Specs measurements for MT drawbar arbors - The Hobby-Machinist Are there specifications for drawbar style tooling arbors relative to the axial position of the drawbar thread hole relative to the arbor taper and for the depth of the tapped hole for arbors with 2MT taper and M10 drawbar thread?
Morse Taper spindles and drawbars - Practical Machinist To remove the collet chuck or arbor the drawbar is removed and replaced with a duplicate of the drawbar, only without the head Basically a simple rod would do, mine will thread into the arbor This rod sits higher than the top of the spindle
How do drawbars in milling machines work? : r AskEngineers - Reddit I've been trying to understand some of the mechanical details within the tool holding portions of a milling machine From the diagrams I have looked at however, I have not been able to see any detailed explanation of how the collet (arbor? Other tool holding terminology?) is held by the drawbar

Tapping Arbor for the drawbar - The Hobby-Machinist I'll keep the arbors in the drawer when I get something stouter, better, more expensive to get it done Being tapered on each end, I held it between wood blocks for tapping For drilling, I put the chuck and arbor together and chucked it up in the lathe to keep the hole concentric
Deckel FP1 Draw Bar Question - Practical Machinist The original would have had female threads on the vertical head bar, like your horizontal drawbar but you could make a drawbar that accepts tooling with internal threads if you want (probably more of an issue on the no 40 machines than the MT4 machines)
Brown Sharpe #9 taper tools arbors | The Hobby-Machinist I have an older US Machine Tools #1 horizontal mill It uses a B S #9 taper This particular machine doesn't use a drawbar to pull the arbor into the machine socket As mentioned, the arbor has a female thread on the rear It's pulled tight into the socket with 1 2-13 a bolt
Index model 40H drawbar mod - The Hobby-Machinist Today, I made a simple modification to the drawbar on my Index Model 40H vertical mill The original arrangement on the mill requires that the arbor or collet to be released by loosening the drawbar nut and hitting the drawbar with a hammer
