Confused, you don't have a die handle? How super duper do these threads have to be?Yes, but I would still need someone to cut the threads.

Actually, only the die would be required, and they do have one for about $8. As I mentioned earlier, I would prefer a somewhat harder bolt for this application (it is basically being used as an axle), and single-point threading is definitely preferred when threading a hard rod.US Stock HSS M10 x 1.5mm Tap & M10 x 1.5mm Die Metric Thread Left Hand | eBay

That is certainly a thought. I will look around. My lathe is a Chinese import from Vevor.Won't disagree with you on that. Maybe as an interim solution?
Maybe you could add a reverse tumbler to your lathe? I know there are write ups on doing this on a Grizzly G0602. I also have no LH threading on my lathe. Was thinking of adding the extra gear to mine.
Well, they need to be decent quality - there is a lot of stress on them. The main consideration, however is the size and hardness of the bolt. Cutting a new thread with a die is not a trivially easy operation. Cutting one in a 10mm somewhat hardened shaft is not the most comforting of ideas. If I try it, I will of course clamp the blank in my lathe and use a die follower.Confused, you don't have a die handle? How super duper do these threads have to be?
'Not an option. The rear axles are independent, and only penetrate into the rear support bar by about 20mm. The bar is over 35cm long. I am not about to try to bore a 10mm hole 35cm deep in what is probably hardened steel.Instead of threaded axles with nuts consider non threaded axles and snap rings.
Yes, I am quite interested. I will PM you later. Meanwhile, here are some photos. The wheels have 10mm ID roller bearings pressed into the wheel hubs. The existing bolts are 70mm long, one right hand and the other left hand thread. What I want to do is add a 2 inch 4142 steel cylinder to both sides, thus extending the wheel base by 4 inches. I believe this will be the simplest approach. Other than some minor machining on the two cylinders, all that is required is two 10mm x 120mm bolts. Obtaining the right hand thread bolt is easy as can be. The left hand thread bolt is turning out to be a bit of a challenge.Not really clear on the specifications, thread pitch, and how you want to retain the bolt. Mcmaster-Carr has 150-160mm range wither hex or cap screw. The threaded end can be removed and then thread the screw shaft on the lathe. It will not be a rolled thread which would be stronger. I can do that if you want and you give me the specifics. I probably would get two bolts and a left hand nut/or thread die, I can either cut 95% on the lathe and finish with a thread die or cut 100% on the lathe and just fit to a nut. Cost of materials plus shipping from McMasters and to you, if it is something you are interested in PM me with some more details of exactly what you want the bolt to be.
