THE SUMMERLANDS CHUFFER

Richard Page has come up with a simple method, but it is not for those of a nervous disposition and I cannot recommend it as I have not tried it. Here is what Richard wrote:

"I recently purchased 2 chuffers for a Cheddar Goliath and a Cheddar Reisa. According to your website there was a need to virtually dismantle the Reisa and quite a complicated amount of work for the Goliath.
 
I have just successfully installed chuffers on both with a total time of less than half an hour's work for the two. All that was needed was to gently tap off the front of the smoke box. This can be done with a wooden drift on the false hinge on the left hand side. Slide the Chuffer down the funnel, mark the exhaust pipe 20mm above the bottom of the chuffer when the top of the chuffer is just below the top of the funnel, and cut. I used a Dremel which means the cut cannot be at 90 degrees but it takes virtually no time and the exhaust pipe can be supported by holding it with some pliers.
 
Then slip the Chuffer over the exhaust; ensure the steam outlet on the Chuffer is well away from the side of the funnel by turning it to the best position. The longest operation was putting a slight bend in the exhaust to get the right tightness of fit. Push the smoke box front back on and the job is done.
 
Wonderfully simple and a wonderful improvement to the sound of the locos."

Please note that Richard has given this account on the basis that it is one option. It could damage your loco and if you are in any doubt - please do not attempt it.

Cheddar Goliath

Brian Staines has provided the following fitting notes for fitting the SCGP3 General purpose 3/16" Chuffer to his Cheddar Goliath:

The base of the smokebox is fixed to a base plate (two screws) which is in turn fixed to the side frames (four screws).
It is helpful to remove the buffer beam from the front of the side frames (four screws) and the front of the smoke box base plate (two screws). It may be possible to remove the base plate without removal of the buffer beam but it gives more clearance when removing and replacing the smoke box and base plate.

Removal of the smokebox .
1) Remove the four screws fixing the base plate to the side frames and the two screws fixing the base plate to the buffer beam.
2) Remove the four screws fixing the buffer beam to the front of the side frames.
3) Remove buffer beam.
3) Slide and lift the plate with smoke box attached forward to slide off the boiler and clear the exhaust pipe.
4) Cut exhaust pipe 73mm above the base plate fixing lugs on the side frames. (please note that the SCGP3 Chuffer now has a longer 35mm fitting pipe so this measurement may be different CB). This will give the required dimension of 5mm from the top of the chuffer below the chimney top rim.
5) Slide chuffer on to exhaust pipe. If a loose fit squease lightly with pliers. (or put a very slight
bend in the exhaust CB).
Replace Smoke box.
6) Slide smoke box over the chuffer and exhaust pipe and push onto boiler.
7) Replace buffer beam and fixing screws.
