Yes several over the years. Most used are a 2" and a 3", very handy in the vice. 5" good on angle plate set ups.

I have a 10" sine bar free to anyone who wants it, just cover postage. Chris.

I haven't personally, but this series of videos are a good way to pass some time

Stefan Gotteswinter's sine bars

It's easy to get hooked on his videos and I've lost a lot of workshop time doing just that.

Made a sine table with castings and plans from Dave Lammas, it's served me well over the years when called on for a special set-up.


see an earlier thread:   Tilting Table Kit?

I bought two on ebay, a common size 5" and a baby 2", they are beautifully made, either toolmaker or apprentice made. To make one, you would need a lathe, a mill, a surface grinder and a cylindrical grinder, plus heat treatment equipment for the intermediate stages.

Many years ago at work, I found a strange tool in a job lot of stuff they had bought, and one of our apprentices recognised the general shape as being that of a sine bar, but it was not straight. The body was about 5 or 6 inches long and the curve of the body was about a two foot radius. I did not know what a sine bar was at the time, but I remember it very well, and the lad was not winding me up. I posted on the H S M forum about it a year or so back, but nobody had ever heard of a curved one. I don't remember if there were any means of attaching it to something being machined.

I made a 2 inch sine bar a while ago and it was published in the No 280 MEW magazine with drawings etc. I use it for setting the top slide of my lathe, against an angle plate for plates with an angle and in the vice for round and square pieces. A sine table I have made in the past but when at work on huge machines the last one was about a meter square and about half a meter tall. You need a large machine to use a sine table.

Yes I made a 100mm one this makes the calculation easy my version is different in that it has a swivel base, this also makes it easy to set up. I submitted an article to ME workshop but as yet its not been published if any one would like a set of drawings just PM me.

It is nice if it is a nominal number for the centre distance to the rollers or roller to centre in a sine table. But the important part is knowing what that centre distance actually is, then it will be as accurate as possible. Having support side arms to aid in keeping it's correct position is a really good idea. Then the gauge blocks don't need to be kept in place. Of course there are many way's to setting the height for sine tables and sine bars.
