Re: Machining 1018 Solid Steel Bar
Ron, thank you for the attachment, for SB How to run a lathe, as this keeps me from trying to find my copy. I know where my machinist handbook is though. I will review these items that everyone has

Re: Machining 1018 Solid Steel Bar
I took a class in machining, but I learned how to dial in a 4-jaw chuck from Little Machine Shop. I put a 5" 4-jaw my my 7x10 mini-lathe shortly after I got it. A bit too heavy, but very useful.?

Re: Bending mild steel strip
Some caution about drilling holes before bending.? Due to how the metal stretches at bends, it can be a bit tricky to place the holes on a flat pattern, so they end up right after the bending.? Most

Can also use a fire pit or BBQ grill, and a shop vac to increase airflow. Though a propane or butane torch with a good pair of pliers and a 2lb/1 KG ball peen or cross-peen hammer and an "anvil-shaped

Re: Bending mild steel strip
If you need them bent in the same location, but opposite directions, use a jig - even if it's just made from scraps.? A little forward planning and careful drilling would let you bolt/screw the jig

Re: Bending mild steel strip
If you are in USA, Harbor Freight sells some inexpensive tools to bend iron and steel. Check them out and maybe one of them will help you. Best Regards, Andrei mailto:calciu1@...

Re: Bending mild steel strip
Hi Peter: Assumption, all the same size? And you have a vise? Are the bends in the same direction? Or opposite? Even a propane torch can help. On the 30 deg bend, a larger radius would help. Cut a

Re: Machining 1018 Solid Steel Bar
Tamra; Some months ago I mounted a 1.5¡±galvanized pipe cap in my SL1000 to turn it down into cylindrical shape from its curved shape. Using standard Unit Bits, I was able to accomplish the task with

Apologies as this isn¡¯t Unimat (or even lathe) related - I¡¯d appreciate some advice from those who will know. I have to make three identical ¡®legs¡¯ to support a metal shallow bowl water

Hi, two comments. Finish. Since you can grind HHS, just grind one to the specifications in the classic Southbend How To Run a Lathe (

Re: UNIMAT 3 Watchmaker precision package
Hi Tamra, It's always good to read, and manuals often need to be reread (many times) ... As to why I think the Ebay item was not identical to the EMCO watchmaker precision package's tiny toolrest:

Re: Machining 1018 Solid Steel Bar
A 3-jaaw or 4-jaw will make no difference in accuracy for this part.? It is having its diameter turned down.? It is not necessary to have the stock size diameter running completely true. A 4-jaw is

Re: Machining 1018 Solid Steel Bar
Tamra, if you have a 4-jaw independent jaw chuck, that would be better for accuracy. Takes a bit longer to dial it in, but if you're patient you can get the very best accuracy your lathe is capable

Re: Machining 1018 Solid Steel Bar
I would get your bigger machine for a job such as this.? Now many here will say run slow, take very light cuts, etc.? When you have a larger lathe to use, why try the Unimat, unless you just have to

Re: Machining 1018 Solid Steel Bar
You didn't specify the length of the part, but it sounds short and stubby so you should be able to hold in reversed jaws. Note:? Jaws must be reinstalled in the correct order in a scroll type
