I have tried adding more solder to the joint and as expected that did not work so well or at all for that matter.
There is a possibility that we are overheating the material during the soldering process.
I will explore that a little further.
I will be running a couple of test next week to try...
Yes the joint is dry.
There is never any liquid in them until it is at much lower temps.
We are working on the system at room temps with the system discharged so no liquid is present.
I don't believe any of the normal soldering problems apply to this situation.
Something is happening that is...
First a little background.
We are soldering some copper tubes on a thermo-siphon used in an ultra low temp freezer.
The solder we are using is a lead free mix.
It consists of 96% tin and 4% silver non-flux core.
We then use Rubyfluid liquid flux.
In case anyone thinks it is important we are...
Well I machined my parts so it is what it is now.
we stuck with the +0.0000 -0.0003.
For references sake I believe this is real close to a class M7 fit which is not considered an interference fit but rather a press fit.
I have not actually put the bearings in yet because there is still some...
Sorry once again I did not give enough info.
It is a two row ball bearing.

I think the table suggest +0.0000 -0.0003 for the 3.1495 bore which will make it a M7 tight fit.
I have gone through the engineering materials from Timken and am unable to fine any reference to my bearing number.
So I just picked the fit that most closely matches my bearing type and size with a fixed housing and a rotating shaft.
The info I am going with is on page 128...
I have searched all over for this type of info and am unable to find it.
The part number according to Timken's site is 513180.
I am unable to find that part number in any of their PDF files in relation to engineering references and tolerances.
The bearing is being used in an automotive wheel...
I have a bearing with a 80.000mm OD.
I am machining a housing from 1018 steel that the bearing will go in.
There is enough load and stress on the bearing that I believe it needs and interference fit.
The bearing will be pressed in until it seats against a lip. Then a snap ring will go in...
Yep I would bin the subaru trans' front diff, plug the output holes and weld up the center diff.
Of course Subaru has had their share of transmission failures in may stock cars so they might not be the strongest thing out there.
However that would solve the trans to engine interface issue...
Well there are a lot of good points here.
This may sound silly but I had not taken into account the exposure to the sun.
I was basing a lot of my ideas on those cool suits that are made for race car drivers.
I suppose some of the open cockpit cars do see some sun but may not have the same...
All of these answers are in the range I have been finding.
I saw anything from 96 to 116.
130 is the highest number I have seen yet but I think that will give me a nice higher end to shoot for.
Incase anyone is wondering I am building a stirling powered cool jacket to wear when riding my...
With your extra HP output and such a small transmission I would venture to guess that the simple cooler you have in mind plus the extra oil capacity that such a system would add should do the trick.
Combine this with a good synthetic oil and all should be well.
That is, of course, if the...
I believe to make this a truely reliable system it will need a combination of methods that will help where ever they can.
I might sugesst a hydrofoil arrangement combined with retracting wheels and a redundant sealing system.
With the hydrofoil once you got up moving in the water the wheels...
You might try this place and see what they can do.
It seems they have a similar coating and process.

I know of a couple other sources in the US that can do this sort of thing but I have to track them down in some other threads on some other...
