Tapered Gib doesn't look right

[hive8]

So i was about to start scraping my parts for the G0704 mill when i did a check on the tapered gibs, they look not right to me, the look and feel bend... i put them on my granite surface to see if there is light shinning through, and to my surprise they are not flat at all, on of the gibs is bend over 2mm the other around 1mm and 0.5mm.

That doesn't seem normal, from what i understand the whole surface of the gibs has to engage the other surface on the dovetail.

What can i do to fix this other then making a new one ...

Here some pictures sorry for the bad macro photography

Bend the gib strip back the other way to get it back as close to flat as possible then use the surface plate and emery
to get the surfaces truly flat again.

Whats would be good way to bend it back, i don't have a press here, just a table with a hammer. If I need to buy something i can go to home depot, sears, lowe's and get it, they are all local here, i have a grainer and mcmaster here too.

Lots of ways to bend it, I wouldn't use a hammer though.
A hydraulic press is overkill unless you think you'll have use for it pressing bearings or whatnot.
At least get yourself a nice bench vise.

Only Table Vise i have, i guess i get a better one...

This is just a thought, but maybe if you have a couple of 123 blocks or even enough parallels that you could stack into two equal height stacks, then lay the gib across the 123 blocks or parallels, so that it bridges them, with the hump UP. Do this near the edge of the work bench or some work surface that is kind of beefy. Then place a bar clamp, large C clamp or some kind of threaded gradual action clamp over the center of the gib and the other half under the work surface. Then slowly close the clamp to bend the gib back to as straight as you can.

Just my $0.02

Yes what i did was the following... Picture says more then a 1000 words

The quill on the mill works good if you can. This makes it easy to use a indicator to see the hump.

I just gave mine a few whops with a hammer and then lapped it on a flat surface.

I'm currently rebuilding a new NH-145 mill.

One of my gibs was the same way. They bend back pretty easily. I simply put a pencil under one end and press the palm of my hand in the middle. Give it a couple of pushes, and check. If it didn't bend any, put more weight on it, or if you bottomed out, use something taller than a pencil.

Thank you for the reply, a very interesting build thread you have. Like the scraping part of it...

That's a good idea as well...
