I've contrived an attachment which solves the problem of tool jamming, just wait for some monthes as this attachment will be described in MEW.

Thread: Do all bevel gears of the same MOD mesh?

you must buy the gear pair as the angle between the gears axis is involved.

Hello

You'll soon dicover that honing is boring, so why not try boring instead of?

Thread: identifying brass from bronze

I think the best way is to measure the density: weight the piece, put it in a graduated bowl half filled with water to know the volume, divide the weight by the volume, compare the result with the one for a brass sample. Brass density is lower than bronze one as brass is usually copper with about 40% zinc while bronze is copper with about 10% tin, zinc and tin having almost the same density.

Thread: Identifying brass from bronze

Find the density (weight devided by volume), brass has the lower density because brass contains about 30 to 40% zinc and bronze about 10% tin, zinc and tin having almost the same density.

Thread: screw cutting made easy
02/11/2013 09:04:24

You'll find a near relative of the snap tap in ME issue N°4177 (sept 2002) title: A high speed thread striking attachment. The problem is : what happens if the feeding force is more than the spring one?

 The problem with this tool (15° rake angle) is that it must be of the spring type for the tool not to plunge in the work as the chip is very wide for the last cuts.

Thread: Ted McDuffie's 'Variable Lead Threading Attachment'
24/10/2013 10:17:48

I've made a taper turning attachment "all contained in a tooholder"; making a morse taper with it is almost as easy as making a cylinder (very quick set up). you'll know it as soon as some magazine would want to publish it. Don't be too optimistic as I've 7 (seven!) articles waiting in ME or MEW stock since 2006 with no publication, why should I write a new one.

A near relative of the "Snap-tap" attachment has been descrtbed in "Model Engineer" (no photo, only sketches). Try to find in which issue!
