Folks,

I received the following question via back channel and I am posting original question and my answer here for all:

Can you tell me where you got the HDPE ?? I presume it is in white finish ? It looks like you left the screw heads exposed ?? Did you have to cut the angles for the toe rails ?? That is a nice looking installation. Thanks.

My Reply:

First this message should have been asked on the O'Day owners forum. Others have done similar things and others would be interested in the question and reply. That is what the forum is all about.

I live in Greenville, South Carolina and used a local company that sells plastics and cuts plastics such HDPE:

http://www.dixierubber.com/

Therefore shipping was not an issue.

I also bought from them 1 inch nylon rod to replace pivot for swing board.

Since I did project, a number of companies began making Teak look alike plastics. That stuff for the most part is HDPE and UV inhibitors with color added.

All the stuff I had made was white, but if I was willing to wait, it could have been black.

I have a table saw and a router so cutting lengths and rounding edges was doable by me. But Dixie would be willing to cut to specified lengths and round corners. That is really how they make their money. That is custom cutting plastics for customers, not merely supplying raw material.

If you look at their web site you will see that they supply other kinds of plastics other than cheap HDPE. In fact I have an order in right now for some Delrin sheaves to rebuild some blocks.

Note that I am posting question and reply on forum.

I have replaced all teak with UHMW polyethylene (ultra high moleculer weigth )
The product is TEVAR 1000, very workable with power tools router ecet.
The product is black and close to teflon not as slick but more abrasion resisten
through personel experimentation it can be glued with an uruetane used for windsheilds
maded by DOW but you must use the primer that they recomend for it

JM,

Great comment about using windshield glue is timely. Do you know the specific name or number of both glue and primer?

I use a 3m product that is butyl rubber based, I do not have the tube handy but think the number 08509:

I hope Richard is following this exchange. It illustrates the reply I sent to him.

Also, similar discussions have be posted in the past and are in the 'Archives' kept by Captain Herring. Our 'Liberal' captain from Alabama is expert on instucting how to find things in archives.

The butyl rubber products are becoming hard to find because they use solvents that are 'hazmat'. Whereas chemist have found new stuff that is not hazmat and solvent based. I do not have experience with the new products designed to get around hazmat solvents.

However, NP-1 a product used by roofing industry does have a following amoung sail boat repair yards.

Richard, isn't it amazing what we learn from a free exchange of information?

Freedom, worth keeping.

Replaced my teak with Azek this spring and I really like it. Sank all the screw holes with a Forstner bit, used bungs I cat from scrap and bedded everything with Butyl tape from Compass Marine.
Had I used teak, not only would it have cost me 5 times as much but I'd be recoating the varnish right about now.

The product is BETASEAL U400HV (high viscosity) need to warm it up, I put the tubes in a thermos of hott water for some time. Glued most of the stuff with it. Also U 418 which has the consistancy of regular cauking good for sealing. The primer is BETAPRIME 5404A.
Will send photos as soon as I figuer out how JM

Very timely discussion. I'm planning an HDPE gas locker that I can properly vent. I'm not so concerned about gluing as I expect to screw and caulk the locker which will not be visible.

Thanks, I'll try to get a few close ups soon, a tip, even if the primer does the job of opening links in the subsract I roughend the poly on a band sander before apply it.

I recently received an email about sources for HDPE. This thread discussed the topic some time ago. Here is copy of my recent reply:

I just reviewed messages. I cannot tell if I replied.

There are several sources of Teak Substitutes, that is modern plastics.

Some do not say teak substitute rather use words like outdoor materials. Sometimes these modern plastic substitutes can be bought at Home Depot or Lowe's. Thought they are usually in white.

Some building supply places do not stock but can get in single boards. If you get a 1 x 8, you can cut into several to do toe rails, etc.

The fancy cuts of the cabin slides required a thicker piece and several cuts on a router. I guess you could get a router tip to make less cuts, but I just made several passes using several tips.

I rounded all upward or outward facing edges.

I used existing deck and cabin top holes but I know one guy who filled all old holes with epoxy and redrilled all new holes to make perfect matches.

The trick is to find local supplier of a plastic substitute rather than ship. However, if pushed have them ship in shorter shipable pieces.

I have a local supplier and used white because he stocked it. He also stocked some black.

my supplier:

other suppliers:
