Hi Matt, So far it looks like this gasket set is doable at a reasonable price point. I met with a gasket shop yesterday to see what they can do. We’ll need to have the lid gasket created but that’s not too bad, probably will run ~ $55 as a one-time charge. We’ll be comparing the ones Elke so kindly created and shared with the Mr. Gasket set I got from Ligenfelter. Once everything is validated as being sized correctly it looks like we’re under $50 per set, with the lid being somewhere around $20 - $25 per. Material wise they are pretty sure they have the correct cellulous gasket material but they would like to understand the air pressures the gaskets should be spec’d to. The gasket material Mr. Gasket used verses the new material they have visually look the same (without the white Mr. Gasket logo). Heat wise it should be good as it’s rated at over 250 degrees but they would like to understand the dynamics of the air pressure the gaskets need to withstand and I’m just not too sure about what to suggest. Does anyone have any ideas for this? They showed me some other standard materials that had heat ranges up to 800 degrees and with a 1500 psi rating which I suspect greatly exceeds what we need. My plan is to forward the CAD drawings Elke created to them and to drop off the lid and the full gasket set I have to validate everything before they begin cutting. This leads to the next question – how many sets to cut knowing there is the upfront charge to create the lid gasket which needs to be amortized? After we’ve determined the psi rating that is needed they will be ready to go, so what’s the suggestion on how many to begin with? |
