6mm collet chuck

[Dan Smith 2Participant @dansmith2]

Hi there, not quite a normal tool request..

Im looking for a 6mm collet chuck assembly idealy connected to a flexishaft that can be driven by a small drill or similar

this is actually to spin a 6mm eraser refill as a replacement for the old electric eraser machines that are impossible to find so ideally the collet would be fairly long to enable holding a decent length of the stick.

anyone got any ideas? or alternative solutioins?

where to find

Hi.

I cannot help with the collet chuck bit unless you manufacture one yourself, but could you use a Dremel or similar (some of the hobby store units are quite cheap). This would remove the need for the flex-shaft and seperate drill.

Best regards

Alan.

We have looked into using a dremel or similar but as yet we have not found one with a chuck capacity greater than 3.2mm when we need 6mm

6mm die grinder any good, high speed may be an issue

Can you get away with 1/4" collets? if so this and this standard head will do

I used to have a pencil extender , issued by the MOD. This was a thin tube with a split in it, a sliding ring was pushed down to lock. I know it would hold eraser rubbers because used it for that. I don't know if these are still sold ,but not difficult to make with a lathe.

Is this too much of a toy for what you are looking for?

I see Amazon has the staedtler one which would be more robust.

Remember throwing loads of teh old collets away when the art shop I used to work part time in closed down

[Chris SheltonParticipant @chrisshelton11794]

Could you use an ER11 collet chuck with a straight shank, and a 6mm collet.

They are available with a number of different shank lengths and diameters.

This is exactly the machine I am trying to replace, if you can find one that runs on 240v 50Hz and not 110V 60Hz it would be exactly what I need! unfortunatly I cant seem to find them anywhere in 240v

sadly yes,
mainly bacause we cant get the grey refils for one that rub out indian ink on draughting film, the only come with the white ones that rub out pencil only

Dan,

The 60Hz 'spec' should be no problem; just run it at 50Hz, and a small transformer is all you need for the voltage change. A 'Safety Isolating' Tansformer is nice to have … That's how I have seen them used.

There are Erickson double angle collet chucks available for die grinders. I have them in both 1/4 and 3/8 capacity. They have a 3/8-24 female thread for mounting. I know where to buy them in the US. I don't have a clue about availability in Europe.

Something like this.

Now there's someting, an electric rubbing out machine. Even many years ago when I worked on a drawing board we managed with ordinary erasers except when we had to alter drawings on linen, when we used a fibre glass PCB cleaning pen.

However, it can't be stunningly difficult to make something that will screw onto a Dremel nose and grip a 6mm diameter eraser (better not call it a rubber in case Uncle Sam is watching). My Dremel clone came with a flexi shaft if weigt is an issue.

[Dan Smith 2Participant @dansmith2]

I still work on linen drawings from time to time although the majority of the pre CAD drawings I end up altering are on some form of acetate (often Brown line prints)
We use standard rotring isograph pens to write on these and we need to be able to rub out old isograph ink and brown line lines

Fibreglass pcb cleaners do work but we are not allowed to use them any more in the office as they create sharp fibrous dust tat is a hazard if inhaled……

Was modifying a circuit on a pen on Brown line print today that still had the original signature from whoever drew it originally in 1969 still in place

Need to improve your QC if it takes 36 years to spot an error

A 6mm ER11 collet would work if you had a suitable spindle/holder for it.

[JasonBModerator @jasonb]

I think even a Dremel on its slowest speed will be too fast from what I remember of these erasors. You also really want a collet as chuck jaws dig into teh soft material and it soon breaks off.

..must be some interesting base number this math is using..…or the thread time-travelled..
