My next job as i have posted twice before ;D is two sets of french doors with diamond shaped glazing bars running down the middle . Both sets are the same size glazing bar wise so i will make a rrrr ... a rrrrrr..... a rrrrrrr ..... a template ;D The last door i took apart had the diamond shape jointed like this  This was very weak but maybe that was because the glue was shot . I beefed the last one up with a dowel and i think for this build i am going to rely on a dowel to join the diamond to the supporting glazing bars . Be back soon with some pics of the rrrrrrr... the rrrrrrr......... the template ;D |

Well i was hoping to get away with squares but now i have drawn it out i think i am going to have some nasty angles to play with on this one .  The spec was three diamonds with equal spacings on the glazing bars all round . My brain started to hurt so i gave up for today ;D |

jason why not use biscuits to hold the diamond??? otherwise why not intersect the horizontal bar at each end so it gives more support to the diamond.? paul  |

How do you mean ? The bar is 27mm x 45mm . The angle it will be when it meets the horizontal bar will not leave a lot of room for jointing without weakening the joint in the diamond . Although i will have to scribe the horizontal bar to the diamond to make the moulding match ( i was hoping to cut it square and dowel but i dont think that will work ) It's going to be fun however i do it  |

maybe it is totally off the wall, but how about making the horizontal piece like an arrow?? basically i am kind of thinking about using the rule and scribe set, so you have the horizontal piece with a diamond cut out of its front, and the top and bottom pieces join it. that way you end up with i think more strength. does that make more sense paul |

Perfectly valid technique, there was even (before Victorian times) a dowel box tool made for the very purpose you are talking about (cue Alf?) Scrit |

Like the first pic Was there anything in the v joint such as a loose bit of tenon or a dowel? Was that a r.r.rrrr er hello Rodney? cheers Jacob |

Nothing in there , that was the joint and although very good there was a wobble in the whole construction , but it was over a hundred years old . The problem i found with trying to recreate it was it was it was weak on glue up and a hell of a lot of messing around where i think a dowel will be stronger and easier to do . Not that i dont like a challenge ( thats why i took the job on ) But i want mine to last 200 years |

how about using a flat ply strip? that and i guess cascamite paul |

It would be better to make a mortice and tenon than a flat ply strip or the like . My problem with that is i will be breaking the joint in the diamond . With dowels i can take all parts and joint them to each other without effecting any other joint ............. I think  |

New blades in the chop saw and the table saw ready to cut the diamonds now . I'm trying to work out how to gaurd or hold the cut on the table saw as my fingers are a little too close to the blade for my liking  |

make a mitre board with some lever clamps on it. certainly on the table saw, it could run in the mitre slots, and be both safe and accurate. paul |

Lever / toggle clamps wont work as the glazing bar is unstable but i groove would hold it . Good thinking  |

well you could mould a female shape in fibreglass or similar, and then put that on top or you could use the silicon that sets and have something that it rests on. paul |
