Stude Light

Dalton made lathes very similar to the South Bend. My Nine by Four Dalton has been a really nice piece of equipment that I've use many times making parts for restoration projects. This one had some surface rust when I got it but cleaned up nicely - WD40, steel wool and plenty of elbow grease (and time), but was a fun project in itself. Here is a pre and post restoration of a lathe in a condition similar to yours

Nice find. You'll have fun with it. This is an extremely helpful forum: http://www.owwm.org/viewforum.php?f=77&sid=946d4fd390c659441a01daf8455dad26 Scott

08054 is a New Jersey zip code

Vinsetta Garage in Berkeley, MI (suburb of Detroit) dates back to 1919 It is now a restaurant but kept most of the charm of the original facade and an interesting vintage automotive interior

Yeah, that's a project alright. 1923 Light Six with some really interesting headlamps.

1920-1923 Big Six and Special Six

The Wagner K96 was used on the Special Six and Big Six 1923 and prior. I'll look in my other book tomorrow to see how far back. Scott

Yikes! Good to hear though that he is doing well, post surgery. I'll add him to my prayer list. Scott

Knocking usually is a bearing or piston pin. One thing you might try is just grounding one plug at a time and see if the knock changes tone or intensity. If so, you'll know what cylinder it is. If not, it may be something else. Scott

Todd, One thing that I always notice on flare fittings is the flare nut used. Pictured is what you typically find in the hardware store on the left, an original 20s nut in the center and something I found on eBay on the right. I was also able to find nuts shaped liked the one on the left but as tall as the others so I turned it down on the lathe to look like the center one. It sounds as though I'm a bit like Mr. Harwood as I turned down the one on the right to get an exact match to the center one (hey, I like things to be right and it wasn't slender enough in the middle).

1920-22 was a 3 ring piston with an 11/16" piston pin and unbushed. Then sometime in 1922 they switched to a 4 ring piston with a bushed pin. In 1924 they changed to a larger diameter (7/8") piston pin. Wonder if the larger pin design maybe created a problem? Interesting that Egge had the larger pin piston but not the smaller. This could probably fixed with a thicker wall bushing. Regardless, need to find Dave an engine. I know there is a spare engine out there, we just need to find it.

Thanks for the info. I'm not terribly worried as I fully inspected the pistons when rebuilding but I will consider replacing them when I have the time to take the car down. I did have two other sets of cast iron pistons from other Light Six engines. One was like my originals (from a 1922) and looked fine but the other set were different (1924) and several had cracks. I do know where several 1920-mid 23 blocks are but shipping from Australia will be expensive. Scott

What kind of speeds were you two typically pushing your cars too? Kinda makes me think about replacing my original cast iron pistons although the pistons were not the weak link during a competitive 25,000 mile durability test run by General Motors Research on a 1922 Light Six.

Dave, If you don't come up with a complete engine I have a Wagner starter, generator and distributor if needed. My spare 1924 block went to Europe two years ago and is running in a car now. I'll keep my eyes open for one but you may need to buy a car to get one. https://www.hemmings.com/classifieds/cars-for-sale/studebaker/light-six/2147674.html Scott

There were two versions of the OS-1. The one pictured by the OP is the earlier version and came on the Velie 34, Climber S-6 and on the 1920-1922 Studebaker Light Six EJ. I'm not sure if the change came sometime in 1922 or just for the early 1923 Light Six EM models (before changing to the cast iron head). I believe that many of the parts interchange between the two versions (jets, gaskets, float and such) but there are definitely some porting changes and another circuit added. Photo of later model is below. Scott
