Prep work is going well and I am planning to have the basic frame and drive train subframe assembled this weekend, and will forward a photo then (if it works. If not, this conversation never occured!).<br /><br />Will we see any more of your WWI project? Since it is the other area of military history I am very much interested in, it was a kick to see your photos. I don't know if you have had a chance ot see any of the impacted areas, but the fighting was so intense and extensive that there is a lot of evidence existing in unexpected areas. In the woods on a farm I visited near Chateau Tierry /' Belleau Woods last year, you could easily see trench lines, machine gun nests and even individual US foxholes. Small arms brass still littered the ground under the leaf cover and I even tripped over a German gas mask. Sobering and evocative of the mood you captured.MattL331https://www.blogger.com/profile/16602267206238011710noreply@blogger.comtag:blogger.com,1999:blog-7108382665458119460.post-17012899469516930512013-11-07T11:00:17.999-05:002013-11-07T11:00:17.999-05:00Hi Bernard,

I get great satisfaction from seeing him finish a locomotive with one of my mechanisms under it, or a locomotive that I've had a hand in helping him tune and get the most out of. It's something I'm fully incapable of doing myself, and because of this, ours is a great collaboration.<br /><br />Regards,<br /><br />Jeff BissonnetteJeffBhttps://www.blogger.com/profile/03735160762294985972noreply@blogger.comtag:blogger.com,1999:blog-7108382665458119460.post-55258558435126177172013-11-01T21:48:48.148-04:002013-11-01T21:48:48.148-04:00Matt,

I can post them here if you like.<br /><br />I have both of the books you cite (thanks of Trevor for the Flexi-chassis booklet). I do find the Flexi-chassis book very hard to follow. I do find it interesting how the flexi-chassis book makes a big deal about adding slop to the chassis since everything is sprung or free floating. That just seems off to me, but having no practical experience in this matter I defer to them. Time to try some experiments and see what happens.<br />Berniehttps://www.blogger.com/profile/14041125155303909803noreply@blogger.comtag:blogger.com,1999:blog-7108382665458119460.post-54824513613424921262013-11-01T19:25:43.599-04:002013-11-01T19:25:43.599-04:00Bernie:

The bible of compensation/equalization is a little booklet by Mike Sharman called Flexchas. Also useful are the Gauge O Guild's on- line manual, and Iain Rice's book on etched chassis construction (both have a chapter on compensation). Finally, on-line there is the ScaleFour Digest Principles of Locomotive Suspension. I found the Rice book through International Hobbies in Auburn CA, I think, and the Sharman pamphlet through Abebooks. <br /><br />These are all British, and I have had little luck trying to translate their ideas into small, open framed 4-4-0s. The classic British equalized suspension for a 4-4-0 seems to have the rear, geared, axle fixed in place, and both the pilot truck and front axle free to move vertically, connected by a longitudinal beam on resting above them on their centerlines: that beam see saws on a cross bar about half way between them. All this is fine with a British slab sided frame to hide the works but is complicated to arrange and is in pretty plain sight on our style locos. Also, this arrangement seems to shorten the effective wheelbase of the already short wheelbase 4-4-0s of the 19th century.<br /><br />I have just started a 4-4-0 using Stevenson Preservation Lines castings and my planned work around is to mount the rear, geared driver rigidly, mount the pilot truck (equalized side frames like a freight truck) directly to a fixed height kingpin (given a short 16-17' distance between he rear axle and the kingpin, and some sideplay on the front driver axle, I am hoping to get away with simply pivoting the lead truck bolster on the kingpin, just like a freight truck) , and suspend the front driver axle on regular coil driver springs. I am part of the way through a subframe to hold the drivers, motor and gearing, so this is only theory at the moment, but so far it seems more promising than traditional British style compensation.
