wohlhaupter up4 boring and facing head

[scotplant]

hi been a while since i posted anything, just been browsing site as usual
just bought a wohlhaupter up4 boring and facing head off of ebay.
but i can't find user manual on internet, all the one on there have buttons on the outside of collar, mines has 8 buttons on top of head.
anyway, my question is, it has a no3 morse tapered shank on it, is this safe to use without a drawbar?? my mill has int40 shank.
its a nice unit but suspect it to be very old and i'm scared to try it in case i wreck it
i,ll try and post some pictures tomorrow.

cheers
Tom..

Of course it needs a drawbar!! If the current shank has no threads for 1,the owner didn't know what her was doing. That is a very fine make,by the way.

sorry!! should have added that it has a drawbar thread but i have saw some with morse taper and a tang, may have been smaller ones though!
is there a morse 3 taper to int40 adaptor with a hole through it that i could make a drawbar to use with the boring head??
hope that all makes sense to someone

The shank on most boring heads can be changed. If yours cannot then a straight sleeve can be installed. http://www.use-enco.com/CGI/INSRIT?PMAKA=214-8709
This will work if you can accomodate the 1 1/4" OD

I was at IMTS this year and priced one of those heads and it was over $8000! They must be a whale of a tool! This ol' boy isn't buying one!

Hello Tom,

I have an original manual which covers Up1 to UP3. It's a bit grubby, but still legible. If you think that it would be of any use to you, you can have it FOC. I would be happy to post it to you as I'm in the the UK. Let me know if you want it and if so, PM me your address etc.

Regards, Ian.

Some of the older Wolhaupters have a fixed shank.

Here's my UPA3 with fixed 4MT taper, with a 4MT-40 taper pass-through adapter. I made a male/female spigot/pull stud, whatever you want to call it, to match the thread and length to standard 40INT tooling.

I don't know what the big deal about their being able to bore a taper is. I always managed to do that

[scotplant]

thanks for all the links etc. unfortunatly all the manuals on the net seem to be for a slightly different type of boring head.
i think mines must be quite old! dont know is it has reversing capability or not??

i think that it maybe a no4 morse taper not 3..but it has a 14mm drawbar thread.
can you get an adaptor to int 40 with a through hole that is fairly short so i dont have too much overhang out of spindle??

whats the spigot like that you made Tim?? could you post some pics??
any idea on what this is worth?? its in good condition for its age..
thanks again

here are some more pictures of boring head..

it doesn't seem to have the feed button mentioned in the other manuals, just a fine adjustment screw in the side.
figured out that if i push in 4 pins in the top it will feed out, then push in the other 4 pins the first ones pop back out and the feed reverses, so i dont think it has automatic reverse feed!
anybody got one of these old style??
Tom.. ps sorry about the size of pictures havent figured that one out yet..
