Hello. I bought a Pinnacle hobby lathe but the half nuts were badly worn. It took me over a year to find replacement half nuts and in that timeI feel I have forgotton how to replace them. I have all the parts but it just looks like a jumble to me at the moment. I wonder just looking at your photo's if maybe you have any idea's.

Kind regards.

I had the exact same problem with a smaller blade. I logged on to you tube, typed in Bandsaw blade repair and found loads of positive links which were some help. Good luck with it. You don't need too much heat though.

Good Morning.

Thanks to everyone who had an imput in trying to help me repair my Hobby lathe this year.

I've made a bit of a start on putting the new half nuts back, but things have slowed a bit due to family circumstances and I hope to continue this Christmas holiday. So thanks to everyone who offered help.

To everyone on the Model Engineering website.

Wishing all thats good for Christmas, New Year, 2013 and beyond.

Hello.

Thanks to everybody who offered advice to help repair my hobby lathe I'm hoping to make a start this weekend Sun 18th and if not, over the coming weekends. I was eventually able to acquire the half nuts from Excel Machine Tools, Coventry. After a lot of searching around they eventually found some in a factory unit they own across the road. I'm just glad to have them...

Once again .

Thanks to everyone.

Joe.

PS I could be looking for a very cheap small used single phase surface grinder in the near future.

Hello. I have been able to acquire a pair of Half Nuts for my Hobby lathe. Thanks to everyone who offered advice and help. The ones I bought are aluminium and I look forward to trying to fit them over this coming weekend and if not, over the Christmas holidays.

If anyone has ever repaired / fixed half nuts on a similar lathe, I would apperciate any advice on how to re-assemble.

Many thanks

Thanks Russell.

I have actually thought of maybe altering / adjusting Emco half nuts to suit my Pinnacle lathe. I am considering useing Acetal but worry the half nut wall thickness is so thin it might not be strong enough to support the acetal inserts, so this is a real possibility.

Hello John.

Thank you for the info and link to grizzly. I Checked the site just now. The G400 lathe looks exactly the same, in fact, I have the original instruction manual / service parts list for the pinnacle and it's exactly the same as the G400 on the grizzly web site, even the same part numbers are listed with identical drawings of the various components. I'm thinking, could this be the actual replacement parts. I'll contact them within this coming week and ask for actual half nut sizes to compare.

Thanks again.

Hello Nigel.

I have been waiting for six months or more for information regarding the half nuts and I'm always fobbed off when I chase my order at Excel. The Emco does look strangly like the pinnacle. I checked the Half nuts drawing out on the web site and they are different, and maybe they could be altered / adjusted to fit my lathe eventually. Maybe thats the way to go if I cant get Acetal to work.

Thanks again.

Hello Nigel.

Thank you for trying to find the right parts for my Pinnacle hobby lathe. I have left a message with pro machine tools and I suspect I'll hear something tomorrow monday 5th. I did go on the Emco site and brought up various drawings of the half nuts, but there different to mine. There's have a slot cut down each side where lt looks like a retainer strip must locate, where the set I have are dovetailed.

Thank you for trying to help.

Thanks

Joe

Thank you so much Andy. ( I think I spelt your name wrong the first time)

I'm going to have a good look over the weekend at the sizes and hopefully buy some Acetal to get

this job started. Im looking forward to this interesting task. Maybe I'll contact you for some advice.

kind Regards.

Joe.

Thanks Ady.

Where would I get delrin from? and what is it? You advise making an aluminium set from the delrin,

How do I do that? Really interesting.. I'll consider anything, it's all new to me.

Thanks again.

Hello. I'm still looking for hobby lathe half nuts for my Pinnacle hobby lathe.I'm going to have one last go at finding a manufacturer / supplier before making them myself. Some people have been kind in offering advice on how to repair them useing various compounds but the nut wall thickness is so small I feel it might not be strong enough to support the new inserts. Is it possible to find a good supplier at a reasonable price.

Any help would be appreciated.

Joe

Thanks Russell.

Food for thought.

Hello Les.

I've just sent you a posting thanking you for your advice. I don't know if I pressed the wrong button or what happened. So I'll thank you again.

I've looked at the web sites which have given me some ideas and need to learn more about the processes.

Once again.

Thanks Les.

Hello.

I have bought a pinnacle 918 hobby lathe, very accurate, but the half nuts have been worn so badly that theres no thread in them at all. I have ordered some new one from the supplier, but they can't tell me about delivery or anything, I was looking at the old worn ones which are made from aluminium and it accured to me maybe I could get these nuts made from cast iron or with a little help maybe make them myself.

Year of manufacture 1978

Anyone help!
