Rounded Torx chipper bolts !!

[treediver]

Ive just stripped one of the torx bolts while changing my chipper blades on my timberwolf ..DOH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Managed to slip off the bolt and eventually totally round off the inner.

Any ideas how to remove it as its totally rounded.

If you have a welder you can weld a nut to the head of the bolt and use that to remove the bolt.

you need one of those impact drivers if you've done what i think you mean

[Mr Ed]

Impact driver is the only way, short of drilliing the head off the bolt.

Edit-

Not sure what people do with their TW's, but on my Farmi's I used to run, I used to replace the bolts every time the knives came out, as they were silly little bolts.

It's a case of clean the socket out as much as possible before trying to undo them, replace if damaged, and coat the threads with copper grease before refitting. The sockets get damaged if the tool slips out when you're putting torque on, and it's downhill from there. I bought an air impact wrench, and find there's a lot less chance of slipping.

also you can try an allen key that you can hammer into the head to make a new drive surface

i clean all the crap out of the heads of the bolts on my tw using a dentists tooth scraper thing £1 from a carboot. it works really well.

managed to get the bloody thing out after making a groove in the head (really arkward bastard job), heating it up with a blowlamp and then whacking it constantly all evening until started to move round...and thank f@ck it did! eventually..

Yes a hammer impact driver will quickly pay for itself on that sort of job, greatly reducing the time it takes to get the job done.

The shock loading from hitting the end of the tool helps to loosen the bolt in the threads and undo it. Also much less likely to round off the star.

On our grinders, when a bolt on a tooth get's buggered, we use a torch to melt the head of the bolt off, takes all of 3-5 minutes, the tooth is shot afterwards.

 

Welding a nut/bolt/tool on the head also works.
