I don't know Jay ,
But got to stick up for her a bit here, can't stick up for excuses though but I know a little bit about anodising and can appreciate when anodising a 30 year old part that is cr#p grade alloy. ( old school bike parts are not a nice grade)
It will only anodise as good as the surface and will show up tiniest of scratches, I had some side panels done for a motorbike and they were scratched, bare alloy but scratched and I had to spent hours on them to get rid of the scratches, I got down to 1500 paper and soap.
I even had to rub it down the same direction or it would have looked terrible anodised, even then it was touch and go whether they would look good and not show up imperfections that I could not see
CNC machined alloy comes out lovely :daumenhoch: when anodised, forged /cast alloy is a different matter.
My anodiser done a set of Dura Ace cranks for me, he tests all the alloy before doing it, he commented on how cr#p the alloy grade was on bicycle parts and in the end I had to have them done in natural silver, if you take 2 pieces of alloy and they were made in different years or the grades are slightly different they come out 2 different shades and their is nothing you can do about it.
So I sympathize with some of the stuff that she has to work with, my first set of Dura Ace looked really good but had corrosion under the original anodise but you couldn't see this until it was stripped and these were NOS, once stripped the new anodise highlighted the pitting that was not visible.(probably started the oxidising process just before the original factory anodise back in 1980)
Sometimes you can't tell how good the item is until it's been stripped back and 30 years of a bike part that's been in a shed doesn't show up until it's been redone, you can only work with the best that you have and can't work miracles.
The wheel rims pictured above are a good example of this , some corrosion is too deep to polish out a can look worse than when you started.

yeah we do sometimes forget these parts are 30 years old and not brand new.
McQUEEN:
Jay has completed some peregrine rims and seat post clamps for me, all used but not corroded, which I thought she did a full on / top job for. She also did some nos, never out of the packet, silver tech 3's to blue which were inconsistent in colour. She also promised that the steel pivot pins wouldn't colour but they did (easily rectified though with a dab of silver paint). None of it is easy, especially when its a 'sideline' to your main work and comes second.

I here ya guys, i hope it gets sorted to.
I dont think ive asked to much or hassled Jay at all, i think ive been quite good about the whole thing.
I totally understand about how old and mashed some of our parts are but if you coming onto a old school bmx site offering your services you must know what your getting yourself into.
SBD has done all of my powder coating and the few times i have given him a frame/forks that have problems he has always spoken to me BEFORE going any further with the work and i must say every time he has suggest which way to got the fix comes out spot on.
Sawsall has done a couple of badley buckled and flatted rims for me which i thought were toast he has come thru and sorted them.
2 things that strike me it seems Jay has alot going on with work, animals and home life also SBD, Del, Sawsall etc are all BMX people so they really really care about other peoples parts and understand that these are most of the time not easy parts to source etc.
I dunno what else i can say apart from it has taken me over a week of sleepless nights woundering whether to post this or not as i dont like to bad mouth people.
