Hi Guys,

Thanks for all the advice. Unfortunately I am not am electronics person and have no knowledge of testing a PCB, likewise no idea what a mosfet is or what it looks like. Spoke to Ian at Arc, who was quite interested in my problem and he reckons it is either the motor or board, favourite the board, and highly unlikely to be the speed controller. When I was checking the motor brushes one of the retainer grub screws shattered so I have to make a new one of those, looks like an M12 x 1 thread. I have a piece of 12mm delrin and am waiting for the die to arrive. Once I have made the new grub screw I will see how to attach the wires to the motor from the 12v battery. If the motor proves sound I will order a speed controller first, as it is the cheapest possibility, and if that fails I will order a new board. Hopefully I will be up and running after all that. I will also look for someone who fixes PCBs to have my original fixed to act as a spare. Incidentally I live in Oldham.

Cheers,

George

Thanks Steve will do.

Hi Guys,

Any advice on what might have failed on my Sieg X1L mill? Finished working last night and everything was fine, went to carry on this morning and although the power light came on the speed controller did nothing. Looking at the different component costs the speed controller is £10 and both the motor and control board in the region of £100. Is it likely to be the speed controller or is it a common problem and it is always some other assembly/component? The motor brushes look fine.

Thanks in anticipation,

George

Hi Bob,

Thanks for your offer I will definitely take you up on that. I have
not joined a club yet but I will when I start construction. I have a choice
of 3 near me Sale, Urmston and Rochdale. At the moment I am constructing
a gauge 1 4F to get some experience on an easier project as I am new to
this. I am looking forward to silver soldering next once the drier
and warmer weather arrives as I will be doing that in the garden.

Thanks again,

George

Hi DMB, I expect to have plenty of offcuts when I make the boiler, I have not silver soldered anything yet although my wife bought me the Sievert gear for Christmas. Making the boiler will be VERY interesting!!!!

Thanks for the advice Bob. Once I get started I will take you up on your offer of advice.

Thanks Lambton, JasonB & John for your answers. As John has written one of the biggest problems for beginners. I just could not see how to do it but at least I now know that it cannot be done perfectly but more of find the best solution you can based on the factors explained above and work from there.

Cheers,

George

Thanks Neil. The card Template sounds a good idea.

Hi Guys,

I am looking at building a 3 1/2 inch gauge Fowler 4F. I have bought the drawings from Reeves. One thing that confuses me is how to find the centre of the bores of the locomotive cylinder casting. Reading the articles that people have written it says plug the casting end with a piece of wood and mark out the centre. As the castings are rough how do I measure and mark out the correct position for each bore? Where do I measure from?

Cheers,

George
