00:00:00.030 this is a PMR boiler I'm just recently 00:00:02.86900:00:02.879 made as you can see it's a riveted 00:00:07.94000:00:07.950 construction which is then silver 00:00:10.82000:00:10.830 soldered to make it watertight 00:00:13.24000:00:13.250 it's an American boiler and it's 00:00:16.76000:00:16.770 available as a kit of parts from America 00:00:19.34000:00:19.350 and you can find it easily on the 00:00:21.65000:00:21.660 Internet the pipe work that you can see 00:00:26.99000:00:27.000 has been added on extra by myself to sue 00:00:30.43900:00:30.449 my own purposes if you like the boiler 00:00:34.72000:00:34.730 comes complete with the safety valve 00:00:38.03000:00:38.040 seen at the very top of the steam door 00:00:39.74000:00:39.750 and the water gauge on this right-hand 00:00:43.91000:00:43.920 side the boiler runs from solid fuel 00:00:49.75000:00:49.760 tablets and they're placed inside this 00:00:56.04900:00:56.059 cloud chamber there these two doors at 00:00:59.81000:00:59.820 the bottom appeal with a control in the 00:01:02.45000:01:02.460 draft so into there you place about 00:01:08.84000:01:08.850 three tablets like them and having put 00:01:13.46000:01:13.470 water in the boiler in a few minutes 00:01:16.21900:01:16.229 even rear steam and you get about five 00:01:22.67000:01:22.680 minutes steaming out of three tablets 00:01:25.53900:01:25.549 having brought the water up to 00:01:27.44000:01:27.450 temperature here we have the smart box 00:01:34.17900:01:34.189 you can see out there and that copper 00:01:38.74900:01:38.759 tube is my attempt at making a super 00:01:40.88000:01:40.890 heater and it's an extra really and 00:01:44.85900:01:44.869 something I've come up with myself if 00:01:48.17000:01:48.180 you have a look here of the pipe work 00:01:50.28900:01:50.299 you can see the steam comes out the 00:01:53.74900:01:53.759 steam door through that pipe there into 00:01:57.74000:01:57.750 the super heater which looped round like 00:02:00.49900:02:00.509 that back out that side down there 00:02:06.19000:02:06.200 through the globe valve 00:02:10.67900:02:10.689 displacement lubricator and then into 00:02:13.47900:02:13.489 the engine this brass pipe here takes 00:02:17.25900:02:17.269 the exhaust from the engine up into a 00:02:20.35000:02:20.360 chimney then out once fear that brass 00:02:26.05000:02:26.060 spine therefore the exhaust is an extra 00:02:28.42000:02:28.430 and I've just simply soldered it into 00:02:31.24000:02:31.250 the base of that tube which forms a 00:02:34.17900:02:34.189 chimney the finial to the chimney as 00:02:36.78900:02:36.799 well is an extra item and if you were to 00:02:39.88000:02:39.890 do one you could make one any 00:02:41.44000:02:41.450 particulars share but took you fancy 00:02:46.55900:02:46.569 because it's an American boiler most of 00:02:50.64900:02:50.659 the bushes that supplied with it have 00:02:53.28900:02:53.299 American threads in so before I actually 00:02:56.58900:02:56.599 went to the trouble of solder in the 00:02:57.72900:02:57.739 main I remade those bushes with Hemi 00:03:01.33000:03:01.340 threads to sue English stuff and the 00:03:05.92000:03:05.930 only one that had to leave as an 00:03:07.33000:03:07.340 American thread was that one there for 00:03:11.14000:03:11.150 the safety valve there between the two 00:03:14.84900:03:14.859 rows of brass nipple or a piece of long 00:03:18.49000:03:18.500 brass tube which I took the opportunity 00:03:21.64000:03:21.650 of cutting in half and joining together 00:03:24.93900:03:24.949 with to model engineer threads through 00:03:28.89900:03:28.909 that brass collar there that to enable 00:03:31.59900:03:31.609 me to connect an ore to 300 psi gauge 00:03:36.27000:03:36.280 the testing purposes of the boiler once 00:03:38.92000:03:38.930 it was finished I think if I was doing 00:03:42.15900:03:42.169 it again I would remake that Bush there 00:03:47.09900:03:47.109 to be 5/16 semi thread and recut the 00:03:55.99000:03:56.000 thread on the bottom the brass nipple 00:03:57.58000:03:57.590 there to suit leaving the American 00:04:01.83900:04:01.849 thread at the top to Kennedy safety 00:04:03.81900:04:03.829 valve and only that only because really 00:04:06.75900:04:06.769 the safety valve is included as part of 00:04:08.34900:04:08.359 the key and it says buy an onion 00:04:10.00000:04:10.010 one from an English sauce so the boiler 00:04:16.14000:04:16.150 basically works quite simply the fire 00:04:19.97900:04:19.989 runs along the bottom of the boiler up 00:04:24.49000:04:24.500 through a cutout in the bottom half of 00:04:26.98000:04:26.990 the boiler there then back along the 00:04:28.93000:04:28.940 center of the boiler in five fire tubes 00:04:32.87900:04:32.889 which you may just be able to see in 00:04:36.55000:04:36.560 that shot there if our venting into the 00:04:39.25000:04:39.260 smoke box and out through the chimney so 00:04:42.67000:04:42.680 it means it's quite an efficient boiler 00:04:44.52000:04:44.530 it does really resting quite quickly 00:04:48.45000:04:48.460 they pressure gauge you can see there 00:04:52.33000:04:52.340 again is something that I've added on 00:04:54.12900:04:54.139 and it's a not to 80 psi gauge because 00:04:58.42000:04:58.430 the working pressure for the boiler it's 00:05:00.87900:05:00.889 60 psi and that's the pressure at which 00:05:05.89000:05:05.900 the safety valve laws this glove valve 00:05:11.40900:05:11.419 here is a second tap off from the steam 00:05:15.10000:05:15.110 dome to allow a second engine to be run 00:05:19.36000:05:19.370 from the bottle at this side but without 00:05:20.89000:05:20.900 the benefit of the super heater in the 00:05:23.77000:05:23.780 firebox on the outside 00:05:25.68000:05:25.690 it's quite an attractive by the way it's 00:05:28.18000:05:28.190 made if you bought it as a made-up kit 00:05:32.05000:05:32.060 from America they usually come painted 00:05:34.87000:05:34.880 black but because I made it myself 00:05:37.83900:05:37.849 chose not to parent Ian left his polish 00:05:40.54000:05:40.550 copper which looks quite good so there 00:05:45.58000:05:45.590 you are they say it takes about two days 00:05:48.37000:05:48.380 to make I think he took me longer than 00:05:51.76000:05:51.770 that but that's partly to do with the 00:05:54.79000:05:54.800 fact that along with the key to 00:05:56.43900:05:56.449 materials for the boiler you also get 00:05:59.23000:05:59.240 the materials to make the tools that you 00:06:01.77900:06:01.789 need to make the boiler these include 00:06:07.64900:06:07.659 enough tool steel to make the rivet 00:06:14.43900:06:14.449 snaps you can see there that's the domed 00:06:18.12900:06:18.139 one 00:06:19.90900:06:19.919 and finally riveting all the rivets 00:06:22.95900:06:22.969 that's the square Jean - and that's the 00:06:29.86900:06:29.879 pull-up - you also have enough steel 00:06:37.48900:06:37.499 there for the bottom dolly for the rivet 00:06:39.37900:06:39.389 in which goes inside the cylinder of the 00:06:42.05000:06:42.060 boiler hmm this Ben had it held in the 00:06:45.08000:06:45.090 vise and the boiler shell slipped on 00:06:47.80900:06:47.819 over there and they've really has locate 00:06:50.95900:06:50.969 internally into that dome cut out there 00:06:54.55000:06:54.560 and I'm dolly the other thing you get 00:06:59.14900:06:59.159 steel for is the flaring - which is 00:07:04.07000:07:04.080 basically a piece of hexagon steel which 00:07:09.20000:07:09.210 you cut in half and ship at one end with 00:07:13.15900:07:13.169 the 45 degree taper for flaring out the 00:07:16.30900:07:16.319 fire tubes and then with a stepped 00:07:19.82000:07:19.830 arrangement of the other end for 00:07:22.21900:07:22.229 converting the flare into a rivet effect 00:07:26.68900:07:26.699 really on the fire tube in the boiler 00:07:28.90900:07:28.919 prior to solder it so all that's 00:07:31.64000:07:31.650 included you just have to do the Machine 00:07:34.24900:07:34.259 in to make it work 00:07:41.25000:07:41.260 so there we are at this end of a toilet 00:07:44.87000:07:44.880 I've fitted a one-way valve or filling 00:07:50.73000:07:50.740 the bottle with water as steaming 00:07:53.43000:07:53.440 progresses and you can see there the 00:07:56.72000:07:56.730 aluminium end plate which just simply 00:08:00.99000:08:01.000 needs a little bit of fatling and also 00:08:06.03000:08:06.040 the holes drilling for fixing to the 00:08:08.19000:08:08.200 boiler shell the tie rods as well that 00:08:10.80000:08:10.810 you can see that as far of those go 00:08:12.36000:08:12.370 right through from one end to the other 00:08:13.65000:08:13.660 they need cut into lengths and tapping 00:08:16.37000:08:16.380 or threading to take the nuts which hold 00:08:19.92000:08:19.930 a housing together the smoke box door 00:08:26.60000:08:26.610 again fixes on to the boiler shell there 00:08:29.58000:08:29.590 and the best of the chimney also fits on 00:08:33.39000:08:33.400 there this needs barring out so that's 00:08:35.88000:08:35.890 quite a tricky operation because the 00:08:38.30000:08:38.310 chimney is just a slide in fear inside 00:08:43.91000:08:43.920 so there you can see the dolls 00:08:50.16000:08:50.170 themselves on the smart box also the 00:08:53.55000:08:53.560 firebox comers die cast aluminium just 00:08:58.83000:08:58.840 need a simple bit of fettling and then 00:09:02.49000:09:02.500 drilling the hole for the hinge pins 00:09:04.62000:09:04.630 their hinge pins being formed out of 00:09:08.00000:09:08.010 1/16 inch brass rod so they're quite 00:09:11.73000:09:11.740 nice look quite well the handle itself 00:09:17.91000:09:17.920 is made out of a single piece of brass 00:09:20.30000:09:20.310 cutting two to one piece of spindle 00:09:25.28000:09:25.290 second piece to make the handle part 00:09:27.54000:09:27.550 which goes through the spindle to a tiny 00:09:30.45000:09:30.460 hole and he's actually riveted over and 00:09:32.66000:09:32.670 the far end of the spindle if you can 00:09:35.85000:09:35.860 see there needs bending over to lock it 00:09:39.12000:09:39.130 on the back of the top of the smallpox a 00:09:43.94000:09:43.950 little bit fiddly the output 00:09:46.81900:09:46.829 once done it works well now I would 00:09:49.31900:09:49.329 recommend a nail in the end of the 00:09:51.03000:09:51.040 spindle before you bend it just don't 00:09:53.79000:09:53.800 sure it doesn't break off so there we 00:09:59.55000:09:59.560 have a
