I have seen a lot of pixes showing wood beams on archbar trucks, generally logging cars--but others, too. If you Google 'archbar truck' I think you'll find several, some have steel, others wood bolsters.
Les - In addition to sprung vertical travel, swing motion trucks had a degree of lateral travel as well. The SPCRR organization is rebuilding some Carter Bros. swing motion trucks, and is also building two new ones as part of a boxcar restoration.

Okay thanks for the info. I also have an unassembled pair of arch bar type trucks made by North East Narrow Guage, Wiscasset Maine.
The springs are part of the casting. Do these have much value? My plan is to cut out the fake springs and fashion something better.
Thanks for taking time to post. C., that builder's log you linked is very welcome. I tried to post some of my own pixes and blew something out of the water, I'll try again. On some pixes of archbars, there is a pronounced 'arch' in the top horizontal sideframe bar, like this:
While on others, there's this look:
Got that second pic in. (Not real good at this).
A mug shot of me, happy:
Thanks to both of you.
Added after posting: Dwight, that link on the lateral play couplers showed me something I'd never even thought of, the lateral play. Thanks. Posting these pixes makes me a tad shaky.

You're welcome Les. " src="http://www.mylargescale.com/DesktopModules/NTForums/themes/mls/emoticons/smile.gif" align="absMiddle" border="0" /> As a dweeb machinist myself, I in turn appreciate your contributions to the machining topics.
Just making payments on all the patient, kind help I've gotten. I wonder if folks recognize how unusually friendly this board is?
