The show at Harrogate gave me an opportunity to see one of these new fangled mandrel savers in the flesh
Obviously me being me my first thought was "how much" quickly followed by "I could make one of those" :nonono:
So tired of using a spanner to run a nut up the bolt that makes up my mandrel I decided to give it a go.
I had an old morse taper & a bearing retrieved from an old cordless drill the only problem was the one wouldn't fit the other, so the first job was to turn down the end of the morse taper to fit the baring.
Whilst on the Bridgeport a 1/4" hole was drill up the centre of the taper for the mandrel to pass through & the bearing friction push-fitted onto the morse taper.
After this a piece of Box wood was turned to a cylinder & a 30mm hole drilled in one end, this hole was then counter bored with a 20mm hole to prevent the centre surface of the bearing touching any wood & then a 1/4" hole drill through the centre of the blank
The Box wood was then held in pin jaws & the finished shape turned
Time to try it out!!!
Happy to say it worked a treat
The best thing about it is I no longer have to play "hunt the 11mm spanner" that little bugger was brilliant at hiding
