  1. I know your working on the cooling end of things right now but i was thinking about this project earlier when i was doing some wiring and had to ask, are you planning on useing cloth covered wire for it?

    You bet. I've got some rolls left over from a previous build but I may need a few more colors and some heavy gauge wire for the starter.

    I'd like too. That would be awesome. How can I do that? I dislike that asphalt covered loom they sell. I don't think it's period for 1923 either.

    Just a wild ass guess, but any chance that radiator uses the same fitting size as the old fire hose nozzles used..

    Hi Jerry,

    Been following your build for a while, looks great!

    I looked up your thread specs in my engineering handbook and there is a listing for an American Standard Straight Pipe thread, 2 in. nominal dia. and 11.5 tpi.

    Pitch diameter 2.3044
    Minor diameter 2.219

    Sound about right?

    There's a chance. I looked on ebay where's there's lots of fire hose fittings for sale but I found no way of knowing the sizes unless I email everyone.

    I looked up some charts on American Standard Straight Pipe Thread on the net and here's what they listed:
    <table class="large" id="table1" border="1" width="100%"><tbody><tr><td>2</td> <td>11.5</td> <td>2.375</td></tr></tbody></table>nominal Thread Actual size

    I couldn't even find a source for ASSPT anyway. So I've decided to open up a 1.5 inch coupling (actual size 1.9") and screw it on the existing outlet then screw an elbow into the coupling. I've just got to find a brass coupling at a reasonable price.

    Fan pulley

    While I was contemplating the radiator problems I started working on the fan pulley. It had some pretty big rust holes in it. Luckily the pulley was made from two sheet metal discs riveted to a cast iron hub. I drilled out the rivets and bead blasted everything. A jig on the bandsaw (consisting of a hole and a 3/16 screw) got me two discs. Then, one at a time, I bolted the pulley halves to the hub and pressed them into a shape. The shape wasn't too good so I chucked the assembled pulley into the lathe and applied a little brute force with a steel bar. That trued the halves up. Today I've got to open up the pulley a little more. The vee belt is one inch at its widest. I haven't started look for it yet.

    Jerry,

    The 1911 Cadillac used a link belt for the fan belt. This is available at industrial suppliers in various widths. I am looking for 1/2" in black; the local suppliers have it in red, yellow, green but not black.

    On your wire lacing: I have done it on several early cars & some aircraft work. It is easy to do & the waxed cord that you use in a leather sewing awl is just about right. I have found the method used on some original English cars - good idea there since it lets the smoke out better!?

    What are the dimensions of the thread you actually have?

    The "nominal" dia is pretty much useless.

    Measure the OD of the thread crests, the OD of the thread roots, the TPI, and estimate the profile angle (IE make sure it's really a 60 deg thread).

    My table of National Fire Hose threads shows nothing in the nominal 2" category, and nothing with a TPI of 11.5, so that's probably out.

    I own a lot of thread tables though, so with some good dimensions, I might be able to track it down.

    Ha ha. I know what you mean about letting out the smoke! Another friend suggested a link belt. He said you could get them up to 1 inch. I'm researching that tonight. On my '14 REO, since the horn wires were exposed I wrapped them in cord and varnished them. It had a period look and that's good.

    Threads

    Neil, a buddy of mine, came over this afternoon to give me his two farthings worth on the matter of the radiator outlet and the threads. Neil grew up in Scotland. His father was the gamekeeper at the Balintore Estate in Angus (county.) Balintore is a large castle that even in Neil's youth had fallen into ruin but is now even worse. In fact, a guy just bought the place for around 200K US. Quite a deal if you're into castle restoration. I can't imagine how much fun it was for Neil and his brother to have the run of the place. Anyway, Neil went on to become a ship's engineer and worked on many a mighty ship's engine. He took one look at one look at the radiator outlet and said. "Are ye daft, man! Just grind off the threads and slide on a hose with a clamp." After all my talk about saving the threads the man has a point. What do you think?

    More pictures of Balintore. http://derelictionaddiction.fotopic.net/c1672266.html <input id="gwProxy" type="hidden"><!--Session data--><input onclick="jsCall();" id="jsProxy" type="hidden"><input id="gwProxy" type="hidden"><!--Session data--><input onclick="jsCall();" id="jsProxy" type="hidden">

    In a past life I worked for a compressor package fabricator. One progect a nitrogen generator needed British standard threads on the final connection. British standard threads are NPT without the taper. Local machine shop took a few pieces from us and recut the piece without a taper.

    That's what I was going to say. ;) Unlike Neal, I didn't grow up around a castle in Scotland as the gamekeepers son, but I DID grow up near Kalamazoo, MI, the son of the "gamekeeper" and manager of a "gentlemans estate" here. The owner was one of the Upjhons, of pharmacutical fame. We raised pheasants, had a kennel of Labs ( had a bitch from the Queens Kennels) and German Shorthairs. I thought everybody shot skeet, played tennis and hunted pheasants in their free time.

    Agreed.

    You gotta know which battles to fight and which to walk away from.

    This is a one of those instances, I think, where you're better off to just go for the expedient fix and move on.

    It's not like using a hose and clamp there is going to somehow compromise the cooling system.
     
  18. i wouldnt just cut them off, maybe file them down leave a single ridge to hang onto the radiator hose

    The other good thing is that you can't see it unless you lay on your back under the radiator.

    You two would have a lot to talk about. They did a lot of grouse "hunting" at Balintore. In fact, I think they shot almost every last one of those suckers.

    Cooling

    I did manage to get something done today and that was gaskets. The two water manifolds need a total of 24 gaskets. I chose cork as the gasket material. Not that I'm really fond of cork. It can get oozy and crumbly. But the surfaces on the iron cylinders are a bit corroded and uneven so I think I need something a bit more compressible than paper. I'll smooth on a thin candy coating of Permatex Ultragrey (my favorite gasket compound) just to help out.
    To ensure all the gaskets were uniform I made a template from an old milk jug. A ruined hole saw makes a dandy gasket punch if you sharpen it real good. For the small holes I used a hole punch I inherited from dear old dad. Then, with the drill press acting as an arbor press, I punched up 16 gaskets before I had to leave to pick up the kids from their first day back at school since the snow started. Maybe tomorrow I can get the water manifolds on. The last picture shows the fan setup. The fan is driven off the gear that drives the intake cam.

    We probably would! We didn't shoot grouse, but we did raise some "Chucker" Partridge to use as target practice. Seems sort of barbaric now, but we thought it good sport back then. Trapped pigeons in the barns on the place to blast as well. Pheasants were good sport a few days after an official "hunt" (for the owers rich cronies) with my own dog and my favorite 20 ga. pump. For the thousands we released, there are precious few around here 30 years later.

    I remember being given a glass of whiskey in the hunting lodge one day after a hunt when I was about 13. It was AWFUL, and I've tried since, but never been able to drink whisky or Scotch to this day.

    I believe Neil told me a similar story about a youthful dram-o-scotch after the hunt. But judging by his behavior since, that incident only whet his appetite for more. :)

    Are you past the radiator fitting dilemma yet? I can appreciate the comments you made in an earlier post stating that you don't want to cut the original rad in case some future restorer needs it uncut.

    This might work. Fill the threads with gasket maker. Cut a collar with the correct ID and split it. Affix the collar behind the fitting with gasket maker. Now affix a rubber hose. Totally reversible, will not leak and will not require hours of fiddly work.

    The dilemma is over! The threads are gone. A fan belt is on the way. Tomorrow I paint the fan and assorted pulleys. I predict full radiator and engine function by Monday. Thanks to you guys for all the suggestions.

    Hey plym, I think you just nailed it. From all the posts, i swear that Jerry brushes his teeth with permatex ultra grey :)
    But seriously, what's the worst that could happen. Not going to cause any damage. No heat and no cutting

    Nice, impromptu hose barb.

    That's usin' your noodle.

    Gonna be damned near impossible to get the hose off later (without cutting it), but it'll for sure not come off on its own. :D
