Our First Quick Change Tool Post | Install & Testing
hey on your bed on your bed how you going guys Kurtis from cutting edge engineering today we finally received something i purchased a couple of months ago the company who manufactures it had a material shortage it's been a long time waiting for this and i keep getting asked the same question why don't i use a quick change tool post well now i can the reason i don't use a quick change tool post i never found one i actually liked i have used many different varieties and different brands and breeds of tool post i never found one i actually wanted to put on my machines i was willing to invest any money into considering i was pretty quick at changing tools out anyway to a standard tool post but i did get the chance when i went down to one of our tooling suppliers to actually have a go at one of these and i really like the features it has i like how solid it is i was able to put it through its paces and decided then this will be the tool post i will put on one of my machines so i'm going to run this and test it if i like it i'll purchase another couple for the other machines now that it's here we're going to open up and show you what it is damn child proof so what we ended up buying was a dorian tools quadra indexing quick change tool post this is a 50n model so that means it's got a five inch body on it this is a 24 position 15 degree increment tool post so every ball that you click around to equals 15 degrees they're made in the usa very good quality we also bought four turning holders and a boring bar holder we ordered four of these turning tool holders these go on the tool post these will fit up to 40 mil tools and we've also ordered a heap of new 32 mil tooling to go with these the reason i've bought 32 mil tooling is my little lathe suits 25 the larger machines suit 32 and i don't want to be swapping my 25mm tools from my small machine to my bigger machine we need to try and fit this to our machine now so there are a few different styles of tool posts different ways of attaching them to a machine you do have the european style which is a bolt all the way through and then you have the american style which is a t-nut on the top of your cross slide my machines don't have the t-nut so that's pretty much just going to go on the shelf we do need to make modifications to the compound on my machine to fit this tool post first thing we're going to do we're going to take all that apart and see how we're going to do it and go from there grub screw holding it righto guys so i got the tool post off the machine ended up taking the whole configuration off because it was very difficult to get in under there to remove certain things like the little brass nut for your acme thread that had to be removed in order to get this compound slide off the rest of the um machine we did end up getting out the main pin that holds the original tool post on it's actually an interference fit inside this bore here and there was just a little grub screw to retain that from falling out there was no way it could ever come out through the top being that there's that little shoulder there but we've got it out now so just sort of do a bit of thinking about how i'm going to do the rest of this whether i sacrifice this piece of material and make this the nut that goes onto the original bolt for the tool post or i make a new one do some thinking have a coffee and we'll have a crack at it after careful consideration if i don't like this and i go and modify that to suit the new one i can't put the machine back to the way it was straight away so i'm not going to modify this i'm going to manufacture a new nut well a new insert that can be pressed back into the compound of the machine that is also threaded to suit the new draw bolt that came with our dorian tool post so we'll get on to that righto guys so we're about to cut the thread for our nut to suit our draw bolt to hold our tool post to our machine being that it was american i assumed it would be a unf i was wrong it's a uns it's 14 threads per inch not standard unf i don't have a tap to suit that so we're going to go through and we're going to cut that thread with a baby boring bar that i have modified because i don't have a boring bar small enough to thread holes that small so let's do it nice righto guys so that went really really well i use liquid nitrogen because i can't really feel a great deal with 150 tons sitting on something it's not really a nice press to press something delicate into anything so that was a two thou interference fit liquid nitrogen was by far the best method for this i don't have a little arbor press which would have been perfect for something like that but liquid nitrogen there's no forces anywhere it's just cool it down slip it in and uh she's locked solid she's never coming out so we're not going to put the grub screw back in there there is no reason to put that grub screw in there at the moment or at any stage it's not going anywhere now we can get on to starting to put this thing back together there's two ways we can actually attach the tool post base onto the compound we can either drill it and dowel it or we can drill and tap and put some bolts in we do have the option of doing either or both i am just going to use the bolts i don't really want to use dowels prefer bolts that way it's nice and easy to remove later on because the positions of the dowel holes and the bolt holes are all the exact same spacing i can use the hole where the dowel would generally go to mark out my bolt positions because it doesn't matter where they are on the tool post the reason i'm not using the bolt holes to transfer the measurements down is the bolt holes actually have a 12 mil grub screw in them for a 10 mil bolt so there's no way to accurately transfer them down because i don't have a 12 mil transfer punch i do have transfer punches that fit the dowel holes perfectly don't have to go in there and do any unnecessary measuring just going to go and mark them out and then we'll get it in the milling machine drill and tap some holes and we can going to attach this part of the tool post to the compound right there so that's where it shall live i won't tighten anything off just yet i'm going to put it all back together righto guys so we've finished setting the tool post up on our front line lathe this tool post had features that i would consider to be more beneficial for me in my situation than other tool posts on the market the reason i went this particular style and configuration is not only does it have four slots for tools to be you can actually index the head around 15 degree increments so there's 24 of them and it can also be rotated back to the right as well as the left where with a standard tool post it can only go to the left this tool holder is a dovetail with a wedge lock i prefer these over other styles because even if you do forget to do up the top bolt the tool holder is not getting out of the machine the other sort of styles that are out there are your multi-fix style i'm not a big fan of them i saw one of those fail and a guy did get pretty badly hurt the bridle that comes around the tool post to retain the tool holder onto it it failed it spat the tool it wrecked the job hurt the machine and hurt the guy operating the machine and he wasn't doing anything out of the ordinary just doing pretty standard work after seeing that i decided i would never own one of those i wouldn't trust that on one of my machines being that i do a lot of interrupted cuts really heavy turning they've got fatigue points i'm a bit concerned about those in my opinion they're a light duty tool post that's why i went with the dovetail style all tool posts have a height adjustment so you can lower the tool down to your center height lock it into where your center height is after you work out where it's going to be from your tail stock or your chuck whatever you measure from you then lock those two up and that's it your center height is set they never ever change no matter how many times you drop them on and off they're always the same another feature that not many people are probably aware of is your digital readouts actually have the ability to remember tool offsets what you can do is you can have all your tools set up in your holders providing you don't pull them out of the holder itself you can set your tool offset in your digital readout and it will automatically give you that tools offsets as not all tool profiles are the same i wouldn't have probably ever set up that feature on the digital readout with my standard tool post as i used to change tools out of that quite a lot so in order to set your tool offsets the way you do it or the way i do it is i use one of these little touch off pads so this actually illuminates when you touch it and the way i do it set that on the chuck and bring the tool over to it so we touch off on the center so we're going to go to our sdm we'll zero our y axis for tool one now we've got tool one set in the y we haven't set the x yet we'll back that out of there get it out of the way we'll change this tool holder chuck this one in we'll bring it over and set it up you can see the tool is not the same so we go up the tool too and we'll zero that one out now i know if i put the other tool back in and run it back up to that point and go to tool one it should be in the exact same spot if you are setting tools up you will clamp the tool in that way everything's nice and tight you'll get a true measurement but we're sort of just demonstrating on how this works the other machine has a digital readout on it which also has the ability to remember tooling if i like this tool post i'll order a second one to put on that machine and then i can set all of these tools in that digital readout as well being that i don't just use four particular tools for any given job i'm sometimes using six or more i don't have to change out tooling from their holders i can just simply swap from this machine to that machine one of the other concerns i have with a quick change tool post is rigidity so what i'm going to do is i've got all this set up now so i'm going to throw a bit of material up in the chuck i'm going to take some cuts and just see see how it performs so the piece of material we're going to be using for testing today is a piece of 100 mil 4140 high tensile material pretty standard pretty on par with what we use here in the workshop on a daily basis right so our first cut was a three mil depth of cut six mil overall took that no worries at all we just did a four mil depth of cut so eight mil overall and it performed very very well it's pretty much on par with where the other one would land so that cut then that was a six mil depth of cut so 12 mil overall 335 rpm at a 0.25 feed rate it has exceeded what i was game to do with my standard tool post very happy another good test is going to be when i start using my button inserts the sheer size of them and the cutting area the cutting surface is so much larger if the tool post is going to give me any sort of grief it'll be when i'm using a button insert i haven't got my new 32 mil holder for that yet so you'll just have to keep your eye out for the next video where i'm using it just like to say a big thank you to arthur from live tools he was the one that was able to organize getting this from the states for us they are very very good quality they're a lot better than a lot of the other [ __ ] you buy out there on ebay and whatnot so if you're going to do a tool post and you can afford it spend the money buy something that's going to last one of these will set you back a fair few thousand dollars this tool post has all the features i wanted and more so very very happy with the tool post and i can't wait to put this thing through its paces no oi now we can point the camera in the right direction now that that thing over there's been revealed so it'll be a lot easier to try and do what we do without trying to hide [ __ ] we've got to hide that one so what we ended up buying was a dorian tools what we bought was a dorian dorian tools oh my god what we ended up buying was a dorian tools quadra indexing tool post quick change [laughter] oh [ __ ] just do we'll do one thing at a time because that's kind of what you can manage yeah [giggle] righto guys so we've got the tool post set up on our most often used lathe that sounded terrible [laughter] righto guys so we've got the tool post set up [laughter] righto guys so we've finished setting the tool post up on our front front line lathe [laughter] [laughter] very very happy with that yep [giggle] okay what else oh [ __ ] [ __ ] oh [ __ ] me [ __ ] hell [ __ ] oh my lordy he can't help am i starting again that handled that piece of piss instructions don't need them so if i don't like it i will call my tooling supplier tell him what i think of his tool post and him and then i will put it on the shelf and never talk about it again and for some unknown reason that's a 10 mil bolt and a 10 mil dowel but this came from banana land what's that six times 40. 240. it's 240 thousandths of an inch in one hit what [giggle] i don't understand i need my bananas this feels familiar [nervous laugh] ready no huh here we go [ __ ] [ __ ] dog something's binding Homeless must've chewed it NO oh my god oh my god you [ __ ] hey mate what's happening they broke a ripper really i'm going to move back woah buddy jesus [Kurtis humming] ya'll ready for this NO on your bed go lay down on your bed no no no on your bed go lay down
