What makes a good gasket ?

[stubbydrainer]

I'm just about to cut a 260 mm hole in the top of a keg (for cleaning purposes), and make a slightly conical cover for it 310mm dia with a 90 mm riser with a 4" flange on top of that, to mount the still on
The lid will overlap 25mm around its circumference, and reattached using 6 or 8 x 1/4" stainless bolts welded on place from the inside with wing nuts and washers on the outside.
But what makes a good gasket, do the "new type cork gasket" cut the mustard ? ( vulcanised cork , I think its called :? )
about 2 mm is what I was thinking
What does the brains trust reckon ??

Mac
how long would that last ? 3-4 runs or would you have to do it every run ?
I was sorta thinking about it , and thought "surely, there would be another way to seal it up without that fucking messy shit every where :angry-banghead:

[MacStill]

Personally I wont use the shit & what I'm doing is an 8" ferrule on the top of my new boiler, then a disc to fit it with a 4" ferrule glued to that..... expensive yes, but I'll never need to do it again and I can use off the shelf gaskets :mrgreen:

The's a good tutorial on Artisan somewhere on making gaskets with silicon.

Personally i'd cut one out of insertion rubber.

[stubbydrainer]

thanks 5Star
I'll go have a look
I would have thought insertion rubber would be affected !

Found somewhere, waiting for reply

or maybe a trip to a kitchen shop :? , for a baking mat !! ( apparently :o ) I'll have to go alone, I never get out of them sorta places without a new something or other that costs big bucks :crying-yellow: :violin: when I get dragged in by the :angelic-little:

Cheap as chips Stubb"s Silicone Baking mats $5.00 each


:mrgreen: Hoppy :mrgreen:

[maheel]

what about laser cut teflon sheet for big ones? mob near me cuts em but i have priced $$ them

i know you just send in a CAD type file and bzzzztt zaaaapppoooww it's done :mrgreen:

[stubbydrainer]

the teflon sheet thing is interesting Maheel, wonder what it is like ?, let me know when ya get a ballpark price

I bought a silicon baking today, I have some reserves with it being it is only thin ! but should be OK if it is tripled up, and it isn't big enough to got a few 300mm rings outta, but I got it with the elements in mind....square bolt pattern type.... so there's plenty for that !
I ended up getting 1 x 3600w and 1 x 2400w sickle type elements, incoloy 825,
SBB's young fulla is a sparky so together we went and got em, off the shelf at his wholesalers at a good discount , had to order the screw in type, and they were heaps dearer as well,
Now can start ripping into the 18g keg after I get a few little jobs outta the way :dance:

Hey Stubs,I got some silicon sheet from that jehbco mob a couple of months ago,very reasonably priced and good service.Talked to old mate on da phone and they have quite a wide range of thicknesses and types of silicon sheeting.He even sent me 4 30x30cm samples...can't complain about that :handgestures-thumbupleft:

[stubbydrainer]

Good to know BD
I sent'em an e-mail and haven't heard anything back yet :sad:

[Cane Toad]

Ring the mobile number mate,fuck the email,I prefer talking to someone,at least you can explain things to em.got old mates card inside will dig it out and post it for you shortly

[stubbydrainer]

thanks BD :handgestures-thumbupleft:

[stubbydrainer]

will ring tomorrow thanks
What sort of samples ya get ? any about 3 mm thick ? :laughing-rolling:

[Cane Toad]

Got 2 sheets 2mm thick,one solid silicon and one like a foam,but sealed on both sides and the other 2 sheets were 4mm thick and the same densities as the 2mm.
I found the low density stuff the duck nutz for the sight glasses for the 4"er I got off of Mac.you didn't have to use anywhere near as much pressure to get em to seal

[stubbydrainer]

yeah, I reckon the pressure to get a seal on the silicon bake mat I gat today would be fuck all, which is good coz the elements mount bolts can't be tensioned more than 15 Nm ( yet to convert to ft/lbs or in/lbs ) which would be a bee's dick off fuck all

[Cane Toad]

Well he's da man to talk to,real helpful.....just like me :laughing-rolling: :laughing-rolling: :laughing-rolling:
