Great job on this and all of your videos. I used to work at my Uncle's automotive machine shop in Long Island when I was in college. Before the advent of removable bearings he used to babbit and line bore engine crankshaft and camshaft bearings in Model A and later engines - those were the days! :)

The alloy and the set procedures allow you to weld and hot work it without stress relieving it! On the other hand the aquamet 17 has to be stress relieved after the process, but can still be done. Thanks for the comment and the question, reminding all of us that you just can't weld on any old piece of material and think it’s OK! ;{)---

Fantastic video, reminds me of babbitting thimbles on the end of 3/4' wire rope for a cable tool (percussion drilling) rig. Used muriatic acid for cleaning and stick for checking temp.
@KeithFenner
@KeithFenner 12 жыл бұрын
I would seem like it would! You still have to pour each half and then finish the split line shim and then set up to bore! In day there weren’t a lot of machine shops available to handle the machining needs and Babbitt was able to mold itself to the castings and be hand shaped for the running fit. There are still a few guys out there today that can pour and fit a bearing before a machinist could machine the same. ;{)---

@KeithFenner
@KeithFenner 10 жыл бұрын
It is an old marine shaft support bearing and the bearing has to be installed in two half's to replace or maintenance, it is a heavy load low speed so the old Babbitt bearing is better suited, and we wouldn't have to build a new ship around it to get a bronze bearing to work. ;{)-----
@KeithFenner
@KeithFenner 11 жыл бұрын
This and most pre heats are to raise the temperature, in the project so the arc and base materials are a little closer to the same temperature, lessening the shock of difference and relieves the pull or contraction between the puddle and base materials, following the weld beads applied. To help with flowing of metals, using lower amperage settings on your machines, while welding on larger projects, as you said is second reason, in this particular project. ;{)------

That's a huge diameter shaft, to me. How much torque is it handling? How big is the propeller? Or is the diameter more due to the length? I haven't (obviously) been around boats much.

Thanks for the comment! I believe that a machinist can learn to weld and a welder can learn to machine along with any trade for that matter, as long as the abilities to remain teachable and the workmanship expectations, on a individual bases, will govern the quality or level in that particular added trade or talent. ;{)---

Was the shaft diameter so critical that you couldn't just machine it smooth and pure a smaller Babbitt to match, or did it have to do with assembly of the shaft
