While we're on the subject of doors, I'm just wondering whether to have the door latch pull to open or rotate to open. I suppose it doesn't really matter as long as it functions as it should. I'm just thinking a pull to open handle would be nice to use, seeing that opening the latch gets followed through in the same motion as opening the door. Better than having to twist your wrist. Maybe I'm thinking too much about this. What do you think?? Eric How would a pull-to-open latch work? Surely if you can open it just by pulling then wood falling against the inside of the door could as well? If you're making a door with a seal, I find it's good to have a bit of springiness in the latch (see my door pic above). That allows for variations in how compressed the rope seal around the door is, and keeps if pressed up tight. |

Hi vortex, I've got a concept design in mind that should work quite well. It will take into account the compression of the door seal and will have an internal adjustment for the amount of preload on the seal.

My door was CNC cut and folded by a local steel fabrication shop from plans I got from a Dutch guy on another forum. The CNC work was so clean and precise. Then I got a friend to weld the joints, make the hinges, weld the primary/secondary air slides and add the rim/edge for the door seal. If anyone is interested in the plans let me know. I will dig them out, upload them to my Amazon S3 site and post a link. If you could post, I, for one, would be grateful! Sorry I've taken so long to respond. The DXF file can be downloaded from hereI modified mine slightly by adding an extra 20mm to each 'wing' on the door frame to give more depth when they were folded back. There is also a clean out door and frame. |

Hi Vortex, I would call the latch in your door a rotating latch. While the door of the bakeoven (the one with the fire showing) in this link is pull to open latch. The pull to open is a hook that progressively tightens the seal on the rope.
I have rotating latches in my doors as I thought it would be easier to make them.

I got my doors back from the laser cutter last week. I thought I'd have to mortgage the house to pay for them!!! There's still a lot of work to do on them before they're finished.  I've also been playing around with the best type of machined groove for the door seal. I think 3mm deep with a 70 degree dovetail and 10mm wide at the top would make for a good seal housing. This gives about a mm crush on the seal.  Eric |

Still doing something wrong with those images. I'll try again.   |

Eric, Your pictures are working OK on the second post. You can edit your posts if something's not right. I use an 8mm wide 5mm deep grove for the 12mm / half inch stove rope. The rope gradually compacts, so I like a bit more leeway. Hi Vortex, I would call the latch in your door a rotating latch. While the door of the bakeoven (the one with the fire showing) in this link is pull to open latch. The pull to open is a hook that progressively tightens the seal on the rope. I have rotating latches in my doors as I thought it would be easier to make them.
Thanks, now I understand what you mean. The handle rotates but in the horizontal plane, so it's pulled towards you to open. |

Hi Vortex, yes I should have edited. Sorry. I'll try your 8 wide and 5 deep on my test block and see how it looks with the seal material that I've got.

Matt Walker has a brilliant option using Ceramic Fiber Panels and Aluminum hardware.
Matt, I really think it is time for you to do a build video on that application. Its a no-weld option that appears to work extremely well.

Thanks Coisinger! I did make a video that discusses the construction, but I haven't made one showing me building one because mine is already built. It's dead simple though. Here's the vid: youtu.be/K7Zu7rSpnzs |

Matt,
I've seen the vid, commented on it. Asked you to do it again and give us pointers...lol.
I appreciate your work and efforts, gives me jump off points for use of optional materials. I'm going to construct a 5"-6" batch box soon and your work with ceramic insulated board has really opened up many possible uses. Thank you.

Wow, thanks for sharing such detailed plans for what looks to be a promising design. Can't wait to see

Thanks for all this detailed advice, but I still don't understand how it's all installed and anchored to the masonry...
