Yeah, it can be made...although, I'd rather spare the time & footwork to find someone to do the proper cutting & welding for me. Yeah it's expensive... It's also stainless, being shipped from japan & w/ both of those things in mind & the fact that I really don't want to screw around w/ finding someone trustworthy to do the work, price is somewhat on point compared to domestic availability.
So, IMO it will cost me just as much to buy a domestic system to hack up, plus cocktail shakers, plus labor & materials & dealing w/ finding someone who's not a complete jerkface, to do a proper job to my standards.
I have an upswept system on order for half this price, but it's backordered...& the company I ordered from cant even give a guesstimate of when it will be available. It's all very irritating.
