|Thread: Harrison L5 chuck datum|
Had it a few years, always been the same. All is clean, jaws in correct slots and matched set. What I havnt done is remove the backplate and check it.....tonights job
My L5 chuch screws on to a small threaded nose, but when run is seen to be out by a country mile. I checked the vertical face on the nose - zero run out, i checked the turned part of the nose between the face and the thread and got one thou run out. Im concluding the chuck or backplate is at fault. Chuck is 8" emco in good nick, 4 jaw scroll. Any advice or suggestions before I lay out for a new chuck - does anyone offer off the shelf threaded back plates?
|Thread: copper boiler with dents|
I make boilers for a living...I dont repair other peoples boilers but when I have had occasion to pul out a dent I do exactly as JP describes, you can get a car body dent removal tool off eyba cheap then machine a plug out of brass, soft solder to copper and pull out with near perfect results.

|Thread: Rocket design|
Im actually off to see the preserved Rocket this afternoon in Manchester. I built a 7.25 gauge Invicta and experienced the problem of axle movement first hand. Tight suspension cured the problem. So if one were to build a replica in 7.25 gauge either inclination would be accurate?
|Thread: Commercial boilers|
Thank you David, you are toyally correct. Problem is people are mixing one set of regs with another. Southern fed code states 2x wp, PED doesnt. What SF book does state is that you should make your boiler maker aware that the item will be tested in line with sais regs, i.e. tested to 2 x wp. If supplied boiler is commercial and hasnt been tested to 2 x then I would be inclined to ask why?
What size boiler is it?

|Thread: Rocket design|
Thanks - just found same info on mosi - The remains of Rocket we see today on display at the Science and Industry Museum look different from the locomotive seen at the Rainhill Trials, partly because of the dull patina of its finish compared to its bright yellow paintwork when it was first made. A larger smokebox has been fitted to its front end, and its cylinders have been lowered from the upper part of the boiler down to a near horizontal position.
Doesnt say why though.
The rocket, currently on display at MOSI has cylinders at about 5 degrees from parallel to the ground and yet in most illustrations they look to be nearer to 45 degrees, can anyobe shed light on why this is?
|Thread: It's about time|
I use them as follows - inlet steam line 4mm od (5/32) and outlet 1/4", they dont need to be any bigger and will very happily run on 15psi if just for show. Ive got a video of one running on test here **LINK**
|Thread: Steam Engine Number One|
As per what Jason has said, without a crosshead guide it will bind up and not run. Make the port geometry bigger if space allows as the restriction will impact on torque. The D valve eccentric rod has to be adjustable or you will never get it to run at its best. Lots to think about. What are your plans for the boiler - going to be big! Good luck.
|Thread: Wooden display base|
theres a chap on ebay sells them cheap - type in plinth - I use them to display my boilers and they are well made solid wood
|Thread: stevensons rocket|
Rockets by hornby always on ebay
|Thread: Oil container|
I use a fairy liquid type bottle with tube glued on the end
|Thread: Boiler certification in a launch|
As a steam generatingf item of such volume it most certainly has to conform to the pressure vessel regs if commercially built. The tables and requirements are set out here - **LINK**
|Thread: Imminent rabbit invasion.|
Perhaps it means they are safe to charge the Anne Summers Rabbit !
|Thread: Drill or Mill?|
Ive got ab SX mill - you can drill with it but its not ideal - there is a counter spring but mine is so weak as to be useless. I bought a second hand mill/drill, lots of companies sell these branded under various names but it is big, powerful and accurate, and good for drilling. Quill length a bit restrictive but a verey solid build.
|Thread: Carbide insert|
I use ali inserts all the time for copper and concut that the third letter must be G. The shiny ones Andrew pictured are CCGT, you can get a box of 10 for under a tenner from china. They last ok and can be used at relatively low speeds
|Thread: Unusual Oscillating Cylinder Locomotive|
If you would be willing to sell this I would be very tempted as I am looking for something unusual to showcase one of my bigger gas powered boilers - guaranteed not to sell it on? I ought to call in on Joe more often, if I had I would have bought it.

|Thread: Oxy Acetylene or Oxy Propane?|
I use oxy-prop in the business of making steam engine boilers commercially. I used to use acetylene but the price is prohibative to say the least, then there are the insurance considerations and god forbid there should ever be a fire resulting in the whole estate being shut down for 48 hours while the bottle cools! Same fittings, same torch, flame not as hot or stable but complete no brainer for me.
|Thread: Pickle for Cartridge Brass|
Even new sulphuric acid does this, it removes the zinc leaving the copper in place and is a real pain to get back to brass. I never put brass in any pickle. Some say use citric acid but it has ecactly the same effect, just takes longer. Wipe them down with a solvent then clean them up with a fillament abraisive wheel, then a scotchbrite wheel then polishing mop and paste - i use this method several times a week so I know it works.
|Thread: Best supplier of small BA hex nuts and bolts|
