Finally going to Wickes/B&Q later today (1:30am, gasp!) to buy some MDF. The initial plan was to bore through MDF to a brace of timber, then essentially bolt the MDF to the timber. However, considering the amount of "joining" I would need to do, this may be quite a pain. I do understand screwing MDF-to-MDF isn't a very strong hold, what if I just screw THROUGH the MDF to the timber behind it? Kinda like substituting a screw for a bolt. Thoughts?
