|Thread: Digital speed control wiring|
Hi Kwil yes I've got the handbook which came with it
Hi. Can anyone help please, I have a LENZE SMD digital frequency inverter and want to know which wires go where for the full motor control, I have built a multi purpose tool post and want a variable speed control on my 3phase .37kw motor which will control the milling/grinding functions of the said tool post
What I actually need is a simple diagram showing which wires go from the inverter to give me variable speed forward and reverse using suitable pots as well as stop.
Any help with this request would very welcome

|Thread: Footplate height BR Class 20 deisel|
Many thanks Simon
Where can you get a general arrangement drawing? I've worked out most of the detail now but I would like more info on the bogie design, I've done a rough sketch to work from but any detail would again be helpful
I'm scratch building a 5 in gauge BR Class 20 deisel electric, I don't have any drawings other than an outline drawing showing general measurements such as wheel base, length etc, this model will not be an accurate dipiction of the original but i wanted something to get me going reasonably quickly, I need to know what the footplate height is from the top of the rail, also the overall height for a 5 in scale would be helpful,
|Thread: Just starting|
I'm just considering converting my milling machine to CNC but I'm finding it difficult to know where to start, I have a Viceroy Vertical miller its about 25 years old but had little use.
I'm trying to find suitable ball screws for the X & Y axis themn I need to find powerfull enough stepper motors
|Thread: Machining cast iron|
The reason why a deep first cut is take on cast iron is that quite often the surface skin on an iron casting can be quite hard as sometimes the casting may have become "chilled" and contain hard spots, a deep cut usually gets under these chilled area and cuts under them to remove the area.
As David says most modern cutting tools will cope, particulary the carbide tipped variety and a deep cut will not be needed, also modern foundry practices also reduce the prelavence of hard spots
|I used a couple of 25 litre plastic brewing buckets on for the citric solution the other for water to clean it off after pickling, I've seen these buckets in some garden centres also try a couple of plastic dustbins with the lids having a hold down clip on them, a lot of horse tack shops sell these as they use them for feed bins and they are not that expensive
