Use plenty of release agent....
Crossbolt then epoxy?
Ha ha :thumbsup: This all gave me a laugh last night VC :D I don't feel quite as silly for my efforts ;)
Put in pillars before bedding it?
I would go all out, cross bolts and pillars epoxied in and the bedded, shouldn't move after that.
Nugget?Quote:

VC,,,,,That crack is a known fault with the 75 synthetic. Mine did the same thing years ago and was replaced with a new stock, by whoever was the sako agent when they were the current model.....
Yep....3 seperate stocks I have looked at had it to varieing degrees.Quote:

Bit of interest again after the Toby shoot and went up the range to continue developing a load I started on ..... I dunno bloody ages ago and it shot like shit even with a known load.
Not the rifles fault but when I pulled the stock off the front screw was a full turn out from finger tight [emoji23]
Iv found with 85s and 75s they can loosen after 10-20 rounds after refitting the stock no matter how pedantic you are with setting the action rearward while tightening but after the second tighten they are generally rock solid.
Mine has done a lot of bouncing around in a fish bin on the front of a quad,being carried/dropped/walking sticked and generally taken hunting but not to the range.
So while it shoots pretty good if the action screws are actually tightish its just something I should sort out I think so hopefully they stay tight.

It's not an easy action to bed....lots of corners and angles.
I've done two of these synthetic 75 stocks. When I dremelled out the action holes to take Devcon and pillars, I found that there's light gauge steel pillar like fittings embedded but not visible in the stock. They must be there to stabilise the synthetic material around the action screw holes, and prevent it from being crushed under torque loads.
I've also done two Senator '75 stock with pillars from Dean Maisey and Devcon 10110.
PM me your cell if you want to chat about it. I've got some good silicone faced adhesive tape you can have that's good for relieving the areas that you don't want any of your bedding compound to contact, and load the action up.

Just Stug it VC and be done with it!

Finally got my shit together and started this tonight.
Drilled out holes for pillars kindly supplyed by @shift14 and hogged out the cracks .

Devconed them in as a stage one.....this is just to locate the pillars inline with the action and once set I can remove the action(I hope[emoji23] ) then hog out clearances to bed the action in.

i guess if the action should "stick" you could always whittle the stock back off.
I reckon it will be ll good though
Lanocote for a release agent?
No just is on the bench from working with ss fasteners......tho I did look at it and think about it.Quote:

Mint :thumbsup:
The main problem with bedding a 75 is bedding agent forcing arund the sides of the front magazine catch. Put a layer of plasticene down each vertical side of the front magazine catch.
Is there anywhere other than the recoil lug you tape clearances stug?Quote:

Any vertical surface apart from the rear of the recoil lug should be taped, which is a bastard on a 75 because there are so many!
As @stug said, but even tape some of the horizontal surfaces as well. I double taped the bottom of the recoil lug, and the action around the magazine cutout. My only bedded horizontal surfaces are the pads/contact areas under the action screws, and the bottom metal.Quote:

I never intended to fully bed it just the front and rear areas to tidy up the bedding after ripping out stock material.
