Tweaking The Lionel Mogul

As always, nice work Pete!

Nice job!

what did you use for the whistle cord?

File this under, there is more than one way to skin a chuff rate. Made easier because this engine has a retaining plate for all of the driver bearings. Drop the plate, remove the crank pins, remove the driver set.

The two lobe cam bearing for the chuff switch was replaced with a 4 lobe cam. Bob's your uncle with 4 chuffs and 4 puffs. no other mods needed. Cost zero dollars using scrap aluminum but about 4 hours time.

amazing work as always

I love the details, where did you get them?  Also, do you happen to have any drawings for the 4 chuff cam, as well as detailed instructions on how to replace the chuff cam?

No drawing for the cam. I just measured the large and small diameters of the 2 lobe cam and milled the depressions to match the small diameter, then cut the corners to match the large diameter. I started out with a piece of 1/2" square stock aluminum in my mill vice and milled the depressions with a ball end mill. Then used a four jaw chuck and live center in my lathe to round the corners. The axle diameter is 4 MM. A #22 drill (.157") is a sliding fit on the axle but tight fit on the knurling.

As for details the cab deck material and air hoses are Precision Scale brass. Nut, Bolt, washer castings are Kemtron from my HO days. Eyelets are Lionel and Precision scale. Other pieces are just fabricated from wire and sheet brass.

The cab curtains are resin castings made from a mold of MTH curtains. Slowly I have been adding these details to all my older engines.

I modified my flywheel puller to pull the wheels and cam after scribing a witness mark on the axle so I could replace it in the same position.  I can post pics of that tonight.
