[PSUBS-MAILIST] Got vacuum !

Brian,The land will be your guide, you don't need a flat glass or anything like it.  Your hatch will be matched to your land regardless of the flatness of the land.  Just always test fit the hatch in the mounted position, as if it were in the hinges.  It really is easy!Remember, no one likes a coward.Hank

 Hmm, interesting.  The gap is on the hatch part. the land on the sub is good.  I'm pretty sure that's the case anyway. Brian

Brian,Been there done that,  it is quite easy to fix.  Emile is correct, just take your grinder with a flexible disk and buff the high area down.  Just place the hatch on the land and use feeler gauges to find the gaps and mark them with your chalk.  The fixable disk is very slow at removing material, so you have plenty of control.  I had the same problem with my land on my escape pod and I fixed it easily.  I got it to within .004 and it went to 638 feet.  Don't panic about a little gap.  Just buff then check then buff then check...... oh ya, you can use super coarse disks.Hank

 Got to straighten this hatch thing out.   Emile suggested that it would be possible to grind/ sand down to get flat, sounds a bit harsh, not sure how I would go about doing that.   I need to get a flat surface, like a granite surface plate or a piece of glass so I can determine flatness.  I knew I shouldn't have welded those hinge flanges on after welding, but I had assurances that it wouldn't deform anything !  Last time I take advice like that !   That side pulled up just slightly so I would have to turn or grind down about 2/3 rds of the hatch by about 75 thousandths to make everything level. Brian

Congrats, Vacuum afterbuild or rebuild is a special moment. Carefull grinding andsanding may fix that instead of the lathe. Regards, Emile Van:Personal_Submersibles [mailto:personal_submersibles-bounces at psubs.org] Namens Brian Cox via Personal_Submersibles

Onderwerp: [PSUBS-MAILIST] Gotvacuum ! HiAll,          My subs sitting with26" of Hg over at my shop !!     Did have a bitof a problem however,  I had to clamp the hatch down because I have aslight warp, probably from a couple of welds done after machining, should beable to remedy that with another trip to the big lathe. Brian Cox_______________________________________________Personal_Submersibles mailing listPersonal_Submersibles at psubs.orghttp://www.psubs.org/mailman/listinfo.cgi/personal_submersibles
