Hello Alan Need to make one of these as well. Always wondered about that Taper. Need to read and check up on that, a little more. However, seeing U doing this makes it so much easier, simpler and all the more possible. What we feared was only our own ignorance !! Will "get 'er done" - like The Man Says !!! Thanks for showing and sharing ATB aRM

Thorough and helpful video. Thank you!

Thanks for the vid! The trick with lining up the threading bit along side the chuck jaw was worth the price of admission so to speak!:) Have fun, G.

Great video. I like the pace of it.

Thank you for that video it's exactly what I need (and I have almost all tools available)

Me inspiraste en hacer mi propio collet holder. Gran persona, saludos.

Muchas gracias por los videos. Muy claros. Enseñan mucho. Desde Argentina

For reduction of run-out of bar, use 4-jaw chuck with dial gauge. It was obvious from your cut that the bar was way out of true.

lovely job here's my 2p's worth grind your parting off tool the other hand so the leading edge is tapered towards the left (tailstock) so the part that you part off doesn't have a bur left on it this comes in very handy if your making shims which are hard to debur

The more You have the micrometer blue, the better match You get with the taper 😁 With known tapers I always use my 100 millimetre sine bar.

Thank you, it was to watch. Would be interested in seing you grind some bits with that grinder

Hi Davis go to kzread.info/dash/bejne/a6us0Nmwf926mJM.html

Brilliant

Thinking about it having worked on fitting an ER40, when you were talking about not pushing the collett too hard otherwise it would spring out of shape may I suggest inserting a very accurate bar or expanding arbor so that it retains the correct angle. Cheers

Hi Ross Yes you could use a small length of silver steel.

Very helpful video sir .

Well done sir

Allan, I had really hoped that you would show how to make a collet nut with a bearing surface. Love your grinding platform.

Hi Gordon I did look at making a collet nut but I haven't got the equipment to grind the internal taper

I made a collet chuck once. Used it a few times and the inside got damaged considerably by the hardened collets. In other words. You need to harden your work piece.

Not sure why you had damage. If all fits together as it should, there is no movement to cause damage. I have made my own ER32 holders in round, square and hex mild steel and have no detectable wear, let alone damage. Check your fit and taper, and no need to over tighten. 25 FT pounds max.

Второе замечание - такие детали чтобы не было биений надо точить за один проход, не переставляя заготовку. Интересно было бы зажать этот патрон в токарном патроне и померить индикатором биения, что-то мне подсказывает что они будут и не маленькие. Хотя для тех целей что показано на видео - заточка инструмента, можно было и сверлильный патрон применить ;)

Ну он может руку набивает, хотя в общем правльно приметил, цанги это прежде всего точность, все часовые станки на цангах работают, а тут перестановки, с резьбами не понятно. Но в отличии от патрона они будут удерживать намного лучше.. хотя тоже сомнения для данного варианта, а надо ли это..

Great project with a great result. Your cutter grinder has a brilliant alignment table. What make is it?

Hi The cutter grinder is a kit from hemingwaykits.com. See my video making a tool and cutter grinder It shows what you get in the kit. kzread.info/dash/bejne/h6qpxKufnbrHedo.html

Thank you Alan. Such a fabulous kit. I will certainly look into this as well as your video. I currently have a Taylor Hobson cutter grinder that is in need of tlc. I need to weigh up whether to spend time and money fixing the Taylor Hobson or perhaps go for a Hemingway kit. Thank you for the inspiration. I am a total novice, loads of enthusiasm. Now to put that into practice.

nice

Made a whole set out of titanium for one of my lathes

Странно что автор не сделал ни захода ни схода для резьбы. На стандартном патроне они есть... А так познавательно, хотя я не понял как точно выставили угол для точения внутреннего конуса?
