Ken you mentioned you don't have a camel back or the like, what are you using when you scrape then?

Did you see the drawing I attached a few post back of the straight edge I made and use? 

I have a more or less a parallel straight edge, the one in the drawing, and a short one I made just like you did for scraping most dovetails.  I do have a very old straight edge that needs recondition that kind of qualifies as a "camel back".  Never own a true camel back straight edge.

I did see it, yes. That's what you use?
It's pretty thin. How does it work on things like inverted V's? Do you use it for spotting? How did you make it? Ground? Scraped? I have so many questions!!

I use it for everything you have mentioned.  Mainly for marking flat ways like the cross slide of a lathe.  The inverted vee's on a saddle, I use the lathe bed to mark or spot the saddle for scraping as long as the bed is good.  My straight edge was made on a fairly new precision MAZAK CNC mill at the time.  Had to use two vises to hold the cast iron bar. We rought it on all four sides, including the cutouts, then went back and finished the surfaces that were scraped flat on a surface plate.  Also had a phosphate coating put on before I scraped it.  Really turned out nice.  Have a couple of issues neither involves in straightness or flatness.

Sounds like exactly what I need. I have no idea how to obtain something like that or machine it.

i too have a homemade straightedge 2" wide x 12" long, as well as a large 5' camelback straightedge
i scraped the homemade straightedge in from a piece of durabar, like Ken did

here is a picture when i was  working on it still.

my straightedge is scraped parallel to .0001"on 2 sides and , one side is a 45 for dovetails

it took forever because i was so intent on making it perfect, don't make my mistake-, sometimes .001" good enough, is just plain good enough


i have a few scraping videos i put up on my channel (scroll down the video list)

here is video 1 of me scraping in the dovetail...

I get mine direct from a DuraBar undisclosed source. 

I you like, I can inquire on a dealer in your area where you can buy some from.  OR cross the boarder into Wisconsin and go to the Durabar outlet and pick it up.  If you let me know what size of a piece you need, I may be able to get you a sample, delivered to your doorstep.

I searched for Canadian distributors from durabars website but it led me to very large companies quite far that seem to only sell large stock quantities.

Well... My surface plate is 18" across, 21" corner to corner. So, 21" is the longest I could possibly blue without finding a bigger plate. I'd say anything around that size I could manage to scrape and rebuild my machines with.


Ken, what would I do without you?

You can scrap in a 24" without any problems on 21" corner to corner.  How thick by how wide?

I don't know 😬
What's standard for a straight end that long?

2x3?
I'd probably mill a 45 on it too, maybe...??
