Degree graduation strip

[sean logieParticipant @seanlogie69385]

My topslide doesn't have any markings at all to tell me what angle the topslide is sitting at . I'd like to fit one to speed things up a bit . Can someone tell me the proper name so i can go looking for one .

Thanks

I have an angle gauge which I got from lidl for a tenner or so. You can probably get them from ebay. The one I bought looks like this one on ebay, but was quite a bit cheaper.

You can set the angle to 1/10th of a degree, which is certainly good enough for me. In fact there was a nasty piece of plastic on my cross slide which I was pleased to remove.

Protractor?

Interesting bit of kit …..

Sean they are not normally "fitted" but engraved on the cross-slide surface with a fiduciary mark on the topslide base. Short of dismantling the lathe and getting one engraved, your best bet is probably to buy a suitable engineers protractor and use it to set the angle, probably relative to a test bar in the chuck.

I made a new cross slide for my lathe, if you have a rotary table it is a simple job to engrave the degrees on the mill with a pointed tool.

Nothing beats a sine bar or accurate wedge to set the slide if you want real accuracy.

That does of course assume that the edge of the topslide is truly parallel to the dovetail slide. Worth checking.

From the title I thought this thread was going to be about people taking off their gowns, hoods and mortar boards.

+1 for graduating the top slide, so that you never have to be concerned about this again.

May I suggest:

1) Remove the Top Slide.

2) Make a Fiduciary (datum) mark on the centreline of the spindle about which the Top Slide pivots.

3) Using a protractor (or whatever more accurate means you have available, such as digital angle gauge, sine bar, rotary table, dividing head, etc) scribe graduations on the Top Slide.

4) Reassemble, no longer have the problem, and have a Happy Christmas.

Me too, although it's a long time since I've worn any of those items.

Seriously how often do you expect to set the topslide to 43 degrees, or 21 or etc. In practice you only require 3 or 4 actual settings. SO make a reference mark on the topslide and when you set it for screwcutting using a protractor or gauge of some sort make a corresponding mark. Any time you are doing a serious angle like for a Morse taper the graduations won't be accurate enough anyway.

edit – I wore my gown a couple of weeks ago at the company xmas dinner. It comes in handy for fancy dress in this case Super Hero member of the Cornish Pasty Eating Squad. (CPEQ is our department name so it sort of fits.) Mortar board hasn't been the same since the mice eat the tassel.
