• NONPROGRESSIVE ASSEMBLY OF RAIL JOINTS •
Final tightening
When the tool is used, it can be canted in the hole to
engage it with the GHS, and to follow it as it is threaded
into the wood insert in member ‘B’. At first engagement
the tool collar is usually best left outside the access hole.
Final tightening of the Gear Head Screw into the Wood.
Insert is accomplished by allowing the collar to enter the
hole, thereby maintaining firm engagement of the gears
as shown in
Fig. 2
.
Tightening can be facilitated thru the use of either a
common ‘spin-tight’ tool, or a ratchet wrench with a
1/4” socket.
Assembly Procedure
With the Gear Head Screw and Wood Insert in place in
members ‘A’ & ‘B’ respectively, the GHS can be retracted
as shown in
Figure 1
to allow the two members to be
slid into their final position nonprogressivly (within their
own lengths).
Initial ‘running in’ (threading), of the GHS into the Wood
insert can usually be done using only a finger to turn it,
without the use of the installation tool.
As shown here, nonprogressive assembly of
the joined members is done by retracting the
gear head screw
