    OK, I hadn't considered the type of relay you are using and you have the advantage of practical experience, so if the PWM duty cyles are being passed on by relay to the heater that's a problem solved.

    The values given in the decoder manual for CVs 137 (Standing) 138 (Cruising ) and 139 (Acceleration) are a bit on the low side. There's no need to be concerned about experimenting with these values. The maximum is 255 and this is equivalent to 'always on' (at track voltage, current depending upon the heater elements), and figure lower than this in any CV willproduce an 'attenuation' of the effect. try it ot, you can easily put the values back again if you do not like the results.

    The Seuthe type smoke units are little more than boiling tubes, but its possible to automatically (by the sound project) vary their output depending upon status using these CVs.

    Also, have a look at Cv355. This controls the fan speed at standstill. A combination of Cv365 and Cv137 should allow a constant but slow, less dense vapour when standing.

    The value in CV60 is used to dim all function outputs which are not specifically 'masked' from the effect. I don't know if use as fan sync, which is a special case, masks the fan fom any voltage dimming. I suppose the way to test would be to get this running then change Cv60 to a dramatically low figure, say 50.

    Good luck, I'm off for some food,

    Hi JB

    Thanks for the info. The only thing I can find in the manual refers to possible problems when using adapter board ADAPLU50. It suggests putting a 6.3V 220 uF capacitor across the +ve and ground. Does this ring a bell?


    Hi Paul

    Thanks, I’ll try a few things out and let you know what happens.

    Regards

    Steve

    Hi Paul

    I can confirm that F04 is not affected by CV60 when its set up as the virtual cam.

    Regards

    Dear readers who check the Recent Posts, the Love Lane group can't use Steve Baldock's fantastic locos anymore following his sad demise and would like to replicate the steam units in some of our own. Did anyone take up Steve's offer of drawings for the tank units or have knowledge of where he obtained the fans he was using in his later versions?

    Hi Robin, I was asking Steve about his steam units so I could put them in my loco''s. He told me what the heaters were but sadly died before he could build me the units, so I'm in the same position as you. I don't know if he told anybody at his steam company (Steam Traction World) what they were, but perhaps somebody might help with this question.

    Steve and I had a chat a while back comparing notes. I could be wrong but think he was using the units from Peter Clark with mods.

    I'm sure he posted details on here in one of his threads or something. Details of how he made the units up and machining required. Not had a chance to search yet though.

    Hi Cliff, have you got Peter Clarks email?

    Looking at the postings he had a 3D file on his computer, not sure if you can get hold of this.

    Thanks Cliff, Steve posted that info in this thread and had moved on from the Peter Clarke units to make his own out of PTFE. As Len says Steve created a 3D drawing that he offered to share but none of us asked for it until it was too late. As far as I know Steve used his own CNC mill to create the PTFE bodies. His business partner Dean may still have access to the files but I was trying to avoid asking him at the moment because he has been so busy dealing with the sale of the business and helping Steve's family sort out the estate.

    That's why I haven't email Dean to ask. Will have to wait and see what happens.

    Apologies for the blurred image. These were the fan blades that Steve was using last year. A cut-down plastic moulding, alas from a source I don't recall. -Brian McK.

    Hi Brian, do you know what heaters and motors he used and where from as he never was able to tell me?

    Len,

    Your post reminded me - M4 x 15mm - sorry about the delay!

    Please excuse the detour!

    Thanks Simon I got the screws from our local Spanish shop.

    Len,
    I think the heaters were from Germany, not necessarily Seuthe but whatever is used by some Gauge 1 locos.

    Have just uploaded a video clip of Steve describing the plastic base used for steam effects from draincocks and safety valves:
