|Thread: Parting off alluminium|
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.
|Thread: spur gears for 2017|
Happy new year and best worksop wishes with spur gears for 2017.
|Thread: Wimberley lathe tool holder|
Look at my article "an HSS tooltip holder" in MEW N°239 issue (march 2016).
|Thread: Ball bearings for 2016|
Happy new year with ball bearings for 2016
|Thread: Tumble deburring|
Look at the article: "The rumbling tumbler" in the Nov/Dec 1994 issue of MEW.
|Thread: Cylinder Honing Tool|
You'll soon dicover that honing is boring, so why not try boring instead of?
|Thread: WOW moments|
I had seen a wonderful rainbow in Geneva, the end of the rainbow was in bank! certainly there was a pot of gold there but unfortunately I had'nt any access to the safe and haven't seen it, sorry.
|Thread: New Free Plan - Jeclanide Handwheel|
Look at my video on Youtube: **LINK**
|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: milling cutters for 2015|
Happy new year with milling cutters for 2015
|Thread: polishing spindle taper threads|
Look at this video:http://www.youtube.com/watch?v=I57FCsvUajg
|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: Taps and dies for the new year.|
|Thread: screw cutting made easy|
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'|
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.
|Thread: screw cutting made easy|
A near relative of the "Snap-tap" attachment has been descrtbed in "Model Engineer" (no photo, only sketches). Try to find in which issue!
New video showing the home made attachment at work : **LINK**
