    IC engine 0,5cc or 0,8cc

    IU - possibly imperial units ? Other than that i got nuthin ! If that is the issue it isn’t difficult to convert to metric and round up or down to the nearest metric size . The engine I’m currently building is a bit of a basket case ! It has measurements in fractions, decimal,metric and uses...

    Trouble with cut off operations

I set the height and locked the toolholder down then tried a cut and had a dig in so i scratched my head a little and thought I would go over the set up again just to make sure I didn’t stuff something up .

    Trouble with cut off operations

    I can’t say i like the type of toolholder the OP is using as you can’t shorten the tool right up to the lathe toolholder and thus eliminating as much overhang as possible . I was using the blade and insert style holder but got sick of paying for inserts and blades - decent quality items are...

    Complete Model Engineering Shop

    I am truly gutted ! It saddens me enough to see old age claim a model engineer let alone to see one have a hobby they love stripped from them because of a physical ailment . I too have back issues but not in your league and standing for even half an hour can become excruciating which usually...
