There is no reason why a patternmaker should be able to cut a thread on a lathe. And a large thread on a modelmaker's lathe without change wheels is not possible anyway.
The Lidl's lathe now works perfectly. I have made another pen on it and a 'phone stand.
I don't like glass finishes on wood. I like to feel that it's wood. The grain is filled and it's waxed.
I have no idea how it happened, but I just once again tried the 3 and four jaw chucks from the metal lathe on the Lidl lathe and they did actually go on and tighten safely. I can't think what I was doing on Christmas day when I couldn't get them to fit, But today I used the 4 jaw on the Lidl lathe to make the 'phone holder. Worked a treat. The people arguing the toss on forums about the tool can go to Hell. Mine is fine and was a lovely Christmas present from my wife and I am enjoying the new hobby which is why she bought it for me. As to the rest, yes it is too wide for pens, so I have a friend making me a narrower one as he has welding gear. I don't know anyone else with a lathe, but now I don't need it. Since I have no reason to need the wide rest I may just cut the ends off anyway.
I don't think I can turn pens, I know I can. It's hardly rocket science, once one has the knack with the tools. I've just thought of doing it before.
I thought forums were supposed to be helpful. Your attitude stinks, so I shall not be troubling this slow and ponderous forum again.
