Yet another Glasser.
Posted: Sun Feb 02, 2014 8:40 pm
As per my welcome thread http://aussiedistiller.com.au/viewtopic.php?f=3&t=5365 , I'm slowly building a glasser.
Inspired by the great work of bt1 and Newstilla, the design I'm using is slightly different in a few ways. Hopefully mine will one day work as well as theirs.
The one I'm slowly building uses:
The smallest Primus lantern glasses, 80 x 80 (from BCF).
a 3" x 80mm high with 6 x 19mm pipes RC with the 3 x 2 reducer soldered to it.
a 3" x 200mm packed section which can be easily added or removed under the RC.
a 2" x 400mm shotgun PC with 7 x 12.7mm inner tubes
a 2" 180 bend with Triclamp at one end to remove the 180, PC...etc from the main column.
4 x 3mm plates with 1.5mm holes. 3mm to hopefully add extra stiffness (had lying around)
4 x M10 304 stainless threaded rod, nuts and washers (cheap from Stainlessstore)
EPDM channel (from Clark rubber) instead of the usual silicone gaskets.
The entire still will be soldered together with soft solder (bernzo) only.
As MacStill has pointed out many times in the past, it's great stuff to work with and is definitely strong enough. I tested the RC at water mains pressure with the outlet blocked for several hours, with no leaks.
I intend on running a 25L boiler (electric) and will build a parrot eventually.
The EPDM channel sealing the glass and other sections is a bit experimental at this stage. Here's the link to the type I'm using http://www.clarkrubber.com.au/u-section-5mm-x-5mm-08.html
If this fails, I can easily switch to silicone gaskets.
The glue I'm going to try, for gluing the channel end to end and to the glass, is Selley's Kwik Grip (solvent based). I've been looking at many different glues that might be suitable.
The reason I chose this one to try out was that it seems to stick EPDM to EPDM and EPDM to glass fairly well. It will handle up to 130 degrees when dry. It's actually polychloroprene (neoprene), which appears to perform the same as, or better than silicone for chemical resistance to ethanol and other alcohols http://mykin.com/rubber-chemical-resistance-chart-3 It should have minimal exposure to the liquids anyway.
It also appears to be basically the same as http://www.gotstock.com.au/rubber-gasket-adhesive-high-performance-946ml-1300l-3mtm-scotch-griptm.html?utm_source=myshopping&utm_medium=cpc&utm_campaign=Tools+and+Hardware&utm_term=Rubber+Gasket+Adhesive+High+Performance+946ml+1300L+3M+S , but heaps cheaper.
