Adjustable Module Legs

One of the most aggravating aspects of setting up a modular model railroad at train shows is the need to adjust the module legs. This is necessary to ensure that the tops of the modules line up and are reasonably level, compensating for any unevenness of the floor. I have experienced this at venues with very smooth and level floors (such as a curling rink) as well as at venues that have very uneven flooring.

This process usually entails a lot of crawling around on the floor with a wrench or screwdriver or, if you are lucky, bending over with a screwdriver if the leg adjustments can be accessed from above. Needless to say, this is quite hard on the knees and back. The more uneven is the floor, the harder it is on one's body and the longer it takes.

I have had the pleasure of participating in a few events at which members of the Spokane, WA Free-mo group were present. I noticed that they had devised a couple of different systems by which their module legs could be adjusted from a standing position. Once of these systems involved the use of nested PVC pipes which have an internal threading mechanism. To adjust, one simply reaches just below the top of the module which is at hip-height and turning the top portion of the PVC pipe to raise or lower the leg. The other system consists of a threaded rod which has at its top end a nut. Using a cordless drill equipped with a socket wrench one can raise or lower the leg with ease.

As I see it, the advantages and disadvantages of these systems are as follows:

Adjustable PVC Pipe Legs
Advantages
  • Easy to adjust
  • Easy to explain to others how to use
Disadvantages
  • The legs are quite heavy
  • The existing legs that our Free-mo group uses would need to be scrapped
  • The PVC pipes are fairly expensive
  • One of the older gentlemen from Spokane pointed out that his grip is not what it was when he was younger, making it difficult for him to turn the PVC pipe

Threaded Rod System
Advantages
  • Easy to adjust
  • Easy to explain to others how to use
  • Can easily be added to existing wooden legs
  • Are reasonably cheap (about C$ 6.75 per leg)
  • Easy to build
  • Not difficult to adjust if one’s grip strength is weak
Disadvantages
  •  None that I can think of


Having concluded that the threaded rod system is the way to go, I retrofitted the legs on my Aspen Free-mo module with the new system. At the next train show where our Free-mo group participated I demonstrated the simplicity and benefits of my module legs. Everyone in our group agreed that it would be a good idea to install these on all our modules. I undertook to install them on everyone’s modules except for one where the owner elected to install these himself. The reason I volunteered to do the work was that it seemed to me that any benefits from the adjustable legs is not in having them installed on only one or two modules but having them installed on every module. Human nature being what it is, leaving this to each member to do himself might have resulted in some procrastinating while others got on with getting it done.

There is an idiom sometimes attributed to Cervantes in The History of Don Quixote, “The proof of the pudding is in the eating.” At the train show following the installation of the adjustable legs on all modules our group estimated we saved at least 45 minutes of setup time but, better yet, our knees and backs were thanking us.


I greatly appreciate the creativity of Alan Cunningham and Jerry Barsness of the Spokane, WA Free-mo group and for taking the time to explain their great ideas.
