Nice work! How did you bore the interior hole? Drill press before the lathe? Is this CNC or manual?
I have the same issue on my motor except it's worse because the heat exchanger, raw water pump, and siphon break all have different hose sizes. I'm using the plastic barb adapters made by Marine East for now. You can also use a bronze coupling with pipe to hose adapters, but it's certainly nicer to have a single bronze piece to do the job.
Easy to make. I am using an old Southbend 9" "A" lathe from about 1947
Cut the broze rod stock to length. Chuck it up and turn one side to the major diameter of the barbs. FLip it and do the same for the other diameter. Spot drill the end, run a drill down the center, bore out the wide end and fair in a nice radius on each end. Cut the barbs, hit it with a piece of emery cloth in the to knock down the sharp edges.
I'll build you one for the cost of materials and shipping.
Shoot me the dimensions you need.
I like the one piece aspect. Should last forever now! Plastic pieces would really worry me and that hardware store brass always worried me.
WIll be interesting to see what the old brass one looks like when I swap it out.
Sounds good, thanks for the kind offer. If you don't already have the materials on hand, the industrial surplus yard near me has a variety of bronze rod and bar stock sold for $3 per pound. I could get the correct sized materials for the adapters I need and some send some extra material if you're interested. I think they have up to 1 1/2" stock.
Hamilton says the plastic adapters are rated for engine use, but I don't trust the plastic for long term reliability. They work fine for testing the motor and getting it running though.

Tell you what....
I will pay YOU to go get some of that material and shove as much of it as you can into a USPS box (IF IT FITS IT SHIPS) and pay your shipping.
And I'll make your part and ship it back to you!
That will save me a bunch of money on materials as we don't have anything like that around here!
OK, I'll go down there and take some photos so you can let me know what you're most interested in. Most of the material doesn't have the alloy marked, but some does. I know there are some nice pieces of aluminum bronze. I was thinking of using a few for new chain plates if I decide to replace mine.
Won't be able to fit much of anything in a small USPS box. If I remember correctly most of the stock is over 1 foot long. I already have some large USPS boxes that are the size for shipping board games, so they are long and skinny. That's probably your best bet. Weight limit for large USPS box is 70 lbs. Not sure if you want that much material, but you'll probably need the large box to fit the stock. I can do some cutting with my angle grinder if need be, but chopping it up to fit in a small or medium box would be a lot of cuts and the material would be less useful.
I think I'll be able to make it over to the industrial surplus yard tomorrow, so I'll take photos and we can go from there.
They also have nice 2 guage wire with good quality insulation if you're interested in that. I think it's silicone or another polymer that maintains flexibility a lot better than the PVC stuff. That's also $3 or $4/lb. I bought 30 feet for $20 or so that I used for battery and starter cables.
