I build wheels for a living, from past experience I have shared plenty of knowledge with people. A couple of them decided to start their own wheelbuilding brands as a hobby subsidised by their day jobs, they also got in touch with a few of the brands that I regularly built for and offered to supply them at a cheaper rate than me. Thankfully I had loyal clients that let me know and continued to work with me knowing that this was my only income.
Due to this, I tend not to discuss my process with anyone.
Some of the reason that wheelbuilders charge what they do is overheads, cost of tools and the upkeep of them (recalibration of tensiometers etc) and the price of public liability insurance. Also some wheels only get built after a lengthy discussion with the client, 10-20 emails maybe. This is all time that needs to be charged for. Usually rim tapes/tubeless tape is included in build labour too. There is also the time taken to measure all parts and calculate spoke lengths. We cut and thread spokes in-house to 0.5mm increments for more precision, off the shelf spokes are usually available in 2mm increments.
I encourage people to do as much stuff themselves as they can and be self sufficient, you don’t need the best/most expensive tools out there to do a great job.
But I feel that lots of people think that we overcharge without considering the aspects I’ve previously mentioned.
Sorry! Haha. Rant over!
Why not calibrate your own tools by building a tensionmeter calibration jig and using precision ground measures to check DTI's, micrometers and verniers?. Save yourself time and money and the need to double up on tools you send out for cal.
Insurance shouldn't be hanging on you having to use a third party service as if you do it right an engineer paid for by an insurance company will find your tooling to be well within acceptable limits, for wheelbuilding. This isn't nano tech we are dealing with here.
Also; why on earth are you playing email tennis?
If somebody asks you to build 12 spoke wheels and in the next email you find out they are 20 stone and 'send it' off piste then you just say no and tell them what you think they should have. If they dont accept you have done you a favour and you move on to the next person.
Same applies to people who want to argue about heads in/out, crosses and d/s or nds radial. You should know what works and be confident telling someone what you think. If they dont accept then move on.
It is always worth keeping an open mind to what someone says, as they might actually be right, but if you have been doing this for a long time you know what works.
Nothing about building a bicycle wheel should take 10-20 emails/phonecalls. That is absolute madness and you have just told everyone that a client might have to pay for all the time you spend faffing about with other clients.
I would take a guess, based on my experience, that a good portion of the people who want to play text tennis don't end up buying any product. They are timewasters born to suck the last drop of desire out of the self employed and as soon as they are identified contact should cease.
