Thread: Sine Bar

I am on the hunt once again for my BIL who needs a 5" sine bar. I looked at Ebay and the only source of these things seems to be India and I am not sure how orders to India would go at the moment besides quality control issues. I looked at Australian sources with no success and thought one of you guys might know of sources in Oz or China that can supply it. There are some in the US at reasonable prices but the freight can be a bit exxy. Any help would be appreciated.

Hi Chris, found a couple on EBay https://www.ebay.com.au/itm/26247855....c101195.m1851
It's in the USA, cost is about $60 plus $20 postage.
I believe most of the items from India are on a level, or better, of what comes out of China.

Thanks Kryn, my major issue with placing an order from India is the current problems with COVID and whether I will ever see it.

DSCN1114.jpgI've got a couple of 5" if you're interested. I could deliver for $50. I'll look now & send a photo.

Edit; The one I'd sell is the larger one as the other is matched with my grinding blocks & angle plate.

Awesome, that would save a lot of problems. I will PM you my email address.

A sine bar is a piece of square bar with 2 rounds attached to it, the rounds don't have to be 5" apart. You just need to know how far apart they are and have a calculator with trig functions.

Bob, I am just shopping for my BIL who is a toolmaker and just trying it find what he has asked for. To me it looks like a steel rule and a couple of bits of rod would do the job which shows how much I know about it. BIL did not agree when I suggested it.

Hi Chris, Guys,

I have and use a "Wixey" digital angle gauge ! It reads to 0.01 and is 100% repeatable, more than I can say about the Aldi angle finder ! That is supposed to read to 0.01 if you are lucky.

But then again I'm not a toolmaker !

In my 60+ years toolmaking I'd have been lost without a sine bar. They make precision grinding of angles a breeze if you have gauge blocks to prop up one end.

FWIW the scissor action knurler I purchased recently came from India (Delhi)
Ordered March 9 arrived March 22.
Could be different these days.

A big thank you to Snapey for delivering the sine bar to my place today.
