JABROCK
Are there any domestically produced densified plywood products comparable to Jabroc?
If you buy a suit in a London shop, it costs $2000.00. Buy it in Chicago, same fabric, same cut... it costs you $395.00.
Is there something available here (a Marine plywood?) that will scrape the ground just as stylishly as Jabroc seems to?
Thanks ---
Ha!
Not sure if I agree w/ the suit comparo, BUT, if you put Jabrock on an F1000 car it's gonna be a first. That stuff weighs tons!
The RFR F1000 came with a birch 1/4" or so layer attached to the main floor...
I've used Jabrock on an F1000, so he wouldn't be the first. But some cars are light enough by design to do that.
Thanks
for taking the bait Josh, you even beat the 15 minute deadline!
Nice try, but no one believes you were trolling.

have said jabrock on the car @ WGI a few years ago? That might 'splain it.
(Oh no he di-ihn! - Yep, he damned sure did!)
Yep, but even if I had a truckload of Jabroc on it, removing it wouldn't have made enough of a difference.
Cool

We hijacked.
I'm not aware of a product equivalent to Jabroc at a lower price, and I have only ever seen it in metric thicknesses.
We have used UHMW sheet in 1/4" and 3/16" thick. It is great stuff and can really handle the abrasion. It is not as stiff as Jabrock but stiff enough imo.

PS; You need to search around for the best price as there is a big range from very inexpensive to very expensive.
when I built up my car for the first time in 2002 there was an old guy in the LA area that distributed Jabroc out of his garage. I bought a full sheet of 4mm for about $400. Over the years that made a set of front sidepod floors, two sets of rear floors, four front skid plates, and a host of other doo-dads. Unfortunately there's not enough left to make more than the occasional spacer or two so I'll have to see if the old guy is still in business sometime soon.
If I had to do it again I'd use the 6mm.
You can always get quality plywood from aircraft spruce.
UHMW[ ultra high molecular weight] polyethylene at present is $23 for a 12"x24" and $290 for a 48"x96" 1/4" thk. sheet from Grainger[who are national]. It is avail. in other thicknesses. The 1/4" works great on the front wing shoes of my VD F2000. Should outlast jabroc and does not splinter at about 1/2 the price.

Thanks, everyone!
And another question -- Lexan?
Again, thanks,

What about Delrin? I s it too soft? We used to use those on outriggers back in the day. You can get strips on McMaster. Jabrock is fancier as the F1 guys use it and Matchett mentions it from time to time so there is that.
I think my Stohr had aluminum pucks.
PS Are you talking about wear strips or for a floor section?

Typically you can get uhmw for much less at your local plastics supplier. They usually have some drops or misc pieces for very low prices. Great stuff IMO.Originally Posted by TED K.

UHMW can work, but Jabroc is about three times stronger and 20 times stiffer, which is useful when you are trying to minimize the number of attachment points and prevent "sag." I think Jabroc would last considerably longer than UHMW, but I haven't done side by side testing.
EMI Supply used to import Jabroc, and that's the last place I got a full sheet, but I've heard they are no longer distributing it. Might want to contact Permali Deho directly and ask them where you can get it in the US:

If you find out anything, let the rest of us know!

Pegasus has it but not full sheets. 19.5" xd 39" is their largest

Interesting - last time I looked they were a german company.
Give me a call - I can get it for you from my friends who are the local distributors (plus I need to get some myself for my projects). I think that they get it out of Canada, but could be wrong. It ain't cheap, and shipping cross-country doesn't help the cost at all.
We've use jabrock a lot over the years, and it is well worth it. It will really take a pounding, won't sag, and can be bonded to whatever you want. Jabrock is nothing more than resin impregnated and compressed birch (or beech) plywood - incredibly "low-tech" material with great performance.
How about Baltic Birch plywood?
Baltic Birch is very well known for it’s strength (bending properties) and wear resistance, that is where you see 4×8 being used as industrial flooring, container flooring and other heavy duty flooring applications. Just sheer life span and resistance to abuse of Baltic Birch flooring is amazing. BTW it's pretty light and pretty cheap
How do I know all this? I just googled it and did the old copy and paste trick.
You may want to consider the previous ApexSpeed advertiser:

They will CNC cut/fabricate whatever you want in small quantities. I got a quote on the skids I use for my front splitter, and it was like $17 ea, with tapped holes for mounting.
Lignum Vitea or what we know as Ironwood could be a substitute. Hydulignum Densified Wood Laminate is another choice.
Baltic Birch will work, but it is nowhere near as wear resistant as jabroc since it has not been impregnated nor compressed. A ton cheaper, though, and easier to find locally at hardwood shops.
Chris:
Got pieces (4mm) being delivered tomorrow. E-mail me your address & I'll get a chunk sent out by mail.
