I've seen the page in question on the Warmoth site. The only reference to depth is in regard to gibson humbuckers, and doesn't indicate if the depth is dependent on a carved or flat top. As that is not in reference to what I am building and the Kinmans are not a typical depth, I didn't see the harm in looking for more specific experience while I wait for parts.
Side note: it's not super encouraging for inexperienced builders if they're going to get grief for asking questions. Since my actual question was if anyone here has built this combination and you jumped over it to be smart, I'm going to guess that you have not and cannot actually help me.
Apologies if my reply sounded smart. It wasn't meant to be. I meant it to be
brief. I had other things to do the day I posted that & wanted to make sure I got that reply in, then I was off...
As to the part of your original post calling for experienced builders in this combo, I would respectfully suggest you may wait a while for anyone to chime in, who may have had such experience.
Kinman pickups are expensive and almost boutique in manufacture number, and this is coming from me - an Australian - who would want one of my own to 'win' on the world stage! Couple that with the less popular Jazzmaster body, and your guess is as good as mine, as to how many folks would have had any experience with the combo of pickup & body shape you are doing as a project.
I did do a Jazzmaster project guitar a few years back. I encountered problems that were primarily my own engineering & am always interested when a new Thread about Jazzmasters pops up. If I can stop someone from making the same costly errors I made, then I will jump in a reply.
I don't know why you brought in the issue of carved top? Your Thread title strongly suggests a flat top guitar is the project subject ("Jazzmaster"). If so, the issue of curvature of the body is totally irrelevant on this project.
As regards to Warmoth's page, I see it does mention a depth of 3/4" on the P90 routing section. It's shown in the routing drawing for the P90. Is that not the information you were seeking?
On Kinman's page (page 2 of 7), they recommend a total depth from bottom of thickest string, to bottom of cavity, of 34mm or 1 1/4". Kinman's info also details the depths of numerous guitar bodies with the Gibson SG being the thinnest. A Jazzmaster body would be closer to the depth of a Strat or Tele than a Gibson SG.
My quick guess is, therefore, that whatever bridge you set on the body will help determine the overall total depth (as per Kinman's page) & the type of action you will achieve when you bolt the neck in place.
Warmoth will give you very close to 3/4" cavity depth (bar a coat of paint) & above that, to reach the goal total depth of 1 1/4" (34mm), will be up to the bridge saddle height. My maths tell me you need another 1/2" from the top of the body after Warmoth rout the P90 cavity? Agree?
