As some of you know, I recently grabbed a Bridgeport clone right angle attachment from a member here, and he sold me a support and arbor at the same time!
There have been a handful of times that a horizontal mill would come in handy, so I was super happy about the acquisition! I used the right angle attachment for the project I needed, so turned to the other parts.
Unfortunately, the arbor and arbor support aren't compatible, and the arbor support isn't compatible with my mill. I am determined to fix both of these.
For those who don't know, there are two styles for arbor/support. The older style is a special bronze collet in the arbor support that the arbor spins in, and the arbor has a short part. This is the style arbor I have.
The other is just a bronze bushing in the arbor support, with the arbor having a longer area: this is the arbor support that I have
I decided to add a 1144 extension to my arbor to do this.
First, I bored a hunk of 1" 1144 to be a 2 thou press fit on the end of the arbor.
Then, I flipped it around and faced the other side.
I used some loctite 609 and a lead mallet to be hammer them together, after I discovered that my arbor press is roughly 2" too short for this job
Next, a quick centering in my 4 jaw:
I center drilled it for tail support, then turned it down to a sliding fit in the arbor support:
Next, I'll start working on making the arbor support work with my mill.
