There is a very long list of "other makes" on that website which Tony Griffiths does not cover in detail; Sieg (however spelled) does not seem to be on it.

I agree that there is a case for a representative minilathe to be included and I expect TG would be happy to do so if you write and illustrate the entry.

Nottingham Myford used to turn up at shows with Sevens in a variety of non-standard colours.

When I repainted my grey 1960s Super Seven I opted for the much more tasteful green - mutton dressed up as lamb!

Neil Wyatt:

There is an interesting reference to the Vikings' use of the sun compass and other navigational aids in this BBC item:

That was indeed the one I had in mind.

I have sent you a PM.

Neil Wyatt:

Thank you for exposing this old print to the light of day! Sun compasses and sun dials would seem to be an excellent school project.

It looks as though I should have clicked the Link icon rather than the Image one; I know I am not the only member who struggles with this software and would gladly exchange the Smiley icon for a Help button. It's awkward to have to go to the website FAQs in mid-edit.

I think somebody suggested a dummy (!) thread where we could experiment rather than inflict our mistakes on other members.

Michael Gilligan:

Thank you. A case of buffer overflow, perhaps?

What happened to the image whose URL I pasted in?

Brian Wood:

They say a picture is worth a thousand words!

Just PM me your address and say what size you want and I'll post - no charge, but consider "paying forward".

If you are cutting your own felts, I can supply the material (thick ex-papermaking felt).

Good find! I looked in vain in Salaman's Dictionary.

I think the pliers are a cobbler's tool.

Superb! Why don't manufacturers describe their products like that today?

I seem to recall that there were third party back gear conversions in the round bed's heyday. I suppose that Clive Foster's point about the capabilities of the drive belt may still apply, but back gear would be more in keeping than a VFD.

Nick Clarke 3:

Thanks for the photo; I see what you mean about the shank.

Mark Rand:

Thanks for the advice - I found it helpful to use a suitably small tap wrench.

I think you mean large end.

Thank you - that was exactly what I wanted to see. I was unaware of these until recently and am not sure why it was necessary to add to the old-style Jacobs tapers. Presumably, however, I can now finish a new style taper with the appropriate MT reamer.

John Purdy:

Many thanks.

My reamer has straight flutes and, as I suggested in another thread, I was concerned about the possibility of breaking it, particularly as the load on the flutes must increase as the cut progresses. In the event, I compromised by measuring the diameter of the pin at half way and drilling accordingly (the actual depth of my taper is only 15/16".

Lots of stuff on internet generally eg Yahoo 6x4 group.

The CAHW.exe MEW index would probably help, too. eg MEW 50, page 51
