    Well done Preso, I get around the adds buy paying the $15 a month for premium. I get no adds and I can download videos to watch later or when I don’t have service. It works well for me because I rarely watch commercial tv anymore and it’s cheaper and heaps better than Foxtel.

      Was going to say the same. Best $13/month I spend. Works out to about $0.10/hr of content for me. I pay $60/month for cable just so I can watch F1 lol. Preso, you might as well earn the $20 month youtube will pay you.

    Typing correction fluid makes a great resist for silver solder. It's pretty much liquid chalk, and whatever they use for a binder burns off cleanly in all the ones I've tried.

    Very interesting and well thought out thanks Mark. When I was bending copper bus bar for substations years ago we used a lot of oil on the tube. This made it easier and helped prevent creasing and kinking.

    If the little centering "fan" restricts airflow too much, just cut off every other blade (or more). You only really need three to hold the nozzle centered...

    • @ashleyward427
      @ashleyward427 Год назад +3

      I believe the primary use of the guide vanes is to mix air and fuel for better combustion and of course centre the nozzle.

    In addition to removing fins as others have suggested, you could make the center hole smaller and use the diameter of the threaded end of the nozzle to hold the swirl plate. Also, you might want to bend the lid handle closer to the furnace handle to get it further away from the exhaust hole in the lid.

    Came upon your videos when looking for help in making a small diesel aeroplane engine. I’m flying by the seat of ma pants for most of the specs but your video helped figure some stuff out, especially timing!
    Anyway I’m way up in the Canadian Arctic 20km south of the Arctic circle in a little place called Pangnirtung, Nunavut, Canada. South Baffin Island. Thought you might like to add that pin to your map. Just set up a Starlink satellite dish so we are super connected and I’m enjoying uncapped use of the internet! So I live on RUclips and in my workshop. I’m retired as well and a past teacher so enjoy the old nerd comments!

      Donald, I just checked out where you live on Google Maps. Man, you are remote! I noticed you had a Uqqurmiut Centre For Arts & Crafts. We bought a beautiful Inuit sculpture of a polar bear by Ashevik Adla when we were in Montreal a few years ago and we fell in love with the arts and crafts from Cape Dorset. We had no intention of buying the sculpture when we walked into the gallery but the very tall and very blonde and very sexy sounding French accented Roxanne soon won me over much to the disgust of my wife. However the sculpture made it back to Australia in pristine condition and it is much admired by guests to our home. We badly want to travel back to Canada for another holiday but with airfares so outrageously high at the moment it may have to wait. I love how you can zoom in forever on Nunavut and there is just nothing there. No roads, no settlements, just wilderness. I will definitely add your location to my map and thanks for getting in touch.

    Thank you most kindly for the lesson. The hardest part are the names and variation of components. example. a quarter turn tapered plug valve. the injector information and how to understand it's function, just excellent. I cannot use a lathe, more is the pity. But i have designed my own still, which i have prototype and debugged. Now i wish to build a full scale version 1000l and heating has been a problem. I have been looking at the diesel burners in alibaba, and they are just a perfect solution. knowing how they work was so essential, so thank you. The 340w blower gives off about 120kw. if you are interestd. i didn't know diesel had so much calorific energy. So you have confirmed for me the way to go, and.. how i should design the inlet ports. ❤

Of course, Olfoundryman is a legend but unfortunately, he is suffering from ill health and is finding it difficult to do any new videos of late. His back catalogue is a wealth of information though. He is actually a professional foundryman.

    Hi Mark,
    great work.
    consider having the oil line straight in the blower tube sticking out the end and the air delivery tube merging in a y junction.
    the air takes the bent path rather than the oil tube.
    In his way he oil tube can be pulled straight in or out from the leading edge as you wished

    • @Preso58
      @Preso58  Год назад +1

      I have seen that approach and it is how Perry Merrit made his burner. He had used car exhaust pipe which is thin enough to cut easily. The tube stock I am using has a 5mm wall thickness so it was going to be a mission to cut the opening to make the branch. If I had a tube notcher it would have been a piece of cake but sadly I don't own one. As it has turned out the fuel line assembly has turned out to be fairly easy. I have already run the burner inside the furnace and so far it is looking like a success. I'll put some pictures on my Instagram account.

    @hillonwheels8838 Год назад +6

    You may know this already but automotive voltage is technically not 12v. 12v is about the minimum voltage for starting the engine but should be 13 to 14.5 when the engine is running and is dependent on the state of charge of the vehicles battery and the load on the alternator. The lower the battery voltage or higher the load the closer the alternator will be to 14.5v so running the fuel pump at 12v you are not getting it's full potential where 14v would be the best in the long term. I also agree to keep the nozzle holder simple but this is your project and if we don't try new things we will never learn what works and what doesn't. Besides I'm just some random person in another country being a keyboard engineer enjoying you building something that I may want to make someday. Cheers

    • @Preso58
      @Preso58  Год назад +4

      Interestingly, I was running the fuel pump from a 0 to 30V DC power supply and I tried running the pump on voltages above 12V but it didn't seem to increase the fuel pressure or the RPM of the pump at all. That was a bit of a disappointment since I was hoping I could "overclock" the pump to get a better fuel flow from it. I know that I go over the top on some details of my builds sometimes but for me, that is what makes the project interesting. I like to try new procedures and even if they fail, they can be instructional just the same. I had to make a press tool for the new version of the swirl plate and although it was probably unnecessary, it was fun to see how closely I could get the punched hole to the size I needed to make it a press fit on the burner nozzle.

    Hi Mark, thanks for the shout-out, it is most appreciated.
    This is a great build. It looks like you have done a lot of research, and you explain the steps you are doing well. I did not expect that huge flame when you were testing the atomizer, but it does look like it will work well. The question is, do you know how much fuel will it use? Also, it is good to see the Hossfeld bender back on the bench and being used. I don't use my one much, but it is really handy when you need a nice bend in some tubing. I'm looking forward to Part 3.

    • @Preso58
      @Preso58  Год назад +1

      Thanks Jon. The nozzle is rated at 2.5 gallons per hour but that is dependent on the pressure of the fuel pump. I doubt that it will use anywhere near that much in my setup. I think the fuel pump is at maximum capacity now but it seems to provide enough fuel to match the capacity of the blower. I sent a viewer to your channel just yesterday. He was looking for a video series on building the Hossfeld clone and I didn't make any videos on that build. My bender doesn't get a lot of use either but for certain jobs it is a real winner. I do want to make up a set of dies for bending light gauge steel square tube though.

    It seems that burners made by myfordboy and VintageMachinery (with air from the blower coming in on the angle and all other tubes are straight) are simple as they do not require bending tubes and allow to position those tubes easily. Also, lid lifting 'upside down' mechanism (Olfoundryman) does not require using legs. 👍👍👍👍

    • @Preso58
      @Preso58  Год назад +1

      I did get the burner running today and with the nozzle guide vane in place to centralise the spray nozzle and the 3D printed cover it all worked as planned. I did consider the other style of burner with a branch for the blower but it's a bit of a mission to cut out the opening for the blower pipe to weld at an acute angle. When I was teaching Graphics we would draw the developments of those branches so they could be cut and formed. If the metal starts out flat it's not too hard but cutting the correct shaped opening in heavy wall pipe means plasma cutting at some intricate angles.

    Hi Preso, excellent video and series so far.
    The fuel pump works fine stationary but when there's forced air coming through and you get the 'venturi effect' I think thats when the pump will have trouble supplying enough flow rate.
    Will be interesting to see and looking forward to the next episode.

      I did light up the burner today but it was just running on the bench. The flame is stable but there is a lot of smoke. I think that once it is operating inside the hot furnace I will get better combustion. It would be nice to have some extra capacity in the fuel pump but that's something that will be easy to upgrade.

    Hi Mark.
    Why not make some kind of bracket that will allow you to use propane and diesel burner without a need to rotate furnace?
    I do not think it's too complicated. Just bit bigger tube, so diesel burner fit nicely inside, cut on one side so fuel line can pass, and some kind of sleave on gas burner so it also can fit inside it.
    That way, you can quickly preheat furnace with propane, and do a quick switch to diesel.

    • @Preso58
      @Preso58  Год назад +1

      Yes, that would work. Preliminary tests today show that the burner will light up on the bench and the flame is stable. Next test is inside the furnace.

    Hi Preso, Another top video. I made a similar burner (not your design) and it created a really beaut flame. I used heating oil in mine, you might like to give it a try. If you can't get it I believe it's half diesel and kero mix and gives a cleaner blue flame. Apparently straight diesel burns a bit sooty.

    • @Preso58
      @Preso58  Год назад +1

      I am still keen to try adding kerosene but I have had some bad experiences with kerosene deteriorating plastic parts. I used to keep kerosene in one of those trigger pump bottles but they never lasted long. There is not a lot of heating oil used up here in the subtropics but diesel is surprisingly cheap at the moment. At one point it was more expensive than unleaded petrol but now it's gone the other way.

    • @Preso58

      I know! it surprised me too. I guess the spray pattern is "scalable". It won't deliver the same amount of fuel that it is capable of but it is producing sufficient atomisation to burn in a smaller volume.

    Just for information, I did a melt today with my Kerosene burner. Melted about a litre of aluminium, and used about 2 litres of fuel. I’m using a central heating burner. No idea how that compares to propane use though!

    • @Preso58

      Kerosene is a bit harder to buy in bulk here. Some places in cooler climates (Melbourne and Adelaide) sell it as home heating fuel but even at $2 per litre, diesel is still probably cheaper than LPG.

    bye the way fist number on side of nozzle is flow rate as you know and flow rate is tested at 100 psi if pressure going to nozzle is less or greater then that it will increase or decrease flow rate some comercial burners go as high as 300 psi wich meanes want see burn rate on nozzle an lookup 300 psi for true burn rate also higher supply pressures will attomize fuil better

    • @Preso58
      @Preso58  Год назад

      It is a garage and I have to share it with two cars. I recently got into trouble for depositing metal dust on my wife's Subaru Impreza. Of course it is white and the dust showed up as red ferric oxide speckles all over the paint after it rained. I am now on a good behaviour bond and I have to reverse the Subaru out of the garage if I am doing anything like grinding or cutting steel. I don't afford the same luxury to my 13 year old Camry! One day I may do a shop tour but that would mean having to clean it up.
      I have built a sort of annexe onto the back of the garage which is now my wood shop. The main shed is 9M X 7.5M and the annexe is about 6M X 2.4M. I also have a 20 foot shipping container which is used as overflow storage and a home for my sheet metal guillotine and big horizontal bandsaw.

      I did make a tube bending die for a Hossfeld bender clone. It works fine on thin walled ERW tubing. I have also made cast aluminium accessories for my lathe and milling machine. Having the capability to make castings allows for shapes and forms that would be hard to replicate using fabrication techniques.

    With the guide "fan" to centre the nozzle tip, you only need 4 or 6 points (or blades) so as to keep it small and not cause turbulence. In other words, cut off at least half the blades.

    Motors designed to run at fixed DC may work with PWM but you are likely running it in a lower efficiency state which may shorten the life of the motor. You may want to use a pump that is designed to run variable speed. Cheers!

    • @Preso58
      @Preso58  Год назад +1

      The pump only runs at low speed during the start up phase. Once the heat stabilises, the pump is running at pretty much at full voltage. Given that I only use the foundry about 8 times a year I think it will be OK. However, I am still open to the idea of using an alternate style of pump. This configuration is really a starting point for experimentation.

  • @tomweinstein

    Rather than controlling the pump to reduce the flow, have you considered running it full speed, but having a return line back to the tank with a restrictor valve?

    • @Preso58
      @Preso58  Год назад +1

      I did consider that but the PWM controller works perfectly. I can run the pump at idle and it barely pumps anything and it will smoothly increase the flow up to full capacity. I was surprised it worked so well. I built a PWM fuel pump for my jet engine and it wouldn't let the pump idle at all. It would always start at about 30% which was a bit scary when the engine was cold. Usually lots of flames and a red hot tail pipe until it settled down.

    I would think that once you silver solder the tube to your cap, that would be sufficient to keep the nozzle in a fix position, no? As far as ads, I don't really mind them. I will say this, I don't know why you are letting Google take all the ad money off your hard work. There's no reason NOT to join the partner program and get your share.

      With regards to the advertising and the partner programme, I am just being stubborn. If I do finally give in and sign up I think the best solution would be to donate the income to a charity. The fuel tube will position the burner nozzle once it is silver soldered to the cover plate, I am just adding an extra constraint to be sure that radiant heat doesn't soften the tube and allow it to sag. I have it on good authority that a 3D printed swirl plate was totally unaffected by the heat of the furnace. It seems incredible but maybe the blower velocity keeps the heat out of the burner tube.
