Worse yet, let me see someone else get all of those component leads lined up and in the holes if they are all potted together. And then be able to do a alignment to it after all this is done.

You would be amazed at how on frequency it is just buy putting those in cans and grounding the cans and getting rid of the heat. It is obvious DJ that you don't want this kit to become available. Well, that just motivates me more. Then, when people use it and it actually works your shit will all go blow it out the window.
Shakes...
When are you going to tell people that you are asking for money on gofundme?
https://www.gofundme.com/entrepreneur-veteran
And you are asking for $5400 to buy some hot glue and epoxy to pot a few cans?
Are you going to tell people funding this that these are for CB radio widgets?
Come on Shakes. Come on.
You don't have the designs. You are here on WWDX trying to get help designing them.

Oh, I'm sorry, I didn't know GoFundMe was a crime. Obviously you have a lot of jealousies and animosities DJ. Don't worry, this time I won't cut into your CB repair Beer Money. And since you want to talk about imperfections, how about that tube amplifier you sold Paul. You know, the one he brought back 3 times and you couldn't make it work right straight from the beginning. He had to sell it. Yeah, what you say carries no weight and don't worry, I won't make fun of your boyfriend down south this time that got the wild hair up in your ass in the first place.
Let me explain to you how this works Shakes.
You need to create a customer.
They have to need or want the product/service.
That means the product or service needs to at least pass the basic smell test as to not look or smell like snake oil.
Your "products" that you have designed are not mentioned on the page.
Your products include..
- A potted block of parts to fix a problem in a radio that will not be fixed by potting them in a blob in the first place.
- A mod to the GNF that you have already admitted to not having even started to do, and the GNF is nothing more than an active filter. So what is it? a kit with a couple resistors and caps to alter the frequency response? That's a "product"?
- Some resistors to "volt" the meanwell power supply in a 2547.
And your only potential "real" product is a plug and play channel mod.
Something that nobody has done but there is not going to be some mad rush to buy and certainly won't absorb $5400 in R&D or even initial production costs to produce.
In case you haven't noticed but a stack of production quality plain green soldermask PCBs cost tens of dollars. If that.
You do not mention what these "products" are. Just that they are for "the industry"
What industry is that? Is it a meaningful industry?
You have ZERO marketing strategy because all you have is a poll on a forum where 30 people said, yeah its a good idea. (and I agreed too)
Your target market is literally tens of people.
There is no "demand" for your product. It's "tens" of people.
Two weeks later you post a rant on your own gofundme because people won't give you money.
How professional Shakes.
Way to encourage someone to invest!
What we have here is someone (you) that can not not grasp the basic concept of how to stabilise a crystal oscillator. I handed you the solution to a product on a silver platter. As did some others.
It is not illegal to create a gofundme.
But your gofundme is DISHONEST.
You make claims that you have these things, you do not even describe what they are or their function and then proceed to discuss your hardship living on social security.
most of the gofundme is about your hardship, not your products.
What did you expect?
The money isn't for a product. That much is obvious.

I do not rely on DJ to verify my actions. I will do what I am going to do and if I fail, then I fail. But until I fail you can stick your negativity where your RF meter doesn't work.
As I said, I am going to have it produced. Nobody said you had to try it. Nobody said you had to use it and I certainly don't need or care about your approval.

Well, I see this kinda took a turn in a different direction...
As I see this, there are two types of events - and maybe even more - in why the VCO/XCO drift like they do.
Obviously Temperature is one of them,
But another is a leakage, or even proximity effect caused by leakage, amongst a series of parts arranged in a fashion that tends to amplify the effect than to tame it.
For some to look at this the way I see it, perhaps it is more of ISOLATION versus proximity.
As said earlier - radios use to use foil shields both above and below the section to keep stray reactive events - be it Temperature, Humidity, Capacitance and even Inductive reactive effects from influencing the area to provide stability in the midst of all the list above and then some - including voltage and ground current ripple effects on the power supply and the ground references.
So a lot can be said about temperature - but then controlling the environment as much as possible - either by shielding or by sealing - can play an important role in not just stability but the effects of the external affecting the internal. This (the form of protection or shielding) can be reduce the environmental influences to provide a level of accuracy to the oscillator, as well as provide a form of compensation to the external effects to dampen them - which when both are applied - can provide a level of offset to the inherited drift.
It may not be a perfect solution - but it can provide more stability than to simply provide an oven with a temperature that can generate another problem of Mean Time Between Failures MTBF caused by stress from heating at point sources to localize their thermal effects to within small regions.
In the oven appraoch - we may have fixed a crystal to a set temperature - but have done little to provide the crystal with properly set reactive, resistive or voltage values that the cooler, humid or electromechanical interference of vibration on mobile environments - can generate - they are external events affecting the internal reference you're trying to generate.

@Handy Andy
I have done both.
The oven works.
Shielding does nothing. It's not an EMC issue.
Stuffing parts into epoxy is not an answer here.
Happy to share my data with you if you want to see it.

Those are the words I was looking for Andy. You just nailed it for me. Thank you. It deserves being read twice. Maybe even three times.
I'm looking at a lot of different approaches - not just oven. One problem I see very often in the shop is due to vibration and shock - people aren't exactly kind to their equipment - accidents do happen.
I was working on a radio here just earlier that had those side mount vertical boards - an older Cobra 18 RV so it was a piece of work - even the traces lifted from the main PCB - just from bouncing around - so the issue of stability on a electromechanical principle of the crystal itself seems to be a moot point because even Silver Solder is inherently brittle and can tear traces from the board.
Seems that Pb had one set of issues (Toxicity) and now Silver with it's own set (Brittle and Melting point)- well, the days of radio may be numbered because they are so disposable nowadays...
