Any clues please

Can anyone explain how to put pictures on to the site please.

Had to give in today and light the wood burners ,starting to get a damp feel now,grrrr more work ,but must admit its nice

john

Thanks clive,yes can se it will not be perfect but for what l get up to am sure it will do for now,the money you paid is even more now,at the end of the day when the funds are there maybe its time to to get a er32 or 40 back plate collet chuck and and make a back plate for it,but that will have to wait,so for now the block way is the way that l will have to live with,even if l had a sleeve say in mt3 ,an a mt3 collet chuck ,as jason put me right on am stuck with short work holding,so the chuck version with back plate is the way to go long term,or l get very brave and buy a collet nut and have ago at making a chuck that screws on the spindle,but then thinking about it the southbend will not cut metric ,so full circle its the back plate type,will have to keep looking for a back plate with the 2 1/4" x 6tpi thread,anyone got one?

john

Getting more confused by the hour

Yes jason it is a short taper,but in the past have looked at this problem ,and with help from the southbend forum boys some say a 5c fits then others say it will not fit all the lathes,it turns out that southbend had a funny turn and put there own taper in the spindle on some lathes ? mine is 1942 and with my luck its one of them ,never mind l think that l will be happy with the block set up,at the end of the day where do l stop spending.if my collet set will do the mill plus myford and the southbend l can ask no more,if fund allow in the future then l my well add a er32 or 40 set of tooling ,we will se.

john

The lathe is a 14 1/2" x 16" with a 2 1/4" x 6 thread on the spindle ,whenever l need to turn between centres l put the centre in a chuck ,the taper in the bore is not a 3 nor 4 ,have in the past had a go at making one but could never get it right,so have got used to using it like it is,like l said there is some sleeves to be had in the states so it is then mt3 but the cost is silly.Over time l have got some smaller chucks for it so it makes life better working with smaller stock and with adding the collet block l will be happy with that set up ,plus the ml7 has been rebuilt so happy times ahead l hope.

john

No chris its never came with that ,plus its got a funny taper in the spindle ,think you can get a taper from the states to make it mt3,but they do not always fit,plus dam silly money.

But thats just the ticket jason ,have a spare smaller 4 jaw chuck for the lathe,so the block can be clocked in and stop in the chuck ,just put the chuck on an off as needed,may as well get the most use out of the collets when they come,oh well more money to ARC monday ,but do feel that l am getting there now,with all the help.

john

Can any one give me the dia of the stevensons collert block please,,came to me that one of them clocked up in a 4 jaw chuck ,would make a cheap collet chuck for my old south bend ?,just a thought

Can se where you are coming from with the myford an milling ,mind l did try a bit of slitting saw work in it and it was great,just took my time etc,but will be more happy when have collet to hold the tool.

john

I have a catch plate that fits the atlas ,if that is any good to you

Out of interest how many good people are milling on there ml7 lathes or other type,did have a play with mine ahead of getting the collet holder here ,and yes l should not have used a end mill in the chuck,but looking at it l can se it will be good for small parts to be milled,as my mill is on the large size,so any pros an cons on this one please.

john

Mind from what you read ,some of the cheaper 3 jaw chucks are not that great,After placing my order l thought that the mill could do with a clean up etc,then it stuck me the new collet chuck has a m16 thread for draw bar,nope a m16 will not go down the spindle to tight ,after sulking and moaning an why did l not check before buying ,so have made a plug with the m16 thread on it then a m12 thread in to that,when the chuck comes and its as good as they say ,l will remove the plug an loctie it in,oh well it will turn out ok in the end.

john

Well with thanks to the other members on here and the great deal of help from jason who has gone out of his way with his help ,am now sorted out ,and orders have been placed

regards to all john

If its any help ,when l was into car dash boards and have done a lot of them ,l used to put them in the green house after painting and never had a problem,but the hycote brand is very good.

john

Well l am going to be brave and place an order for the bits in the morning, again many many thanks for all the help,and a big thanks to jason.

john

Hi jason yes the back plate way will be nice ,but am trying to spread the cost it seems its cheaper to buy a set of er25 collets with the holder than without the chuck ? but will get a back plate set up when the funds are there,l am well over budget this last few months with ml7 repairs.

john

Hi gray, yes can se where you are coming from ,but the main thing was to get the mill on to collets, instead of just using the clarkson type as the cutters are pricey compared to the straight shanked cutters etc,so l would still need a set of collets and as they come with a chuck in the set ,l may as well have the mt2 one ,so that l can use it on the ml7 if needed ,hope that makes sense.Plus another thing that l se going to the collet system is l can make up tools like gear cutter an slitting saw holders.

john

Morning all,well had a sleep on it and more looking + reading posts,the plan is next week go with chronos and buy the er25 collet chuck with the bt40 taper as my mill is nt40 and also buy the er25 collet chuck set with the mt2 taper,that way l can use the collets on the mill and the ML7. I think l am more happy with dealing with a uk firm over this tooling and hope my luck is in .

john

Many thanks for the help ,my feeling was that if it no good then its better to deal with a uk firm ,have never used them before but chronos do a set and they state that the ones they sell have a run out of no more than 0.015mm,and the price is good,so will sleep on that one ,you have been most kind.

john

Looking ahead ,l am thinking of buying a mt3 collet chuck set , now the cheaper set that l have reading etc about seem to have more run out trouble with the er32 type and the er25 seem to be better ,any feed back on this please,l know that with the cheap sets you get what you pay for,for example the banggood ones are cheap and the rdg ones double the price ,but are they worth it ,its a mine field to know what to buy,so advice etc would be great.
