Rotating Table

Anyone know the correct procedure for mounting the indexing disks to the rotary table made by Soba?
This is what I got
**LINK**

The instructions make no mention of how to do it

I have tryed to undo the bolt from the center off the hand wheel
This one


I have also removed this grub screw


and it still wont budge, I have bent one of my allen keys trying to undo this bolt.

No simple allen screw, RH thread, you undo the screw and the handle pulls off a keyed shaft.

Try whacking it on the end then undo it. They are not normally a problem to get off.

Sorry .don't know that particular table..

1 is there another grubscrew hiding down the grub screw hole?.... has been known

2.maybe try locking table and turing hand wheel to unlock it from allen bolt in center of wheel..like slackening bolt by turning nut..

handle maybe keyed onto shaft or on taper..so 2 might have no chance...

If torque won't do it try shock or heat...I suggest freezer spray...then boiling water..trying to keep rest of table dry...

best of luck.

The grub screw only holds the dial, nothing to do with the handle. handle is keyed onto the shaft, no taper involved.

I have done loads of these when converting to CNC but Ian seems to just have a tight bugger.

Loosen the screw in the middle of the handle say ome turn and then give it a tap with a copper hammer or similar to break the taper free, Mine was a bit tight the first time I took it off.

The dial on the side is also just a standard grun screw that lets you zero the scale

It's not on a taper, it's a parallel shaft and key. If it won't budge when you remove the central screw use a bearing puller.

Read the OP.

He's having trouble undoing the screw, NOT removing the wheel.

Hi ian

my manual instructs you to remove the centre retaining screw and washers on the handle. I can email you a copy of the manual if you don't have one. My manual came via this forum as my table didn't come with one.

I notuced that when mine was first taken apart some time ago, the "blacking" on both the bolt and washer was quite thick and tacky, but no impediment to being undone. Long reach allen key had more than sufficient leverage. Under the standard grub screw on the dial has a copper disc under it to minimise damage to the shaft under the dial, not relevant to the dividing plate issue.

Grizzly G1760 Manual for Dividing Plates will supply all the details.

Ian,

Further to the comments by JohnS and KWIL ...

If all else fails; it may be worth locally heating the screw with something like a Weller Soldering Gun.

Ian,

When you have overcome the present difficulty [and if you are so-inclined] ...

This looks a neat way of attaching a Stepper Motor

MichaelG.

Have a look at this LINK it won't help with the screw problem but it may give you a insight of how the indexing plates fit.

Thanks for all your replys, 4 swift tap with the hammer and the bolt came lose by allen keys own weight.

Now know how Thor feels, the power off the hammer

Ian

If you cannot fix it with a hammer you have an electrical problem.

Has anyone removed, or does anyone know how to remove, the MT2 bush in the center of the (similar) Vertex offering?

Thus far, 'gentle aggression' (i.e. hitting a drift) from the rear of the rotary table, without any dismantling has failed to move it. A search of t'internet hasn't turned up anything useful, but maybe my search terms are not ideal.

Phil,

Yes I have and it took a fair amount of pressure, you have to make sure that the face of the table is firmly bedded onto something unyielding but with a hole large enough to clear the bush.. You are trying to accelerate the bush but you do not want to be moving the table as well. If that does not work then you must arrange for a press to push it out.

You could also make an extractor with a threaded round block behind the insert and draw it through the table and a block with plate on top, on the top of the table with a larger hole than the bush, with the aid of a long bolt or threaded rod.

If at first you don't succede, get a bigger hammer! Ian S C

MIchael, in the days of plug-in valves a good thump was often effecfive in making a recalictrant TV some back to life

I like the idea of the weller. I was going to suggest a red hot allen key.

For future reference what was it you hit? the key, the bolt, or the handle?

Bazillions I hit the bolt, I think it nocked the hand wheel in ever so slightly and put the Allen key in and the weight of the key turned the bolt 1/4 of a turn
