G'day all Note that the Darjeeling boiler is 2205 Duplex not some unidentifyum. In Europe they seem to be making "stainless" steel boilers but using Grade 316L. I understand that 316L has a higher chloride resistance. A problem with stianless steels is that they can change from anodic to...

I did the same with a lever arch file of documents as i left the office rushing to catch a plane. Fortunately with deft footwork I managed to recover most of them, no injury but to my pride; it was rush hour. Ian

The bearing split is not through the axis of the bearing?

G'day J Very inventive! It looks like the wall is a stud wall (timber framed) and so will not be rigig like a brick/concrete wall hence the transmission of vibration. Some of the problem will be the belts but mosy likely it will be from the single phase motor. Motor vibration could be an...

G'day Shedboy Pickle, you will find citric acid works OK. The advantage is that it doesn't eat your clothes. You can purchase the crystal from home brewing suppliers in 0.5 or 1 kg bags. I just stir it in until no more will dissolve. Sulphuric acid is now available as drain cleaner if you want...

G'day Harry Thanks for the advice about peening and ginger. I have repaired my boiler after tubes started leaking at the firebox tube plate. We resilver soldered the tubes and they look good but I still have two pin hole leaks. I can just about get to the water side of the tube plate and...

G'day Mike I have also considered a boiler which uses the smoke box volume to get extra water space. In Oz we can buy unequal Ts as well as equal Ts at the plumbing stores; you may be able to do something creative with these. Regarding staying you could double up the thichness of the end...

G'day Paul Thanks for advice, very useful. Regarding the uneven strokes with a single acting pump. A solution would be double porting, that is separate inlet and exhaust ports at each end. By reducing the exhaust port diameter at the top end the speed of the returm stroke could be inpeeded. I...

G'day Paul Lovely little job. Now the questions. Is the valve slide connected directly to the spindle with the stops on it? Is there a valve which separately a controls the pilot piston for the main valve? Will it self start? How about a sketch! The reason for my question comes from having...

G'day Dave Others have said that power in must equal power out plus the losses in the controller. The dc power is the volts times the current. For the ac input the power is the volts times the current times the power factor. In this case the power factor at full motor speed will be about unit...

Gives a new meaning to Hot Flushes! ;D

For the record. I got a goody! Bought a little 5" gauge loco during the year and I caught her (my wife) out in the workshop looking admiringly under the dust sheet at it. Regards Ian

G'day all There is a lot of snake oil about. These "power saving devices" are generally power factor improvers which means that the volt amp product is closer to the watts drawn from the supply. Whilst improving the power factor, can't get better that 1 by definition, reduces the volt amp...

G'day all Here in Ozzie we can buy a "Road Kill Cookbook" Trouble is the meat just cooks as it lies on the road and the book is "tongue in cheek". The book caused a stir when my daughter, who is living in Atlanta GA, showed it to her neighbors. How could we Ozzies eat those cute little Koalas...

Now do it with a hit or miss! ;D ;D ;D ;D

G'day Smokey Rather than guesses, no matter how well educated, let's look at a Code. I refer to the AMBSC Code Part 1 Copper Boilers. Table 3.3.2 allows a minimum thickness for boiler barrels up to 96mm diameter of 1.6 mm for a working pressure of 700 kpa; this table 3.3.6 states is equivalent...

Tel Well done my old mate! A great engine. I must look in another place and see the video, haven't got a round tuit yet. You will have to display the Ridley next. What's next, a single crank no dead centre? Regards Ian

G'day Do house brick explode when used for silver soldering? Limekiln dry house bricks may not explode. Equally wet fire bricks will explode (well most likely). Part of the problem is how the material in the brick deals with differential expansion, fire brick can handle heat differences...

G'day Diy89 Unless you are running a tool shop the cheap DTI's, Michrometers and digital calipers are worth buying. Check out the cost against Staret and you will see what I mean. Unless it is really cheap it is better than nothing. To gauge prices for good "imitations" look up Little Machine...

G'day all Too many boo boos to mention. I just read about Tel silver soldering up cylinders so here's my effort. Keeping things together during silver soldering is always a challenge. I had an Neitsnie (work it out) when in the cheap shop. Lovely little spring clamps, just "perfect" for...
