Bob; Howdy from the sunny Okanagan! I went thru this cast iron exercise recently and had no luck finding material this side of the border - Edmonton had it but it was special order and you had to order at least 12 feet of it :o. Like you I found metals Supermarket didn't stock it - I've...

Thanks for the build posting Chuck! Any chance you could post a short video of the engine running with the lower compression for comparison, or is that what you've already posted? It never fails that I learn a lot from your work - much appreciated. Cheers Garry

Nice work! I think this is his source for the castings..... http://www.classic-motors.at/modellmotoren/modelengines.htm Cheers Garry

....so we left a few beer cooler doors ajar....adapt people ;) Cheers Garry

Austin; I can only speak as a newbie to this machining/model engineering HOBBY, but I guess that makes me part of your target audience. I signed up for HMEM Version 1.0 NOT because it had/will have polished, well written articles; but because it very obviously had many highly skilled machinists...

Rob; Congrats, I have the same lathe. As for spare parts start here; http://www.busybeetools.com/pages/Customer-Service.html I generally call customer service 905-738-5115 (usually talk to Ameen ext 6506). Parts aren't listed on the website but Ameen knows the products well and can...

Matt; You might want to Google the "Henry Ford First Engine". It's simple enough and many of the parts are store bought with minor machining. From this forum; http://www.homemodelenginemachinist.com/f31/henry-ford-engine-7985/ As for the idea of building a lathe and mill; I started down...

A few sites that may help; http://www.5bears.com/pistons.htm http://www.jerry-howell.com/PistonRings.html http://www.metalstop.com/technical/wal-ring/wal-ring-a.html Cheers Garry

Welcome Owen - from down the lake! The three of us could form an Okanagan Chapter of HMEM :D Looking forward to your posts. Cheers Garry

With steel I had trouble getting a good surface finish until I started using Tapmatic cutting fluid instead of WD40 or whatever oil; started using the tailstock center to support the work (too much overhang and deflection) and used this lathe tool to remove the last two or three thou of metal...

Will this do? http://www.john-tom.com/MiscrPlans/GermanVengine/VGerman01.pdf Lots of other plans on the same site. Cheers Garry

Keith; Thanks for the clarification on the surface finishing. Cheers Garry

Keith; Is the method of finish on the con-rods the same as you applied to the cam covers on the V8 ? ; "Then into the hand cabinets for a blast of fine glass, then a blast of 170 steel shot, at low pressure, say, 16psi." I assume this was done in an industrial setting. Is there a "home...

The family of Mr. Upshur continues to sell plan sets; http://upshurengineworks.com/ Cheers Garry

Keith; Go cat go! Enjoyed the V8 build and looking forward to the V10 build. If the twin turbos don't pan out how about doing the supercharger like they did in the early drag racing and Bonneville salt flat racing days (AKA Potvin setup) - run the supercharger right off the end of the...

Thanks Roy. You can +1 me in the "when I can be bothered" column :D Cheers Garry

has anyone tried this fix/improvement for backlash on the X2? http://www.fignoggle.com/machines/x2mill/howTo-antiBacklashNut.htm Cheers Garry

Rich; Just on the off chance you're not aware; DraftSight is download-able for Linux (Fedora or Ubuntu) and is considered to be "AutoCad-like", an easy transition. Like you I've moved to Linux (Mint 13 KDE) on my netbook as a test. I'm suitably pleased and will load it on my notebook...

Aside from the issue of machinability; the difference appears to be the depth of hardening and the hardness rating achieved. http://www.onlinemetals.com/toolsteelguide.cfm http://www.alro.com/datacatalog/tooldiesteelhandbook.pdf Just a note; don't forget the "slightly" undersize and...
