I have a David 3 and a Baby Wolf, I want to have a loom that is set up for sectional, but I don't want to do it to either of these looms. The baby wolf because Schacht mentions it can make the folding not as compact, the David because I want the option to have shorter warps.

Has anyone thought about doing a sectional beam on the David and then adding in the second warp beam for non-sectional? Would this even work?

I have the sectional beam on my David 3 and love it. you could, however, just attach the additional metal rod to the one that comes with the sectional kit and warp it in a traditional manner (back to front, front to back). When you wind it on, you wouldn't have to add any paper or sticks as you'd still have the metal dividers to keep things tidy.

So you could still warp back to front and not have to tie the warp into 1-2" sections and attach it to the strings I've seen used to attach warp to a sectional? I just looked up the sectional kits and the one that made sense was the one for the Delta. So just make warp chains in the size of the gap, use a tensioning device at the front and beam on as sectional/standard hybrid?

Do you find the sectional is better in normal use than using the standard beam?

The sectional kit comes with another metal warp rod that attaches to the new beam with short little texsolv cords. You could attach your existing rod to that one with additional lengths of texsolv. Be sure to give yourself enough length on the new cords, and that the metal rod falls in-between the metal hoops on the sectional beam when it's wound on. At that point you could wind on a warp in the traditional way (back to front or front to back) and not use any additional warp packing material as the threads will wind on in between the metal hoops

I have an AVL Warping Wheel . This measures and tensions each individual 1" section which I then wind onto the sectional beam a section at a time. So easy to warp by myself, regardless of the length/width of the warp....so....I don't use the method I've outlined above. I do have 2 other looms. A Jane table loom and a Woolhouse Tools Carolyn table loom and warp back to front on those similarly to how JST shows.
