Prototype Delrin 'DelRez' Reservoir *56K Warn!*

[ElMoIsEviL]

I'd get one at the top of the case and add an LED into it. Would look nice.

You could get these as I dont see female to barb: http://www.legris.com/legris_com/Pro...&sf=01&ty=0902
Part #: 0902 00 17

Then just get a 3/8 BSPP male to hose: http://www.legris.com/legris_com/Pro...&sf=01&ty=0931

Perfect, thanks!

Pricing update:

Delrin Cost = $14
3 Legris Plugs = $1.80
2 Barbs = $5
12 Button Allens = $1.15
O-Ring = $1.50
------------------------------------
Parts Total (Glass not included here, included with machine time)
$23.45 <---- not too bad IMO, but alas, there could be a 15% - 20% variance here.

Machine time, gulp. This is for the Delrin body, to lathe, groove, drill tap etc.

50 pieces = $27.15
100 pieces = $24.02
200 pieces = $22.05

The glass is higher than I expected but whatever. Actually now that I think about it, it isn't THAT bad. I had estimated that the glass itself would cost $3 per piece so $3.31 to machine each one seems reasonable, just a bit higher than what I had in my head though. Again, the below pricing INCLUDES the material and labor.

50 pieces = $6.31
100 pieces = $5.52
200 pieces = $5.08

So to sum it all up, lol, the materials cost is not really going to change as I never plan to do a huge quantity of these. My plan for now, is that if there is enough interest, I will do a run of 20 pieces and take it from there. I still don't have pricing on the mounts, the bay mount or the square top mount. I can't imagine the square mount to cost more than $10 or the bay mount to cost more than $30.

So for just the reservoir with all the parts but no mounting costs are:

Parts = $23.45
Delrin Labor = $27.15
Acylic Part & Labor = $6.31
TOTAL COST = $56.91

I imagine I'd sell them off for ~$75 or so.

*Edit* is there this little margin in most watercooling gear? Heh, I'd hate to see what I'd have to wholesale these for

Most computer equipment has a margin of 10-15%. Yes it's VERY small.

You ought to focus on options to reduce that machining cost. I'm not sure you'd sell a lot at $75 ea. Definitely a one of, short run.

The only way to really get the costs down is to do a lot of them, like 500+ Not much I can do. Again, not doing this to make money.

[bigben2k]

Bummer. Isn't there a way to get the Delrin as a tube, instead of a rod / cylinder?

[ElMoIsEviL]

$75USD... I'd still buy one... but it would have to come with the fittings.

Gonna be hard for you to put everything together and sell them at that price if the person still needs to buy fittings, nobs and the plate.

[starbuck3733t]

Awesome!

The res will come with fittings, glass, oring, barbs, plugs. Just no mounting plates, those will be extra... I have decided to try to adapt the res to fit the aquatube mounts so that those that have aquatubes can just drop this one right in, a direct replacement so to speak.

Yeah, but i dont want to go that route... I dont want to have 2 end caps.

for gods sake ben, i said that in my post earlier...

The only way to make these cheaper is to design them cheaper - which doesnt have to mean inferior. I cant imagine theres much margins at ALL in watercooling gear, hence swiftechs recent moves to injection moulding + slitsaw design. Take a niche market, then add high machining time to what is essientally a low cost item... injection moulding makes 100% absolute sense really, when you're talking a sustainable company.

If you dont have access to 'at cost' machining, things get expensive pretty quickly... the thing is, there doesnt need to be much machining at all in these if dual endcaps were used, which realistically doesnt increase risk much.

[bigben2k]

Yeah, I know you did...

Looking up distributors for a related product, I came across these:
k-mac-plastics.net
portplastics.com
acetal-rod-sheet.com (dead?)
phenolic-sheets-rods-tubes.com
sdplastics.com
calsakplastics.com
professionalplastics.com
modernplastics.com
plasticdistribution.net

(Some of them are too pricey)

[ElMoIsEviL]

Wouldn't any of these work as well yet cost less???

Nylatron GSM, MD, GSMK or PA 66.

[Etacovda]

yep, but theres a lot of acetal fanboys around

nearly any non-clear plastic would be fine, assuming it machines well.

[bigben2k]

Soft plastic is the key. PolyPropylene, ...

[nikhsub1]

Yes but acetal is very nice to machine, has ultra low absorption, high tensil strength, and looks killer.

[Etacovda]

strength - not really required in the thickness/tolerances being dealt with, barr threading
low absorption - how is it compared to vinyl? because thats really the benchmark
machining - again, not huge amounts of detail so as long as it machines 'adequately' then yeah
looks - yep, it does look nice when machined right, but then, so do a lot of plastics.

Im sure theres a cheaper alternative out there, its just up to someone to find it.
Im absolutely certain with some work it could be made significantly cheaper.

Im not putting down the res, btw - sorry if it comes across that way.

[ElMoIsEviL]

After comparing Nylatron GSM to Delrin it seems both would be perfect but GSM costs about 1/2 the price. Both also look killer.

Definatly should look into that.

[gmat]

$75 is an adequate price IMHO. It's in the right ballpark of other reservoirs on the market.
I suppose that if i want to top mount it, i just need a blow hole of the right diameter, and 6 holes around it ? Would there be a nice way to refill it from top, like a screw cap ?

That's for the RES alone without fittings or the bay or plate mounts. It's a beautiful design and I totally want one... but I'm not convinced on Delrin being used as it seems like such a waste when comparable hard durable plastics are 1/2 the price.

I mainly say this in terms of making some dough from this project. Nik could easilly sell them for around $65 USD with all the fittings etc if he used a cheaper material such as GSM and still make a respectable profit. Would also be perfect to sell to OEM's at a reduced price while still pulling a profit (wholesale).

Nylatron GSM

Oh and a supplier that carries all plastics in rod form.
Professional Plastics

What Diameter do you need?

Yes that is the res but it has all the fittings, barbs, glass, oring etc etc included. The only piece not included is the mount plate, which AC and innovatek also sell seperately. I am using 3" diameter rod.

[nikhsub1]

Nylatron is $35/foot... in 3" diameter. I can get Acetal for the same price, no savings there.

Then in that case... were do I sign up?

From your supplier you could probably get Nylatron for less then that website then.. It should be about $15-20USD less per foot.
