ER11 Adapter for the CT

[mtylerfl]

There are no bugs and no modifications are required...

Hi Dan,

Are there modifications required to the CT to get the ER11 installed for use? For some reason I thought there were, but maybe it just slides into the CT chuck (like an adaptor?). Sheesh, I can't remember.

I bought one on bergerud's recommendation. I now have two of these. Thinking of a third, it makes using smaller bits so convenient.

Thank you bergerud!

The ER11 adapter just slides into the CT as would a 1/2" shank bit.

(You are thinking of the ER20M spindle which replaced the CT completely. That is a whole different story!)

Yes - that was it!! Thank you for refreshing my memory!

Merry Christmas All
I now have the ER11 adapter and several sizes of collets for it. I have the project setup that I ordered these for, the project needs to have 1/8 and 1/16 holes drilled through 3/4 oak. I have no problem of course in doing the standard 1/8 holes, however when I try to select 1/16 bit it will not allow configuration to drill through board. What would I select in the program to drill the 1/16 holes.
I have tried making the drill hole a carve area but when I set the depth to go through board it seems to disappear from the screen but can still be seen in the carve list.
Any help would be appreciated; I hope to finish this before Christmas.
Thanks

Hi Richard,

The software limits the use of a 1/16" straight bit to a depth of .25", if I recall (due to the fragile nature of the bit).

You may want to just create shallow divots with the bit, then use the divots as a guide to manually drill through with your drill press or hand drill.

Thanks Michael, I did find away to do it. I chose the 3/16 on the pattern for the 1/16 bit in ER11 and of course the 1/8 for the 1/8 holes, it did make the pattern look strange but worked perfectly. When I loaded the ER11 with the 1/16, I stepped back to watch (just in case bit shattered), it drilled 48 1/16" holes through 3/4 oak with out appearing to strain in any way.

Thank you for the update, Richard. I thought of fooling the machine too, but was afraid to mention it as I didn't want to risk breaking your bit. Happy days though - you got away with it without issue!

I forgot to ask...did you use just a regular 1/16" drill bit in the chuck?...or did you purchase a "brand-x" 1/16" end mill instead?

Where do you find a 1/16 end mill with more than 1/4 inch cut length?
