  1. Tom, I am interested. Can you send a few pictures to my email, and confirm the threads size to be the magic 3.125"-16 UN? My email: Thanks!
  2. Molasses and Gray Cast Iron - WARNING

    I think electrolytic is better in that sense. It will only remove rust, not the conductive material. An balance the solution pH level yes.
  3. Molasses and Gray Cast Iron - WARNING

    That is how soft it gets. The thing is that for molasses, when the rust is gone, the active part of the molasses will continue processing the iron. For regular iron parts, the material loss is fairly limited. For gray cast iron, the molasses will remove the iron structure in the surface of the parts, leaving only the non-corrosive elements of the cast iron, which are soft and brittle. I will assume the same process was initiated with the ZEP industrial rust remover. I lesson learned indeed.
  4. Equipped with my big IBC container (260 gallon) converted for molasses rust removal, I have done several rust strip batches of various rusted truck parts. With a 1:10 molasses/water mixture, soak time has been 2-3 weeks heated to 100 degrees F. I have noticed that regular cast iron get very clean, but may loose the smooth surface finish. The same goes for regular steel. Machined surfaces maintain a smooth appearance. The big mistake and a even bigger jump in my learning curve came today; picking up the last batch consisting of rare/hard to find parts for my 1935 Studebaker truck build. The clutch housing and the water pump housing was obviously casted in the popular gray cast iron. Despite being popular among automotive design engineers, the material do not react very well with molasses.... Big mistake! Graphitic Corrosion in Grey Cast Iron is the terminology. Approximately a 1/32" thickness of the normally solid material hits a weak spot; getting soft and very much like the graphite of your pencil. You can scrape the surface of the casting, and it will leave a new harder surface beneath. All details like machined surfaces gets wobbly or flaking, and once cleaned up, the details are gone (at least the tight tolerances). Fine threads are gone too. I will be able to save the clutch housing, even if it means to re-surface the mating surfaces. The water pump....not really sure, I may need to re-manufacture some details as a minimum.... A tough lesson learned..... Mechanical rust removal, OK. Chemical rust removal, a completely different ballgame.
  5. That is correct. While the design is very much the same, the trucks used a larger thread base due to the larger bearing cups size. I have seen re-manufactured caps, unfortunately not for sale, but installed on a few trucks. The original material is fairly soft aluminium, great for durability, not very great due to the softness. They did or do tend to slip the threads....
  6. Bumping this up. Still interested.
  7. I have spoken with Bill, a very nice gentleman, we had a long talk. His 2T2 and 2M2 is very interesting trucks, but he do not have what I am looking for. Unfortunately. Thank you for leading me to this Studebaker and Diamond T resource, we had actually many common friends :-)
  8. Thank you, I will give Bill a call :-)
  9. Thanks, I will update the add :-) Robert
  10. I bump this up. Thanks :-)
  11. Parts from a stude estate sale.

    Any Delco Remy starters? A 718V for a 1931 standard six or similar would be great. Thanks!
  12. In search for a Delco Remy 718V starter. Used to my knowledge on several engines/models (list not limited to the below): 1931 Studebaker Model 54 (Six) 1935 Studebaker 1T2 truck Characteristics: 6V, 3 bolt mounting flange, drive housing 1836217, drive pinion 2A-5112, switch 1838644... PM me if you have one. Thanks! Robert
  13. I am in search of vintage gauges (4) identical to the below setup (Speedometer, gas, temp and combo amps/oil). Please note the style of the arrows/indicators. Was used by Studebaker among others. Anyone with a set available....? Appreciate any leads, thanks! Bob
  14. Was also used on 1931 Studebaker Model 54.... And on the eights in the same periode.
  15. Robert, I appreciate your assistance, please let me know once you are up and running again. You can communicate direct with me on Thanks! Bobby
