Ok guys and girls after a year of research on here I'm ready to build the Jgro design it's small and simple and can fit on my work shop with no problem. I started cutting some parts today I got the cutting table done and now I'm working on the adjustment block large. Has any of yall had any problem cutting the hole on the adjustment block all most all the way through and the MDF comes appart on the bottom I've went through 7 and only got 3 so far. I'll have swap to delrin soon.
