I have a thread going on about removing coilovers.

I nut shell I'm forced to hacksaw out the top mounting bolt.

Anyone got any suggestions on a suitable power hacksaw

Go Dremel or something similar from machine mart. Very useful for getting into awkward areas

Have you got a compressor? If so machine mart air hacksaw, small enough to get into tight areas and not heavy air consumption??

Nice idea thanks, but Dremel isn't much use, too small, not enough power, and cut depth is too shallow and orientation of the cut to the driven wheel means access is also compromised.

I have one and the biggest cutting wheel is still too small and can't get in there, even if I could get a bigger wheel the Dremel is too long to get in there.

Here is the issue, access is cramped.

Good tip cheers, don't have a compressor but I could buy/hire one.

I'll do some searching or do you know the part number/description ?

4" Grinder with a 1mm cutting wheel??

Or a nut splitter.

Or a hacksaw blade with a rag around it, some stout gloves and elbow grease.

I once used this to cut a cavalier SRI door hinge off to re-weld when a replacement door wouldn't quite fit. Good bit of kit if you have a compressor.

Like the ideas, I'm open to anything at the moment.

4" Grinder won't get in there, got one tried it.

Nut splitter not really much use, the nut comes off easily, its the bolt that is seized in situ.

Elbow greased hack saw would take too long as you cant get any downward cutting pressure due to poor access.

Now that looks promising.......I can hire in a compressor, I'll go see machine mart.
looks like it should fit in the confined space, just hope the blades are upto cutting through the bolt and sleeve.

If the work piece is rigid, i.e. doesn't vibrate, then a Fein Multimaster with appropriate blade would probably do the job well. There are also other types on the market from Bosch and the like.

I use one for work and it's a fantastic bit of kit.

Hi Adrian,

I hadn't thought of one of those.

Do you think it would cut through steel suspension bolts, about 15mm diameter.

Which attachment would do that ?

I've done that job and the tool you need is as already offered the 4" angle grinder. You may need to remove the guard.

The air recip saw is not powerful enough.
The vibrating multitools do not have hard enough blades bearing in mind the bolt will be high tensile.
A Sabre saw is the only other possibility using a bi-metal blade.

Steve

ETA. You don't need to cut all the way through in one hit. Make your first cut then rotate the bolt.

This, a reciprocating saw with a fine blade would be perfect.

Two very good points Steve, guard off and rotate the bolt, that should do it, I'll give this a go first.

I guess you've had the same problem to deal with then.

Looking forward to getting fronts in the air to see what chalenges they present me with.

Lots of heat. That usually does the trick.

just a tad worried about so much heat in a confined space within an inch of a very flammable body panel
