    Machine vices all flex when tightened - can't machine square

    Ok thanks again for all the input, I had tried without the rotatable base but that didn't help. I was relieved to hear that this is generally something that many people experience. I have decided to go for fixtures general and specific particularly because I spent almost 2 days dicking about...

    Machine vices all flex when tightened - can't machine square

    I stand corrected I should have said reasonably beefy although judging by the comments about even the top end vices, I have to accept that I will need to account for flex/movement whatever vice, unless I make suitably designed fixtures which I was hoping to avoid because there is a multitude of...

    Machine vices all flex when tightened - can't machine square

    Okay well thanks for the various comments and suggestions, so I want to use the fixed jaw as the reference and therefore it cant be knocked down onto both parallels and as you can see from the attached photos that means over just 2" in the 123 block it is out by 2.5 thou, notwithstanding that I...

    Machine vices all flex when tightened - can't machine square

    So I have a fantastic condition Schaublin 13 mill which is good to within 2 tenths on all axes and the spindle has no measurable run-out but my machine vices just don't seem capable of holding work so that I can machine faces square to each other. The vices in question are a 4" Abwood a...

    Hi I have just been reading a thread where you answered a question about play in the Y feed thread on a Schaublin 13 mill so I hope you won't mind me asking you a question. I have just got one myself and would like to take out the play in my horizontal feed screw/nut, I have the manual but I...

    Hard chroming and re-grinding 2MT tailstock socket - BUT

    Jim thanks for letting me know that "as new" the 2MT is concentric to the spindle and the offset is achieved otherways. Rob -- they did not have a problem with the hard chroming as they have done it before and the quality of the chrome to my naked inexperienced eye looks really good. I figure...

    Hard chroming and re-grinding 2MT tailstock socket - BUT

    Larry I was trying to keep the length of the post reasonably short and not to confused -- so I didnt detail every check that I did. With regard to my reaming since Hardinge state that the tailstock centre should indicate to be .0005 to .001 high its socket must of necessity not be exactly in...

    Hard chroming and re-grinding 2MT tailstock socket - BUT

    Hi - OK-- here is the situation I have a 1994 HLV-H EM ser. no. 14697 which is generaly in superb condition however since I bought it a year ago the 2MT taper socket in the tailstock spindle was suspect (chattering badly when cutting between centres etc) and sure enough a blued centre showed...

    HLV-H Oiler replacment

    Er sorry scrub my previous comment I thought the HLV-H was going to be the same arrangement as my old HLV-BK but it isnt I checked on my new HLV-H and the 3rd mounting hole for the travelling steady is further forward on the carriage -- so quite what that plugged hole in the oiler top plate is...

    HLV-H Oiler replacment

    I think you will find that the 4th hole plugged with a set screw is actualy one of the mounting holes for the travelling steady. The other 2 holes are on the carriage on the other side of the cross slide (spindle side of the carriage) they are plugged with the same set screws -- purely to keep...

    Looking at buying a Deckel FP3 but???

    Hi an apparently nice looking FP3 is coming up for sale at auction but before I even go to look at it (its a couple of hundred miles away) can someone give me the overall dimensions as I have limited space in my shop -- so if it aint gonna fit it would be good to know. If I do go to look at it...

    I am in the process of refurbishing an old Ward controlled spiral grinder and am looking to replace both of the lead screws (table crossfeed and wheeelhead vertical motion) as they are rather worn in the middle. First of I tried to buy 12" lengths of 0.625" dia 10 t.p.i. lefthand thread acme...

    Where on earth can i get a replacement for this bearing

    John:- I refer to them as DU because that is what they are called in the manual for the machine and because the 2 liners in the aluminium cartridge are made of the DU material. Thanks for the link to GCB I spoke to their office in the UK just now -- unfortunately they no longer stock such an...
