Hello all,New here.Just wanted to see what yall are doing as far as sealing,ironing your mylar bags of what ever your putting in them.....I made up a nifty little device that is essentially a 1/2" steel tube welded onto a pc. of 1 1/2" muffler tubing. The 1/2" tube is about 8'' and the 1 1/2" tube....about 4" long....it goes on the hose of my small wet/dry vac. I lay my mostly full 4.5 mil-5.5 mil bags down on the table at a slight angle,to avoid spillage.....insert the 1/2" tube into a corner of the bag.....get out the OL's iron and iron a 1"wide seam right up to the tube and along side the tube.....hold the tube in place so it doesnt fall out....and hit the go button on the vac. It draws down damn near hard as a rock!!!....................at this time,I switch hands,grab the iron and work it on the space where the tube is.....SLOWLY pushing out the tube with the iron and iron it closed giving you a nice seal!! It may take some practice but it's just about fool proof!!! You can do the same thing with your 2-6 gallon buckets....same method but it requires a bit of co-ordination!! Of course it's good to throw in a 500 cc 02 drier in your bags and several of them in your buckets!!
