    Maybe the tools in your case make the tradesman, sorry.

    I can't speak for anyone else, but I normally stone sharpen my HSS tooling after grinding to shape, so I doubt the "quality" of the bench grinder used would have much of an impact on the final result.

    Uploading a video now guys i got the main cross slide sorted and tighten up it was a merry go round with the combination of 1/4th a turn to either of 3 bolts on the back of the cross slide its tight now

    now when i take a deep cut its automatically cutting a angle when all i want to do is cut across side ways to reduce the diameter, when i take small 1mm OD cuts (.5mm on the dial) it cuts great when i up that to cut 2mm OD (1mm on dial) it cuts at a angle anyone know which adjustment i need to make? video coming now of the whole ordeal

    i loved this machine the last few days but its wearing off I'm not good at adjustments i just wanted a lathe to use strait away

    Hi Gazza,

    The part that runs on the bed of the lathe is the saddle ! The cross slide is the bit that sits on top of that and the top slide is the bit on top of that ! All three parts will have adjustable gibb screws. If you have play in any of those three parts it will affect the accuracy and finish and I do wonder if that has anything to do with pulling the work piece out of the chuck jaws.

    HTH.

    Every cheaper lathe needs adjusting, jus percivear with it. Even my 12x36 lathe needed adjusting, so it's not just little lathes.

    I just watched a god video on how to adjust the gib screws i think i have it worked out now but still unsure why my lathe was cutting strait than on a angle

    here's the video i aint winning no beauty contest guys https://www.youtube.com/watch?v=rdNKSIx4OZQ

    You'll notice it was cutting on the way in and one the way out while facing

    As I said earlier don't go down the same path you did with the welder, every time you machine something, something usually needs to be adjusted even if it is the same operation and same material.

    Pipe this is much different to the welder... i bought a UNIMIG Razor 200 welds so much better than the Italco but mig welding is not my thing I'll use it when i need to glue something together much rather use the UNIMIG TIG as i did yesterday on 6x6mm steel without melting it into a small of crud

    I just need to work out what does what to what on the lathe if that makes sense, get this on the back of the saddle there are 2 bolts these are called lock bolts when u screw these out they lock the saddle and it doesn't move and when u do them up tight as in lock bolt... they free the saddle than there is a middle bolt that is the adjustment bolt if u screw it in it locks the saddle if u screw it out it allows the saddle to move

    so its kind of a reverse reverse thing its bloody weird and i couldn't work it out i think i have it now but i am not 100 percent sure also we are talking 1/4 1/8 a turn of the screws and it locks or unlocks i need to find that right combination

    Tightening gibs is a finical thing, also one person's veiw in adjustment is different to another so I have found visiting other home shops. I like them firm, but not binding, remember to oil them before adjusting as that matters.

    I have had my 12x36 lathe since new in 2006 and no wear areas, so I must be doing it right (or just not using it enough lol) Just keep at it if you're finding movement to adjust it out.

    Went out to the shed and took a look at the lathe i started by taking off the tool holder than i took off the top slide, i lent over the machine to reach the 3 adjusting bolts and finally worked out how to use them the booklet says to move the middle bolt 1/4th a turn this is to much i had to move my bolt probably 1/15th of a turn once i narrowed it down the turn was so tiny i was stuck between that 1/15th of a turn for a sloppy carriage or a tight carriage the lead screw handle on the end of the lathe to the right is a tiny bit tight but i can manage

    i just machined the piece in the video took off 2mm on both sections and it worked great still a little bit of a bevel there on the piece that's how much of a bevel it cut in with the slop in the carriage

    i moved on and used the ebay video on how to adjust the slides and the gib screws it worked perfect i got the in/out slide working beautifully smooth no slop at all and its nice and tight

    I'm not sure where your going with this but he will get a great edge on that grinder for a simple lathe tool.

    I would sharpen my chisel with it then stone it, from a kid I don't remember my grandfather using anything other than a standard 6 inch grinder to sharpen chisel's to perfection after a little stoning. They cut paper no problem or you finger.

    A few weeks ago I got a job in my new home town, dragged out one of the old markets score 6 inch bench grinders with it's factory wheels and sharpened a new piece of HSS no problem. Got the oil stone out and the eye glass to finish it and it cut perfectly as I expected. As you have read the guys on a budget, but his grinder will do fine even if it's a little slow.

    We all start somewhere, but you don't have to start with a tool and cutter grinder to sharpen a simple HSS but for your lathe.

    That's what this forum is for, to help other members with what they have got, and help the succeed.

    Hi Gazza,

    The power of the grinder has little to do with how accurately it grinds, more to do with how much metal it can remove per revolution for a particular grit size.

    Ah ok it does take off metal off the hss but i understand hss is a hard metal to grind and u dont want to over heat the steel, that new tool bit i was grinding the other day was taking forever so when i grabbed the old tool i used tge edge of the stone worked much better at removing the material than on the flat side

    How are u guys picking up your shavings vacuum? I have millions of shavings everywhere!!!

    For anything magnetic I use a magnetic pickup tools, for all the other I use dust pan and brush of the shed vacuum.
