    Hi Nedshead,

    A nice find and a good job of refurbishing the stove.

    I wonder how many products made in this decade will survive eighty years and be so well designed to be able to be made workable by a bit of elbow grease, common sense,knowledge and handwork.

    Even today the unit is still useful for times when the power goes out.

    Is that the type that you start on methylated spirits and actually run on me to.

    Thanks Grahame, It'll be coming with me on camping trips, it's a handy little stove.

    I refurbished a kerosene blow torch a couple of years ago and the thing puts out some decent heat, it's also been very handy to have around the home.

    @caskwarrior, that's right, you preheat the vapouriser with a bit of methylated spirits then switch over to the tank of kerosene pressurised by the pump, once lit the pressure is self sustaining

    Default Air & Coolant Mister for Lathe & Mill

    After seeing these in use on a few YouTube sites I felt they would be a handy addition to my workshop. After checking out a few different designs I chose this one as it has individual control over both the air and coolant, in my case the coolant is ATF oil.I wanted to be able to move or remove the control unit so I made up aluminium bases each with four rare earth magnets loctited into them and screwed to the controllers base.
    In use they work really well, you can have just air or a mix of coolant/air and the range of control of both needle valves is excellent. With a bit of experimenting with my ATF oil I ended up using a mix of 1.5 litres of ATF with 250 mills of kerosine added. With this mix you can adjust the oil flow down to the point that you cannot see it, you have to place a piece of white paper under it to pick up the droplets. Thinning the mix allows for low air press/volume to be used so that you do not create a lot of mist.
    In use the small size flexible hose stays in place and allows you to place the nozzle just where you need it.This is very handy especially when parting off as you can direct all of the flow into the cut and it helps with chip removal.So far I have used both units on my lathe and mill and feel they are both worthwhile.

    That looks to be a very nice job that you have done on your lube/misting setup Bob. The photos illustrating it are excellent too, right up there with BTs and Metaliers photos as well, but tell me what is the PVC line in photo 3, is it for flood coolant, when that might be more appropriate for the particular workpiece involved?

    Ropetangler,
    Thanks for your kind remarks, BT has set us a high standard. You are right about the PVC line, that is my original system that works of the mills internal pump. I have a removable jet in the nozzle with a one millimeter dia hole for light work eg drilling and fly cutting etc for heavier cutting eg roughing out with a 20mm end mill or keyway cutting I remove the jet and use high volume supply to flood and wash away the chips.

    I have 3 off these that dad used often
    Dad had kero burners set up for his soldering..the hand ones he used when not in the shed.
    He didnt use metho for pre heat...he just poured a little kero into the circular bowl and placed a small bit of rag in it..lit that and away he went.

    If anyone's interested, there's an article in number 265 of MEW, on making replacement leather washers for the pressure pump for this type of unit.

    Sorry AJ, I forgot that we get new members on here. A very informative magazine, dealing mainly with Model Engineers Workshops, how to modify machinery, making cutting tools, a dividing head. They're what's in the current magazine.
    They don't do how to on models, just of the machinery that makes them.

    I made this 41.2mm OD die over the weekend. Using the part off insert as it is too hard for the HSS blank.

    Hi Kris,

    I'm impressed with your mist coolant system using ATF. I'm part way through setting up another mill (bridgeport clone) that has it's own coolant resevoir and pump. I was just going to use the usual coolant and be done with it but now you have got me interested in your setup. I have read about mist systems but never really got interested. What are the benefits of your system over the conventional coolant system?

    Hi Jack, nice work on the die. Nice finish. That radius turning tool looks nice and beefy, I like it!.

    Cheers

    Simon

    Kris's post on mist cooling has sent me down the rabbit hole as well.

    I found a on-line book with a couple of detailed pages about these systems that clarified a couple of concerns I had about them.
    The first one is "won't the whole shed become coated in lube"
    The way around this is, as Kris says, MQL (minimum quantity of lube and air). In factories where mist systems have been carefully designed and are in use the levels of lube vapour in the air and on surfaces is lower than those using flood cooling/lube resulting in cleaner workshops.

    The next thing is sure flood coolant will remove more heat than mist cooling.
    The trick here is that the mist needs to be directed directly onto the cutter tip and not generally flood the work.
    It's not suited to all aspects of metal machining but it appears to have any things going for it.

    Anyway FWIW here are some excerpts from the book. (sorry for the fuzzy text but the quality of the original was no better)

    Kris, I'd be interested in more details of the control valves and mixing chamber - did you build that all yourself?
    I'd also be interested in any references you came up with that discuss the process.

    I think it would be better to start up a new thread rather than clutter up this project thread with this topic.
