Make Your Own ER11 Spindle

[bergerud]

A square 1/8 inch file and about an hour. I made a file handle that slides in the collet to keep it sort of straight. (I have a thread on the details of converting an ER spindle.)

I am still working on the new dust collector which uses the cut motor fan. Testing today. (I have a new ER16M spindle from Maritool yet to turn after I finish the dust collector.) Good luck with the huge ER20 when it comes. I hope to see a picture of that on the machine.

Hey Dan,,, Got my ER20... I took my time cutting it, my lathe is a 1942 model atlas,, so it doesn't have any measuring marks, all by eye and Micrometer, so it took 2 dayz, that sucker was big... top through whole was big so I after cutting, I threaded it, screwed in a bolt then cut and drilled through it.. Been filing the square hole for 2 dayzzz now,, starts movin along once UR able to work the hole file in the opening.. Almost there, maybe a test run tomorrow if I don't go golfing,, suppose to rain so we'll see... well anyway fingers crossed, seemed to be running true when I put a dial indicator on to check,, but the proof will be in the puddin >>>>!!!!

Hey you guys, when you get your new spindle up and running how about posting some pictures.

Sounds good Kevin. It only takes me about an hour to file the square hole. I guess I have just the right file. I may start on my ER16M spindle today. The Maritool spindle
( http://www.maritool.com/p951/ER16-5/...duct_info.html) is a thing of beauty. Either the Maritool ER11 I am currently using or the ER16M will be my final answer. These Maritool spindles have what is called a backup screw which is intended to stop the bit from creeping up into the spindle under heavy load conditions (milling metal). I have found this screw is very convenient as a stop for mult-bit carves. After I test the ER16M, I will post my "conclusions" as to what I think is the best spindle.

(Maritool quoted me a price of $138 each for custom made ER spindles for the Carvewright if I bought at least 12 of them.)

Jerry we have some videos up already... heres a link... Note the small size of the spindle.... http://www.youtube.com/watch?v=ZLHa5...eature=related

I think I like the ER16M spindle because it just seems like the right size and it fits so well with my dust cap. (The M is for mini nut. The ER16A types have big ugly hex nuts.) The ER16 collets go up to 3/8" and so it is more useful for experimenting with bits. The collets are longer and I think they hold the bits more accurately. This is a cheap Chinese test case ($15 on eBay). I will now adapt my expensive Maritool ER16M.

Check out the youtube video. It is also a dust cap test. Note that the carve follows the grain (sideways board). This creates large curly chips like a planer. I thought they would plug up the small out pipe but it sucked them all up.

Nice. It does not look as big as I thought it would. We need a close up of that mother holding a 1/2 inch shank bit!
