Tikka T3 GRS Laminate bedding

Tikka Masala

First of all what an awesome site! Nathan has been so helpful via email and I've decided to make a thread to chronicle my first bedding job.

Partly I've decided to make this thread because I couldn't find specific enough information searching online, and even reading the existing thread on this forum.

Nathan's videos have been very helpful for me to get my head around the overall concept but I figured I could get a few pointers as I go and this could eventually be a very specific step-by-step with pictures on how to bed a T3 into a laminate stock.

Rifle is a T3 lite 7mm RemMag
Stock is a GRS adjustable hunter
Bedding compound is MatchGrade bedding compound

Re: Tikka T3 GRS Laminate bedding
Now, I plan on keeping a record of all steps I take with this bedding and for better or worse will have pictures at every stage...as long as I can have hands free. If it doesn't end well I will re-do the job, the compound etc only took 24hr to arrive when I ordered so it's not a big deal if I have to order again....but not my first choice!!

I'm hoping this thread an end up as almost a step-by-step.

Bearing in mind that I've set aside at least 2 weeks to get this done, and get it done right. I'm absolutely not in a hurry. In my experience being methodical and taking things slowly and thoughtfully will end in a better result. Please, nobody feel obliged to answer all of my questions in one go, and if you do answer any of my questions don't feel like you have to write an essay. I'm happy to wait either way.

My first questions so far:

1.) Masking tape, electrical tape, aluminium tape, powdered graphite. What brand/type (if it matters)? Where can I buy it?

2.) When I draw around the shape of the action in pencil I then move in a few mm at the tang and draw another line so there will be a reference level left after I've done some dremeling. Will the tang rest on this point at the back when I'm easing the action down into the compound, or is it just a visual reference so I know how much material I've removed during preparation...and this itself gets removed at the end?

3.) In the video the Remington had the bedding to support the barrel because it was a bit of a beast, does the T3 barrel also need this? How far forward of the action should I bed?

4.) Is the front of the action supported by the dam up by the barrel, and the rear supported by the reference point I left when removing material around the tang?

5.) The parallel walls of the stock next to the action and very very very close to the action. I need to remove the same 1.5mm+ on each side as I will below the action right?

6.) In the recoil lug recess I need to remove enough material so there is approx 4mm of space for compound on all sides? This will give the compound enough strength and prevent me bumping the lug as I'm easing the action into the mortice. Is this correct?

Re: Tikka T3 GRS Laminate bedding
Ok, for starters, you need to be absolutely sure you want to show this. You have set the bar very high for yourself by putting your first job online. Sometimes it is better to keep working privately with me and allow yourself to make mistakes without the pressure of a show and tell. Also, I plan on making videos for Tikka users later this year.

As for your questions.

1.) Masking tape, electrical tape, aluminium tape, powdered graphite. What brand/type (if it matters)? Where can I buy it?

Hardware stores- engineers supplies being the best. You may need to purchase graphite from a reloading shop (sold as neck sizing lube).

2.) When I draw around the shape of the action in pencil I then move in a few mm at the tang and draw another line so there will be a reference level left after I've done some dremeling. Will the tang rest on this point at the back when I'm easing the action down into the compound, or is it just a visual reference so I know how much material I've removed during preparation...and this itself gets removed at the end?

The action will rest on this. Yes, it is your height ref point.

3.) In the video the Remington had the bedding to support the barrel because it was a bit of a beast, does the T3 barrel also need this? How far forward of the action should I bed?

Yes, the Tikka can utilize this as a harmonic dampener for this whippy barrel, yours especially. This also acts as a major reinforce for the plastic stocked Tikkas. Bed 1 to 1.5" into the barrel channel.

4.) Is the front of the action supported by the dam up by the barrel, and the rear supported by the reference point I left when removing material around the tang?

Yes. If the stock was plastic, you could also use the pressure point ribs in the barrel channel as height ref points. But in either case, the front dam is critical for height.

5.) The parallel walls of the stock next to the action and very very very close to the action. I need to remove the same 1.5mm+ on each side as I will below the action right?

Yes. I prefer to use a heavy coating of release agent. Another forum member Marty prefers to use electrical tape on these parallel walls for good measure. He has blogged this bedding in the Tikka bedding thread.

6.) In the recoil lug recess I need to remove enough material so there is approx 4mm of space for compound on all sides? This will give the compound enough strength and prevent me bumping the lug as I'm easing the action into the mortice. Is this correct?

Yes, remove as much as you can without compromising stock strength (also remove material underneath) for the exact reasons you mention.

Yes a big call indeed....

I don't list my complete bedding jobs step by step as l only wanted to offer a few pointers or tips & stir Ideas in people, If he can l can type thing.
Nathan & Steph make an income from selling kits and helping people through this challenging (but rewarding) process so l leave it up to them.
If Nathan posts a Tikka how to video then great.

Yes, l have taped the sidewalls as I taping is the easiest option to begin with (& advised by Nathan at the time) but......... l will be using release agent as Nathan does in the next Tikka I do. This may help with the torque through the action on bigger cals but that's just a thought!
I have 2 point bedded these without tape with great success.

Your questions are answered in the rifle book so have another read through and away you'll go.

Re: Tikka T3 GRS Laminate bedding
Thanks Nathan and Martin

The more I think about it the more I think it might be smart to help by showing the exact materials I use, get a bunch of nice pictures as I go, and hopefully be able to show a nicely completed job at the end. For me it's enough pressure to avoid messing up my stock!

I'll post back with the bits and pieces I get together.

Re: Tikka T3 GRS Laminate bedding
Graphite powder from repco, aluminium tape from bunnings, other stuff from anywhere.

Now just need a squared-off knife, some old inner-tubes, some suitable thread-stock, some glue to temporarily secure recoil lug, and to find a nice soft makeup brush.

What glue is ok for the recoil lug? Should it be an epoxy instead of a CA, and only 1 drop will do it right! right?

Next post will be in 10 days or so. Hopefully curing!

Re: Tikka T3 GRS Laminate bedding
Just a small drop of super glue on top of the tape is the go to hold the recoil lug during fit up. The glue is viscous enough to migrate where it needs to go and not ruin your contact patch or clearances.

If you can get it, go with Nitto brand electrical tape (should be pretty easy, say Burson or Repco, etc). Great adhesion and flexible to work with, the best l have found having tried many brands.

Re: Tikka T3 GRS Laminate bedding
Thanks Martin.

Today I got:
Nitto tape from Jaycar $3.50
M6 threaded rod (1m) $1.70

Just need the brush and the glue. So just a drop of superglue will do the trick?
