|Thread: Looks a lot like plastic|
Just checking out the competition and saw this burner - nothing wrong with the burner but the white part on the end looks very much like plastic/derlin. https://www.hobbysteam.com/store/4-burner-only-120mm.html?fbclid=IwAR11W7uXh3ovgd4dpfHFmHb-g8uynmTDTDxcLXqEglVoC0iYbI2YCHFsgQU
|Thread: mini grinders|
I use a Dremel every day at work making boilers - they tend to last about a year of low speed use before the speed controller fails and it goes open full speed - which doesnt work for me. Argos offer an extended warranty which serves me well. Never had a motor fail. I always keep a spare in stock, just in case. A superior tool which gets a lot more use is the Proxxon long neck mini grinder - I use the 2" abraisive sanding pads and it gets used a lot - I keep two as back ups. They regularly go pop but thats due to copper dust getting into the switch controller. Thankfully they are cheap and easy to fix. I have three of these in different parts of the workshop and wouldnt entertain working without one.
|Thread: Mill Quil play before lock down|
I have two of these and only recently have I noticed this problem. You cant move the head as its on a round column and when loose will revolve. I have taken to keeping the bit as close to the work as possible at start up, keeping a slight bite on the quill when lowering and then tighten it back up - not ideal I know.
|Thread: Tube Benders|
Making boilers for a living means I sometimes have to bend a lot of copper tube. The small tool above does a very good job but the bigger tool can be a nightmare to get right as the copper wants to crease rather than bend, Buy extra tube and perfect the technique. I measured radius as 1inch to centreline.
|Thread: Machine movers|
**LINK** facebook page. I have used this chaps services and wouldnt hesitate to use him again.
|Thread: Green Anodising Dye|
The green seen on bacon is a result of added Nytrogen (injecyed when it is packed to preserve the meat) forming nitrate (Nitrogen and oxygen) and then reacting with the myoglobin on the surfave of the meat. Not all profesional boiler makers know that!.
|Thread: Crossfeed inaccurate|
the cross slide on my L5 bears no relation in terms of scale printed on the dial to what it actually does - its a genuine L5 dial. For 10 thou dialed in it moves just shy of 8 thou. Thankfully I have a good DRO !
|Thread: Wire wicks|
Pleased to know that i wasnt the olnly one never to have heard about these. I will be conducting a few trials in the near future to determine flow rates etc.

|Thread: Middle of Lidl|
i bought a box today - thanks for the heads up. I will need to blunt them for my use but great price.
|Thread: First Locomotive|
which loco is it?
|Thread: Redesigning a boiler from 5 to 7 1/4"|
After zooming in I can see them -
Is there a chimney and associated draughting on the 5" boiler - if not then i seriously doubt (infact am certain) that it wont make steam. Scaling it up would just make it worse. No fire tubes, water tubes or cross tubes? I must be missing something - but to answer your original question yes its a simple scale up. As JB has said you might need to look at the flat areas but increasing the thickness will sort that. Ive made lots of 5" and 6" dia verticals and they dont require any stays - but I do work everything out in cad first to ensure I comply with the build codes and safety margins. If you follow the ozzy codes you will comply with the rest of the world. UK codes are fine for UK but lack detail.
|Thread: DRO's and mental agility|
For repetative work on the lathe they are invaluable. As stated earlier, I dont know how I ever worked without one. Mine are cheap chinese DROs, 2 axis is under £200, glass scales and repeatable accuracy to a tenth of a thou. Its only when you have a dro that you realise how much unwanted movement can occur when machining what would otherwise be thought of as a solid set up. Definately worth the outlay and you still need a brain to do all the maths.
|Thread: Testing Medieval Gunpowder|
Until quite recently I used to make my own fireworks, and lots of them. By far the most critical component is charcoal. It had to be air float quality, amything less will render the mix useless apart from making lots of smoke. You can grind it by hand but its very hard work so making it pre industrial revolution must have been very difficult. Its not hard to make a fountain which goes twenty feet in the air but i dont think the neighbours were all that impressed! Making boilers isnt half as much fun.
CUP do a paste but for some reason its not on their website and you need to buy it ib a big tub. I use it as a base and blend it with other fluxes to obtain exactly what I need, sometimes soldering up ten boilers in a day so it needs to be right. If you dont do much silv soldering you can buy solder and flux ready mixed in a paste - its about £15 for 10g in a syringe. loads if you google it.
|Thread: LBSC drawing costs|
As far as I am aware Curly didnt leave the drawings to anyone when he died - there is no chain of custody and hence no copyright in existance. Several companies claim to have copyright but in actual fact none can prove it.
|Thread: Harrison L5 lathe reverse|
My L5 is screw on chuck - be very careful, even hitting the clutch-brake hard can send the chuck spinning off so reversing it is a definate no no.
|Thread: Ceramic Burner|
you can certainly power a six inch boiler with gas - i make my living by doing it! What you cant do is make one big ceramic burner. Such a burner, if made correctly needs a very precise gas velocity and once the diameter goes above about 1.75" this is lost. With no draughting and small bore fire tubes you will be heating the opposing boiler face and not much else which defeats the point of having multiple tubes, as mentioned in my previous response. You need several small burners and their air intake needs an unhindered supply of cool fresh air i.e. not drawing air from inside the boiler shell. If you look at the photos of our 5" vertical boiler on our website **LINK** you will see the air inlet sticking out the side ofthe boiler base, photo 3.
