Walter dividing head

I wonder if there are any members who have knowledge of a Walter dividing head. Model VTHUW4. This is a 200mm chuck version. I want to remove the chuck , but cannot find any obvious way. Before i start diss assembling from the rear i just wondered if anyone either has had one & stripped or has any idea where i might find a manual. Even a parts manual for this or similar model.

Look down inside the chuck, there may be evidence of a screw thread that the plate at the rear of the chuck is attached to. The holes in the plate may well be for a C spanner.

In German but with photos.

Hope this helps. Search under Walter Teilapparat.

Dick H ,many thanks. I looked on the site. With translation i managed to see similar to mine from the rear. The chuck rear has a long taper of which is threaded at the back. This large nut seen from the rear needs taking off. It looks like the chuck just comes away from it's taper then . As a complete unit.

Old mart, the holes in the chuck rear maybe for holding or as there are 6 it could be for simple hex indexing.

The one in the German picture is slimmer & does not have the indexer on it. Many thanks guys. Will have a go tomorrow. I bought it on photo's for not much money, really cheap. With intentions of using it on my mill. When i saw it i realised it must weigh half of my whole mill. It took 2 of us to lift it out of my van. So no use.

Have a look on you tube, there are several restoration videos of Walter dividing heads. Might give you some useful tips.

I have done that but found none that were the same. The problem is the Walter models that are on there are the adjustable pitch ones. This one is either vertical mount or hor. Thanks though Alexander

Are you saying that your new powered Z axis motor will not cope with the weight of the dividing head?

Not a chance with this one old mart. It is way too big. I bought it along with some other nice Mitutoyo height gauges at an auction. I am taking the chuck off for 2 reasons. 1: to give the whole thing a good clean & repaint.. 2: so i can lift it on my own. I did not want to mess with the internals as it seems to be in perfect working order.

As it is i can barely slide it around on the bench. I had to buy unseen & just from pictures. Sadly i scaled it wrong .

I should get a good return on it. . I do not regret getting it as the price was scrap metal money.

I think it will unscrew using the holes in the plate at the rear of the chuck. There should be no requirement for dismantling the whole thing just to get the chuck off. The chuck is obviously a rear mount and the heads of the screws holding it to the backplate should be just visible, probably countersunk ones like the others in the picture of the back.

My Soba 6" rotary table fits on the TS bed very well, lining up with the tee slots perfectly, they are very handy things at times and not so heavy.

If you end up selling the heavy one with the chuck, leave the chuck off when the buyer collects it. That one would fit a Bridgeport or bigger mill.

Thanks old mart. I may give it a go this evening. There are 3 fixings visible but unaccessible This is how it comes off. Pictures from a German forum. Kindly sent to me by Dick H. Just to add, the previous pictures i posted show a large female hex at the rear. This is how it is fastened on. You are correct , it will probably be ideal for a Bridgeport or larger mill.

It still makes no sense to me, doe's that female hex push the backplate spigot out of the hollow spindle? The pictures don't seem to show any threads, or the hex on the spigot end. Is it a taper fit?

Got it out. Yes the taper is threaded at the rear. Pictures explain all. Not sure what the taper is. It is very large, maybe just what they used.

Steve.

That would have cost somebody a few bob when it was new !!

Here’s an out-of-the-box thought, Steve:

It would make the basis of a very chunky small milling machine

... Just add a vertical milling column and put a small X-Y table on top of the rotary.

That's an idea. I think it will be going on ebay though at some point.
