      Hi

      I have the opportunity to buy a Kerry AG lathe, it appears to be a Mk3 , it is fitted with the L00 style of spindle . The machine is in very good condition . Are they are good quality lathe ?

      Does anyone have any knowledge of these lathes ? Doesn't seem to be many of them around .

      Thanks Mike

          If you haven't already seen it, there is a decent write up at http://www.lathes.co.uk.

            Our 'technician' had one … with the nice skew drive on the tailstock … and loved it.

            I only tried it briefly, but was very impressed.

              Hey thanks

              Looks like I am going to buy this lathe !!!! It comes with 2 faceplates and 2 chucks and the plate for driving the dog , no steadies though . Has a spare lead screw with it . Yes it has the angled hand wheel for the tailstock . Quite a stout looking machine . Regards

                Good machine. Arguably the best, and most expensive, of the 5" centre height lathes capable of being bench mounted. As I recall matters it's probably the easiest one to do metric threading on an imperial machine as very little change wheel shuffling appears to be needed to get a comprehensive range of metric threads. However I've never actually done this so may be mistaken. My involvement was through helping a friend rebuild one. Never got to drive in anger.

                As ever there are niggles. The standard topslide dial is too small for no apparent good reason. Some come with full size double dial imperial / metric reading ones on both top and cross slide so there is plenty of room. My friends was a Mark 2 so the threading was via a simple half nut, not a proper double clasp one, so it wears faster and engagement is not as precise. Yours may be the same. Gate change sliding / surfacing feed slector is neat but it does take bit of getting used to.

                Clutch is effective but very sensitive to free play in the shaft. On the MK 2 the end bearing on the chuck side is restrained by a simple sheet steel pug expanded into place. If this loosens the bearing can shift back and forth introducing an intermittant and unpredictable movement of the clutch engagement and disengagement points. The shift is only about 1/8" before other factors come into play and stop movement but it will drive you nuts trying to adjust it out as the mehanism has very little built in overtravel tolerance. Cure is a bolt on cap to hold the bearing in place. The angled and offset tailstock feed handle on later ones is said to be an acquired taste. Some folk consider it lacks feel. Others don't like the position. Hexagon power feed shaft is said by some to be less positive than the usual keyed shaft and claimed more sensitive to wear. That sead the one on my friends Mk2 was fine despite visible wear.

                L00 backplates may be hard to find at ME friendly prices if you need to make up another chuck mount or similar. Cabinet mount version isn't significantly smaller than a Harrison, Smart & Brown 1024 and similar full industrial lathe which are up for heavier work.

                As ever its condition, condition, condition that decides but if its decent then go for it.

                Clive.

                  Hi Clive

                  And thank you for the very useful information .

                  Regarding the L00 back plates, this supplier has them for a decent price . CDCO tools , he has a web site and he ships worldwide.

                  I noticed it has a coolant pump in the cabinet , at the headstock end .

                  Ok I will see how the clutch behaves , hopefully it will be in good shape.

                  The hex feed shaft , I do have a spare one which is a bonus. Mine has the half nut lever on the end of the carriage , rather unusual place for it.

                  Mike

                    The simplest check for wear on many lathes is just how noisy the gear head is. It should just hum and the motor may well make more noise than the gear head under heavy loads. No rattles in other words. This is describing an as new lathe though but is a useful guide.

                    Just add when I was looking at larger lathes and working in the garage this simple check allowed me to walk away from a number with out even looking closer. Next thing would be wear in the slides and a bit of turning.

                    I finished up with a Raglan – no gears but Brum is probably not the best place to look at gear head lathes

                      Only guessing, but does it have a spare lead screw, or is one LS metric, and the Imperial?

                        I think Tony from Lathes UK mentioned that the high nickel content that some manufacturers used in lathe gears, can have the effect of making the gears 'sing' , or appear to be noisy .

                          Hi Ian

                          Gee that is a possibility , but the spare LS looks like it is a 1/8" pitch

                            I mentioned as new because there is a need to be realistic on used lathes. The noise should be more of a hum come whine than rattles.

                            This one sounds moderately worn to me. I tried to find another one that was sold on ebay and the rattles were at a point where I would look the lathe over very carefully and probably find very loose headstock bearings and a well worn bed.

                              A friend had Kerry some years ago,only complaint was that the head stock gears were noisy,over time the noise got worse and as his garage /workshop adjoined a neighbour ,he got complaints about the noise and eventually got rid and bought a Cplchester.

                                I don't think that is anything to do with the make Nigel. I mentioned some one a while ago that had a larger long bed Kerry and it was as quiet as a mouse. His sons were machine tool dealers which probably helps especially on lathes that large. laugh He tried to sell me a Student. That was an excellent example of the rattles which is probably why his sons weren't selling it. – or maybe not.

                                  I was just thinking that one might be 8tpi/1/8", the other 3 mm which is close enough not to notice the difference at a glance, I imagine it would me marked in some way.

                                        It should be well worth the effort of cleaning it up. One of the few smaller lathes with a good sensible head stock bearing set up more less a la Schaublin, DSG, Lang etc.

                                        yes I want one but would guess that it would crush the kitchen cabinet my Boxford rests on.

                                          Hi Michael

                                          The odd looking belt does have the basic appearance of a modern Poly belt, but it is made from a canvas rubberized material . I would say it is the original belt from the 1960's. The V groove spacing in the two Kerry pulley's is very narrow, unlike the poly pullies you see around today. Will take a pic tomorrow , its night time here right now – the time difference !  Cheers  Mike

                                            Been looking for a manual for the Kerry AG mk3 , no luck. The Kerry manuals available are for the larger models .

                                                Hi

                                                 

                                                Well I have discovered a odd thing about the Kerry , maybe Kerry did this for some reason.

                                                There is a layer of cork between the bed and the base . Why ? This pic is from the lathes uk site .

                                                My Kerry also has a 3/16" thick cork gasket as indicated on the pic .

                                                If it isn't cork, then its some kind of insulation.

                                                  Hi Hth,

                                                  This interested me because i too have seen this type of material before, it's an unusual kind of gasket which is kind of like moulded "rubber impregnated cork" material. I have these on a B56 imperial framed motor and i think it's for insulation purposes.

                                                    Hi Michael Thanks for the reply

                                                    Would the cork upset the process of leveling the bed and keeping the bed level . The lathe bed would be sitting on a lump of jelly ?

                                                      Isn't it just a gasket to prevent coolant going down the fixing bolt holes? I set my lathe on a bead of silicon between the bed and the drip tray for the same purpose.
