DIY Threaded insert (Helicoil)

[ncollar]

It is always amazing what can be made up when in a pinch. I experienced a similar deal and for some reason could not find my 7/16 20 die. I needed a sleeve to thread on a ball joint for my garden tractor. The machine was made with 1/2 20 male and female, but the parts house could only find the 1/2 for the rod end the other was 7/16 20 thread and I need to bring it up to .500. and about .300 thick. after several tries it worked. Love a challenge.

Hi Nelson,

Necessity is the mother of invention.

I guess that is the reason this is my favorite site. There are a lot of talent out there and people sharing freely.
That is the best thing.

Hi, Some quick help. I saw your video and made some inserts. Much easier than I thought. Need to put inserts into alluminiun motorcycle head. Will steel react with the alluminium at high heat. How do I "lock" the inserts into the head.

Thanks,
Peter.

Hi Peter,
You can use a thread sealing glue applicable for high temperatures
but I haven't tried it till now
it is only a thought on my mind.
But before proceed you need to confirm that the threads into aluminum head or at your insert it is correct.

I have used my DIY thread inserts to repair cracks in bolt holes of the blocks of antique engine blocks where the boss of the bolt hole would be in the water jacket.
How I did this was to drill and tap to a larger size mix a heat resistant epoxy, apply to the thread then screw the bolt into the hole cut it flush with the surface, drill my locking pin holes in between the edges of the threads drive in the locking pins allow it to completely cure then drill and tap to the appropriate thread size.
Each persons repair needed is going to be a different scenario. No 2 repairs will ever be just alike even when using off the shelf repair inserts

This is the most clever thing I've seen all day.
