I am getting close to finishing my rebuild project and am now clearing up the smaller items. However the mag compass is 'Stuck on 100*' regardless of the aircraft heading although when removed it is fine.

The bracket in which it is mounted is clamped to the main spar carry through tube, and was for some 50 years prior to being repaired by splicing in a new section. I have come to the conclusion that the welded section was not demagnetized.

My thoughts on a fix are obviously to demagnetize but how?

Any thoughts on the way ahead or where I could hire a suitable hand held demagnetizer would be very welcome as I am not going to get 'signed off' until the compass at least gives an approximate indication of the way I am going.

Many thanks
