|Thread: How on earth do I build this boiler for my Fire King ?|
I would roll the conical firebox section from sheet. I would roll the rings from copper bar. Brass is unacceptable. Yes all rivets must be sealed with silver solder. You could use copper elbows for the tight bends. I have used 1/4 elbows with 1/4 pipe. As for the order of assembly, I would have to stare at a bigger diagram for a while to decide.
Using the lowest temperature available throughout would be easiest. If the joints do not have too big gaps, it is not a disaster if they melt again in subsequent heats so long as they are fluxed first. If the gaps are too big, the solder might flow out of the joint and this is a drama. Close sliding fits only, no more. If you are not experienced, do lots of test joints.
Just my personal opinion but I hate to see models built to run on air only. It defeats the whole purpose of a steam engine, with the smoke, coal and smell being the main appeal, but your model, your choice.
|Thread: Eccentric Engineering T-blade parting tool: A+|
I use the 1 mm a lot for small brass bar. I have the 2 mm too and will get around to getting the 1.6 eventually. I use them normal way up. I have several of the usual V shaped parting blades but never use them anymore. Carbide insert blade for larger diameter steel.
|Thread: 2-Part Covid Vaccinations|
We are slow, but we currently have no cases in the community, so it is not so urgent. I wish we were getting the Pfizer vaccine though.
|Thread: Fire bed|
No, it depends on the locomotive's firebox, the fuel, the type of grate etc.. You just have to arrive at a method for your loco and available fuel. I mostly fill my Simplex until coal is falling back out the fire door, especially when we had the perfect fuel, Auschar, sadly no longer available.
|Thread: Steam regulator|
The prolific builders at my club all use ball valve regulators. They are excellent.
It is not quite so black and white. Osteoarthritis can have swollen inflamed joints with Herberden's Nodes. Rheumatoid is an autoimmune process. The blood test for Rheumatoid factor is diagnostic, but not all sufferers are positive, so it can be tricky to diagnose.
I silver solder LG2 all the time including boiler bushes.
|Thread: Further Adventures with the Sieg KX3 & KX1|
Amazing work. How many hours a week do you reckon you spend in the workshop and computer, ie, all ME activities Jason? I have a tremendously productive mate, who can build a standard gauge detailed tender engine in under two years, including boiler naturally, and it is simply because he puts in huge hours. No mystery.
|Thread: Improved performance over standard V belts?|
I wish I had fitted one to my Hercus when a new belt was needed. It would have saved two weeks of difficult, aggravating, stressful work, and a new pair of tapered roller bearings as I damaged the originals because of my inexperience.
|Thread: Christmas Disasters!|
Christmas Day I was in bed with severe shingles. Visitors for Christmas were cancelled, but we managed roast pork dinner for just wife and me. Still in bed.
2019 Christmas, my beloved dog was in vet hospital with acute autoimmune thrombocytopenia. Despite blood transfusion and surgery things went from bad to worst and I called it on Christmas Day and put her down, brought her home and buried her. $12,500 for dead dog. The most I have ever spent on a car was $8000. Setting up the workshop cost $6500 initially for lathe, mill and grinder.
I am not looking forward to next Christmas!
|Thread: Virtual Meet Ups|
I should be able to join this one, and thanks for making it a suitable time. I have not done any of these zoom type things before so will need instructions please.
|Thread: New DVD Player/hard drive recorder|
I hate that! I had to print instructions for my new Iwata airbrush. Badger had a booklet with it.
The central question is is the super high end one better and more robustly built wrt electronics. Better quality boards etc.. I want it to last me out. I am sick of circuit boards failing, like my SX 3 mill drill, and my LG air conditioner, the main board of which failed and was replaced twice in its about 15 year life. Both main board and control board of SX 3 have failed. The digital readout on my lathe failed. Boards unavailable; had to buy new whole unit for $600. I know nothing of electronics so can't fix anything myself.
My Panasonic Blueray player- recorder and hard drive recorder refuses to play discs. A new reader is about $A330. The remote also is playing up, probably worn out as unit is used as receiver for last 9 years. It was close to top of range when bought. I can buy a new one similar for $900, or a flagship high end unit for $1500. I don't need all the new tricks as my DVD library is not even Bluray, just old discs of favourites like Dads Army, All Creatures, Brideshead, etc.. I want longevity as in 10 years, you probably won't be able to buy them. Might the top model have higher quality electronic components than the consumer models? Or will it just have more wiz-bang stuff you never use?
|Thread: Professional Rotary Broach|
Cello, your workmanship reminds me of the laudable Graham Meek.
|Thread: The demise of Australian Model Engineering Magazine|
We have some articles in preparation which I suppose will now be sent to ME. I was not going to resubscribe to ME because of the missing issues episode, but I will now, as otherwise I will have nothing popping into the letterbox.
|Thread: Drilling through bronze|
Can we can we assume sharp drill with even length flutes? Piston valves should be able to float a bit on their spindles anyway so the valves can self centre if the spindle is not dead parallel to the bore. I made a split collet for my 7/8 piston valves so I could end to end them without marking the surfaces, and used 4 jaw and DTI for these critical jobs.
|Thread: How accurately are you tramming your mini mills?|
I just rotated the head to be perpendicular to the table on my SX3 and it seems fine. Perhaps I got a good one.
|Thread: The demise of Australian Model Engineering Magazine|
|Thread: Case hardening a part with tapped holes.|
You could experiment with a bit of scrap with a couple of tapped holes. Case harden, put in vice and torque up M5 screws tight. Or, you could put screws/grub screws in the holes before treatment so threads are protected from the hardening compound. This would also keep the threads clean.
|Thread: Citric Acid Pickle Question|
Citric acid grows bugs unless you take measures, like putting a bit of bleach in it. I use it for small brass fittings in the workshop but for anything larger, it goes in the sulphuric outside the workshop. I make fresh small amounts of citric if it has been more than a few days. The real nightmare in the workshop is HCl, as in Bakers fluid.
