Regner Lumberjack & Heidi

Regner LumberJack

Here Wolf Schlegel has fitted a Summerlands Chuffer to his Regner Lumberjack. His Photos and notes describe the process.


"The photo left shows the materials and items used:


    * first and foremost, Lumberjack itself

    * the instructions provided by Regner with the Lumberjack kit

    * the chuffer (leaning against the bottle with the blue liquid) and instructions provided by Summerlands

    * some tools

    * chemicals used for blackening the chuffer.


To make the chuffer less eye-catching, it can be chemically blackened using the blue solution provided by Regner. Before blackening the chuffer, it needs to be thoroughly cleaned as the oxide layer produced by the blackening agent is likely to wear off otherwise. Wolf has used benzine for this purpose, spirit and lighter fuel (or thinners - cb.) should do the job as well. The blackened Chuffer is shown top right.


When working with any kind of chemicals, always refer to the instructions for use and always wear eye and skin protection.

The Regner diagram (left)  illustrates how to remove the smokebox door. The photo right shows it removed.


It is always a good idea to keep small parts safe, e.g. by putting them into a tin lid. Wolf still managed to lose one of the screws when re-assemling the smoke box door.

Photo far left shows the exhaust pipe in its original state. In order to fit the chuffer, unscrew the swivel nut and pull the exhaust pipe through the chimney.


The photo shows (from top to bottom) the Summerlands Chuffer, a 6 mm spanner used for unfastening the swivel nut and the exhaust pipe with the Lumberjack's original chuffer.


The old chuffer is soldered to the exhaust pipe and needs to be cut off. In order to position the Summerlands chuffer at the correct height, the exhaust pipe is cut just below the old chuffer as indicated by the red circle.

Insert the exhaust pipe through the chimney and fasten it with the swivel nut. After this step, re-mount the smoke-box door.

Photo left shows the Summerlands Chuffer as viewed from above. Due to the chemical blackening, is it less noticeable than the other brass items.


As with Roundhouse Katie, the fitting process has been straightforward and took less than 30 minutes.


As with Katie and Riesa, the chuffer does what it says on the tin and provides a very nice audible experience."

Regner RhB 3/4 Heidi

And here Andreas Grund gives some note and photos on the fitting of the SCGP2 to his Regner "Thusis" loco:


"Please find attached some photos which explain about the Regner Thusis loco (photo right). Actually, the "Thusis" is a Swiss Rhaetian Railway G 3/4, which is sold by Regner as "Heidi No. 11" in a green version, "Thusis No. 8" in black and recently as "Bruenig" with a few modifications also in black. It is a nice, powerful loco with good performance, however, it runs almost "noiceless". Therefore I added the Summerlands General Purpose Chuffer SCGP2.


Fitting in the chuffer is easy, the original joint exhaust copper pipe has an outside diameter of 4.0mm (sorry, I live in the metric world...), so, the chuffer with 5/32", which is 3,96mm inner diameter can be easily sleeved onto the exhaust pipe in the smoke box. Of course, first the original Regner chuffer, which does not deserve such name needs to be removed - grip it with pliers through the chimney and pull it off with slight turns. The only real operation required is to cut the lower chuffer pipe by 8-10mm with a fine saw. As the photo shows, the Chuffer is mounted flush within the chimney, certainly it can be mounted a little deeper, either by cutting the chuffer a little more or by bending downwards the inner exhaust pipe. I also intend to paint the upper part of the chuffer with mat black to make it less visible.


The overall time demand is approx. 5min and the result is surprising: Full chuff! Especially under load. I run the boiler with a pressure of approx. 2bar. A small investment which really pays off!"
