Tyler, We didn't get a chance to get the Leclerc loom threaded, just made some modifications and then wound the warp on.
My observations so far. I really truly dislike metal heddles. We had to move and add to harnesses several hundred heddles. Texsolv is so m much easier to move and add. The metal heddles are dirty (think how dirty coins are even though they look clean). They bend out of shape etc. On this loom the harnesses are completely enclosed into the sides of the loom. Just getting the rods the heddles slide onto out of the wood sides of the harnesses was NOT easy...especially on the inside harnesses 3-6.
The lashing cord design for the warp rod and cloth beam rods was so annoying to get straightened, we replaced them with stationary texsolv cords...so much easier to deal with.
This loom is of undetermined age and my friend was not familiar with the braking system, but even when pushing on the foot pedal (HARD) I could barely get the brake to release to loosen the tension as would be needed during weaving to advance the warp.
For winding the warp onto the back beam, I was able to sit behind the loom, and wind the warp on by rolling the beam backwards by using my hands on either side of the beam and rolling it. Luckily one does not need to release the brake to go backwards.
The loom does fold (using two strong people), but the wheels are on either side of the back of the loom. So, it rolls backwards and forwards as you lift up the front of the loom, not from the side so as to fit through a doorway on the wheels.
Also, at least with 10 treadles, as my friend's loom has, it is hard to even get the space for your foot to depress the brake pedal when sitting at the front.
So far, don't know how this loom weaves, but I would not buy one. Like you, I have the David 3 and love it. I also have a Jane loom with a stand and this is the loom that is EASY to move around to weave in different spaces.
HTH...cheryl
