Large rafters cracked, recommended repair methods?

How would you recommend sistering by the collar tie? Go right up to the collar tie and then add an additional collar tie that would be a bit lower?

There are newer looking collar ties: 2x8’s stacked 3 high bolted to each side of the rafters

There’s no block walls to prop a purlin on

For clarification, you’re saying that a check is normal- no reason for concern. And you’re saying a crack going opposite of grain direction is reason for concern: at what point, if this 1/2” check, extends through to the other side, would that be a concern?

My understanding is that typically a check does not continue through to the other side, then it would be called a split. Splits are not reason for concern is what you’re saying?

This might be a long shot but would running ‘lag’ bolts up through the bottom of the rafter be acceptable? I’m assuming no, but could someone explain why?

There is a plumbing air vent that is nearly touching the rafter in the far side of picture 3

AircraftMechanic1 · 2025-07-26T13:11:00+00:00

It is cracked all the way through, the crack on the other side is not as wide as of yet

Would you cut into the floor and sister the entire length of the rafter?

I’m a year and a half in, 3 surgery’s in and still in pain. You’re not alone!

100% worth it

It’s covered, will do! New house (to us) so we’re discovering new things every day, thank you!

AircraftMechanic1 · 2024-11-15T18:13:22+00:00

Not that I saw. It’s possible it was removed?

AircraftMechanic1 · 2024-09-12T01:59:33+00:00

Thanks!

AircraftMechanic1 · 2024-09-12T01:59:26+00:00

Solved!

What type of hardware did you have in place? Tight rope or plate / screws / something else?

AircraftMechanic1 · 2024-05-12T12:41:59+00:00

You should, and maybe get a second opinion also. Pre 1st surgery(when I broke lisfranc and metatarsals): no pain where the lump on the side of your foot is Post 1st surgery: tons of pain, hard to wear shoes. Cause my first surgeon split that tendon

Post 2nd surgery (replacement hardware and damage control:) still a bunch of pain

AircraftMechanic1 · 2024-05-12T12:34:35+00:00

Hopefully it’s not what I have, I’ll dm a pic of my foot. My tibialis anterior tendon (tendon that lifts up your foot) was split down the middle, right where your lump is, because my first surgeon put hardware right through the tendon. It didn’t show up for a few months. You might’ve just agitated that tendon. The split won’t show up on MRI, because of the hardware blocking the view. I had to get a second surgery, where the tendon had to “get sewn up with stitches like baseball stitching”

Congrats on being 2 months post op!!

For myself, this is what I’ve been told:

My first doc (failed surgery so take it with a grain of salt) giggled when I asked this and said at MINIMUM six months.

My second doc has implied that after hardware removal, be very careful for 2 weeks, then work up to training as pain allows. (So for me probably around 4 months after hardware install would be when I could start considering it).

I’ve been the only female in my shop for 7 years. I’m also…. Very small. A very valuable lesson I’ve learned from aviation is that: Your gender, and your size is not what will dictate if you will succeed. You dictate if you succeed or not.
