Craig here... I'm good for a set! Commander #229
Include Commander #270 for a full set also.

Pretty sure that's the case. The original order was based on the Ariel which has two different extrusions. When we later added the Commander, the only difference was the length of the smaller forward hatch extrusion.Quote:

Regarding the different extrusion issue; I have the new extrusion on BOTH the Lazarette & the fwd hatch and it works wonderfully for both applications. It has held up very nicely. -I've actually never seen the other version.
Bill,
I'm definately interested in making a purchase for enough to redo Ceili's forward hatch and lazarette hatch.
Jerry,
I had to go confirm for myself (the measurements you provided from Destiny) and obtained the following from Ceili:
Forward hatch: 75-1/2" (6' 3-1/2")
Lazarette hatch: 116-1/4" (9' 8-1/4")
Total linear inches for both: 191-3/4" (15.979 feet)
The above dimensions have no additional length added for allowance of fudge or adjustment.
I too, would like a couple of extra inches to work with. I would think that the material (gasket extrusion) is bought and sold by the linear foot. With that being said, I would like to have 17 feet. (Jerry, same as your input)
Like Jerry, I was also under the impression the size (profile of the gasket extrusion) was the same for both hatches. Unfortunately I no longer have the forward hatch gasket that I removed from Ceili for reference. I do however, have the remnants of the lazarette gasket I removed and have attached photos of.
The lazarett gasket I have in hand (the old that was removed from Ceili) does fit on the forward hatch fiberglass lip just fine.
I would be interested to know the specific differences in the two profiles as indicated by Bill (referring to the original order that was based on the Ariel)
Bill: Do you have the profile dimensions of each extrusion that you make reference to?
Rico: You mentioned that you used the same (new) extrusion profile on Mephisto Cat. Do you have a piece in which you can obtain measurements (height and width), etc.?
Yes, I still have a few bits of the original. (When I say new / original - I believe it is the material supplied to me my the PA Association - via the PO). -The old 'original' material on the boat was the stuff I took off during the restoration, which I believe may have been the factory material. these were virtually identical...
Fom the discussion we had on this issue: (on the Mephisto Cat thread Post #52 0nwards):
http://www.pearsonariel.org/discussi...5-Mephisto-Cat (See Below).
This looks to be a bit larger than what you've pictured... Perhaps you have the misterious fwd hatch version (??) I will post pictures similar to yours as soon as I find the extra bits...

The profile is as pictured and the specs follow the original material. They are as follows (Catalog picture for measurement reference only:

This original material mirrors these same dimensions as the original Pearson Material very, very closely, but the original stuff is all solid rubber, The material from McMaster-carr has some sort of soft foam at the top - not hard rubber, while the bottom part is a hard plastic with an aluminum core... I am afraid that this replacement material pictured would not last very long for this application.
The Dimensions are as follows:
Edge ........A.........B ............C
3/16" ..... 5/8" ...17/32".... 1 5/32"
Go with what Rico says.
But, I've been over those catalog pages dozens of times.
That edge-grip rubber seal is the only one McMC has readily available that remotely can be a alternative.
Quote:
"EPDM Seals with Vinyl Grip - These seals have good weather resistance.
Gripping portion is made of PVC with individual aluminum clips (unless noted) inside to ensure a permanent, secure grip.
Bulbs are EPDM closed-cell foam rubber. Temperature range is -20 to +150. Color is black."
EPDM foam can be quite stiff. The problem comes with rubber taking a set, no longer springing back to original shape after being under pressure.
Got some 1/8" EPDM foam sheet in the shop that is quite tough and heavy and springy.
Wouldn't know it was foam unless you knew it was foam.
In fact the bulb with hold its shape longer in foam than if it was hollow 'sheet', imco.
Don't know about the metal 'clips', but it seems that it won't matter too much. Maybe they are removable. Maybe they help to keep the seal on when something is lifted out of the well. Maybe don't have to glue the grip on!
Ask for a sample, or pay for a foot. Nothing works better than seeing and feeling the stuff.
It's going to be around $50 plus UPS for 20'!
Ebb,
BTW - I did order a bit of the McMaster Carr alternative I showabove. The stuff is not worth even attempting for our application. It will be ruined right away - it is waaaay too light & flimsy.
Dang.
Life ain't easy, but it sure is a lot of fun.
Our mason here on the estate says that when disappointed.
You know I'm redoing with epoxy the inside of the cockpit seat lockers so that the gutter framing system is all continuous and the same level. Which it sure as hell wasn't.
Will find, hopefully, some peel and stick foam that will apply to the lid - rather than the edge around the locker which will always have stuff dragged in and out.
Let the lid do the sealing.
SO, why not just finish off the thin sharp fiberglass deck openings of the laz and forehatch with a nice round rubber thingy.
And have that meet a foam kissing cousin stuck on the inside of the lid. OUT OF THE WAY!
WAH LAH
Huh?;)
Your association went through all the various weatherstripping alternatives years back. There may be a thread someplace, but it could have been lost when we changed over from the Microsoft created discussion board. We obtained samples of the available weatherstripping and found that none would do the job. That's why we ended up with a custom extruder.
As noted earlier, the minimum order requirements mean a substantial investment. And , as noted, it took over five years to work off the inventory the last time. We are a bit hesitant to do this again, as the expressed demand has not been very great. I think our minimum purchase equals about 50 or so sets of weatherstripping. (I'm not near the records at this moment, so I'm not positive about that.) That could mean sitting on a substantial investment in rubber for an unknown length of time.
No decision has been reached. :confused:
Bill
I must be missing something. In your post # 35 I understood that the minimum order was only 100' of material. If I'm willing to buy 34' by myself and several others are willing to buy 17' lengths we should be able to reach that pretty easily. Obviously I'm missing something. Can you help me figure out what it is?
I too, am confused. Help.
Bill, if the original order was 186 and 300 feet, with the 300 presumably being for the lazarette hatch extrusion, how did you come to the 50 set value? 300 feet would really only support 30 hatches (each lazarette hatch requiring 9.6875 linear feet, excluding any additional inches for allowance of peace of mind).
There you go again . . . I'm 300 miles from my desk and winging it! Maybe it was 30 sets, but 50 popped into my mind. I'll return next week and try to make some more mistakes:cool:
Mike Here... I'm good for 2 sets! Commander #38
My Name is Arjen de Boer and own Ariel 235. I would love to have a set or two of hatch and Lazarette Gaskets.
