If the scratch was near the center, it can be wet sanded with a pneumatic orbital sander feathering the surface out. Basically spread the sanded area over the whole surface. Use finer and finer wet sand grits till you reach 1500 then hand rub it clear.

I ran into the same thing when laying out the side viewports for my sub- the ports needed to be comfortable to look out of and still give a good view downward. Captain Kittredge made the ports for me and made them extra heavy so they could be welded in "angled down" without losing too much strength. The view turned out to be pretty good.</div><div class="yiv3494302162qtdSeparateBR" id="yiv3494302162yui_3_16_0_ym19_1_1491787296395_2843" dir="ltr"><br clear="none"></div><div class="yiv3494302162qtdSeparateBR" id="yiv3494302162yui_3_16_0_ym19_1_1491787296395_2851" dir="ltr">Just curious- how was the comfort/ view in your previous spherical sub compared to the new sub?</div><div class="yiv3494302162qtdSeparateBR" id="yiv3494302162yui_3_16_0_ym19_1_1491787296395_2858" dir="ltr"><br clear="none"></div><div class="yiv3494302162qtdSeparateBR" id="yiv3494302162yui_3_16_0_ym19_1_1491787296395_2859" dir="ltr">Greg C<br clear="none"><br clear="none"></div><div class="yiv3494302162yahoo_quoted" id="yiv3494302162yui_3_16_0_ym19_1_1491787296395_2795" style="display: block;"> <div id="yiv3494302162yui_3_16_0_ym19_1_1491787296395_2794" style="font-family: verdana, helvetica, sans-serif; font-size: 13px;"> <div id="yiv3494302162yui_3_16_0_ym19_1_1491787296395_2793" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div class="yiv3494302162yqt5575531946" id="yiv3494302162yqt45325"><div id="yiv3494302162yui_3_16_0_ym19_1_1491787296395_2792" dir="ltr"> <font id="yiv3494302162yui_3_16_0_ym19_1_1491787296395_2797" face="Arial" size="2"> </font><hr size="1" id="yiv3494302162yui_3_16_0_ym19_1_1491787296395_2796"> <b><span style="font-weight: bold;">From:</span></b> hank pronk via Personal_Submersibles <personal_submersibles@psubs.org><br clear="none"> <b><span style="font-weight: bold;">To:</span></b> Personal Submersibles General Discussion <personal_submersibles@psubs.org> <br clear="none"> <b><span style="font-weight: bold;">Sent:</span></b> Sunday, April 9, 2017 11:41 AM<br clear="none"> <b><span style="font-weight: bold;">Subject:</span></b> [PSUBS-MAILIST] Elementary 3000 redesign<br clear="none"> </div> <div class="yiv3494302162y_msg_container" id="yiv3494302162yui_3_16_0_ym19_1_1491787296395_2876"><br clear="none"><div id="yiv3494302162"><div><div style="color: rgb(0, 0, 0); font-family: Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 13px; background-color: rgb(255, 255, 255);"><div id="yiv3494302162yui_3_16_0_ym19_1_1491750976757_2562">Hi All,</div><div id="yiv3494302162yui_3_16_0_ym19_1_1491750976757_2562" dir="ltr">I made a BooBoo when I designed Elementary 3000. I did not spend enough time mocking up the port position for comfort. With the current port location in relation to the hatch, it is uncomfortable. If I raise the port 10 inches by rotating the sphere it is comfortable. I can lean forward easily and look out the port in this position. This means my hatch would be off level at the surface. Does this matter? it is better for staying open I guess. The back of the land will be 3.5 inches lower than the front. </div><div id="yiv3494302162yui_3_16_0_ym19_1_1491750976757_2562" dir="ltr">I am building a new body for the sphere to sit in-it will look more like a Square plastic ROV now than a submarine.
