rosco01 Posted May 3, 2020 Report Share Posted May 3, 2020 Terry, just in case you want to purchase a second one as spare.... I used the grub screws from the Slot-It wheels for my home made wheels.... I found that the thread for these is an "M2" fine thread.... 2.0 mm. I don't believe (might be wrong) that M2 comes in any variation in thread.. I think they are all this one fine thread..... unlike other thread codes.... Metric, as I have read thus far - come in fine or coarse.... I am not aware of an M2 in coarse. I use a pin vice for tapping these small threads... the tapping drill I used was 1.6 mm.... after first using a 1.0 mm drill - then reaming out that hole with the 1.6. I took small bites with the tapping tool... 1 turn in... then back out... repeated many times. I have found this to be a good way of getting a very clean thread..... I also use a cutting fluid called "Tefolex"... a tub of that stuff will see your grand-kids out... but don't use it in a powered drill... it can give off very nasty fumes if it gets hot.... Hope this helped... frats, Rosco Quote Link to comment Share on other sites More sharing options...
Terry Posted May 3, 2020 Author Report Share Posted May 3, 2020 Thanks Rosko, I will take those very helpful tips,in the past I did, as you said , take it very slowly,but I wasn't aware of the Tefolex which I will get. Thanks again Terry Quote Link to comment Share on other sites More sharing options...
charlesx Posted May 3, 2020 Report Share Posted May 3, 2020 (edited) Hi Terry. Probably too late now but I think SlotsNZ/Mark Burgess has M2 taps or he used to. Regards Chas Le Breton (charlesx) Edited May 3, 2020 by charlesx Quote Link to comment Share on other sites More sharing options...
Vinno Posted May 3, 2020 Report Share Posted May 3, 2020 I think it’s better to leave this open, tips are helpful. Quote Link to comment Share on other sites More sharing options...
Kevan Posted May 3, 2020 Report Share Posted May 3, 2020 (edited) M2 x 0.4 is what I used to do the very same job yesterday. It's classed as a coarse thread in my Zeus book. ...and I used a drop of 3in1 oil for tapping the 1.6mm hole. Edited May 3, 2020 by Kevan Quote Life is like a box of Slot cars...
