Doall 16 Lathe Manual
As some of you know, I have wanted to stop managing H-M for some time. It's a tremendous strain on my personal life. I want to set up my own shop. In September, September 15, to be exact, it will be 8 years that Hobby-Machinist has been in existence. I have been training VTCNC to run things here. Dabbler is going to learn too. I feel that they are ready to start taking over the operation.
I actually have two requests. A source where I might be able to find an operating manual for the DoALL 17 Lathe. DoAll 17 Manual. Doall 16 For Sale Used Lathes, Engine Vander Ziel Machinery Sales.
I will be here to help in case they need, but I don't think they will. Tony Wells is and will be here also to consult with. I will be doing backups, upgrades, and installing addons. Other than that, I will not be around. I am leaving this place in good operating condition, and financial condition.
--Nelson  • • •. This is going to be a long post and I have limited experience about this topic. I was contacted yesterday by a friend who works at a small machine shop that is closing down. He said they had several items for sale and one of them was a DoAll 15 lathe. Overall length is about 78', probably a 36 or 40' between centers. He said he didn't know a lot about it but he did know that it worked a year ago. The person who last ran the lathe has since retired and has no connection to the shop anymore.
I went in this morning to check it out. Now before I go any further I must say that I am retired and have limited experience running any manual lathes other than my own Smithy 1220.
I did run G&L CNC lathe at work, but for the most part I had very few hours on a manual lathes and that was 14 years ago. I also didn't have a way to take pictures that I can post. The machine was very dirty and it was evident that it hadn't been used lately. We were able to get the motor turned on and the spindle to run through different speeds but were unable to get the carriage to traverse under power. The lead screw (I think that's the proper term) didn't rotate and couldn't get it to no matter what levers we engaged.
I was able to get the carriage to engage on the screw and this of course made it so the carriage wouldn't travel manually. I think this tells me that the problem lies in the gear box and not the carriage.
For what it's worth I tried the feed rate levers in all the positions, there was also a lever with arrows pointing left and right, I tried them in both directions. I assumed these were for feed direction and I could also get the cross feed slide to engage but of course it would move because the feed screw wasn't turning. My question is where can I find some information on the DoAll 15? I find info on the DoAll 13, 16, and several others but nothing on the 15. For $500 and free delivery I would think I could get my money out of it for scrap if nothing else, but would surely like to get it running. It has with it several 3 jaw chucks a four jaw, a face plate centers, a QCTP and several tool holders plus quite a few turning tools.
Does anybody know by the limited info I have provided what is wrong. Perhaps a lever or combination of levers. Or does anybody know where I can find an operators manual. Like I said I have spent several hours online last evening and this morning after looking at it to no avail. I did tell him I would buy it. Thanks for any help.
I hope this is the correct place to ask these questions. I did come across that link after a while and some research.
On the page that you sent the link for, I do believe that by clicking on the 13', 15' late models,, the first picture that comes up is very similar to the one I am asking about. I also see that a manual for it is available too. Class 9 Science Vk Science Lab Manual. So I guess after this weekend I will go back and fire it up once more and again try all the positions of the lower gear change levers or what they call the 'screwcutting gearbox' and see if I am able to get the lead screw to rotate under power. Thanks everybody for your input and replies. I will try to follow up with some pictures next week. No disassembly, just open the gear cover on the left and look to see what drives what. The gear on the spindle drives another gear, which might have an idler that can be inserted to reverse the driven direction.
You should be able to do this even without powering up the lathe; in fact I would recommend not powering up the lathe until you know what the gears do. Eventually an input shaft for the quick change gear box (QCGB) is driven. The cover for that may also need to be lifted off or unscrewed but it may be well worth your time to see the gears in there, unless they're in an oil bath, in which case you might not see much. They are what drive the power feed or lead screw. If you do this you should be able to see where the disconnect is happening. Post pictures!
