Lathe headstock bearing access

[Mike HurleyParticipant @mikehurley60381]

I need access to a bearing in the headstock of my old BV-20 lathe. The ends of all he gear trains are covered by a ‘plug’ which I need to remove. Each has a small (5mm) tapped hole in the centre.

I assumed this thread woud allow me to either a) fit a screw and use it to ‘jack’ the plug off or (b fit a lashed-up extractor to pull it off. Neither method has been successful. The threadsize is so small I don’t dare put to much force on it as it’s so light it may just shear off (have tried until I literally couldn’t turn the allen key any more.)

So, anybody seen / done this before? It seems overkill to start drilling holes / applying excessive force at this stage. Any suggestions appreciated

That style of plug was usually removed with a slide hammer when I used to work with such things. All the fitters had some form of slide hammer in their toolboxes – usually “home made”  and with interchangeable threaded ends to suit different applications.

Many thanks Nigel, hadn’t thought of that one. I’ll lash something up when I have chance and give it a go.
