thanks again for replys..actually thought about making new screw an nut ..m5...but being long an thin would be a nightmare...friends Colchester has no steadies...one optionwould be to get aspare screw an nut for
one of the mini lathes available..tho they are legion...!....would put dials out, but I dont really use them..saying that, they probably to large anyway..clearances only permit about 5mm...hmm...more headscratching....

thanks again for help..not a standard m5 is the thread..tried several bolts..wont even go in one thread...cannot photo...no camera...wonder if its possible to contact leinin themselves..though metric is 60 degree thread, have suspicion it might be 55 or less..friend has some screwpitch gauges..might try them...

thanks for replies....those pics are of the slide I have...o.8 pitch it seems to be...all clues point to the shape of the thread... dont think a tap is available...screwcutting
is out....tap could be
made possibly...a
shadowgraph would be ideal, but no access to
one at mo, so its a bit more headscratching for me...thanks again

thanks for all replies..sorry I messed up my post..typing on small screen...I thought ml2 pinion was 25dp ,a non standard size I believe , have been checking out model car motor pinions tamiya etc..but these are close ,but hardened thro, not practical to bore out at .250" ...the shrink fit idea, not sure would work on such small dia..brazing ,iI would like to try. going to increase shaft to 8mm silver steel ,and reduce end slightly to locate a gear..12 tooth gear quit small, might take a 7mm hole..also working on a idea..pair reduction gears to slow down hand traverse..possible room for these , on front of apron..bag full o cheapo plastic gears, to get the geometry right ,before I buy any metal gears..they pricey..the obvious answer would be new racks an pinion but im not a lottery winner..last note, I scrapped original spindles , new ones en24t...screwcut nose same as ml7, worthwhile, i am happy to receive any comments forthcoming.....footnote..all slides off the lathe have been machined and scraped, new gibs from bronze, used ml7 feedscrews on slides..slow but sure..thanks

often see posts on here ,relating to the old ml 1_2_3_4 lathes..seems there are many still around....often on ebay...though they are all getting worn out..I have two I am refurbishing and the apron pinion gear is a sticking point, cannot find replacement..must be hundreds of these worn out, 1 mod gears close, but not available on imperial shaft, could modify one, but how hold a small gear to small shaft..not sure on loctite..pity some company was not able to make a batch





.




d can cope with most of it..one problem is the the apron pinion, must be thousands worn out, cannot find anything from

Thread: vesconite
24/03/2016 23:52:51
Having read good things, about a newish plastic material, claimed to be excellent for bearings..just wondering ,if anyone has any dealings with this material..rebuilding old ml4, maybe could use this on headstock bushes, to carry the en 24 spindle, phos bronze bushes too hard. though , worried I would ruin the vesconite, if I put the split in it, for clearance takeup, also, might be difficult to pin it to headstock casting , to prevent the bushes moving...anyone tried this material, for the same use...thanks
