Jack: have you tried a bigger hammer?

Some people seem to be thinking that bending the top piece is the way this is done. The attached diagram shows why this is impossible. Even bending the top piece, the shape of the 'pin' (in blue) does not clear the corner of the tail piece (in red).

keep thinking, guys!

Jack i didnt say he gave away a clue, but the clue is in the photos.

And between the 122 replys to this thread and the 30 in Trippers "worked it out thread" i will say somewhere in those two threads their is "one small" mention of correct method (well corect for the way ive done it)

Hi Lignum,

I have attached photo's in Rippers thread. I think i have solved it but would like verification. How do i send a picture in a PM. There is no option when I tried to send you a PM.

Thanks

MIchael.

I seen the pic Michael and it looked great I sent a pm with my email.

Wonder if a moderator or someone who knows can let us know if you can send photos via PM

Go to Imageshack: -
http://load.imageshack.us/
Browse for the file on your PC and press the "Host It" button. Then you can either just send the url in your PM, or you can send the clickable thumbnail, or the entire image in a PM by pressing the "insert image" button: - , then just insert the url.
You don't have to open an account there, but it's free if you want to.

There's also photobucket, but you have to open a free account there. It's very handy for storing non-personal photos on line though.

With free hosting sites, you're not so restricted in image size and you don't have to attach your images at the bottom of your posts. You can put them anywhere you like, or hyperlink them to text if you want. Of course you could also store personal pics there in a private album if you wanted to, but I know people who have been embarrassed when their accounts have been hacked into.

Are you shore thats right though Zenwood ? .....When you flex it, it won't flex like a straight seesaw...There's a big banana like bend in it.

Meaning that 1:6 ratio or whatever, can be flexed square enough to clear that corner ......if its thin enough.

Pretty shore it work.....I think the reason it failed with me was because I hurried it......Should have cut the kerfs deeper

the diagram is correct, apricot. the combination of undercutting, plus having the centre of rotation anywhere other than at the extreme corner of the dovetail will result in an intererence between the two pieces.

All the pics of the completed joint show the clue to the true method.

yeh,....your right.....I didn't think that the bend would probably reduce the distance accross the pins etc etc.....

Go & look at Zenwood's series of pictures & ignore the one with the hammer.
Instead, use a different tool & to complete the series would require 2 photos to be put in place of the one with the hammer.

ahhhh.....shut up cliff ! your not helping mate..... I know you don't use a hammer.

has anyone ever been helped by somebody telling another theres a 'clue' somewhere ? ..... honestly.

2 photos ? ...... shore its not 3 or 1

anyway you shore you thinking the same as zenwood ? not a different method....apparently there can be more than one....oh, yeah, you probably PM'ed each other

Sorry to be the bearer of bad news Michael But its back to the drawing board for you. Great effort though, and you are "sort ov" in the right direction.

I might be just winding you up too.
