Our First Quick Change Tool Post Install & Testing

Show video

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
