Many years ago in Milwaukee I used a product called Duron—tempered all the way through hardboard. Not having much luck finding that now in Northern Vermont, though I was happy with it. Last time I used 1/8” tempered Masonite because that’s what I could afford…and it lasted about as you’d expect in higher traffic areas. I’m considering ¼” MDF because it’s cheaper than ¼” Masonite and may well be more stable particularly in the summer when the stage gets the hardest use. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Any serious downsides or red flags to the MDF? There will be custom cutting around the edges of the stage and milling for screws, but I will have very good ventilation and masks will be worn.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks in advance. <o:p></o:p></p><p class=MsoNormal>John<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b><span style='font-size:16.0pt;font-family:"Bradley Hand ITC"'>John Paul Devlin, MA, MFA<o:p></o:p></span></b></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Bradley Hand ITC"'>Associate Professor of Fine Arts, Theatre<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Bradley Hand ITC"'>Resident Designer and Technical Director<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Bradley Hand ITC"'>Saint Michael’s College<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Bradley Hand ITC"'>802-654-2509<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Bradley Hand ITC"'><a href="mailto:jdevlin@smcvt.edu">jdevlin@smcvt.edu</a><o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
