herbert junior surface grinder

hello all , its been quite a while since i posted here but ....
recently bought the above machine , in pieces . after assembling it
find a problem with the knee jib strip ! does anyone have one of thes
machines they could take a picture of ? to use the m/c i have t
tension the lockscrew to take the slack out of the slideway on the kne
, but this isnt ideal as the lock has to be slackened to put a cut o
,and this allows the whole table assembly to move! so if anyone ca
point me to a "users book" or drawings or photo's of the machine o
could share their experience of this machine with me please ! (ive onl
used a j&s 540 to date and that was 10 yrs back) cheers ke

Hmm, the other side of the gib has adjusting screws. Right? Why not adjust them. The lock screw is for locking only.
Or what did I misunderstand?

sorry i'm not good at explaining ! i hoped the gib strip would tighte
upwards , thus bearing on the slideway , but its slack ! by using th lock screw and the grub screw i can make the gib bear on the slide bu .. it works but not correctly ! i believe the bottom hole and gru screw to be an "add on " as i would have expected the same at the top so i'm wondering if i can shim behind it with a length of gauge plat !the top pic is with the lock on , the middle is lock off and showin the movement i cant adjust out and the bottom pic is from the same sid but lower down , showing the hole with a grub screw in it

sorry to keep pestering but ....8-) right , im trying to shim behind th
gib strip ,to make the job lot thicker so the adjustment screw works anyways , i had an old rusty rule from an old broken comination set thought i'd modify , i cut the shape using a demmel type tool ,but whe i fitted it i found it to be a few thou too thick. . so i shortened th shim to fit the travel of the grinder and then ground it . but whe released from the magnetic table its sprung !! if i turn the shim roun the magnetism of the table will straighten it . if i now grind the othe side whats my chances of the finished job being flat ? suggestion please !!! pretty please even !!

It might, but does it really matter provided the spring pressure doesn't exceed the capability of the ways oil film? The adjusting screws will provide the hard limit and the gib will sort of float on the spring.

movement i was having problems with !

hi all, i dont supose anyone will but... im in need of a wiring diagram for this machine, i bought it with it just plugging into the converter i use as the seller had disconnected all the internal wiring! i do not like using the machine in this way but aren't clued up enough on the wiring to do it, i'm almost there mind and want to check my wiring to the diagram!

willowkevin was zeer hard aan het denken :
Hi Kevin, as answered privately, I send you some pictures of the wires. The manual doesn't show these, only the parts. Meanwhile I am inspecting the interior of the 1959 Hacou permanent magnetic chuck, delivered with the grinder. It seems to have lost some of its power.

Try the Engineers Emporium. They sell a parts manual copy with detailed exploded views.

hi, yes the engineers emporium do do the parts list! its a very handy book!- Dirk, some pictures of the wires would be good! i had posted an ad on home workshop, and a very helpful bloke sent me an old contactor unit, with the wires still intact! but.... there's more wires than it needs, so now i have to work out what goes where!!!!
fingers crossed it may work for christmas!
