I purchased a Varpapuu Finlandia advertised as a 16 harness. The previous owner had only used it as a 4 harness and I have warped and used it as a 4 harness. It came with a pile of pieces parts (including a second warp beam. As best I can tell it doesn't fit on this loom). I'm fairly certain I have parts of more than one loom. After sorting out all the pieces and fabricating some duplicate pieces, I have harnesses, jacks and treadles for a 16 harness set up, I think. (To this point my experience has only been with jack looms.) It all fits nicely on the loom.
There is just room for 12 treadles. But there are 16 holes in the treadles. The lamms have 12 holes (not including the one to tie to the harness). It can easily accommodate 16 jacks.
Do I have a 12 harness or a 16 harness? Should the lamms and treadles have the same number of holes?
