For what reason do you want to press kief when your main goal is to winterize with etoh. Just extract with etoh.
Just do a bucket tek run and follow thelostbiologist tek TheLostBiologist Bucket and Post Processing Tek for Golden Extract
Also go Chinese for your beginning glassware. Use aliexpress, eBay and Amazon.
Deschem is a favorite Chinese glassware name.
Hope this helps.
