Default Made a Heatercore Shroud

Well, I made a few while I was at it. Once the CNC's are set-up it takes only seconds to run each individual part. The most time consuming step is welding and finishing the corners.
The heatercore is from A 1982 Olds Delta 88 and measures 10.5 x 5.5 x 2"

I made six, I am using one, so that leaves two that are welded and powder coated, and three that are bare metal without finished corners.
Send me a pm if you are interested. Shipping to the US would be about $15.00
And yes, they are made out of .048" (18 ga.) steel.

Are you willing to make others for diff dimension cores?

That could be arranged but it would need to be at least a batch of six.
May take some time also.

Those look really nice man Those measurements for that heatercore you mentioned, are those the fin area measurements or is that the total length including the tanks?

Dude, if you could mass produce these, you could probably make some serious dough . I dont think I have seen a well made commercially applicable radiator shroud for the bonneville core (which seems to be growing in popularity). wa261 sells both the radiator (painted and with barbs) and the shroud, but it is really not a good looking solution. Yours, on the other hand, looks very sturdy and professional.

Thanks for the comments. I'm not in a position to mass produce these. I can use the machines for short periods (during lunch hour) when they aren't being used for real production work. To mass produce, I would need to pay for material cost, machine time and painting. I can't see much of a profit but maybe people are willing to pay more than I think

The measurements are 5.5" x 10.75" x 1.5" so the small lip at the base sits flush with the finned area of the heatercore.

yup, unfortunatly its pretty hard to make and kind of a profit out of this kind of thing. Ive tryed building shrouds for astra hcores (very popular in the uk) but they take so long even to weld the corners its not worth the effort. They were aluminium and i cut them with a gillotine but its was not relly any slower than cnc. They look great when finished but i find peopel dont like paying over £15 for a shroud.

I came to the conclusion that the best way to make shrouds was by vacume forming and unfortunatly i dont have a machine for that atm

Your shroud looks nice. I used aluminium on one I made for a chevette core but I never welded up the corners. Just used some duct tape.

One might use a stamping press and hard tooling to punch them out in seconds without welding being involved. The problem with hard tooling is the cost and you usually can't make changes to your design.

I think people would be fine with unfinished shrouds (I know I am) because most of them will be mounted internally (although I'll probably end up welding it myself and then painting it)

I went and got one of RalphW shrouds, can't wait for it to get here and try it out. The extra 1/2 in. back spacing should help out with cooling and noise a little, plus it'll look tons better than the one I have.

Sorry, I wasn't clear in what I was asking I guess. Lets try this again ........ what's the total length of that heatercore (1982 Olds Delta 88). You said 10.5" but does that include the tanks on either end or is that just the fin area? Thanks

Just the finned area, it's the same part number as the 77 B-Ville heater core.

The total length of the heatercore I am using is 12.5"
The finned area is 10.75" x 5.625" which matches this:http://www.rockauto.com/ref/Stant/Detail.html?9078.gif

Maybe someone else can confirm that heatercore's specified dimensions are for the finned section and do not include the tank area.

Thanks guys.... /\ that's all I needed to know . I've just been looking for a good dual core that is under 11" long including tanks and can fit in a 5.25 drive bay which is why if it was 10.5" long it would've been perfect. I need to go through the HC database again . In general you add about 2" to the fin area length to get the total length including tanks right?

those are very nice

how thick is the metal you used for those and what material are they made from? are they aluminum or are they something that would have to be given a finish of some sort to prevent rust/corrosion?

they look really heavy duty.

yeah - I missed that on the first read thru - caught it on the second time.

Those should be really stout - I have made some out of 22 gauge steel and they are very strong so 18 gauge would be seriously tough.
