<div dir="ltr">Hi David,<div><br></div><div>I recall Greg's K250 domes also had a flange because they were blown, but I also remember him saying it was absolutely essential to machine off the flange (and a little more) because the bend stresses the acrylic making it markedly weaker. He would remove the flange on a planer, and then anneal the dome. </div><div><br></div><div>When you say test, d'you mean just for test fitting the parts?</div><div><br></div><div>Best,<br>Alec</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Dec 13, 2019 at 8:18 PM David Colombo via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">Hi guys, Christmas came early today with the delivery of my blown test dome which is 30 inch OD, full hemi with flange. One for each pilot. Anyone jealous? Next step is to do a dry fit as is and a second option to be a 150 degree dome vs 180. The second option would have no flange, just a land. The resaon, is it may be a cost saving measure. Quote from Stanley Plastics in the UK $28,000 for two slush cast domes with a machine finish. As this is beyond my budget, i am looking at alternatives. I'll send photos once its on the temp hatch ring with me in it. I'm thinking though I'm liking the size of this dome!<div dir="auto"><br></div><div dir="auto"><a href="https://www.facebook.com/1145380217/posts/10221164830487440/" target="_blank">https://www.facebook.com/1145380217/posts/10221164830487440/</a><br></div><div dir="auto"><br></div></div>
