Don, A copy of plans for BAT, as well as the construction article was published in "The best of Model Engineer Volume 3" which is still available on http://www.myhobbystore.co.uk and also has some other plans/acticles

Bill, Thanks for the info. I have emailed Geoff and will update with any response Regards, Tony.

Can anyone tell me if the D.R.Mercer Traction engine models are still available? I was hoping to make the most of the good Aussie exchange rate and purchase a Type 2 kit but after emailling both forrest-classic.co.uk & minsteam.com websites but haven't received a response from either. Any...

Sovereign Hill is an outdoor museum in my home town of Ballarat, Victoria, Australia. It's theme is the re-creation of an 1850's Australian Gold mining town. http://www.sovereignhill.com.au/ For thje second year in a row they have had a special "steam day" where, along with their own permanent...

Well a little more progress to date, albeit rudely interrupted by the failure of my mill's DC Drive (see http://www.homemodelenginemachinist.com/index.php?topic=15501.msg159030#msg159030) The blanks for the impellors were machined down to size & parted off (seems a waste of 1" alluminium bar...

Noitoen - I did consider strapping a heating to the rectified before I re-installed it but thought that since the rectified was rated at 10 amps, and the mill is protected by a 3 amp fuse overheating should not have been a factor? I assumed it was just the use of cheap components that lead to...

So there I was, excited at using my rotary table my X2/C6 (Grizzly 0516) lathe/mill for the first time when without warning the spindle just slowed to a stop. Checked the speed control & emergency stop - still OK & the green "power" light was still on? Did the logical thing and turned it off...

Having recently finished my third of elmer's engines I was looking for the next project to tackle. Browsing through my library of "some day" projects I came across Elmer's Turbine/Pump set. While not real interested in the turbine itself, I thought the pump itself would make a good project of...

Joe, I have a 'pre-build' version of this engine (SOLAR-1) http://www.pmresearchinc.com/store/product.php?productid=3094&cat=5&page=1 I inherited along with the accompanying "Stirling Cycle Engines" book. I haven't had a chance to look for the book at home yet, but from memory one thing it...

Nickle, No this was Echuca rally on the New South Wales/Victoria Border - its held every Queens Birthday Long Weekend (Second Monday in June). I also attend the Lake Goldsmith Rallys (and have done since I was 18months old or so I'm told) but I dont take models - I have a 1925 Aveling Traction...

...And a short video Tony.

Just finished my third of Elmer's engines - the wobble plate engine. I'm sure some of you guys could knock one of these out in an afternoon but for some of us its shop time is severely limited and projects like this one take several months. This is also the reason I have no "in progress" pics -...

I'd just like to add another thankyou to Bogstandard for the Richontools link. I have just recieved my order from 11th Jan. I ordered an assortment of 31 endmills from 2mm - 10mm in 2flute, 4 flute & ball end for $50 Australian including postage. It may have taken 20days to arrive but compared...

Sam, This might be the information you are thinking about http://www.homemodelenginemachinist.com/index.php?topic=6415.0 I have also recently used Alum (swimming pool "Flocculant") recently to remove a M2 tap from 6061 Aluminium. I filled a plastic container with hot water, tipped in enough...

Brian, Have you considered the use of high strand copper cable in place of the steel/string? Quality Multimeter test leads are typically a high strand count, high flex cable, especially those manufactured with silicon rather than PVC sheaths. Some of this can have over 600 strands in a cable...

Bentprop, I have a copy of the 2000 reprint of the Model engine book, and while some photos are still quite dark they possible are not as bad as the scanned copy. If there are any specific photos your after I'd be more than happy to scan/photograph them and see if they come out better. Tony.

Could they not also be used to produce tapered plug valves? I'm not sure of the required angles, etc of taper pins vs valves, but I do know I inherited a small collection of tapered reamers that were used to ream the body of small steam plug valves. Tony.

Another thing that might be worth considering is that air and hydraulic testing will also differ from "real life" operation due to the fact that in use they will obviously be hot, so differential expansion of material, etc may have an effect. I have had this with a full size injector check...

Brian, There is a web site I came across quite a while ago that has some great information on steam engine design, including many "Rules of Thumb' for calculating valve sizes, piston rod diameters, etc. It might be of some interest http://www.alanstepney.info/index.html This page specifically...

While I haven't yet attempted to tackle something so elaborate as a locomotive, I have always had the "Sentinel" 5" loco from Model Engineer (circa 1961) in mind. It was a model of a shunting engine with a relatively simple vertical boiler and Stuart Turner Double 10H engine with chain drive to...
