Hi,

Could anyone tell me how to use this tool – although it’s a protractor I’m not sure how you apply this to the piece you’d be working on – ie which side is the angle for marking – do both sides represent the two angles – with it being a vintage tool I’ve not got my head around it.

TIA

Thanks Bernard – that’s what I’d assumed but couldn’t be sure.

Cheers

I have one. It came in my apprenticeship tool kit. I have never used it!

To be fair I think it could be fairly useful.

I would think if you set it to 90 degrees with an engineers square and then see where it reads 90 would give you the answer.

I have one of these and I have not used it much, though it is ocasionally useful.

Mine has a line scribed half way acrosss the “tag” on the end of the arm that crosses the degree scale and this is the fiducial line which gives the reading. It’s not very clear from your photo if the line on your protractor is present or has got abraded away from use or contact with other tools . Might be best to do as Andrew suggests and see if you can see the line or can make it more visible.
