Diy Brushless Spindle

I was having a look to see if there was anything out there like a pin vice

You might be able to do something like drill and ream/bore a 1/8" hole and hold the cutter in with a grubscrw. The force on the cutter will be very small, so it should hold perfectly well.

I was having a look to see if there was anything out there like a pin vice that could be used but thought I'd float the question.

I've scoured the earth looking for a good quality pin vice type thing... it drove me up the wall... i even did a search for ER3 collets lol ... alas... there is no such thing :(
I considered making my own but that is now on my "things to do in the next life list"

give us a shout if you find anything "posh"
i'm pretty sure it would cost a bomb if you find anything of quality out there
its a dam shame

Looks like ER8 is the smallest:

The thing to do is have a go at making your own ER8 or ER11 collet chuck.

going down the DIY laser route today. Could make a real lightweight router then ;)

I'd love to see a router made with a laser...

I'm rapidly coming to the same conclusion Mark...there are pin vices out there that could be used but as Jonathan says...runout! Saying that for my balsa needs I could live with 0.25mm.

Might have a look at making my own collet chuck to take the Proxxon collets...but there again I might just as well use my Proxxon :)

ahhh, yes... but will it run at 48000rpm :)

[njhussey]

Erm....no 20,000 is it's limit. What you running a 4000kV motor??!!

eerm, yea its 4000kv but I tend not to run it passed 20000rpm if I'm honest... it might be fine flat out but I don't like it :)
iv got tons of spare bearings so I should go for glory and the fun of science and run it till it grinds to a halt but I never do

air blast cooler

sounds posh ?
what is it ?

[njhussey]

On my next spindle I'm going to cut the housing in layers (done on the Router) and have some water cooling to keep things cool. Looking at work to see what the smallest air blast cooler I can get is...

I've got lots of bearings too, comes from having lots as spares for the RC helis ;)
