    Thanks Pere. I'm excited about it to :0) I'm making a few final adjustments to the overall design to make the camera easier to setup and also to simplify the manufacturing process. Once I'm happy with those, I'll build another one and get it out in the field to test it thoroughly.

    Let point a way I use with 3d printing (instead laser, that also I use), for the case it can be useful to manufacture some rigid parts that you may need to be very more rigid.

    Rather than printing the 3D part I print a PE mold of the part, and I fill it with a technical resin mixed with cut fiberglass (1/4" or 1/2" length), it works like reinforced concrete. Also sometimes I place a metallic (alluminium, titanium) part inside the mold, usualy a (perhaps angled) plating with holes, or little pipe. I also add black dye to make it light tight.

    This delivers very rigid parts, perhaps it can be useful to make a 5x7 or 8x10, where rigidity is more critical. The Polyethylene 3D printed mold can be reused some 50 times, just spraying the mold with Silicone Mold Release Spray before pousing the resin+Catalyst.


    Also sometimes I use Fiberglass Reinforced Plastic (FRP). It can be cut it with water jet.


    Regards

    Thanks for advice Pere, that's very useful information. With my 5x4, I've redesigned the hinge mechanism since building the first version to remove the need for the 3D printed hinge due to the added cost and complexity. I now have the hinge mechanism built around laser cut acrylic parts instead which, whilst being faster and simpler to produce, should also increase stability (along with the vertical supports either side of the rear standard) over the printed hinge.

    Cheers

    It's been a while since I updated my progress but I ran a dry assembly of my Chroma to check the alignment/fit;

    I've also finalised my bellows design/assembly so all three layers (internal blackout, card ribs, external colour) are laser cut then laminated so I can now cut/assemble a set of bellows in around 20 minutes which is a massive time saving for the overall assembly.

    I've also changed the focusing mechanism to move away from a traditional rack/pinion layout and am now using a rubber friction assembly which gives a completely step-less adjustment;

    I'm planning on launching my camera through a Kickstarter campaign in August.

    Here is a new one I just finished. After completing my 520/15 Zeiss Ikonta with a fixed 47mm Super Angulon a couple years back, I almost immediately started building a companion camera with a less extreme 65mm in a focus mount. As always I enjoyed the process and the problem solving, especially glad I sent it to a leather guy and had the camera recovered after stripping the old paint and leather. Enjoy!

    Agreed - just not medium format cameras!

    Aw, Steve. Can we lighten up a bit? Good ideas come from diverse projects. For example, this is one built from a nominal MF Veriwide 6x9 camera with 47mm f/5.6 S-A (actual format 56mm x 80mm) with a snap-on 4x5 back. Super rare, or at least strange. It also accepts rollfilm backs up to 6x12cm.
