Thanks again John Reid for recommending them so many times. Opening the box: It was a rainy day today, and we couldn't get out in the field, so I've already ran it 5 times. The following 2 videos were taken on its 4th run: I was curious how far it would go on one boiler/burner filling. I filled the boiler with room temperature water, so some of the gas was used up heating the water. I was running on 0-72 track, so I figured the circumfrence at 226.195 inches or one lap is equal to 18.85 feet. I started the run at 11:50 and went until 12:08 (a total of 18 minutes) and then the gas tank was empty. The loco traveled exactly 175 laps. If 1 lap is equal to 18.85 feet, then the 175 laps is equal to 3298.75 feet traveled. 3298.75 / 5280 = .6248 miles, which is pretty close to .6250 or 5/8 of a mile. So this means my loco traveled 5/8 of a mile in 18 minutes. I decided if I already have this much info, I may as well figure out the speed. 18 / 60 = .3 mi./hr or .625 / .3 = 2.083 mph is close to the speed the loco was traveling. It's not exact, because I rounded the run time off to 18 minutes. I looked up what scale 0-gauge is and found several numbers, but chose to go with the average scale of 1:43 and 1:48. At 1:43 scale, the loco is traveling at 89.57 mph and at 1:48 the loco is traveling at 99.98 mph! (And I had the regulator almost shut, running it slow ) EDIT: at the scale of 1:20.3 that Tony has given me, the loco was traveling at 42.28 mph in my video. (Let me know if I made any mistakes, it's been awhile since I've done this much math. ) Nick I just checked how much water was left in the boiler after the run and there was 20 ml. If I had boiled the water then added it to the loco, I think I could have gotten nearly a mile on one tank of gas. But I am averaging 20 minute runs heating the water with the burner, so I think I will stick with running it that way. whistleman Nick- I think you're on a winner there!   Les That is very nice Nick. Two questions though, did you get it direct from Mamod and was there gas in the tank when it arrived?? Nick Les wrote: That is very nice Nick. Two questions though, did you get it direct from Mamod and was there gas in the tank when it arrived?? Direct from Mamod, I ordered through this site: http://www.mamod.co.uk/ There was gas in the tank, but only about 30 seconds worth. Nick I also thought it would be ready to run, but this o-ring was right here on the steam line. It was a quick fix, but not the best quality control. tmuir I think you will find that Mamod although runs on O guage track is a much bigger loco than normal O guage locos it. It isn't based on any prototype so the scale is just a best guess really but I think you would find it closer to 1/2o scale. I did a similar thing ages ago with my old Mamod. http://modelsteam.myfreeforum.org/about4011.html and I was trying for top speed and got 6.651 kmphr or 4.13 miles an hour. A quote from my post on working out speed. 'Mamod locos are not really built to any scale but as Roundhouse locos are 16mm and Mamods are a bit smaller we will say its 15mm That means 15mm = 1 foot (I know mixing mm and feet but I didn't make up this scale ) which converts to 1:20.3 so times our speed by 20.3 for the scale speed which gives us Scale speed of 135 kmphr or 83.8 miles an hour. ' Glad to hear your loco worked well stright out of the box. Nick Thanks Tony!  I knew the locos weren't made to scale, so I just picked O-scale for the fun of it. I'm off to check out your old thread now... Les Nick wrote: Les wrote: That is very nice Nick. Two questions though, did you get it direct from Mamod and was there gas in the tank when it arrived??

You should of had it posted to me, it would have saved you about £40 overall.   Nick Maybe Mamod does listen? I noticed this message on Chris Cairns video: Quote: that box isnt very good, plenty of room to move around and get damaged http://www.youtube.com/watch?v=imZwlU3KzXU&feature=player_embedded And he was right, I took this pic from Chris' video: But notice the newer box: With an extra insert: Les They didn't use the insert when John's loco was delivered here, I had to put extra packing in to keep it secure.

I was just in a hurry to get one bought before they raise the price again (which I think they will) and didn't even think of having it sent to a forum member. How did you keep John's under 2 kgs? Did you ship it in two packages?

Did you ship it in two packages? By cutting down the outer box slightly, but they were going to charge John £80 postage.   Nick Glad I didn't get stuck paying £80 then! johnreid Your has the hole in the cab roof for possibly filling the gas? Mine doesnt but I noticed that Alans did in his video as did the one in Chris's video. I just take the tank out each time, although it would be nice to buy a tender and somehow keep the gas tank in it. I guess I should give that some thought. Although not really to scale, mist tell me they are SM32 narrow gauge. I am sure that you willl enjoy it, mine is a lot of fun, I still say the best buy for the money out there. Nick johnreid wrote: Your has the hole in the cab roof for possibly filling the gas? Can you get a filling adapter long enough to reach the tank through the roof though? pauly Roundhouse sell a long gas adaptor. Nick pauly wrote: Roundhouse sell a long gas adaptor. Thanks Pauly! Now I know they're available. I'll check some camping stores first though. Graham-Jilly Great engine there Nick looks like a lot of fun Nick Video soon...

Johnreid, is this what you mean`t?? : I find it a great adition to my Stock!, It is built to fit behind any of my Loco`s, It is fitted with armoured Pipe!. Regards, John.

Minor1PJG wrote: Video, video, video.       Alright, alright! Video very soon. Layfield light rly why on the box does it say age 14 plus or with supervision and then at the bottom age 16 plus or with supervision? Nick Before you ask Les, the video is not made yet.

So how soon is soon??   PCLR pps models sell long gas adoptors??? johnreid That long one looks nice, I am tempted to drill a hole in the roof of mine, but I probably will not. I wonder why mine is without a hole in the roof?        The Unofficial Mamod and Other Steam Forum Forum Index -> Locomotives Page 1 of 1
