    Timber Framed Cider Press Design. How to strengthen the press beams.

    1830 is very modern LOL. Some of the tools I'm using to build the press are older than that.

    Timber Framed Cider Press Design. How to strengthen the press beams.

    To be frank and blunt I'm not interested in good clean design using todays methods. It is as you have said a "grand timber framing project". But one that I don't want to break. Hence the effort on the engineering. To help answer some of your questions. The two sides of the press are loaded...

    Timber Framed Cider Press Design. How to strengthen the press beams.

    Thanks for the time you have taken to respond. Dealing with last first. Yes I have accounted for the dados. The cross sectional area of the posts required to resist the tension forces in the posts is ~9000mm2 per side. The posts are 150mm x 150mm with 65mm x 150mmm dados. That leaves a cross...

    Timber Framed Cider Press Design. How to strengthen the press beams.

    The tensile strength of the posts is more than adequate for the job so vertical bolts are not need for that reason. However vertical bolts would help reduce the shear on the joints. The thing is vertical bolts are kind of hard to make look traditional or hide. According my calcs there is...

    Timber Framed Cider Press Design. How to strengthen the press beams.

    Yes I can but I'm trying to keep it looking like a traditional press. Having said that using steel to "repair" timber structures is a traditional practice.

    Timber Framed Cider Press Design. How to strengthen the press beams.

    That is the data I have on the species. The Southern Pine aggregate species you mention plus radiata and redwood I'll be using for the press. Taken from Bootle http://trove.nla.gov.au/work/8697176 Based on that data the Slash is superior to the long leaf. And the radiata superior to the...

    As I understand it P. radiata isn't grown commercially in the US

    Timber Framed Cider Press Design. How to strengthen the press beams.

    That is awesome help. So what is the species for southern pine? Monterey pine is one of the most widely cultivated plantation species but getting information on it for large section timber framing applications is......challenging.

    Timber Framed Cider Press Design. How to strengthen the press beams.

    Hi Peoples, Now I'm finally getting around to a project that has been on my to do list for ages. We have been making cider from wild apples for about the last 6 years. As much as 500L per year. Processing the apples is a huge job so eventually I made a scratter to speed the milling process...

    Joint design of a post and beam associated with a knee brace.

    I've got a bunch of the publications from the TFG but the most relevant two are: http://www.tfguild.org/store/timber-frame-joinery-design-workbook http://www.tfguild.org/store/timber-frame-joinery-design-volume-2 "It wouldn't be at the mid-point or anywhere else in the beam. You'd no longer...

    Joint design of a post and beam associated with a knee brace.

    Bearing in mind I'm still self teaching (as distinct from taught) structural engineer.... Timber framing manuals produced by the Timber Framing Guild recommend to ignore the effect of braces under tension. So I don't think you can assume the point of inflection is centered in the beam. Rather...

    Joint design of a post and beam associated with a knee brace.

    I've had some ideas but I'd appreciate more input.

    Joint design of a post and beam associated with a knee brace.

    @jdgengineer I'm surprised that you would say that the limiting capacity is that between the knee brace and the post. I guess it would depend on the joint. If it were a beam tennoned into a post then that could makes sense. I still would have thought that the tenon or the peg/s would have...

    Joint design of a post and beam associated with a knee brace.

    Knees braces are used to prevent a post and beam frame from wracking under lateral loads. Everyone knows that. But just adding knee braces where ever isn't a solution. The size of the knee brace (as in its length) makes a big difference. The longer the knee brace the more it protrudes into...

    Manifold outlet spacing

    Here is a case that is neat in terms of pipe layout but seems like a bad idea. M=manifolds 225mm I=inlet 100mm O=outlet 65mm I I O O I O O O I O MMMMMMMMMMM O O O O...
