A friend has an RPA action in a synthetic stock.....it needs proper bedding.

Any advice about materials to use etc., please.....

There are some quite good Youtube videos that seem authoritative (although I'm not an expert). This one seems credible: http://youtu.be/IyPQF-64-sA

I have done a couple of my own rifles and used http://www.jbweldadhesives.co.uk/ on my .308 and http://www.devcon.com/products/products ... %20%28A%29 on my .223.
The reason for using a different product on the .223 was basically that I didn't have enough JB Weld left to do the job and my local supplier had run out (local farm machinery agents). If I had to choose between the two, I would choose JB as it was easier to work with and gave a great finish (and very strong as well)-just my opinion thou.
I watched a few tutorial video's of how it was done and took the plunge and am very pleased with the results, just make sure that you use plenty of release agent and don't drip any of the compound on the carpet (I am still getting grief after two years )

Yes - take it to someone who knows what they are doing!

Yes, agree with this sentiment!

But to answer the original question, stainless steel filled devcon is the thing. Don't forget the release agent on the action as this can be embarassing otherwise!

Gaz

PS - If you do forget the release agent, remove as much accoutrement from the rifle as you can and put it in a chest freezer for a couple of hours. This should separate the action from the stock.

Thanks for that.....I will pass the info on to my pal.....

I use Devcon Plastic Steel Putty and buy mine from HS Lawson who stock it at a good price.

I machine my own pillars to suit the rifle. Do make sure you get a reasonable depth of Devcon or whatever you use in place as a light skim is all but worthless.

Boot polish makes a good release agent.

It is not a difficult job however it is quite time consuming.

Answer me this...

Is bedding really necessary on a modern firearm? When wooden stocks ruled the world, few things could improve the accuracy of a rifle as much as bedding.

I have rifles with alloy bedding blocks and the action mates to the block, which should result in a solid metal-to-metal connection between the receiver and the bedding block.

Obviously, this interface depends upon the accuracy of the machining. Would the rifle benefit from a small amount of bedding compound to ensure an accurate interface?

I used to use Devcon and found it very good in every way but moved to JB Weld as it is even better, easier to manipulate, a little bit priceier though. So if you are on budget Devcon will serve you well.

Even with bedding blocks the action is still stressed. With my T3 project with the rcs chassis system I will bond the chassis to the action(just like an AI AW) then there's no stress;)
