Paul you had my head hurting trying to keep up for a bit. Haha. Great job on this. I've got a 1944 SB13 and my threading operations result in slightly lopsided threads, which means my half nut has some wear and should probably be refurbished at some point. I rebuilt my lathe last year and it didn't look too bad, but I think it will have to make the project list this year. At least now, I have an example to follow. Cheers, Gilles
Hi, it looks like a lot of work, but apart from the bed ways and the straight edges it isn’t too much work for a lathe that cost next to nothing.. cheers
Been looking forward to seeing your process fixing the half-nuts, and even then I'm 2 days late to the show! Good show and good idea making liners! It's always great to see another person's process and yours is very creative and cunning!
Hi Hans, Ive had a life time of problem solving mainly because the drawing office kept breaking pencils until they got computers, then they went metric and cocked everything up. cheers
i really like the way how you fixing things mr hopewell, you are a true metal professor ! i was wondering, why aluminium and not brass ? thanks for the vid, cheers ben.
Hi, I once used to fly microlight aircraft and one part had to be replaced every year… this part was commonly called the 'Jesus bolt’ believe me if it malfunctioned thats all you have got time to say before your demise.. The thing is the bolt was made of certified hi-quality steel. This bolt passed through an aluminium bracket that never seemed to wear. One of my aircraft had several bolts replaced but the aluminium bracket was still faultless and showed no sign of weakness or excessive wear. The aluminium I used is very good quality material almost aircraft grade in the way that it cut. So I’m expecting great things from this repair…. on the other hand.. regards
@@Thesheddweller Hi, love your channel. Have you considered that your jesus bolts could have been wearing out before the aluminium bush due to it acting like a lap? The softer metal getting grit or harder particles embedded in it and then wearing away the steel bolt.
@@Bob-gc4rc Hi, thats exactly what was happening, and it was easier to replace a bolt than the entire suspension bracketry. It’ll be interesting to see what happends on the lathe after a bit of use. Cheers.

Back in the 60’ and 70’s we had a Luscombe tail dragger airplane. If I remember correctly the wings were held on with an aluminium pin. It was not a wear point.
@@glennwright9747 Which sort of reinforces my reasoning of using a good quality aluminium. I didn’t use any thing else because I hadn’t any thing and I have to watch the pennies at the moment. cheers
@@Thesheddweller I understand watching the pennies. With the cost of fuel these days I am suddenly aware it costs about $1 per km to drive my truck! And that does not fully include maintenance and insurance. Makes you think twice nipping out to pick up a small item. The drive can cost more than the item. Buying a Tesla is not the answer either. I will be long dead before I ever save enough fuel to pay for the luxury. Fixed income retirement makes me feel miserly even if by many standards I want for nothing.
Wow Paul, that's a really good solution, well thought out and brilliantly executed. Very well done Sir! I think the aluminium will work ok - leadscrews don't move very fast and I wonder if another benefit of those additional holes from a previous project, might actually help with lubrication? I wonder if you could set up an oil dripper (as found on the Myford ML7) to make sure that the aluminium gets proper and permanent oiling. Excellent work... take a pay rise and an extra two weeks holiday... tell the boss that I said it was ok! Greetings from Southport.
Hello Paul,
Don't you love it when a cunning plan come together... nicely done. Enjoyable viewing, thank you.
Take care.
Paul,,
Hi Paul, yeah Its great, I’ve just got to get the next bit done now. cheers
What a genius solution!
Hi, thank you.
Your 4-jaw chuck assembly is brilliant, love it.
Hi, i made a video of it, if you’ve not seen it. cheers
What a complex little project. Enjoyed the content thx
Hi, thanks, glad you enjoyed.
When all said and done very clever approach to the problem of process. Well done as usual.

Hi, thank you, Cheers.
Nicely done😃 👍🏴
Hi, thank you. cheers
What a lot of work you are having to do! I hope my old Hardinge never needs this level of work.

that's a really clever well thought out fix and it works!
Hi, sorry i didn't reply, I missed your comment. Many thanks,. Cheers
BRILLIANT!!!! What a joy!!!
Excellent Thanks for the video
Hi, thank you , you’re welcome. cheers.
Great job Paul! I would think the extra holes would actually benefit in the lubrication aspect.
Hi, i’m counting on it, cheers
Could not of done it any better my self! Nice job sir! Thanks for sharing, Ken
Hi, thanks you’re welcome cheers
Very nicely done.

Absolutely brilliant. Your problem solving is marvelous.

Wow Paul, Fantastic repair...you put in a lot of thought and planning. Great solution and results !!
ATB....Dean
Hi Dean, thank you, not much more left to do now. cheers.
A well thought out and brilliantly executed repair, why weren't all halfnuts made that way?
Phil
Hi, its all down to cost I’m afraid. cheers.
Quality work as always Paul 👌
Hi, thanks
Job well done.👍
Hi. Thanks
Very nice work. My half nuts is also worn. However I’m going to fit new ones. I’m not on your level of skill yet.
Nice job Pau
Hi Tony, thank you. not much more to do on this lathe. cheers.
i really like the way how you fixing things mr hopewell, you are a true metal professor !

@@ThesheddwellerYou might want to keep a close eye on your lead screw for wear.
@@Bob-gc4rc Hi, thats exactly what was happening, and it was easier to replace a bolt than the entire suspension bracketry. It’ll be interesting to see what happends on the lathe after a bit of use. Cheers.
Fascinating approach. I'll be interested to see if the durability of the aluminum is satisfactory in your application.

Здравствуйте. Скажите диаметр винта и шаг резьбы. Диаметр 16 шаг 2 миллиметра? Или 1.5 миллиметра
Привет. Это не метрическая нить, это имперская нить. Если память служит мне правильно, это квадратный винт с 6TPI над 7/8». Надеюсь, это поможет. Ура.
@@Thesheddweller дюймовая. Дюйм=25миллиметров (25:8) ×7=21.875миллиметра. 6TPi=4mm.12TPi=2mm..17TPI=1.5mm из таблицы шага зубьев?
Was the Baldric reference intentional?
Oh yes. you’re the first to comment on that. cheers
@@Thesheddweller You nailed it.
