Yes correct it profits exactly $30 every 15 minutes in the cue tip business, apparently- not knocking it - just saying that a big following in the tip install business is very good money !
You are totally clueless..
Factor in costs in that figure and the $30 profit looks very, very different.
Are you even aware of how much machinery and the products we use cost? Not only that, do you think we stock 5 tips in a corner somewhere?
Every time I order from Taom, Kamui, Caiden or any other big brand, that invoice is for thousands of dollars, so most cue makers have a considerable inventory so it's convenient for you as the customer.
Since I just bought a new lathe, I have some figures fresh in my mind:
Harrison M300 £5000
Movers $1000
DRO£500
Bison chuck $2000
Then add basic lathe tooling, add $1000 there
Last time I was at my supplier for sandpaper, Clear, CA, Epoxy etc. I spent a little over $160
With your $30 profit, feel free to tally up how many tip changes I need to do to break even, remember to factor in an hourly rate for myself as well. And I haven't even mentioned electricity, rent, electrician or stuff like oils, drive belts and other running costs..
