Regarding Duncan’s earlier post where he mentioned the use of turbines operating on exhausts of reciprocators (the Bauer-Wach system) there is an example of this in the Model Engineer. Mr. Jan Hook described using his turbine with a ST D-10. e.g. the 6th and last part of his series is in M.E. issue of 3rd June 1988). This is a picture from his article – let me know if you want copies.

Hi Chris,

thanks for reminding me about the GTBA balancing info. I joined that association a couple of years ago to find out more about this and their other impressive achievements but I’ve not looked at the balancing stuff for some time. One off-putting aspect of this is that building a balancer will be another significant project. That is another reason why I hope to get a single stage turbine running initially since I hope that static balancing of that will give acceptable results.

Mike
