    Antique homebrew HOBART MR-300 with a flathead 6

    Hobart 300 welder with a flathead 6, home brew combo! Coming home soon! Worst case scenario she's a parts machine.
    Was welding when parked around 20 years ago.

    Looks like Chrysler industrial engine. If it is, there are four choices:
    216 was used in WWII vintage Dodge military trucks.
    230 was used in the Dodge Power wagon introduced in 1945, used till 1960. It was prone to cracked block & head gasket fails as first two & last two cylinders were too close.
    236 was used in many welders, air compressors, and low production farm tractors.
    251 was in later Power Wagons.

    236 & 251 were two inches longer making room for more iron between 1-2 & 5-6 bores.

    Parts are still available. I overhauled a 236 years ago stuck from sitting, and had a 230 rebuilt fully later. My block was cracked. I eventually found a rebuildable block in a cement mixer. It now powers my Power Wagon.

    Flat head Ford V-8. My old Hobart homebuilt had a Chrysler IND 251. Had to steal an updraft manifold off an old combine and make a U shaped adaptor to fit the updraft carb but it worked good. One of theose things I should ahve taken some pics. of. Those old Hobarts were good welders.

    Fake? If I went to all that trouble of mounting a blower it would be a real one.

    Even better

    Had a buddy at an exhaust shop that built a Buick heat racer for the demolition derby years back that built his own vertical zoomies with 8 individual tiny glasspacks, It sounded pretty good... To me anyway.

    Great photo quality - Pls post more pics - when you, 'get it out
    of the weeds'.


    This a high-example of deep-farm Canada [ana?]. Think, of all
    the work [someones] Granddad did with this machine, to save
    money, in the struggle to pay off the Wheat Ranch.

    If this were 'my trophy' - I would strive to make the engine and
    welder cooperate [make a spark]. Do nothing to the externals,
    with the exception: of a period [farmer] gage console, and show
    at vintage farm equipment events . . .

    hth


    Opus



    ps -

    'Hobart the Welder' - may be solid with Mud Dabber Condos - if
    this is the case - still show it, as is, without 'Spark' . . .

    Worst case scenario! I went 230 to keep my truck correct. I console myself that it isn't numbers matching, many got replacement blocks under warranty. My truck was under 30,000 when it received its third engine.

    The stencilling in the frame says Rumely ?

    If that's related to Rumely tractors, that's pretty cool too.

    I'd look at keeping that instead of paintin g over it

    I thought the same thought. The frame is the same channel as Rumley tractor, but nobody would cut up a Rumley tractor for this purpose...........would they?

    You know, I think they did!

    ** Engine is 1946-1948 Dodge 230 c.i. from a car.
    ** Frame is from a 1931 or older Advance-Rumley Oil Pull tractor
    ** Radiator is from a 1949-1950 Oldsmobile

    I won't paint anything.

    Will update details as I research it more.
