Guys--I need a little help here--I've long been a fan of of the amazing mechanical capabilities of guys that worked in the woods and how they could 'cob-up', rebuild wrecks and make do with almost anything.
The Rennie & Goose Pond ry will have a 45mm 'Shay' pulling a four car consist with rails and an RC Barnhardt loader to pile things up. My Shay will be built out of what they had or could scrounge. I envision a 2 and 1/2 truck vertical boiler similar to Laurie Green's great model. Two and half because that was all that was useable from the pile at the bottom of the ravine.

However, I will have a back 'porch' where the tender would have been on the 3 truck Shays and this is where the loader will live during the trip down the hill to the pond. I have a sketch and tried to get some pics, but not working yet. Too fuzzy. Will post when I figure it out.
Here's where you come in. I don't want big gormy Bachmann power trucks as it will spoil the delicateness of what I want to do. I can't seem to find any bevel gears to drive the axels. The main motor will be in the boiler and drive a hidden center gear on one of the axels and the rest will be driven like the prototype.
Any thoughts or where I can find the right stuff. I'm assuming that I want brass, but certainly don't want plastic. Maybe some junk Spectrum truck frames might be a place to start.
Thanks fellas--Duncan

Duncan-you might look for bevel gears (differentials, etc) that work in r/c cars. Most of these are made of metal and would probably be within the size you need. Larger r/c helicopters have bevel gears in the tail rotor drive setup, possibly OK. You could also check what's available at EDMUND SCIENTIFIC, they might have these gears. They are out there, you also might send a PM to Herb, he knows all and tells all.

Woodie and Herb--Thanks so much for your help and encouragement.
I just FOUND my Rennie & Goose Pond Ry. It's the John Lindsey Lumber Co. running on 3 foot rails. PERFECT!

Click on the Lima 290 and there she is. This puppy is a pole lokie with lugged saddle wheels and wooden roster poles front and back. And for a minute I thought that one of the new 'crop' from the Gila was there too. Oops, sorry Mrs Lindsey, but take that as a compliment 'cause them new ladies is really sumpin.
I won't do the pole road (I think)--talk me into it.
I may have to put off sailing this summer and get right on this.

Try not to give up on the sailing bit, just try to squeeze them into your free hours.
This summer will not come around again.
I spent near on 30 years sailing from J24's thru to Ocean Racing. Those years still give me great memories.
Get stuck into the modeling, come on you can do both.

Don--Thanks for the sailing thoughts. I was sitting at my desk trying to calculate my J so I can cut down the roller furling as I shift to a fractional rig this year when I figured I'd take a break and open Free Rails and dream a little more about how I'm actually going to build a single axel Shay truck so that it won't torque itself right under the frame. The answer is a modified goose neck at the pivot point.
J 24's are tons of fun, but as I got older I discovered that the young 'uns were taking it more seriously than I was, so.........
