Could someone give me some answers?

OK my phone playing up uploading video but I opened one I test sealed and it almost blew my hand off. I'm going to try some more of the test bottles tomorrow.

So for now it works.

Just a thought, in case no one has mentioned it; most cappers will take different sized ....(don't know what they're called!) the bell shaped bit that presses the cap on to the bottle, usually 26mm for beer bottles and 29mm for cider/champagne bottles. Is it possible you are trying to seal beer bottles with a 29mm one?

I think it did get mentioned somewhere above.

Yep, I mentioned it. The OP has not yet responded with what size caps he is using, which - bizarre as it may seem - is about as logical an explanation as any of us can fathom without pics.

I agree with the person who responded further up to say that you have to press a lot harder than you might think with a hand capper. Indeed, unless I can see an indentation in the cap I usually give it a second go. But with my latest capper I don't need to do this, it is extremely good (and I can get time down to 5 or 6 seconds per cap). This is what I use Steel Beer Crown Capper thanks to recommendation from mollusc.

Only problem with it is that there are some bottles it won't do (I have found 3 so far in my collection) which have a much larger diameter neck than usual.

Only additional thought i've got is to try a different ale bottle in case the bottle shapes don't like your capper. Personally I never have a problem with Shepherd Neame bottles (and convieniently they are my favorite shop bought brews!). Perhaps get a bottle and try that?

Im using 26MM caps, the crimping bell is for 26mm caps.

It leaves a circle indentation in the top. Some of the other test bottles were fizzy others, flat. I used the same force and spun the bottle a few times,
This bench capper is slower than my hand capper.

video soon :P

so the problem looks to be the crown cup has a lump thats not meant to be there
can you get a file or dremel to fatten the inside to prevent the dinting it is doing?

I think it's a unique thing as the colonna capper which i have does leave the indentation.

It's supposed to get a better seal ironically. Crushed the cap sides and makes sure there's a seal on the inner cap.

Opened more test bottles. 3 were fizzy 1 was flat.

You've got at least an inch more gap between cup and bottle in the starting position than I have on mine, but mine's not that design so it may not be relevant.
Is the arm more or less horizontal at the moment the seal is being made?
Mine also has a magnet that holds the cap in the cup, rather than having to position it on the bottle then lower the cup onto it.

there really shouldn't be any dints in your caps
imagine
if you were to force a dint on a conventional shop bought bottle i reckon it would splay the sides of the cap making it not sealed anymore
IMHO i would get rid of whatever that lump is
you are causing more problems with a lump it too takes energy to create

It actually holds the inner crimp cup, it would be 29mm without the inner sleeve that it holds.
