Following the advice from Gary I decided to buy some Hegner quick clamps for my new axmister scroll saw, but being impatient (and tight 
) I decided to have a go at making some :shock:
First attempt was just a 4mm cap head bolt braised onto a wing-nut it did work but you needed a pair of pliers to tighten the clamp enough which defeated the idea
Second attempt was a small piece of 4mm treaded bar heated by blow torch and bent at 90 degrees then fitted into an old plastic thumbturn with the help from Mr Dremel Tool. Total disaster I overheated the bar for a start and then tried to bend it to tight (as you can see it cracked) and the plastic thumbturn was too weak.
MK3 was made with a longer bar heated less and then fitted with two nuts. A bit basic but it worked
A bit of 'tarting up' ; cut to size and finished with some air tube from the aquarium pump and hey presto
Here it is fitted to my new toy. The idea of the two nuts is so I can adjust were the bar points when it is tightened.
I have been using it all morning and no probs yet.
You wouldn't think you could get so much pleasure out of saving £13.90 :wink:
