Thanks Steve. That's very good information for getting tooling for my Chinese mini lathe. I'm
using the standard tool holder that came with new. I really enjoyed to see your milling process on the lathe.
A very sensible way to use the ubiquitous large-lathe tools on a smaller lathe. Why didn't I think of this? Thanks, Steve.
LOL!! I did the exact same thing last week but used a mill to reduce the height! There is no doubt that using a larger tool makes for better cutting and is more sturdy. Thanks for the video!
Good information Steve
I have milled a number of these tools down and have today used the blue nano coated inserts. I found them to be superb in the way they cut and long life.
Too, one can always hog down the turning tool holder with a bench or angle grinder to save the milling tool edges for the final dimensioning operation, but again, another fine bit of ways and means from you Steve. ☺
Great video Steve, I've a bundle of oversize lathe tools and I'll be able to cut them down now.
This is an EXCELLENT demonstration and video, Steve. It is exactly what I was looking for and I believe many smaller lathe users can get inspiration from such a demonstration as 10/12mm tool holders are much more common than 8mm ones on ebay or aliexpress (among others). This offers a broader range of choice at the time of buying toolholders plus increased rigidity once mounted on the tool post, all beneficial. Thanks for sharing !
Hi Steve, another well constructed tutorial, I have a swag of old tools for a larger mill but as a newbie I had wondered if it was possible to machine them to fit my smaller tool holders and you explained that really well and will take on that task the arvo. I also received all the parts for my tool post drill asssembly so will be tackling that this weekend. Keep the great videos coming, all us keen newbie, aspiring machinists out here really appreciate your comprehensive approach.Oh yeah, really appreciate the links you attach below each video foreasy reference. Regards from AUS, Gordon
The WNMG style is my Go-To tool for most of my garage shop work. Glad you mentioned the 6 side insert option with 0 rake. I have also milled some of my AXA holders along with some eBay very oversized tools.
You are pretty fearless when it comes to trying new things.
I like it.
Thank you for the video Steve. I too have been keeping a copy of the papers from Amazon and Bangood for each of the tools....sure helps when you need inserts or whatever. Thanks again.
Great info as always. My girl friend say's I do a very convincing imitation of Mr Jordan. Particularly when I say "Myford ML Seven"
Hi Steve,
That’s how I milled my larger tools also except I used a carbide endmill in the collet chuck. I have just recently got one of their 50mm 4 insert face mills on a mt2 arbour that will go into the headstock, I figure that I could use it as a single point or dual point fly cutter or as a 4 insert face mill for mill work in the lathe. Will have to see how that works out.
Thanks for the video.
Cheers
Raymond
Well once again I've learned a lot. Thank you Steve.
Steve I've done that my self, what I prefer is to mount the tool directly to the too post. In the states we use a lot if the aloris style quick change blocks so the dovetails are somewhat simpler to machine. It could be done with your style post, but reducing the thickness is easier, I ran into loss of travel so that is why I direct cut dovetails in my large tools. I have some videos on my channel demonstrating how I do this. Also a little closer to you John ( Doubleboost) has done the same
Good job
Thanks for the Bang Good links. Have just ordered using your links. My first ever BG order after many years only on eBay.
Do you have any videos on knurling and the different types an best methods for the mini lathe or myford? I really enjoy watching the videos very informative. Thanks for sharing!
I just hold 'em by hand when I turn. Who needs all that milling crud.
Hi Steve. Yes I to have one of those cutting tools that you milled down from Bangood as well and they are as you say a well made piece of kit. I went a different route to you though and made a custom tool holder to fit my quick change tool-post on my mini lathe. I needed to cut out a square in the tool holder as well to allow the tool to recede into the tool holder, Without doing that the mini lathe is only capable of turning about 20mm diameter due to its lack of travel. I have the new tool-holder all done and dusted now and I am very happy with the results, but I have belt issues on the Chinese mini lathe atm, so though it is centered and ready to go, I need to adjust the belt or change the belt and pulleys and adjust before I can use it. I don't unfortunately have the luxury of 2 lathes :) but I do have a mini mill which has just had a thorough work out :) Good work as always Steve.
Hi Steve Thanks, That sound really good allowing more travel for the tool. I changed my pulleys and belt for a set I bought from Ebay in the USA. Its a reduction set that reduces the spindle speeds, but gives about twice as much torque. It is great for drilling. My top speed is about 1600 which is still plenty fast enough. The USA set is also made from solid aluminium and the belt is a standard size, unlike the non-standard Chinese one. I have several videos lined up for the mini lathe when I get time. Regards Steve
Wow that set from the USA sounds really interesting Steve, do you by chance have the link? Because I would like to do that upgrade Regards Steve.
This is the one I bought.

Thanks Steve I will need to check a few things, but when I am sure I am ordering the right part I will have one of those sets. I have saved the item in my ebay account though. Many thanks Steve
Thanks again Steve. I have ordered that set from the USA so should have it sometime within a month lol. Apparently my lathe is basically a Seig C2 so I will have to modify the drive pulley, which should be easy enough. Regards Steve.
Hello Steve,
thanks for sharing.
Hi Steve
Great video as usual ... you must be psychic as I have just finished making a similar mod to a 16mm shank tool so I could fit it into my Boxford Dickson type tool holder. I used a Nicecutt PWLNR/L1616H06 External Turning Tool Holder for WNMG insert. I bought mine off AliExpress. It takes the same type tool tips you have on yours. I did this because I had looked at all the videos on line and this type of insert seems to give the best results particularly on hard materials like stainless steel. I milled the bottom of the tool which was very hard but just machinable with a carbide end mill. I have tried mine on all my usual materials and it seems to give a superior finish and a nice short curly chip. I did try it on some En24T and it machines very nicely giving a good surface finish, which is not so easy to get with normal inserts.
John
Hi John, Yes this insert is great for all types of machining. I remembered similar from years ago when I used to set and use CNC machine tools. When I saw these online for such a good price I had to get one. We used to use the heavy duty tools like this for fast roughing out and finishing hardened stainless. For my Myford I think, as the cost of turning tools is so good from China, I am going to get my other favorite tool that takes the 070204 insert and buy it in 16mm to mill down. I like this tool for undercuts for threading and its a common insert. I think next time though I will rough out with an angle grinder first then finish with the end mill. I noticed that several years ago the Chinese tool shanks were a bit softer than they are now. Thanks for watching and for the info....Regards Steve
.
thanks steve
Thanks Steve! Just placed my first order on Banggood ordering the exact same stuff as you listed. Let´s see how many days/weeks until the stuff arrives :-)
THANK YOU...for sharing.
thanx for sharing that with us
Good show
Another nice video, nice review too, waiting for the next one, take care till next time......
The only thing that worries me about Bangood is that there's a risk of getting stung for import duty, VAT and the Post Office's "handling fee" for un-customed goods. There doesn't seem to be any way of calculating and paying the taxes up-front - unless I'm mistaken....
Steve I know that this is one of your older videos but I was needing some new inserts for my 3 flute milling bit like yours. I had been ordering all my inserts from bang good ,but finding that now every time I go to order some more they seem to be out of stock. Some has been out for over a year now. Are you finding this to be the case when you order inserts from them. And if so where are you getting your inserts from now.
Hi Anthony, I haven't used mine for some time now. A lot of things are unavailable now on Banggood. I would just see if you can get them on Ebay if you can. If you find any, let me know. Regards Steve
Have you changed the motor pulley, Steve? 800rpm is fair bit more than my ML7's top speed, which I think is around 640rpm.
+brandoc1950 Hi yes I put the one on that is specified in the Myford ML7 handbook. I think it is 2.5" if I remember rightly. RDG used to sell them on EBay...they probably still do. I found 640 rpm too slow and use the 800rpm for most turning. The other speeds are around 300rpm and 500rpm. Plus the back gear range increase a bit. You can fit the new pulley just by adjusting the belt tension. You don't need a different belt
Cheers, Steve. I have a few pulleys kicking about so I might see if one is suitable. Only disadvantage I see is that I tend to part off at the slowest open gear, so I might need to use back gear.
hi steve thanks again for a good video , can you tell me where to get a quick change set up the same make as yours thanks john
Hi John, I got mine either from RDG or Chronos. I think Chronos was the cheapest the last time I looked, especially on the single tool holders. At first I just bought a set with the toolpost, then over the years just added to the collection by buying singular holders.
thanks steve i,ll check it out

but...this (1 inch dia cutter) will not fit in a mini lathe chuck right? :(
I only use end mills up to about 12mm on the Mini Lathe. If you wanted to use one like though you could turn the holding diameter down.
Steve, I've just noticed your serial number... Mine is 6760 so very close in age to yours and is undergoing a bit of a tidy up as it's nowhere as good looking as yours.
Hi Robin That is interesting....They soon come back to good condition with a little work. Plus if you get the Myford enamel paint listed on ebay, although a bit expensive, it brushes on really nice and doesn't leave brush marks when dry. You don't need to do the whole lathe either, just the areas that need touching up as it blends in nicely. It is a superior kind of paint.....if your lathe needs doing a bit.....Regards Steve
Steve Jordan thanks. The lathe is generally in good order and the ways still bear the original milling marks so aren't significantly worn. The paint is however so poor it wipes off with a bit of Meths!!! I suppose after 69 years giving the old girl a new coat is the least I can do.
OOps - MWLNR is the tool and WNMG the insert. Still trying to get warm, it is snowing and 0 degrees here.
ive got one of them the WNMG0804 Inserts are not very good you only have to look at them the wrong way an they chip try an get some sandvick or some of the other better inserts they last much longer
+Gareth .William's Hi Gareth I find them excellent and I've used Sandvick and Iscar and the other branded makes. Maybe they wouldn't stand up to .100 thou cuts or machining inconel but on my lathes they work and last really well and only sometimes chip like any other.
Hi Steve, do you happen to have a collet chuck for your mini lathe? I'm wonder if one of these would actually fit? Anyone know??

This one on Banggood should fit judging by the hole configuration, the answered questions and reviews on the Banggood page.

Thanks Steve, are they sending you their goods for reviews now? Maybe you could request one?? I'd happily buy it off you when you are done, if you didn't want to keep it.
