|Thread: Small air compressor sufficient to run a Potty Mill|
Yes it should I've run my engine on one. also used it to run my twin cylinder over crank engine that has a far greater cylinder volume.
Try inflating a child frog hopper bouncer and couple it up:- to increase pressure just get some one to sit on it
|Thread: Water Tank for Wagons|
Some time back I bought a part finished Tender it was my intention to use it with the Crab Loco I'm building but when I got round to looking at it I realised that it wouldn't be suitable, so it sat under the bench. Then last winter as a change from working on the Crab I decided to convert it to a water/coal wagon for my Simplex Loco. The basic conversion went well, but I really struggled to convert the brass sides into a leak proof water tank it must have more solder than brass. This got me to think if any one has converted a plastic container or made a plastic tank any comment would be appreciated.
Any way this is my Water/Coal Wagon.
|Thread: Potty Mill engine materials list wanted|
I never compiled a material list for this engine. The material is mainly low cost aluminium and steel standard stock sizes:- though I've used metric sizes it you will be no problem using the nearest imperial size.
There have been a great number of these engines built to my plans, the drawing in Thors link were done as a drawing exercise that are over complicated, if you want a set of my drawing just send me a PM with your email address and I'll mail them you.
|Thread: Help a beautiful lady|
Thank you for your replies I knew I would get some good replies from the ME community, we'll follow up your suggestion today
This is nothing to do with Model Engineering but this is the only way I could think of of starting a UK wide search. The problem is my 93 year old mother in-law has exstreamly marrow feat size AAA and she is desperate to buy some new shoes before the ones she has fall to bits. We took her to her usual shoe shop in North Wales on Saturday only to find that the shop had shut down and we can’t find any other shop who stock AAA width shoes so does anyone out there know of any specialist shoe shop who stocks them. You would make a lovely lady happy
|Thread: Adjustable workshop perching stool|
This is the thread you want posted by a guy who goes by the name of "Ye-ole steam dude"
I got my plans from the same place, but I made mine from 20mm box section steel. I wanted a project to practice my welding on, my biggest mistake was with my first weld it took me by suprise and I burnt through the box section the other were ok and they got neater the more I did.
No Jim its not the old throne its off an kitchen stool I was using in the workshop, the drawing calls for a 10" diameter seat the kitchen stool was 12" so I just cut one edge of it off to make it 10".
Waste not won't not
If I have to stand at the bench for any length of time my back start to ache I have an old kitchen stool but its height is far from ideal particularly if a move it around bench to lathe or mill or loco assembly table. Then I saw this design on one of the other forums I frequent, the seat has a clever self clamping device to adjust all you do is take your weight off it and move it to the height you want the sitters own weight provides the clamping force.
Before we have any wise cracks about the side ways photos I did turn the the correct way round but this hosting just won't load then the correct way round any suggestion why this is.

|Thread: LBSC Ayesha in Steam|
South Cheshire MES hosted the 2 1/2" Gauge Society at there track on 5th May and had LBSC Original Ayesha locomotive in steam.
Enjoy the video we certainly enjoyed the day
|Thread: 2 1/2" Gauge Society Event at South Cheshire MES|
I hope you made it to the event
For those who missed it this is the Video I took it features LBSC Ayesha running on steam no mean feat for a loco built about 1920
South Cheshire Model Engineering Society will be hosting the 2 1/2" Gauge society this Sunday 5th May. Who will be bringing along LBSC locomotive AYESHA this Locomotive is famous for the "Battle of the Boilers" held in 1922:- this battle raged between Henry Greenly, Curly Lawrence and others in the Model Engineering press for many months until they decided to settle the argument by holding and efficiency competition where Curly pitted the performance of AYESHA against other locomotives the result was a close run thing and was far from conclusive, so the controversy continued. AYESHA was at last years event and managed a sedate lap of our track which is remarkable for an 90 year old locomotive.
Visitors will be most welcome.
Our Track is Rear of Peacock Hotel, Crewe Road Nantwich Cw5 6NE www.southcheshiremes.com
|Thread: Starrett type clamps|
Thanks for your comments and interest chaps
They wern't that dificult to make.
To make the bodies a matching pair I simply bolted them together and machined them as one. I was unsure just how much the cold rolled bar would distort due to releasing the stresses:- so I roughed them out first and let them stand for a couple of days then I skimmed the base and top flat this took out the distortion.
Finishing off body
The jaws couidn't have been easier you just have to drill the M3 hole for the keep first before drilling 6.5 using the self centerng four jaw chuck
I used a M8 coach bolt to fabricate the screw and welded the knurled head in place.
Total material cost about £6 and not much more than a days job
These clamps are Based on Starrett No 160 tool makers clamps whilst I wouldn't call these clamps tool makers quality due to the constraints of home workshop construction they will be more than adequate for most home workshop. I made them as a perfect matching pair to enhance there usefulness.
There has been a number of discussions on the forum regarding these clamps with a lot of interest shown in them, the original Starrett clamps can be picked up on flebay they go for about £30 to £50 pounds and Starrett still sell them for around the same price.
Any way this is my attempt
And to show them as to one of their uses.
They are made from standard size mild steel bar Body 1"*5/8" jaw 5/8" Sq bolt M8. Starrett fixed the jaw with a cerclip but I've used a M3 keep screw.
|Thread: A close shave or why safety glasses are a must|
I was using a burr in a dremel a few months back and for some reason or other it came adrift and flew out i just couldn't find it until the other day when I found it embedded in the roof, you can only imagine what would have happened if it had gone in my eye.
I do wear prescription safety glasses all the time when I'm in my shed, never the less its was quite sobering.
|Thread: Stress Relieving Rolled Mild Steel|
Thanks for your input chaps
the part is 1”x5/8x21/2” with the middle bit removed so it’ll bend like a banana putting the ends out of square which I want to avoid
I’ll see what roughing it out first does to it I may be able to live with the results
The trick with the air tight tin/foil would do the trick to prevent scale, thanks for the tip
I have enough bar to have a couple of tries so I think I'll try rough machining first to see how much it warps.
Thanks for the useful graph, as I thought it shows the temp for stress relieving to be around 600 C our oven won't be hot enough.
I want to machine a part from cold rolled mild steel bar from experience I know that the part will warp out of square and this would be a no no, also for what I have in mind hot rolled bar would not be suitable
So has any one tried stress relieving rolled mild steel bar?. I thought about sticking it in the oven but our ovens max temp is 240 C I don't think this will be hot enough as far as I can find out you stress relieve at around 600 - 700 C I,ve also considered putting it into a barbeque but that would be a bit hit and miss.and I don't want to scale the bar
My other option would be to rough the part out and let it sit for a week or two to let the stresses work on to part, then to finish machine it but I'm unsure if this will be effective enough.
Any ideas views
