This is absolute insanity.
Some would like to impress you with the outrageous amounts that they've spent on machinery, etc. to set-up their shops. Are you impressed?
I, on the other hand, am on the other end of the cost spectrum. I pride myself in the fact that I have built a profitable business on a fraction of what is being stated in this thread.
Where in the 'Great Book of Cue Building' does it state that you have to buy everything brand new? If you are even slightly creative, you can build a lot of what you need yourself. It's not rocket surgery.
$4,000 for a spray booth, are you freakin kiddin me? I built my spray booth for maybe $200. DC, variable speed drive, multiple exhaust fans and spray gun all based on a wood lathe that I salvaged from a neighbor's garage fire.
I bought a 14" generic import bandsaw at a garage sale for $150.
Cast iron table 10" Craftsman table saw, $150 at auction.
3hp, 3/4" spindle shaper at auction, $150.
Two full size metal lathes from a buddy's machine shop, $2,500 for the pair. Sold one to another machine shop that wanted it more than I did, made half my money back and was GIVEN in the deal, another lathe that suited my needs better than the one that I sold them.
Bridgeport type 3hp milling mach. 9" x 42" table, w/ pwr. feed, $3,000 at auction.
Brand new 15" swing 2hp mill/drill with pwr. feed for cutting points for under $1,000. Yeah, I know, 'brand new' contradicts my point but at that price, I couldn't pass it up. Sure beats $3,200 to do the same thing.
One of the drawbacks to dedicated cue building machinery is, that's all they're good for. If you want to build a fixture for whatever or need to cut threads etc. you'll need to find a machine shop to do it for you. Full size metal working machines, lathes, mills, etc. are very capable of building cues and everything else that you might want to build. Dedicated cue machines will build cues but that's about all.
There are 100s of machine shops going under everyday and their machines and equipment are being auctioned off at unbelievable prices.
You might want to consider the fact that the people that are quoting you these exorbitant prices are the same people who manufacture and sell this equipment. Hmmmm? They certainly have a right to promote their own sales and I'm not trying to inhibit those sales whatsoever. You do however need to know that there are options.
At the end of the day, it's your money. Spend it as you like.
