|Thread: How much is a Chinese made GWR 5” gauge 14xx loco?|
I urge you to forget it, Simon. A friend bought a 4MT direct from China and it needs a huge amount of work to make it run, re-engineering really. As he is not a model engineer, he is paying another member to do the work, but one problem leads to another, and the repairer is tearing his hair out with frustration. It won't end up cheap, and it won't happen quickly.
|Thread: Lathe - dead centre wont reach the workpiece|
I have the same problem, with the digital readout cover effectively making the cross slide quite a bit wider. It has been a constant frustration, but the acquisition of a second lathe largely solved the problem. There has never been a situation where switching the tool to the RHS of the toolpost has solved the problem, but angling the topslide away helps some.
|Thread: A little rant about Emojis and their kin|
I share your contempt.
|Thread: Remembering Apollo 11|
It was the friendly time of about 1 pm here. I took the day off school as I thought it way too important not to watch in comfort. The film The Dish is great and quite charming, however the first 2 plus minutes of the transmission came through Honeysuckle Creek outside Canberra before switching over to the Parks radio telescope. So annoyed at this forgotten contribution was one bloke that he wrote a book called Honeysuckle Creek.
|Thread: Blower pipe V blower ring.|
Like the blast nozzle, you want the blower holes concentric to the chimney so the blower will be more efficient, using less steam, and yes, more draught from a given volume. It is not difficult to make a blower ring with 3 or 4 holes. I use the rotary table and 1 mm holes. Some angle them so they point at the choke of the petticoat which probably also helps. I read an article somewhere on hole sizes in the blower ring and what was optimal but I can't recall where.
|Thread: Supaburner's for Model & Toy Steam Boilers Explained|
Thanks for answers. One more, what diameter is the burner tube? Sorry if you said it in the video.
Looks impressive. Did you actually crimp the end trapping the wick fibres? Not ideal for silver brazing I would have thought. Also, is the lid an air tight fit, or just lacking a breather hole? Third question: how many burners to replace the 4 wick x 1/4" diameter burner I made for my Ellie tram? The wicks are ceramic by the way, a step up from fibreglass. 4). Any reason not to have 2 or more burners supplied by the same tank?
Your workshop is indecently tidy and orderly. I am jealous, as mine is like a commando training obstacle course.
|Thread: Myford Super 7 Top Slide Base - Alternatives?|
Would it be possible to machine away the damaged spigot section and turn a replacement and screw it on? I'm only going on the photo as I am unfamiliar with the S7 topslide. You'd need access to another lathe, of course.
|Thread: Superheaters in the Firebox|
The 5/16 stainless 316 elements in my Springbok go to the back of the firebox. They have TIG welded spear point joins. I'm pretty sure taking them to the back is standard. No need for support.
|Thread: Warco Mini Lathe|
Martin, the V in the saddle really was wider ( and horribly machined) than the prism it sat on in the SC3 I mentioned above. The saddle could be grabbed and rotated. The shim, and adjusting the saddle plate at the back, were an easy solution. Why wouldn't you try this very easy method first?
A friend's SC 3 had this problem. It made the lathe unusable. The fix was very easy once I diagnosed what was going on. I simply put a sheet of thin brass shim between the saddle and the bed at the front ways. It was not fixed in any way, but nevertheless it moved with the saddle. I chucked a length of 1" bms about 8" long with tailstock support and took a cut with the finest lead screw feed and sharp HSS tool. Beautiful finish. Lathe transformed into a capable machine.
It is appalling that machines like this are sold, especially to beginners who are least able to understand the faults and fix them where possible.
|Thread: Historic Frogs|
How about Freddo Frogs, the chocolate ones.
|Thread: Boiler cross tube leak.|
Before you do anything heroic, put some fine white pepper in the boiler and hydro it again. Leave it pressurised for a while. There is a good chance the pepper will calk the weep. No need to trouble any boiler inspectors with that little detail. It would probably " take up" with a few steaming anyway.
|Thread: Making High Speed Steel Injector D Bits|
|Thread: aching ribs - posture|
I dragged my large copper sheet out from behind the lathe a couple of weeks ago to cut some off. I have since paid half as much on chiropractors as the 3 mm full sheet cost! I often feel pain in the ribs that is referred from the spine.
|Thread: Turning Cast Iron question - Health & Cleaning Up|
I have a pump pack of sorbolene cream in the workshop and roll of quality paper towel. I do a preliminary hand wash with this. Then inside in the bathroom I have a dedicated workshop hand towel for the initial soap and water wash. I love cast iron and don't share the common objection to machining it, although it does get in your nose and lungs to some extent.
|Thread: Great service from Model Engineers Laser|
In 2009 I ordered a tender and cab kit for my Springbok. Recently I dug out the cab window frames to study how to use them, and noticed that one set of two was badly cut as the stock must have moved during cutting. I emailed Malcolm including a photo. He got straight back and said he'd send a replacement. It arrived today. This is ten years after the order, don't forget. How is that for service?
|Thread: Vickers Bl 8 inch Howitzer cannon of 1917|
Only because I know my limitations Mick.
Wonderful project Mal. I hope to see it on the cover of Model Engineer when it is finished.
|Thread: Removing Flux|
Is this a trick question Paul? The obvious answer is sulphuric acid. A friend recently found 1 litre bottles of concentrated H2SO4 in a cleaning supply shop. Cheap too. The plastic bottles are weirdly heavy too, reflecting the concentration of relatively heavy sulphate ions. I use it at 2 molar (roughly 1:10) but that is overkill.
