I am about to place an order for 3/16" plate work. If anyone needs anything, send me a CAD file to sales@aftershockmotorsports.com and I will give you a quote. This is going out soon though. 5/16" is next then 1/8". I get charged a setup fee per material so I group like thickness pieces together.
There will be another 3/16 order in there somewhere too. There are some prototype parts in this one that I will either need to tweak and prototype again or get a batch run.
