Earthdog Liner Designs

Over time the design of Earthdog tunnel liners have evolved. We no longer use 10 foot sections with fixed turns. They were too heavy for normal people to lift and the wrong piece was always in the wrong place. There are many different ways to construct proper tunnel liners. These are the two examples of the liners that are used most often in So California. The following pictures and files show the Great Western Terrier and Dachshund Club Of Santa Ana Valley liners. They are generally the same except for the placement of the roller and constriction elements.

GWTA EARTHDOG LINERS
This first set of pictures are part of the tunnel liners used by the Great Western Terrier Assn, they are available for all member clubs. These are limited to 15 feet of liner and do not include any of the ME extras. GWTA has enough liners for separate IQ/JE/SE-ME tunnels at the same time. Most liner sections are 4 feet long with connectors making up the extra one foot. There are usually two long runs of ten feet, two sections, with the entry tunnel and judge end making up the remainder of the thirty feet. There are other pieces that are no show. Those are the special sections that allow the roller and constriction pieces to be inserted into the middle of those sections. Also not shown are the "extra room" section with a door on the top to inspect and place bedding and the "extra exit" section. The "extra exit" is clearly marked to prevent it being contaminated with rat tea. With the corner lids and "joiner lids" between four foot sections, all areas of the tunnel are readily accessible to scent or retrieve recalcitrant terriers. (See Duffy's Tail on page one.) There are extra holes for the dowel fingers in the judge end, these are primarily for practice or some retrievals. The dowel fingers have unfairly been christened Duffy Bars.

This is not all of the pieces, more pictures later.

NOTE:
1) With the new rule changes, the SE-ME judge end has the doors altered so that one section can be locked down to conform to the different SE and ME requirements.
2) An access door has been added to the top of the entry section of the SE-ME liners to make it easier to place the rats 12 inches back from the tunnel mouth.
4) The "spare room" and "unscented exit" sections have grooves at the end to allow for slider pieces to be used to block off those sections of the tunnel as needed.
5) All of the tunnel mouth sections for IQ, JE and SE-ME have one end that has the top flush with the end of the tunnel mouth. The SE-ME tunnel mouth has dowel holes for the placement of the dowel fingers for use in ME walk up.

DCSAV EARTHDOG LINERS
The general construction of the DCSAV and GWTA liners is very similar with two main exceptions. The DCSAV liners have the ME roller and constriction pieces inserted between liner sections, not requiring special liner sections for that purpose. In addition, the quarry box and "judge end" are a small self contained unit that can be added to any of the generic liner sections. DCSAV has fewer specialized liner sections.

This is not a full set of tunnel diagrams, they will be completed at a later time.
