  1. matching pump and cylinder pressures

    Thanks for the info, I (sort of) understand that you on get the top of your power curve when the (in my case) air over hydraulic jack makes contact with the steel and is (for lack of a better term) straining against the top die.
  2. Getting my "T-Burner" tuned

    BM and Frosty, I think I have it up too high and am wasting gas at this point. I think I can get it as low at 5 to 10 PSI before it starts sounding like a V-1 Buzzbomb. I can always take the bell off and see what that does as well. thanks Ernest
  3. Getting my "T-Burner" tuned

    Good Evening from Sunny but not warm Alabama. I have installed my 1" T-Burner in what I call the forge with a face only a mother could love. These images are using a .045 ( I think) MIG tip at around 20 psi with a 1" pipe and 1 1/4" bell on the end. To my not-very-good-at-judging-this-eye the blue cone looks less solid then an oxidizing flame and maybe between oxidizing and neutral. Please let me know what you think since I am rubbish at trying to figure this out for my self. Ernest
  4. That makes me think of the truck crash in the Matrix and the use of thermite to weld RR track. I know thermite is not an explosive so I guess it would fall under fire. Ernest
  5. matching pump and cylinder pressures

    Yup, reminds me of a quote "They say when you've drawn blood - you're exfoliated". The very last thing anyone in life wants would be a jet of VERY hot oil shooting out from a hose. I was thinking about the stroke length and I had a question. Is there any efficiency to be gained by using a shorter stroke ram since in most cases the steel will only move a 1/4" or so per-stroke. I assume that you need enough fluid in the reservoir space to complete the longest stroke but I did not know if this 8" cylinder starting from 6.5" extended (for example) and pushing to 7.5" (again for example) is any more or less efficient than a short ram (say 2" max) going from 0" extended (again again for example) to 1" extended. I know that I don't know so if I am typing nonsense please let me know and I will not take it hard. Ernest
  6. Anvil heater

    Michael took the words out of my mouth. the small tank can only get and store so much heat from the sun on a clear day. An external 250 or 500 gal tank (external meaning not covered by a roof or the like) has a much larger surface area to collect sunlight on a clear day and much more mass to hold that energy for later.

    I just found out that Mr. Propane will not come out to play when it is 22 degrees outside without a heat source. I can honestly say this is a first for me. Ernest (the cold)

    Keep on keeping on and make some neat things. You would be amazed at what you can come up with. Ernest
  9. Horizontal/Vert or Porta Bandsaw

    A buddy of mine has this one Grizzly G0622 - 4" x 6" Metal-Cutting Bandsaw and he can use it as a 90 degree Vertical Cutting or for Horizontal Cutting and he seems to like it. I have a HF portaband and I don't like some of the changes that they have made since adopting the Bauer name but it works well enough.

    I have to wonder how many different times the word dog shows up not talking about something with 4 legs and a tail. This is from Wikipedia so take it for what it is worth. In engineering, a dog is a tool or part of a tool that prevents movement or imparts movement by offering physical obstruction or engagement of some kind. It may hold another object in place by blocking it, clamping it, or otherwise obstructing its movement. Or it may couple various parts together so that they move in unison – the primary example of this being a flexible drive to mate two shafts in order to transmit torque. Some devices use dog clutches to lock together two spinning components. In a manual transmission, the dog clutches, or "dogs" lock the selected gear to the shaft it rotates on. Unless the dog is engaged, the gear will simply freewheel on the shaft. This word usage is a metaphor derived from the idea of a dog (animal) biting and holding on, the "dog" name derived from the basic idea of how a dog jaw locks on, by the movement of the jaw, or by the presence of many teeth. In engineering the "dog" device has some special engineering work when making it – it is not a simple part to make as it is not a simple bar or pipe, and the metal used in its construction is likely to be special rather than regular steel. There is potential for confusion as "dog tensioners" are levers that are named due to the shape of the lever appearing as a dog leg, as the lever is in a pantograph arrangement, or "dog trailers", which are named due to the use of multiple trailers for transporting animal cages.

    For the most part I am familiar with how they are mounted, the sliding tab is going to take some work. I remember using this type of vise in school where the tab would be used for (I think) over sized stock. Other than that I would need to RTFM (read the fine manual). That I do remember and the ones used in school were "well used" enough that we would use new scrap wood as a second buffer. I don't think I will make a new jaw, Acme Screw in the hand is worth 2 at the scrap yard, but I do think I will do something to add on to the broken part to make it more usable. Thanks for all the info guys. Everyone in Alabama, stay warm because it will be very cold this weekend down to the teens. Or as Frosty might call it T-Shirt weather. Ernest

    Saved this from the scrap yard last week and have used it at least 5 times since the 24th. I wonder if the plates on the vise are cast iron or steel. If they are cast iron I might try and brazes something on the broken plate. Ernest

    Fatfudd, I think I get it now. So that would mean you would have to leave it on the press until it is squeezing for all it is worth and at the same time watch all your heat get sucked out by the top and bottom dies. So this sounds like a problem of efficiency. If you were pressing using just the air you might get a unit of force we can call 10 Units Of Smash (UOS) at a give speed. But since you are using the air to drive the hydraulic action you might get 10 UOS less any overhead lost due to friction and at lower speed. If you had a pump moving a hydraulic cylinder you might get the same number of UOS BUT at a greater speed. What I am building requires a compressor motor to compress air, the air to power a hydraulic pump the pump to move the jack BUT when you have a motor directly moving the hydraulic pump you remove that extra overhead. If I am not making any sense you are welcome to tell me and I will not take it hard since I know I know very little about this subject. Ernest
  14. First knife - not yet hand sanded

    David, Did that start out life as a axle or drive shaft? Looking at the pommel of the knife reminds me of the end of drive shaft or axle. Good looking bit of work and I know it has a vestige only a mother could love but I like the Mad Max look of it. **************Starting Rant Mode Now******************* In Alabama my CCW permit will allow my to have a 500 SW revolver concealed on my person but not a knife! They can't take the chance in Alabama that a CCW holder will have *GASP* a Bowie knife concealed on their person! They my stab someone right next to them. A revolver that Frosty might use to level the playing field with a bear is much safer! •Bowies and things that are like Bowies are illegal if concealed. •Bowies are illegal to have in your vehicle. •A machete might be classified as a Bowie and it would be illegal if you carry it concealed. •A 11″ butcher knife has be found to be like a Bowie in court so don’t plan on using it in a crime. •Selling Bowies to people under 18 is illegal. Except as otherwise provided in this Code, a person who carries concealed about his person a bowie knife or knife or instrument of like kind or description or a pistol or firearm of any other kind or an air gun shall, on conviction, be fined not less than $50.00 nor more than $500.00, and may also be imprisoned in the county jail or sentenced to hard labor for the county for not more than six months. Why Alabama will not add 11" knives to the CCW is beyond me but given the fines and punishments I bet this is a law that has not been updated in a long while. **************Ending Rant Mode Now*************************************

    I don't know enough about the hydraulics to understand this statement. Would this mean when the jack is fully extended? The log splitter option is on my list of things to look for, have you posted a photo of your splitter/press? I want to make a proper hydraulic press but I am limited in funds, space and voltage right now. I am willing to start small but I am trying to build my press so I can change out the jack for a hydraulic cylinder down the road. Ernest
