ER Collet Block Depth Stop

[@ronwilken5219]

Hi Matty, I haven't looked at other comments so someone else might have made the same suggestions. On getting the tapered fingers to spread easier, make the taper only about 10 mm long (deep) and then bore it out behind. You did some but maybe not enough. Also cut another four slots, total eight. On the "drawbar" part, cut the taper only for about 5 mm and cut clearance behind. That way the "fingers won't be so stiff and the tapers are only working against one another over a maximum of 5 mm. At the moment you're working them over about 15 mm though you did undercut them behind a bit but still lots of drag. Otherwise a pretty good idea. Might just try one for my ER 25 ones. As big as I go at present. Already have a couple for the 5 C collets. Thanks for the video, stuffups and all. Regards from "upover" in Canada's banana belt.🤞🇨🇦🍌🥋🇺🇦🕊️🇦🇺🐨💩💥🏁👍

[@MattysWorkshop]

Gday, I’ll definitely be putting more slot in the taper which will improve it quite a bit, I like to show the screw ups in the videos, it’s what happens here, appreciate you watching, cheers

[@thepagan5432]

Whenever I made a slight hic-cup on a piece of a jig or tooling for in-house use, it would become a prototype or proof of concept piece, if it worked it was fine. If you ever meet an engineer who claims never to have made a mistake, they are speaking with forked tongue. Good job Matty, stay safe and well, regards to all 👍

[@MattysWorkshop]

Gday, it does work but with a little modification it’ll be much better, appreciate you watching mate, cheers

[@paulcooper9135]

Nice build! Taper ... it's the only thing I might have done different ... 8° (16 included) would have been my choice .. that's the standard for er32 collets and some engineer WAY smarter than me figured out it works best for such applications. Thanks for sharing 🇨🇦

[@MattysWorkshop]

Gday, I should’ve went with a different taper and I’ll be putting in more slots to, appreciate you watching, cheers

[@joeybobbie1]

Hi Matty, I think it turned out Great. You sure do some nice work, and you make it look so easy. I always enjoy watching you do Machine work. Thanks for the Videos and Ideas.😁👍👍

[@MattysWorkshop]

Thanks mate, appreciate you watching, cheers

[@Rustinox]

As I can see, you use printer parts too. They are very nice pieces of steel. Nice little build, Matty. And I share the same idea that I read in the comments. Double the number os slots in the taper and it will work just fine.

[@MattysWorkshop]

Gday Rustinox, ill definitely be putting in more slots, that was a screw up there but easily fixed, the rods out of printers are pretty good material, thanks for watching, cheers

@@MattysWorkshop Mate, its a useful skill to have. You seem to do it because you enjoy it, rather than doing it for the sake of it👍 One of the reasons I enjoy your channel.👌

[@samrodian919]

Nice job Matty! Yes I thought you were being very hopeful at single pointing the 8mm thread that long, but you did it mate. I though to myself "You jammy bastard," when it threaded on with no drama lol it clearly was a quality piece of steel with the right amount of toughness to resist the cutting forces of the tool. All in all mate it turned out very well. You are a much better machinist than you give yourself credit for. I think I might give one of those a whirl, the only thing I think I would do differently is to reduce the angle to around 6 degrees included instead of 10. It should make the deflection a bit easier and enable it to be done by hand. I will also do 45 degree slots to double the "petals" that expand. That should make it easier to expand it by hand. I hope you are feeling better after your treatment Matty and things are going well for you. Cheers from the UK. Sam

[@MattysWorkshop]

Gday Sam, thanks for your kind words, I have to put more slots in and that should fix that issue, the rod machined really nicely and bugger all deflection, appreciate you watching, cheers

[@garyc5483]

Great job Matty. Looks a treat. Put 8 slots in the taper and it will nip up much easier. The 1/4 of a circle does not like to move whereas an 1/8 will. Printers are a good source of all kind of parts. ATB regards from the UK

[@MattysWorkshop]

Gday, I’m definitely going to cut more slots in the taper, I did screw up there mate, the rods that come out of printers is pretty handy material, thanks for watching, cheers

[@markneedham752]

Hey Matty. Flash job mate. The internal female expanding bit, I cut a groove also.. but on the outside, end of the slots near the shoulder., also cut 3 slots., ie 6 segments..! You'd be surprised how much movement the collet makes,.. even Hand Tightened. ... and, for the male expandy bit, I used a 12mm bolt, and booker rod/all thread for "The Adjustable Stop." Amazing watching you do and explain it, how much work there is in it.

[@MattysWorkshop]

Gday Mark, thanks for the idea, I did screw up there and will be putting more slots in the taper, appreciate you watching mate, cheers

[@johnjewell219]

Hi matty hope your treatment is going well ,you’re looking good . Looks like a good project as I have a set of those collet blocks I bought for my retirement projects if I ever get time between doctors appointments and favours for friends,lol all the best John😎🐈‍⬛🇦🇺

Well made, Matty. Very useful bit of kit.....Tony

[@MattysWorkshop]

[@stillraven9415]

You need more slots in it. Each piece goes 1/4 of the way around so they don't want to flex

[@MattysWorkshop]

Thats exactly what it needs 100%, thanks for watching, Cheers

[@tiredoldmechanic1791]

My thoughts exactly, 8 or even 16 segments would work. There shouldn't be much force on it. The collet holds the work in place. Pretty easy to make a couple more cuts.

[@joedowling5452]

Well done Matty. You seem to have this seat of the pants engineering thing down to a science.

[@D40..]

Gday Kev, It seems a lot of my projects are made up as I go, Appreciate you watching mate, Cheers

[@bobvines00]

Matty, I was going to recommend that you cut more slots in the female taper, but I see that several others have already done so. If your coffee-colored coolant smells bad, look into getting an anti-bacterial additive for your coolant to kill the oil-eating bacteria. If you've got oil floating on top of your coolant in the sump, maybe get an oil skimmer to minimize the amount of "food" you're providing to the bugs. You might also consider adding a filter to your coolant system. If your sump is full of crud, you'll want to clean it out before adding new coolant to it so that you don't immediately contaminate the new coolant.

[@MattysWorkshop]

Gday, the coolant doesn’t smell, I do have a skimmer but I’ve been lazy, it’s over due to be changed that’s for sure, thanks for watching, cheers

Hi Matty, a great idea! I would suggest additional relief cuts every 45 degrees to ease the expansion of the taper. This will also work as a lathe spindle stop.

[@incubatork]

Worked out fine in the end, I would have thought a shorter taper on the inside part would work better, as is you are trying to flex the whole length of the cut-out, all it needs is a small part of the tip to flex out in order to grip and spread, probably 10 - 15mm would be plenty taper on the plug, this will make it easier to tighten by hand too.

Thanks for the great content and keep healthy. Greg Tutin Launceston TAS

[@MattysWorkshop]

Gday Greg, my lathe is a Hare and Forbes AL960b, it's the smallest Taiwanese lathe they sell, its done everything ive asked from it but im starting to think its possibly time to go a bit bigger when funds are available, The mill I have is a Cincinnati 2L, its a horizontal mill with a vertical universal head, its a great solid mill but not a lot of Z height, hopefully ill be upgrading this soonish with a bit of luck, Hope this helps mate and appreciate you watching ,Cheers

[@ianmoone2359]

The AL1000D is 3 phase, Taiwanese & has a foot brake that you wanted Matty. They are around the $12.6k new from Hairy Forbes. Spindle diameter is only 40mm tho. They are a 14”x40” swing & between centres. Been selling them the last ~20 years or so. Theres a 2008 built one in reasonable nick near me for sale used in WA asking $8.5k that has 3 chucks and other tooling with it. Old German guy bought it when he was aged 80 & just turned 96 & can’t use it any longer so it’s available. Bit dear to ship it West to East or worse Tassy tho.

Nice build Matty. A thought on the taper....what if the male and female sides were a half degree off so they first engage as an interference then spread out to match? I too think there needs to be more cuts to have thinner sections.

Hi Matty. Do you think that reducing the length of the external taper to something like 5 or 6mm so that you are only trying to deflect the tips of the slotted section would make it more sensitive.
