Welcome! And while we’re talking suspensions,
Right now, Yahoo-owned websites such as Yahoo itself, tumbler, and relevant here, flickr photo storage, are loading exceedingly slowly, if at all, or I’d show how I gave my Bachmann bobbers 3 point suspension by changing one axle holder strap.
Steps;
1.) change mounting screws from 2 at ends to 1 in middle.
2.) remove the strap and cut wide enough slots in floor from just outboard of center screw mount to original end slots.
3.) shape floor each side of center screw mount to allow axle holder strap to dip down a bit.
4.) reattach axle holder strap with center screw and leave just loose enough for strap to rock side to side a wee bit.
It makes a difference in tracking.
Just tried Freight shed photos first time and uploaded relevant images.
Look for folder titled Forrest’s fotos
Also include marker lights made from Christmas light LED, styrene tube, and miniature electronics plug. Crude but effective.
Also used some blocks of foam to reduce “echo chamber” sound of empty caboose body.
