Chipco Racks - 66.7mm or 67.7mm? (1 Viewer)

They are likely not the same. I believe that anything branded "Chipco" has a wide variety of actual producers ranging from PGI as a lower cost paulson mold, chinese chipco mold, old "authentic" chipco's which are cloudy and slightly flexible, and Palm Gaming's chipco mold, and likely others. Each has different dimensions and pro's and cons regarding if you are stacking (how level the chips sit in the barrel) and width (how tight/loose the chips are, i.e. good for new vs used chips). I am currently weeding through all the various threads now searching for the same product details.
 
"Official" Chipco racks are all cast from the original Chipco mold and are the same size, approximately 67.3mm. They have a very distinctive marking:

The original Chipco racks were made from a more resin like material, they were cloudy and actually somewhat flexible. When Chipco assets passed to PGI, Joe made a bunch with the more standard clear acrylic material. But they're the same size. These are the racks that BRP now sells.

Not sure about the Apache link, at one point he offered 66.7mm racks with "Paul-Son" and "24010" on the mold, not sure if these are those.

If you're looking for 67.7mm racks (good for CPCs), your best bet is to get them from Dennis at Key West.
 
Oh wow, I didn’t look that closely and just assumed these were the same rack since both vendors sell them as Chipco racks. Didn’t notice the slight size difference.

I have a bunch of Chipco racks from Apache Poker Chips and they look exactly like that. Your photo is the ones BR Pro Poker sells? If so, then both PCF vendors are selling the same Chipco rack measuring approximately 67.3mm.

I think I need to buy a caliper o_O
 
My recently purchased Apache Chipco’s that look exactly as pictured also measure a hair over 67mm.

My Spinetti’s purchased, 66.7mm stamped racks measure a hair under 67mm.

New Paulson’s are nice and tight in the Spinetti’s. And just a bit loose in the Chipco’s.

Both are great. The Chipco’s are made with more plastic - perhaps more durable.
 
My experience with new Paulson in Chipco racks differs. I think they fit perfectly in Chipco racks and better than they fit in Paulson racks, which I find to be a bit too snug for new chips. I did not by my Chipco racks from Apache, but they look exactly like the one in the pic above and have all those weird lines. I don't know what those are all about.

I read a ton about injection molding today. Even though the mold itself is exactly the same as the original Chipco's, the final products from different manufacturers will have different barrel lengths depending upon the type of plastic being used, the amount of time and method to cool down the plastic, the amount of crystallization that the manufacturer desires in the product, and the duration the plastic is kept above its glass transition temperature (these are not unique independent variables of each other, but altered to attain desired compromise between durability, rigidity, and size). Manufacturers often use the same molds and adjust temperatures to attain desired changes in sizes. This is likely the chosen path here to use the same mold for different sized barrels as well. There is plenty of literature I found on this topic due to the necessity to size plastic gearing or other parts with small tolerances for changes in wear dimensions if replacing just one cog and the other is smaller, for example.

Therefore, identifying logos and markings will unfortunately not help to verify the barrel lengths and fit of the rack before purchase. So, the best bet to find an ideal fit for any specific chipset is likely to come from other chippers' experience found in these forums.

This confirms my experience with the chipco racks from BRPro, that Paulsons (especially casino-worn ones) have a very small amount of wiggle room. Their ceramics are VERY SNUG in these racks.
 
I actually like the 67.7 racks better for ABC/BR Pro ceramics than the Chipco racks they sell. I find them to be too tight in the Chipco racks, especially in the rows at each end which seem to run a hair narrower than the middle rows.
 
Don’t have any actual Paulson racks to measure, but I do have a third brand - Palm Gaming Int. They measure 66.7mm. The base is more narrow than others by about an eighth of an inch, which is helpful upon occasion. Nice racks as well.

There are actually two versions of the PGI branded 'casino' racks. The originals were 66.7mm, and later versions had slightly wider barrels by a few milimeters -- falling squarely between Paul-Son and Chipco rack barrel dimensions (66.7 -- 67.0 -- 67.3).

I have (and use) a lot of the PGI racks, because they have a smaller footprint and take up less room in pelican-style travel cases. But they tend to rock when stand-alone stacked, because the ID branding is located on the center barrel. Paulson, Unique, and Chipco branding is offset on the non-center barrels, and although not perfectly horizontally parallel when stacked, they don't rock on a high-centered balance point like the PGI racks.
 
Anyone have a digital caliper to recommend? I picked up a $10 caliper from harbor freight last night and the "zero" kept jumping from +30mm to -10mm. Maybe it was defective :banghead:

Before you write it off as defective, change the battery in it. Where I work we had a few of these brand new that just sat in their cases doing nothing until we needed them (like 3 years they sat there doing nothing) and all the batteries were dead.

One of the best selling and most accurate are the Mitutoyo calipers, but they start at around $125. I bought the iGaging caliper from amazon for $49 and it’s amazing. If you get an iGaging, make sure it’s an “absolute origin” version, as it resets to zero every time you slide it to the end. The one I got has inches, millimeters and fractions, but you can get one for $42 without fractions.

Thanks. I tried the extra battery that it came with and it was still doing the same thing. Maybe both batteries were almost dead? I'm heading back to harbor freight after work to exchange for a new one.

The Spinettis you are referring to, are they the Polystyrene 66.7mm?
 
I forgot to update this thread.

Maybe I don't know how to properly use a caliper, because my measurements are slightly different than @BirdCage . My Apache Chipco racks are approximately 67.5mm

As @Irish correctly guessed, I'm looking for racks to fit Chesterfields. Depending on how they're stacked, sometimes they'll fit snugly in my Chipco's, and sometimes they'll rub. Here's some measurements:

I have some unbranded racks I got from thechiproom back when racks were about $1 each that looks to be 69mm. These fit ASM/CPC loosely, but not so loose that you can squeeze 21.

Shoot Dennis a PM, those are the racks you want.
 
Slight thread hijack:

Are chipco racks better for ceramics? Sunfly 39mm hybrids to be specific?

My existing cheapy racks seem to have A LOT of loose space when full of sunfly barrels. ...ALMOST enough space to fit a 21st chip. o_O

I used chipco racks for mine. Is it perfect? No, there is still a little extra room in there. Will 21 chips come close to fitting in a barrel? Hell no.
 
Is PGI still operational? Their website doesn't seem to be up, or has been for a while.
 
Aha thanks, I obviously missed that.
I can't find any 66.7mm trays on ABC's website either though. Are there anyone selling these now (i.e. has them in stock)?
 
I need 10-20 racks for my BCC Chips can anyone point me in the right direction I am looking for the closest thing to 66.7 as poss without breaking the bank
