RobH Posted November 20, 2021 Report Share Posted November 20, 2021 (edited) Spherical turning attachment Bob. You rotate it with the handle seen sticking out to the right, so the cutter describes an arc. Ā Moving the toolpost along the slot changes the radius being cut.Ā I think the clue on what is being made, is in another thread on here from a couple of days back.....

Z320 Posted November 21, 2021 Report Share Posted November 21, 2021 Yesterday I watched a YouTube video about! Using it on the other side ofĀ the center you can cut a concaveĀ surface, and using this sidewards the bar you get a nice surface for a ārilledā handle for the handbrake lever!

Yes it is a RDG Tool. Ā Not wonderful but effective. Ā Biggest problem is getting the tool near to the standard chuck without impingement.Ā Ā I get round this with a smaller diameterĀ chuck. Setting diameters is not incredibly accurate.

BlueTR3A-5EKT Posted November 21, 2021 Report Share Posted November 21, 2021 Here we goā¦. A gear knob in stainless steel following the shape and sizeĀ of an original rubber one. Ā Knob is going to a forum member. Started with a 100 mm of 35 mm stainless bar. Ā Turned taper on one end comparing it with an originalĀ Drilled 10.3 mm for tapping Tapped 7/16x32 ME Parted off length as deep as dared. Fitted to threaded mandrel and spherical turnĀ end and blend as required. Clean up tooling marks with 280 wet and dry using suds as lubricant. Polish on the mop to remove scratches and get a lustre.

BlueTR3A-5EKT Posted November 21, 2021 Report Share Posted November 21, 2021 A full afternoonās work done over 3 days. Ā The most time consuming part was setting up the spherical turning tool to the required radius and then trialling it on some aluminium bar. Tapping took a while as it is done by hand turning the lathe spindle to get 1.25 ā depth. Ā 32 tpi x 1.25 = 40 full turns in 1/3 turn moves backing off every cut to clear the chips, plus dripping cutting lube in. Ā Ā Last thing I wanted was a broken tap!

Some of you many have seen my recent thread (linked below) enquiring about gearstick thread sizes, and the availability of a Moss Motors aluminium gear knob. In response, Peter W generously stepped forward and, going far and beyond the call of duty, offered to fabricate the glorious custom billet steel gear knob you see above.Ā Once again, exceptional thanks Peter! It isĀ far more than I couldāve hoped for. What would otherwise have been aĀ Moss Motors stocking filler, now upgraded to a hand-crafted original shifter, andĀ pride of place under the tree! Hugely appreciated. Cheers, Deggers Ā Quote Link to post Share on other sites

john.r.davies Posted November 22, 2021 Report Share Posted November 22, 2021 I don't know if they are the wrong size, but one of the well known TR2-3-4 hubcap badges would looks well on there. On the lathe, you could cut a recess on the topĀ of the knob for the round badge and epoxy it in. Quote Link to post Share on other sites
