I tried to build stack 2D system with DLA projectors by DIY. Ive ever also experienced DIY tuning of CRT projectors, SONY VPH-D50QJ and VPH-G70QJ. They need much works and furthermore difficult. Tough the tuning flexibility of fixed pixel is less than that of CRT, difficulty of tuning DLA stack is lower onerall, comparing CRTs.
In this article, wooden DIY mount and workaround for image distortion is described. The accuracy of the physical placement with two projectors is the most important matter. Moreover, it is a secret to the success to use the part of the lens with a little distortion.

3. Dual projectors, JVC DLA-HD750 hanging upside down.
4. The secret of tuning with two fixed pixel purojectors.
