Using a Louet raddle
The raddles that are built onto most Louet looms are metric. How do I lay the warp in to get the correct epi?
There are 5 slots in every inch of a Louet raddle. You just have to divide up your ends per inch evenly into those 5 slots. ie, if your epi is 20, then you put 4 ends in each section. If you have a very dense warp you can clamp a regular raddle over top of your Louet raddle. We do that with Repp weave warps that are warp faced or predominant.
