Kearsarge Windlass Engines

That was a pretty clever way to round the top of the bearing blocks!

Perfect bearing lids!
Anyone who has milled as much brass as you knows all the tricks.
Some material is now missing due to the cut with the saw. Do you put thin brass strips in there. Otherwise you won't be able to screw the lids on properly.
In old drawings there is also a gap between the bearing shells and I think there are brass strips in between. I think I've seen this before on full size engines.

I don't  bother with the shims, just take the screws in enough to hold but not tightened down. On full size the shim strips are normally used.

If anyone ever asks where the shims are, just say they're made of transparent aluminum, like the shims on Star Trek!

Got some fish in the fridge, will that count as the whales in the cargo hold?? 


Anyone young here will be wondering what  these two old farts are talking about!

That was a good episode! .... so 3 olde pharts!

Made up a couple sets of studs for holding the engine bed down as well as the bearing caps

and have started prepping the stock for the crankshaft. This one has counterbalanced webs that are 2" OD and 0.264" thick - worked out easiest to cut them from a piece of 2" 303 stainless round bar. I've rough cut the four discs on the bandsaw and started truing up one face of each, then will trim them to thickness. Also have started turning down the flanges for the end of the crankshaft where it joins the worm gear shaft.

Got the flanges to join the crankshaft and worm gear shaft mostly finished, just need to drill for the pins to hold them to the shafts.

Also have the crank web blanks trimmed to final thickness, and drilled the center holes on the lathe. For the crank pin holes, they were held in the three jaw on the mill with a pin to align the center holes while drilling/reaming the outer crank pin holes. These holes are smaller than the OD of the crank pins, which will get a step on each end so the webs will sit against the shoulders to ensure proper distance apart...

Please could you put that into words, once in a while?

Interesting that you don't shim the bearings, just use the holding down bolts
