An early start saw me anxiously placing the template that accompanies the motor beneath the point.
What perturbed me somewhat was that in most of the (helpful) online videos about fitting this new type of motor, none was specific about the orientation of the switch blades when lining up the hole in the tie bar with the pin ‘target’ on the template (which was made a little more difficult by my age-ing eyesight
).Past experience has shown that the blades need to be centred to avoid a bias which usually results in the pin ‘catching’ on one side of the hole, but in all the videos I watched, it appeared that alignment was simply achieved by switching the blades either to straight ahead or diverging road: whichever lined up with the target on the template below
In practise, it transpired that (allowing for inevitable plus or minus tolerance in all my failing accuracy
) alignment of tie bar hole and ‘dead centre’ target was achieved when the blades were indeed centred. Peco have probably allowed for leeway with their specification of a 6mm hole, but I didn’t want to stray too much to reduce disappointment later.
Thankfully, the hole cannot be seen when the point is replaced.
Template fitted and the three holes drilled through with a 1.5mm bit. The centre acts as a pilot for the 6mm bit:
Baseboard turned over and the below board holes displayed:
The plastic lugs, to which the ears on the point motor body attach, in place:
The motor attached to lugs and here I met my first minor issue (the below board pin is a tad too long for the standard 2”x1” frame I’m using):
The snips weren’t up to the job with the motor in situ, so it was removed, placed in the vice and back out with the piercing saw (this is the joy of this new motor: it’s so easily removed and replaced ):
Template revealed excellent accuracy when board turned back over (and I can’t even knock a nail in straight
):
And finally, the point replaced to its starting point with pin easily slipped into tie bar hole:
First (manual) testing results are good: free movement of blades in each direction. Now it’s a case of marking pin, and back into the vice for cutting to length with the piercing saw again.
Apologies if this was a bit boring, but hopefully it might be of some small assistance to those thinking of purchasing this new type of motor, and who like me, have a skill set second only to the very basic tools available to them.
No connections to Peco (usual disclaimer).
Only another four to go…..
