I have the Metric version of the Precision Boring Jig which has Guide Bushes of 6, 9 and 12mm but I have a need for a 10mm Bush to finish off a commission.
I have contacted Robert Sorby and the best they could come up with is use a 3/8" or the 12mm, Urgh! quite how this helps for my requirement?
Does anyone know where I might obtain a 10mm Bush to suit this Jig.

Do you know anyone with a metal turning lathe that could make one for you

I do have that option but the Bushes are Hardened.

That is the only problem. How about buying THESE then make a carrier from other metal drilling a hole through the carrier so a longer screw can grip the guide bush. Hope that makes sense and also assuming the guides I linked to are hardened and of the correct size to allow for a carrier. |

I made a jig similar to the Sorby one out of a length of inch square aluminium bar which I turned to fit the banjo and drilled a hole to take the Axminster bushes. I tapped a 1/4 inch Whit thread [because I had a suitable 1/4 White thumb screw] down the axis of the system to hold the bush in place. MC |

As MC said shouldn't matter if its not hardened for limited use, but you could also use the 12mm bush with a 12mm x 1mm tube to pad the drill bit to the bush
