Redoing floor and stringers in my 85 22 velocity, what materials did they originally use to build these boats? Any recommendations what to use for resin and glass?

thanks

Check out boatbuildercentral.com for supplies. I used System Three Silver Tip epoxy resin with very good results on my Shadow bass boat resto. Would definitely use again. Drop me a pm with your email and I can send you my material list. Good luck!

Real simple , polyester resin, chopped strand matt, and woven roving !! its all anyone ever uses even to this day !! don't have to think to much using those materials . BUT remember if you start using epoxy you are committed to always using it for ever more as poly and vinyl should never be used over the top of epoxy's as it would bond to good !!.

Bull $hit , and talk about old school fabric ( woven roving ) considering i know more then one person or Boat Co that is almost giving it away , and for the likes of me why would anyone ever want to use that combo of fabrics with Polyester / Vinyl Resin when # 1708 is readily avalilable which is much easier to work with , and not to mention that #1708 has a 45/45 Glass +stitched or sewn 3/4 ounce Chop Strand Mat backing ( CSM ) that is a high strength fabric which is a very commom Biaxial that is used in the industry .

woven would have been the original materials used for sure !!But for doing repairs etc 1708 as you call it is easier to lay , easier to work with and as stated its a combination of double bias and csm all in one , make sure its well wet out ! same weight as the original that was used just its not woven so lays flatter , best to use for rework with epoxy rather than polyester !!

Tunnels , not to be rude but every Boat Co that i have ever worked at who was using Epoxy in there build never used # 1708 because CSM has a binder ( glue ) which is designed for Polyester resins and though they are sometimes used with Epoxy resins with satisfactory results , the binder may cause clouding and prevent thorough wet out ( Not Recommended To be used with Epoxy resins ) considering #1700 Biax ( is a matless cloth - no CSM ) that would be a far better choice of fabric to use with Epoxy which would require less resin for a thorough wet out .

You are a little behind the times !! most every matts and fabrics that has csm attached does not use any binder because its stitched !!so the light layer of csm is also used as a soft cushion layer that's glass reinforcing the resin layers between the fabric layers . All this is a well documented fact written by the fabric manufactures !! I also had question this some time ago !! You really have to keep up with the times there always a good reason when glass companies make changes , may not be obvious at the time !! while we are on this subject you can use csm P matt with epoxy resins and this is also well documented by a reputable and very well know epoxy manufacture . times change and what we thought yesterday has changed while you been sleeping !!also most of the glass fabrics sitting on shelves almost any country these days are manufactured here in China or Korea .We have glasses here you could only dream about that I have never seen any where else . we are able to get glass widths that match what is required for specific jobs so there's no side joins

No $hit Sherlock , and to tell you the truth i most likely have a better working KNOWLEDGE of the the latest and newest materials that are being offered or used in the build of Epoxy boats , and once again why would anyone want to use any fabric with Epoxy that has CSM involved in there build considering ( csm ) can be your weakiest link ( needs twice the resin to wet out with a very low tensil strength ) which is a low cost ( CSM ) general purpose reinforcement , and why would you even want to consider using that fabric when there are others out there designed for Epoxy use such as ( E- Glass , which is the most widely used and economical reinforcment composites in the industry ) with S - Glass not far behind but having a much greater tensil strength ,and all around toughness which is more expensive then E- Glass ) which is most commonly used for high performance applications along with Kevlar , and Carbon fiber . Tunnels , to tell you the truth China , and a host of other builders on that side of the world most likely are building nothing but junk with a big buck price tag with poor workmenship to boot because people in those countries have no concern for quality or pride in there workmenship .

thank you for the replies guys. I was kinda leaning to using poly or vinyl due to cost and also i was planning on gel coating the floor when i was done. i am also going to be replacing the transom while i am in it this far, found a few soft spots. i am going to be using 3/4 marine plywood for both transom and stringers. what is a good layup to use for the transom? 1708? i have not done a project this big yet but have done other fiberglass projects with sucess. also any tips or trick or any ideas that can be incorperated into this project that will clean up the boat? thank you guys for they help i really appretiate it

Yes by all means #1708 would be a good choice for your layup considering you are planning on using Poly or Vinyl , and might i suggest pre making your transom board on the bench , and to tell you the truth when ever i do a transom i always go with this sequence ( 1708 in your case ) two layers of glass ,ply , two more layers of glass , ply , and two more layers of glass , along with using multiple layers of fabric staggered around the perimeter of the transom & hull sides , and three layers of fabric staggered when doing stringers which to some just might be overkill considering i am somewhat old school and always have been a firm believer in a little more beef which actually is an old habit from working at a certain Boat Co . 85 Nova ,i truely apologize for the miss direction of this thread .

while we are on this subject you can use csm P matt with epoxy resins and this is also well documented by a reputable and very well know epoxy manufacture . times change and what we thought yesterday has changed while you been sleeping !!

Tunnels please do not tell me that the documation by a reputable Epoxy manfacture was West System considering i once worked for them in my early teens and had the opportunity while i was employed at one Boat Co using there products ( Pro set ) drop there line of products because of all the bad information or compatibility issues .

Tunnels i think most of the people on here and other sites www.boatdesign.net will agree that you are a bigger problem , and a person who always seems to have an Ax to grind considering you ( even though your visits are short and in between ) always seem to start some sort of trouble while you are here , and from the looks of things the only reason why you are here is because you now are a previous member of www.boatdesign.net .....................http://www.boatdesign.net/forums/fib...ing-48101.html which is a very hard thing to achieve on that site with all things considered . Take Care , my friend.

Post lots of pictures of your build. This winter I am going to redo my velocity 22 that was a inboard going outboard
