As stated before you should think of making things as a bit of a chess game. You have to think ahead. Sometimes perfect scale is cast aside to utilize what can be easily done. Here a round nose end mill has been used to machine a curved bottomed slot between the bits of round stock. I knew I had both 1/8" and also a 3/32" round nose end mill. The 1/8" mill was too big. The 3/32" end mill was just right. I don't really care what perfect scale distance between them is. So the drilled tubes were placed .093 apart when the holes were drilled. Get R' Done!. The milled shoulder is to stop the square head of the bolts from spinning.

Now it's time to slice them off. Which I didn't get a photo of. Sometimes I get on a roll and forget to get some snappies. But here the angle vise is being used to bevel the bottom where they will be soldered to the hose clamps.

I had to have a way of positioning these little bosses on the hose clamps so some hollow spacers were made up. #0-80 screws will be used with these hollow spacers to hold the parts when soldering.

Here the spacers and bolts are holding the dogs, and gravity is holding things in place on the hose clamps where they will be soldered. I have found gravity to be a pretty dependable resource.

I wanted the bolts to be right down close to the clamps. Here the gap between the bolts and clamp is too great

Here the parts have been dis assembled and put back in the angle vise. A little more material was milled off and things are looking good. almost no gap between the bolts and clamp. I actually did this several times to get things just right. I has several hours of work invested in these little guys and I didn't want to goof them up. Remember, put it together, take it apart, put it together....

Here is our little gaggle of bits and pieces. I was hoping to finish up the Okadee connector today and start on the mold but we had this crazy thunderstorm here this morning. It started about 5AM. and went until almost noon. I really enjoyed the storm. It rained an inch and a half. Problem was, the electricity was off all day. Oh well, nice day for a nap :D

Hello My Friends
Why thank you RussN. Patience...as I often say go with what you got. In my case it's perhaps more stubbornness than patience :wink: I'll gladly accept the compliment though. The Okadee connector masters are now complete and mold making can start. Here are a few snappies.
In these photos the bosses for the clamp bolts are being tinned with soft solder. A pointed steel rod had the end bent to hold the surface being tinned level for tinning. It was fluxed and some small pieces of solder were placed on it.

Here it is after tinning.

Here is the set up for soldering on the bosses. The main part was held in a small vise, and frogs were used to hold the bosses in place.

Careful use of solder was necessary so as not to solder the bolts and spacers together, which are only used here for positioning. Also the flux pen was used to apply flux only where soldering was wanted. Heat was evenly applied and the solder slurped right into place. It's surprising how little solder is needed for most jobs.

Here are the hose clamps after the bosses have been soldered on. Notice the flange on the inside of the clamps. This fits over another flange on the outside of the hose barb.

In this photo you can see how the flange on the clamp fits over the flange on the barb.

And now some photos of the finished masters. The T bolt is not threaded yet as this is just a master as threads do not cast well. The castings will be threaded #3-56 when on hand, and a special square headed nut will be used. #0-80 square headed nuts and bolts will be used for the hose clamps. Some filling and metal finishing still needs to be done on the parts. The ribbed hose used here in the photos was a rejected experiment. The string used for the ribs was too large and not uniform in shape. The hose that will be used for the engine tender connections is much better. So that's it for the Okadee connectors. I hope you have enjoyed this thread. Now onto something else, I'm not sure what yet.
See You In The Funny Pages...
