For 18 wide, gussets will do fine.
For 20 wide, you may get supports, but i beleive it will do fine even without those. So yea, supports will make it a bit stronger.
Will start on tuesday if i get the "thumbs up" from the welder,
they were just recently moving so i'm not like 110% sure that they are ready for action.
I went to workshop at its new location, talked to the welder.
At least one bar will be released within this week, very-very first V.2 prototype for Erti, so i could watch if they have any flaws or not. Defenetaly i'll take a pic of them.
If the welder has enough time, then all other bars will be done this week also, but the bars will be painted and sent NEXT WEEK anyway.
