description In this joint contribution we announce the formation of the OPEN LATtice initiative to study Stabilised Wilson Fermions (SWF). They are a new avenue for QCD calculations with Wilson-type fermions and we report results on our continued study of this framework: Tuning the clover improvement coefficient, and extending the reach of lattice spacings to $a=$0.12 fm. We fix the flavor symmetric points $m_\pi=m_K=$412 MeV at $a=$0.055, 0.064, 0.077, 0.094, 0.12 fm and define the trajectories to the physical point by fixing the trace of the quark mass matrix. Currently our pion mass range extends down to $m_\pi\sim$200 MeV. We outline our tuning goals and strategy as well as our future planned ensembles. First scaling studies are performed on $f_\pi$ and $m_\pi$. Additionally results of a preliminary continuum extrapolation of $m_N$ at the flavor symmetric point are presented. Going further a first determination of the light and strange hadron spectrum chiral dependence is shown, which serves to check the quality of the action for precision measurements. We also investigate other quantities such as flowed gauge observables to study how the continuum limit is approached. Taken together we observe the SWF enable us to perform stable lattice simulations across a large range of parameters in mass, volume and lattice spacing. Pooling resources our new initiative has made our reported progress possible and through it we will share generated gauge ensembles under an open science philosophy.
