As per my “what did you with your bike” I have sourced some replacement Rivnuts, now I’ve seen some hacks for fitting them without the tool, anybody have a sure fire method that’s worked for them? Otherwise I’ll have a look at YouTube tonight

Disclaimer, haven't tried this, but would think that the appropriate bolt, nut and washer combo could work.
Thread nut onto bolt, add washer, thread rivnut onto the end of the bolt..
Insert into hole, hold bolt head with spanner, and "loosen" nut with another spanner (i.e. try to undo the nut off the bolt).
Maybe a little grease on the bolt would help too.

I've done this with Rivnuts/Nutserts (same thing, different names) to tighten them when they haven't initially been crimped tight enough. It works. :)

I've done this too, with mixed success. A couple of times the bolt sheared under pressure. Other times I got a nice clean crimp. I wonder if the proper tools must use a hi tensile steel or something in the bit?

Sounds like a hi-tensile bolt is required. A few cents from your local not and bolt supplier (don't go to Bunnings)
 
Why bodge it when you can just drop $300 on one of these ratcheting badboys?
Even comes with a swanky case so everyone knows you’re a wanker.

Well it worked, I bodged the first one then second one took a little longer and keeping tension seems to be the key, @Ultra Lord I did think about buying a cheapie, found a couple for $30 but I decided against it.

Hack - if you doing with a bolt, washer and nut method, I worked out to get a nice rounded edge on skinny seat tube, put a brake or coned washer against the rivnut, mind you I worked this out while trying to get it a little tighter but it seemed to work.

If you’re not doing many 100% just ram that shit home with some washers and a lubed bolt.

I hundreds in. I had the lever arms but they struggle with anything bigger M8 stainless, they break, and they’re bulkier than the bougie one I bought.

Had a job that needed 68 M12 stainless rivnuts so I bit the bullet and have zero regrets. Had all those bastards drilled and fitted in an hour with this bad boy.

It’s nothing fancy (don’t zoom in too hard) but it’s working and will get a lick of paint this weekend to match the others (they all got painted during the frames colour change).
The first washer I had was a little too thin and did burr and damage the face a little, that’s when I swapped it out for the cone washer, a couple of nice M5 mudguard washers I think would work well if you want a nice flat finish plus protect the frame or the cone washer for the curved look.

The guy who was supposed to be training me picked one of these up the week I started. They gave him the arse the next week and it mysteriously disappeared....... 🤔

Yup. Some guys just want to watch the world burn.
We lost our 1m verniers the same way.

They where really handy for trimming pump impellers and measuring gasket diameters without busting out some string and a calculator. Not to mention the loss in accuracy.
Yes I’m aware circumference tape exists but then I have to order one and those verniers were just so damn cool to wield it’ll never be the same.

That and I Spent all my moneys on rivnut ratchets and replacing a fluke clamp meter. Bloody tools eating into my bike funds.
 
One of my mates needed a cheap ultrasonic to clean up an old carby. They didn't want to pay ultrasonic money, so bought a $20 orbital sander and went full-bodge on it... 😂
