Dear Helpline,

Since I adopted the Stubby method of Bowling I have been thrown out of a dozen Alleys. What am I doing wrong?

It was probably your overarm technique they may have deemed it throwing.

Track glue has dried, and the points are nicely immobile.

Next I can either add more cork and track, or upturn the board and install the 1st point motor and gubbins.

Do the blades move?

A bit of detail about the point gubbins.

 

First some bits: plastic triangle corner strengthener, some lengths of dowel, paper clips and small headed nails.

The plastic covers have two holes enlargened, so the dowel slides through easily.

A paper clip is straightened, pushed through a drilled hole and the end wrapped around the dowel. The dowel is passed through one of the corners and a small nail tapped in a right angles to the paper clip.

The first pair of point actuators are in place, but not fully connected.

Observations so far:

  • The paper clip might be too weak and possibly be replaced by a stiffer wire.
  • The mounting of the Cobalt is in the best place to give the longest throw, whilst still allowing the choc blocks to be reasonably  close.

That's clever mate.

I used something a bit like that for the same motor that couldn't sit under the point . MIne was not as crafty though; just a straight bit of PCB (is that the thing for soldering to track for sleepers?) doing a  simple push pull job on the Peco point sticky out bit, drilled and pinned to the PCB.

The Point rod just went through a hole on the other end of the PCB (about 3 inches long and it sits in a groove, retained by Staples, in the Cork on my board (s). Just covered it in masking Tape for when scenics scattered on top. Seems to work OK  and I dun it myself:blink:

Well, that didn't work.

 

Despite the minimum movement required to change the point, there was far too much mechanical loss in the mechanism between the tie bar and the motor.

The paper clip was replaced with a stiff nail, the motor was repositioned, but all to no avail.

So, I did this.

However, this does not mean the idea is dead, it just needs refining to remove the issues.

In order to operate some turnouts on one layout I fitted a length of plastruct tubing on the baseboard surface from the hiding place of a tortoise to the stretcher bar/sleeper. And then put bras rod through the tube to operate the tiebar. If there is nothing to restrain the rod/wire it either needs to be very thick to avoid flexing and hence loss of movement.

If you are using wire in tube the tube needs to be fixed to a surface.
