    Tandem Compound Poppet Valve Steam Engine Build, ala Cedge

    Thanks Bear. I had to agree with you... the rivets are gonna be a bear to keep polished, but I like the look too. Not much in the way of new tricks or tips of late since everything has been pretty much reapeating things already posted. Lots of holes drilled and filled to get where things are...

    A rather special day

    Bogs Glad to hear he listened to you on this one. He'll certainly get more respect and be taken a litle more seriously. Standing out from the crowd is not a bad thing. Good looking young man!! Steve

    Jerry I'm really enjoying following this build. You're doing a fantastic job!! Steve

    Jeeze guys.... LOL. Didn't get a lot done tonight, but a little progress beats none at all. I spent most of the day at a local tractor and engine show and met lots of miniature engineering fans and even a local hobby machinist or two. The valve bases on one cylinder are now ready to receive...

    I hate my Z! (Axis... X2) Ideas?

    Mark.... Maybe because I own it and simple wanted to tinker with it. It did all I ever asked of it, but I could and did make it do more than the original design. The challenge was half the fun. You can polish your whatever but the rest of us have mills to play with. I didn't think we needed your...

    Marv.... You forgot the teeny weeny little illegal... the only skilled masons left in the US....LOL Speaking of teeny weeny...I'm about to begin drilling the first of 96 holes with a #54 drill bit.... sound like fun? Steve

    Chazz... Perhaps the most elegant compliment of all times.... thank you. I got the same inspiration from surfing the German builder sites. They had what I wanted but couldn't justify spending the money it required to get them. Hobosn's choice... I began learning to build my own with an eye...

    Tandem Compound Poppet Valve Steam Engine Build, ala Cedge

    Sam Polishing is a no holds barred exercise here. Nothing is out of bounds, from files, sandpaper (100 - 2500 grit), steel wool (up to 0000), valve lapping compound, lapping paper ( 10 - .5 microns), cotton polishing mops and wheels, metal polish, automotive rubbing compound, toothpaste....the...

    Building Jerry's Donkey

    Jerry I know the fear and the elation...LOL. I cut my first gears on my last engine project and sweated bullets. Congrats on a successful adventure. The gears look great!! Now, if I can figure out all the angles, my next gear cutting will find me doing bevel gears with the single tooth cutter...

    Posted while dodging bits and pieces of Sam's head.....LOL Still taking it easy, but I did manage a little time on the mill.... for which I duly paid the toll. I'm ready to begin establishing the elevation for the crank and flywheel which will soon need to be made and fitted. The project for...

    2-56 Heli-coil?

    Marv.... Had to do just that on my current project. Stripped a 1-72 thread, re-tapped it to 2/56 and broke the damned tap off flush. Grabbed a piece of carbide to D bit the tap out and wound up with a 1/8 inch hole to fill. Pressed in a bit of brass, filed it contour and then drilled and tapped...

    Spherical Cutter

    Steve I'd be happy to post drawings.... if there were any....(grin). Like so many of my projects, it began with a rough pencil sketch, a few mental notes of where I thought things should be and then away I went. The basic design is from Steve Bedair's concept. I opened a slot on one side of the...

    Tandem Compound Poppet Valve Steam Engine Build, ala Cedge

    Sam I'm using fine needle files, relatively heavy strokes to start and go lighter as I get close to the final elevation. Then I switch to 320 or 400 grit sand paper. The paper rapidly removes the tool marks and works out the small imperfections of the contours. I then polish it on a buffing...

    Tandem Compound Poppet Valve Steam Engine Build, ala Cedge

    You guys are way too generous with the praise....LOL. Thanks to all for the flow of encouragement. Half the fun is sharing an experience that also still amazes me with each new step it takes. I'll have to admit it is turning out far better than I'd imagined it would. Ariz... I know the...

    Hit me - Miss me?

    Bob... Gorgeous work!! After the single tooth experience, I'm really wanting to try the hobbing technique. In one of the Youtube demos I've watched the guy made his hob with 10 teeth. Steve

    Spherical Cutter

    Thanks Pete I need to remake it now that I'm using a slightly larger Lathe. I have used it enough it's not quite as shiny these days....LOL. Steve

    Marv... Thanks for the kind words. Make an offer and I'll send you a bottle or two.....LOL. The island sounds good, but I'd never get a tan building engines like these. I had already thought about it looking like part of a steam powered oboe....LOL Steve

    Tandem Compound Poppet Valve Steam Engine Build, ala Cedge

    The rib is still pretty sore so I've been doing hand work and some of the details that would normally wait until later in the project. I'm really not enjoying the lathe or the mill at the moment, so no huge dramatic tricks in this post. The original engines of this sort had added support for...

    Larger mill needed

    Not sure what your needs or budget constraints are, but I've been using the Seig SX3 mill for over a year a now and it has yet to leave me in a bind for either work space or performance. I'm one happy owner. Steve

    Tandem Compound Poppet Valve Steam Engine Build, ala Cedge

    Thanks guys... I remember lots of late nights when a quick tip would have been welcome. I'm trying to share tricks as I use them. The hard part is realizing when I'm doing something that might help. I've spent enough time in corners to never forget those who helped me get out of them. If this...
