Metabo HC260 Changing Blades

[drillbit]

After changing my blades, I had some snipe issues, since when I have spent hours and hours fiddling with my Metabo HC260 trying to get the blades aligned.

I've watched every video available - including Peter Parfitt's. But they have different models.

Has anyone else got the same model, who might be able to advise on a way to get set them up?

I have been using a straight edge metal ruler to test the travel on the blade, and my understanding is that I should check that the middle, and both ends, move the rule by about 2-4mm.

The problem is, there are 3 grub screws to adjust the height - middle, and both ends. I started by trying to adjust all 3 together, but that way, adjusting either of the end ones would cause a pivoting effect, and the action of rotating the cutter to test the 'travel' would be skewed by the slightest pressure on one end.

I was using a method I found on the web, using a piece of paper under the rule, and adjusting the grub screws to make the blade just touch the rule. But even then, I find that when I test the travel, it's impossible to get all parts of the blade to cause the metal rule to travel the same distance.

I've ended up unscewing the middle grub screw all the way, so that only the two end screws are adjusting the height of the blade. That prevents any pivoting effect while adjusting, but even then, I find that the two ends of the blade don't move the rule at all...but the middle part of the blade is moving the rule nearly 8mm....how is this possible??

If anyone with a similar model could advice on how they do theirs, and what I should be aiming for...much appreciatd.

Well unless the blade is curved or bent that's just not possible - unless the out-feed table you are taking the measurements from is itself warped or curved. Have you checked the flatness, across its width, of the out-feed table?

I've got the older Elektra Beckum version of this.

I usually check that the infeed and outfeed tables are both flat (coplanar?) by setting them to the same height and putting a 4ft straight edge across them. Then adjust the little grub screws on the outfeed table if required. Check it diagonally too.

I take it you are replacing the reversable disposable blades? Make sure that they are seated properly on the location pins as they can slip off easily. Also make sure all the nuts on the blade lock bar are loose enough so they don't get impeded when you adjust the height.

Metabo manual is http://www.metabo-service.com/manuals/1151717264_xx_4809_Sx_Ax_de_en_fr_it_HC 260 C.pdf if you need it (blade changing starts on page 22)


Good luck. I changed the blades on mine last week and it took me a while too. I hate working with cold metal in an unheated workshop (hammer)

I suggest you begin by checking the cutter blades and in feed/out feed tables for straightness that has already mentioned.
The usual guide for the "carry" setting method is for 1, or 2 mm of movement and yet i see, on reading the file sent by andypa that 2-4mm was recommended.
I guess andypa is better qualified to advise you, having "been there" on this one, so make him your'e NBF.
