Building An Oil Cooler

[machinest]

Thinking of building an oil cooler basically of aluminium square end tanks and round cross pieces all dip brazed together.



All passages to be 3/8 dia. and the round cross pieces to be slotted/finned from 1"down to 1/2" with appropriate fittings in the ends of the tanks.
Will this work or will I need more cooling surface? The rods will be 6"long and the piece will be 41/2"tall.

you should take a close look at an OE or Earls cooler ;I hate to even guess how much more surface area it would have. Pick up a GS550/750 rather than build one. Gearhead has one for sale for $20 plus shipping................

I know that but I also like to make my own parts as much as possible just to show I can

[madjack57754]

I would ball mill the tubes to create more exposed surface.

[machinest]

planning to turn the tubes so they will actually look lice a series of 1/8 (actually .085")disks with the same size slots between.

[madjack57754]

Using something along the lines of a modified parting tool to cut in a cut one, leave one pattern?

[machinest]

YES the shops smaller parting tools use .085" inserts

I can really appreciate craftsmanship and all but I don't see the point of making an oil cooler since modern tech is functionally superior to any cooler with large round tubes like you can make yourself. My suggestion is to get yourself an Earl's radiator and then focus your attention on execution; make a really killer distribution block and integrating the entire assembly into your particular bike as cleanly as possible. I did that on an oil cooler setup for an 850 and had a lot of fun during the process. There is actually a fair bike of tech that goes into the distribution block so drop me a PM if you want to discuss.

Good luck.

Using round tube isnt very efficient, reminded me of lessons in computer water cooling. Smaller and/or flat tubing works better. This pic kinda shows why:

Not trying to be a smart-ass but I hope that you are a better machinist than you are a speller. (machinest)
Which reminds me of a joke: Yesterday I couldn't spell machinist, and today I is one.

Yes I know what you mean happy dyslexic here,(thank G-D for spell check). Only problem is I have occasional run up left handed parts rather than right handed . My Foreman is also dyslexic and has been known to do the same thing ,usually the inspector catches the first piece so not too much damage done.

Think I shall invest in a voice recognition program to make this web stuff less difficult

Also will defiantly pressure test this before it goes on the bike

And so did you.
