Honing a frameback with changeable blades?

I thought that the collective B&B wisdom might be able to help me out with a problem. I've got a French frameback with changeable blades and I'm not sure what the best way to hone it is. If I hone it as per normal, it will start to wear down the spine but that will then give me a different angle for when I hone a different blade as they are not all the same size (some are more worn than others). To get a great edge, you need the blade to be at a particular angle on the hone which is determined by the size of the blade and the spine. What happens though when the size of the blade is different?

Interesting.

I guess you just gotta tape the spine and hope the angles aren't too severe.

Whats the size differences between the blades?

I tape the frame.

Yeah, that's what I was thinking. The difference is enough to make a difference (probably 3/16 or 2/8). Perhaps I'll hone up the bigger blade and see how that goes with tape on the spine.

There is a spreadsheet to calculate included angle on coticule.be.

It is in the left column. you can plug inch measurements in and get the proper angle, but you need to change the tape thickness, or measure with the tape already on.

Tape it

I taped the spine on mine.

I had honing issues with one of them.
Mine is Swiss.... The blade moves in that channel in the frame - it took me a while to figure out why my bevel was wonky.
I read thread where someone said they take the stone to the blade in this situation..

Tape anyone
I tape all framebacks, all of them have more or less softer frame then blade.
