white van man Posted November 28, 2015 Report Share Posted November 28, 2015 In the process of fitting a thumbhole stock to my RWS Titan. Any advice on which epoxy resin to use would be helpfull. Cheers Steve. Link to comment Share on other sites More sharing options...
MrCetrizine Posted November 28, 2015 Report Share Posted November 28, 2015 Devcon seems to be the de facto standard. Link to comment Share on other sites More sharing options...
The Gun Pimp Posted November 28, 2015 Report Share Posted November 28, 2015 Devcon is used by a lot of gunsmiths. It's way over spec for what we use it for but the main quality is lack of shrinkage. I use Loctite Hysol. Why? Similar price but better shelf-life (I rarely use a full pack at one go) plus it's an equal parts mix - so simpler than Devcon - if you aren't using the full pack.

MrCetrizine Posted November 28, 2015 Report Share Posted November 28, 2015 Just because this has piqued my interest, roughly how much material is used to bed an average action? Also how would a material like Sugru fair? Link to comment Share on other sites More sharing options...

I think that's due to the convenience of availability. Devcon is fairly available here. Acraglas is good, but a bit runny. Likewise people read the American mags and forums and hear about Bisonite and Marine-Tex and clamour to get them, but they are probably no better than compounds already available here. I'm sure there's plenty of Resins and fillers already available here that no one has considered already Plastic Padding anyone? Just because this has piqued my interest, roughly how much material is used to bed an average action? Also how would a material like Sugru fair? Not much, a few tablespoonfuls will generally do it, and I'd imagine most mix more than they need Never heard of Hysol, so may try that next time Thanks for the heads up Link to comment Share on other sites More sharing options...
terryh Posted November 29, 2015 Report Share Posted November 29, 2015 Selection probably down to personnal experiance and confidence, a hoobyist can play, where as a gunsmith needs to know the new owner has a working product. Think there are many 'other' compounds out there, Devon (in various formats and fillers) has been used for years, it works, but is expensive and does not come in small packs. Belzona's the same. Grey MarinTex is not an off the shelf product in the UK but I've found it easier to work with, consitancy of Devon clotted cream - caveat I'm only doing bedding for me not commercial. Also the £7 2oz pack is cheap and simple to use and more than enough volume for any bedding job. Hysol, a Henkel (aka 'Loctite) product also comes in many forms and has a longer working 'life' than Devcon http://www.henkel-adhesives.com/com/content_data/172023_lt4809_structural_brochure.pdf It's up to you what you use, regardless of which one just make sure you apply plent of release agent - then do it again : ) (BTW clear shoe polish is a very good and cheap release agent) T Link to comment Share on other sites More sharing options...

Is it suitable for bedding a rifle,I only ask as it seems to set a bit rubbery -flexible. Cheers Andy Link to comment Share on other sites More sharing options...
white van man Posted December 6, 2015 Author Report Share Posted December 6, 2015 I spoke with a local boat builder mate of mine. He has been using epoxy resins for years and has come across bedding guns before. He has recommended "West systems" and I've now used it. The mix can be varied from runny to putty which is usefull. I've also used an extra hard filler where a rail mount hole was out of line this can be drilled and tapped. So far so good, well pleased with the West System. Thanks for all the advice especially the link to the NZ guy on you tube. Cheers Steve Link to comment Share on other sites More sharing options...
terryh Posted December 6, 2015 Report Share Posted December 6, 2015 Andy, There are many types of Belzona, some are like for like to the 'Devcon' used in beding, Devcon itself has many verities, liquid, putties, filler of steel, stainless, ali based etc. Terry Link to comment Share on other sites More sharing options...
ejg223 Posted December 6, 2015 Report Share Posted December 6, 2015 One big disadvantage of devcon etc. is that one can't control viscosity or pot life. I like bedding with various different viscosities for the different stages of the bedding process or different types of bedding. We mix our own bedding compounds starting with an aero approved laminating resin system that's matches our stocks. We can then adjust thermal conductivity, strength, stiffness or hardness of our bedding compound. The complete bedded rifle is then oven cured. Saying that, if one only beds one rifle a year the devcon route might be safer and easier. edi Link to comment Share on other sites More sharing options...
dorg Posted December 6, 2015 Report Share Posted December 6, 2015 I use a lot of west systems glue and filler, I would be surprised if when dry it is dense enough especially as the filler is a very lightweight silica type powder. EJG223 you are obviously a very knowledgeable serious individual and perhaps abit more than the average man. All our stocks are bedded with devcon and usually do 2 or 3 to a tub and we use the age old method of adjusting the viscosity by warming it up. Never had a problem yet.

white van man Posted December 6, 2015 Author Report Share Posted December 6, 2015 Hi Dorg, I am using a 406 filler and have also used 404 high density filler to fill holes which will be drilled and tapped. 105 resin and 205 hardener is what was recommended. So far I am very pleased with the ease of use and the results. As I don't have heat pads the good old method of hot water bottles works. Steve. As for the knowledgeable serious individual you couldn't be more wrong (according to the missus anyway) Link to comment Share on other sites More sharing options...
