It is all about fitting the point motors in the correct place, easily and accurately. Point motors that are fitted under the baseboard have to be fitted in line and square to the movement of the throw bar on the points (Turnout). Normally on your back, upside down and inder the layout makes for a difficult job getting the motor in the correct place. The Jig is designed to be lay on top of the track in line with the throw bar of the turnout. You can then drill small holes in the guide holes provided. In most cases these holes are the point motors fixing holes. Once the holes have been drilled you then go under the layout and offer up the point motor carefully threading the operating rod through the hole in the throw bar and lining the motor up with the fixing hole positions you have just drilled. Some jigs are a two part jig and these are described below. The drilled holes should be 1.5-2mm in diameter. This is just right for the fixing screws normally provided with the point motors. Once fitted its back up on top and a check that everything is in the correct place. Continue with the wiring of the point motor. The Jig can be used again for the next point motor. When it comes to adding scenic material such as ballast, this will cover any holes made previously.
Two Part Jigs
In some cases the standard jig would end up drilling holes directly in line with the track. In this case, a special oversize jig is used on the track and a second jig is fitted under the layout. The second jig has fixing holes to line up with the holes drilled from above and as you can see from this image the point motor sits in the frame and the fixing holes can be marked in the correct place and pilot holes drilled and the motor subsequently fitted in the correct place. The jig plate is removed once the underside of the baseboard has been marked. Howevr, as in the case of the one n the photo yiou can slide the plate off even if the motor has been fitted.
PL-10 not forgotton
The Peco PL-10 solenoid point motor has not been forgotton. For customers who have a mixture of point motors we have adaptor plates. There are two plates available and they convert from the SEEP and Twistlock type and the DCC Concepts iP and The Tortoise type motors. The conversion plate receives the motor in the same way as the PL-9 mounting plate but is larger in surface area. They have marked holes which line up with the corresponding type point motor. For example, you have twistlock motors and the older PL-10. You have purchased the jig for the twistlock motors. You use the jig in the normal way and use the conversion plate for the PL-10. Fix the plate using the holes marked T for Twistlock and the PL-10 will be in the correct place.
We also produce our 'Super-Easy' PL-10 mounting plates which are fitted in the old fashioned way without a jig but is slightly larger than the original and has longer slotted holes giving you more adjustment once fitted.
