    My Flat Head Hit Miss Engine

    What method did you use for making the piston rings? Yours obviously work very well.

    My Flat Head Hit Miss Engine

    If you had a sawzall around one of the long blades would do the trick with a lot less wear and tear on the arm. Engine is looking great ! Very nice work.

    Searching for a really good book on TIG welding

    Keep watching, its warm inside ! Taking a few notes is a good idea too, just like in the old school days. Having those notes to refer to when you do go in the garage to practice will help progress.

    Searching for a really good book on TIG welding

    Even with being educated on all the proper techniques the need for lots of practice cannot be over emphasized. I had did a little TIG and that was many years before I bought my new rig a couple years ago. When I got it my first tries were just as ugly as what Brian is experiencing. I...

    Searching for a really good book on TIG welding

    Brain has been pretty quiet about the suggestions. I wonder if he found a book he likes or watched any of the recommended videos?

    I agree but he already has/bought the inverter TIG. He also needs AC as he does aluminum.

    Searching for a really good book on TIG welding

    Beware of older books on the subject. Inverter TIG welders are a fairly new breed (which Brian has), the older books were covering transformer based machines. There are quite a few differences, for example AC frequency, that was not adjustable on old transformer machines. Inverter vs...

    Time for a new Horizontal Hit and Miss engine

    How many RPM's is that in the latest video?

    Time for a new Horizontal Hit and Miss engine

    Here is a hinge knuckle I made for my skid steer. Its 5 pieces total. The largest section is 1-1/2 inches thick. With preheat I did it at about 150amps. Without preheat not a prayer.

    Deep V grooves with a gap are standard practice TIG welding pipe. Even the best pro tig welder couldn't have done that piece without preheating using a welder limited to 200 amps max.

    Rough rule of thumb is 1 amp for each thousandth of material thickness without preheating. With a TIG like you have preheating a piece like that is mandatory. If you don't preheat the aluminum will just absorb the heat applied and not puddle until the entire piece is near melting point...

    The excellent suggestions given suggest removing material inboard of the pivot pin, not necessarily adding, making taller etc. It could be a simple fix that would only take a few minutes to machine away some material and try.

    Time for a new Horizontal Hit and Miss engine

    a quick search found this recipe on a steel manufacturers site for annealing O1 steel. Sounds like the proposed torch method may still leave it quite hard. Annealing Annealing must be performed after hot working and before re-hardening. Heat at a rate not exceeding 400°F per hour...

    Still going to try and get it running slower like the typical hit/miss engines ?

    Time for a new Horizontal Hit and Miss engine

    In the video it appears you are now using the commercial carb and have a throttle lever. Will the engine slow down at all? Its running well but awful fast for a hit miss engine.

    Considering the carb has no throttle plate to adjust rpm's it sounds like you need to make a reducer bushing for it to accomplish the same function. Pretty easy to try.

    Why a M10 die? Do you not thread at all on your lathe?

    Time for a new Horizontal Hit and Miss engine

    Probably not in this case, but I will mention it anyways. Another pretty common problem is the wrong gas, welding suppliers have been known to occasionally mislabel a tank. 75/25 blend intended of MIG really raises hell if used on a TIG for some reason. Brian stated he was burning...

    Time for a new Horizontal Hit and Miss engine

    2% lanthanated electrodes work extremely well for both aluminum and steels, 3/32 size for general purpose. It is the go-to electrode for most TIG welding. The other thing is to be sure and remember to switch to AC for aluminum and DC for steel. I have forgot on more than one occasion and...

    Can't find any fault with the blade you use or how you use it. Its the same blade I use.
