RSS Fetcher Posted June 15, 2018 Share Posted June 15, 2018 Well my experiments with servos are progressing along. The prototype was tested using a CCPM Servo Consistency Master tester on a 3.0 volt, 1.5 amp supply which enabled a PecoSE 195 code 75 turnout to be switched back and forth without the need to remove the springlatching. The 12 mm baseboard plus an extra 3.0 mm track bed underlay will be just fine for my purposes. Other than using surface mounted turnout motors , the under baseboard mounted approach does have its own alignment issues for making sure motors are correctly mounted. Problems seem to arise when a pilot hole is drilled for a track centreline from above to transfer underneath comes through at a odd angle that can add extra millimetres. To overcome this slotted holes are necessary to adjust your motor mount to the right position. This is far from ideal so I made a portable drill guide to to drill a perpendicular pilot hole from above to align the servos under the baseboard to the centreline of the turnout above. This ensures accurate alignment is achieved for all turnouts and motors, especially as I have a few to do. For my own drill guide I used a 160 mm x 60 mm x 30 mm hardwood block with four 10 mm holes drilled with a pedestal drill to ensure a perpendicular guide for my Proedge pin vice. This has an additional 12 mm long nylon collar fitted to it just above the vice’s drill securing collar. The pin vice can then be placed into a variable speed electric drill and a perpendicular hole can be achieved.Aside from enjoyable GWRM distractions my present course remains the same and that is to complete the first baseboard with its side panels for transporting and protect the buildings and diorama that also will be handy for the background scenery, then lay all the station approach South end tracks.
