love to share with other model makers, and hobbyists. I too, share your excitement Brian when I view these mechanisms, levers, bell-cranks, etc, all working their individual magic, in perfect concert, doing what they were designed to do...

Hello- You are in luck if you want to make a scale model version of the old Lister vertical, stationary diesel engine (single cylinder). Contact a gent named Eric Hale ([email protected]) also on Facebook "Lister CS 6/1 Model Diesel Engine" He has plans/kits. Plans 30 pounds/free pdfs.... if...

Hello members... This original thread posted by Alex, shows videos of the gearless, star-ratchet mechanism that Brian Rupnow is using on his vertical engine design. In concept, I believe these two mechanisms are very similar. I enjoyed reading through both threads and builds. Thanks, gents...

Dave- Thanks for giving me/us the correct term, i.e. "pendulum governor".... Sorry for the confused terminology. Frank Frank

Thanks for the interest, comments, and encouragement. Many years ago I had a friend who was a professional knife maker, and I spent many hours helping him produce high-quality knives. Spent too many long hours sitting behind display tables, at knife and gun shows, keeping him company while he...

So...back in March-2013, when I first started this thread, much has changed. Oh, I still want to make some knives, and, hand-file the bevels. "You-Tube" is a wonderful thing. I found all the tutorials that I need regarding the hand-filing of knife bevels, and I will use a simple jig that...

Hello Brian- and others.... Very interesting to see and read about this star-ratchet mechanism. The video shows it all, including the spring loaded/adjustable, governing mechanism. Maybe my references to "intirtal governor" was the wrong term to use for this set-up. The Olds Vertical...
