What would be a good wood to use for new bunks and would you treat or not? :confused:

Re: Wood for replacing Bunks?

I used pressure treated 2x6 (hemlock decking from Home Not so Cheapo), painted them with Jasco then stapled on new indoor outdoor carpet using monel Arrow staples. Did that about 1995/6 and they are still on the trailer. I haven't tried to make a detailed inspection and analysis but the original Doug Fir boards and carpet lasted twenty years so if I get that out of the new ones I'll feel satisfied. Oh, I did use stainless lag bolts to replace the original steel ones. There were no threads left on the originals.

Well, I guess it is depend on how long you want it to last. I just replace the bunks on my trailer. All the bolts are rusted due to 5 years dipping into the saltwater. The wood that were used for the bunks were regular pine. So I decided to go one step better and replaced them with treated pine wood. I hope the wood will last longer than 5 year. I would probably will have to replace the carpet before then.

Did you use stainless lag bolts? When I took the original lags out of my boards there were no threads left on them.

I prefer a good hardwood coated in bondcrete. Do you have redgum or merbu?<br /><br />Until fairly recently, redgum has been used for jetty pylons - 30 to 50 year underwater lifespan.<br /><br />Aldo

looks like good stuff but i cant find any stores in my area that carry it, on the web site it said lowes, ace ect. i went to the stores around here and they don't even list it. I was also thinking of using it on the transom and floor in my boat.

I don't think that we have any domestic rot resitant hardwoods. Anything we could get (Amazon?) would cost a fortune for 10 ft 2x6's

Have you guys ever heard of Valsper water proofing sealant? It also sounds like good stuff but just wondering if it works as well as they advertize? Also would you just use marine carpet or would short nap regular carpet work ok for the bunks?

Re: Wood for replacing Bunks?

I've not heard of Valspar. If I had it to do over, I would try a thinned epoxy soaking, especially on the open ends and up the pre-drilled lag holes. If you used pressure treated lumber, it would have to be thoroughly dry, any lumber for that matter.<br /><br />I just used regular indoor/outdoor carpet from home depot. It is made to get wet. There may be more exotic (expensive) 'marine' carpets available, but I'm not familiar with them.<br /><br />A good feature of indoor/outdoor carpet is its thickness makes it easy to wrap around the boards, especially at the ends, tightly. Be sure to use monel staples to tack it down. Regular ones won't last long. I also used contact cement brushed on carpet and board.

Re: Wood for replacing Bunks?

The trailer I have is a Cadet and the supports for the bunk boards were welded to the frame of the trailer and arn't in the right place for my boat, I had to cut the outside supports off and need a recomendation on what the replace them with the boards need to lay flat not on edge, I haven't been able to find supports that will let the boards lay flat seems all they make is for the board to stand on edge. Any Ideas??

I've been going through the same thing lately. I have a trailer that really wasn't set up properly for my boat and had to switch from fixed (welded into place) brackets that held 2X4's on edge to adjustable bunks.<br /><br />Two suggestions:<br /><br />First, if all you really need is a broader base of support and your current welded brackets support a 2X4 on edge (so the boat contacts the 2" side and the 4" side is bolted to the bracket), you might be able to simply replace the 2X4 with a 4X4 or a 4X6 to make a broader contact for the boat. Those two boards would have the same vertical dimension as a 2X4 on edge.<br /><br />As an alternative, it sounds like you actually need to find hardware to convert your set up to adjustable bunks because the existing welded bracket just won't work. This is what happened to me. What I did was go to a boat shop that had a variety of boats on trailers in the lot - their new and used and customers' boats that were being stored on trailers. I just looked at them until I found a setup that I thought would work with my trailer and boat. I brought the parts guy out and he looked at exactly what parts I needed and ordered them for me. <br /><br />In retrospect, I could have ordered the parts on line, but I wasn't sure exacty what I needed and found if valuable to have another person critique my plan and help order the parts. <br /><br />Basically what I came up with was brackets that attach to the cross members of my trailer which have swivel parts that bolt onto the new bunks. I can now adjust them up and down as well as in and out the width of the boat. The swivels ensure the bunks fit the exact bottom of my boat. <br /><br />Tnis is not unusual - this is how most bunk tailers, except for very small boats, are set up. There are a variety of brackets out there - a poster above gave you a link to the most common type. That type doesn't happen to work on my particular set up so I needed something a little different. But that's why I suggest you look at some boats-on-trailers to see what would work for you, and then find those parts on line or in a parts catalogue.<br /><br />While I was waiting for the parts, I made the new bunks. In my case, I made some 2X8 bunks (most people use 2X6, but 2X8 will work better with my boat and give me peace of mind). <br /><br />I made the bunks out of all pressure treated wood and covered the contact surface with UHMW plastic using countersunk stainless screws. For my boat and usage, UHMW works better than carpeting. If I were to use carpeting, I would have bought it at Home Depot rather than the boat store. They have some all weather grey rubber backed carpeting that looks identical to what they sell as bunk carpeting, and it's about 1/3 the cost.<br /><br />If you need any more suggestions on this set up, let me know.

I have a couple of old trailer and was thinking of taking the brakets off one of them they mount the boards on edge and then take 2x6 and bolt them flat on the edge of a 2x4 think that will work? my boat is about 17' but is light even with the 7' beam weighs 525lb dry weight it aluminum 1959 Texas Maid with a 70hp Johnson

Re: Wood for replacing Bunks?

Something happened in the middle of a note I was writing - so maybe this will turn up twice.<br /><br />Anyway, that's one of the first things that would have come to my mind as well. It was an option I considered with my own boat - which weighs (with engine) probably 3X yours. It didn't work well with mine just because of the way the keel rollers are and some other factors. But, if the 2X6's end up in the right place on the boat if they're bolted on top of the 2X4s it might be worth a try. Dont' skimp on the bolts though!
