Pillar bedding question

Post by Cherza » 25 Oct 2017, 1:38 pm

I have a norinco jw15 I want to put pillars in.
It has two action screws, the action does not make any contact with the stock where the middle screw goes so I was thinking about making a aluminim pillar that will make contact with the action and then glass bed it.
What do you guys think?

You would have to come up with some special shape pillars IMHO that you can anchor well into the stock. They are also using that front pillar or take down point as a recoil lug.

So what your saying is because there is not unough stock for the epoxy to hold?
What special shape pillars are you thinking?

Ok will check it out It may be out of my capabilities though.
When bedding is applied do we applie apoxy around that recoil lug and do I put masking tape around it for clearance?
I have bedded actions before but they had a flat type recoil lug I masked the front and sides.

I was under the impression that bedding in the stock should of been tight up against underneath the lug.

Ok thanks you have explained that very well
Do you think I am better off glass bedding the action from the front of the action to the back?
Leave out the pillars and leave the hole for the front action screw/recoil lug as it is?

Thanks for posting that pic Cherza. You have a difficult job in front of you. I still think you should bed the rear first. Initially, there is no need for a pillar. Remove the magazine and trigger box and bed in epoxy, the flat rectangular area of stock behind the mag cutout and half way up the sides of the action. Use Blu-Tak in front and behind the epoxy to stop it spreading. There should be a de-headed 50mm bolt screwed in to the action. Coat metal with release agent. Maybe wind leccy tape round the bolt. Clamp the barrel at around the fore sight in a padded vice, right way up. Install the stock from underneath. Use the long bolt as a guide. Install the front bolt loosely. Remove the rear guide bolt and install the take down bolt coated with release agent. Tighten each bolt say one turn at a time until the action and barrel are drawn down into the stock at their mid points. When you've got that done, we'll do a bit more.

Thanks mate I will make a start next week how much material would you take out for the epoxy or just a light sand just to help it bond?

Clean the stock with acetone. Use coarse paper and then drill say 1mm deep with a 3mm drill. Try to get the holes close together. Sand through the outer layer. Use a clean drill :thumbsup:

It's just a 22lr, glass bedding will be fine. No need for pillars with the torque required on 22lr action (king) screws.

Take magwell and triger off. Stop every recess with plastecein, coat action with a release agent, key the stock and fill with a good bedding compound.

Look up Nathan Fosyer's instructions on bedding at ballisticstudies.com
