Re: What type of tool holder is this?

Mike Poore
 

2-A and 4-C are close, but not a match to your measurements. Is it shop made? It could be a mistake that never got scrapped. I have a couple of my own mistakes lying around that somebody will be posting questions about in 30 years.

No application for my SB9 or any of the fixtures/tooling for it. My vert mill is R8 and my horiz mill is one of the Atlas MFCs.

It is 4" long and the big end is 1.45" dia with a 1/2" hole in it. I assume for a 1/2" inch shank milling cutter.
The big end of the taper is 1.18".
The draw bar is 1/2-13.
The outer threads are 7/8-24.
The shaft is 0.8" dia and 3" long to edge of taper.

Back around 1987 I bought a Martin D28 guitar kit from St. Croix Kits now Music Makers for $299.95. Martin was selling kits of unfinished guitars that were supposed to be seconds with some slight blemish. Mine came with a note that said no blemish. I bought this just after my first wife had past away from cancer in 1986 and this project kinda kept me occupied and got me back to living again. I played it for many years . I also have a Gibson J50, a 1953 vintage.  Now at 80 years my fingers don't work so well any more. One of these days I am going to have to sell them as none of my family is interested in them.

I have cleaned single cut files, not cross cut, by pushing a narrow angle X Acto blade point first along the individual tooth valleys.

It is tedious but digs out stubborn swarf.

Dunking it briefly in a caustic solution should loosen stuff as well (hint - don't try this with your pistons or aeroplane!) and will degrease it as part of the bargain


A narrow (< 20mm) strip of mild steel works just as well for removing steel swarf from files.

Re: Hall Effect Tach on SB 9" - Solved

Here is the working version pictured below. I made an aluminum collar to go over the nut on the end of the spindle to hold the magnet and to create some space between other steel that could potentially have some magnetism. The bracket holding the sensor was installed in a bolt hole already present on the headstock, but unused on my lathe. I am not sure why that bolt hole is there. The metal case is a little unattractive, but does the job I wanted by keeping all of  the vfd and tach controls within easy reach. The original forward/reverse switch is wired into the VFD to control the motor. The ferrite choke is inside that control box. The aluminum tape on the sensor and wire was part of an experiment to eliminate the emi. It did nothing, but now I don't want to bother removing it. The only lathe modification was to file down the end of the bolt for the reverse gear flush with the nut for clearance.

Thanks everyone for thoughts. I already had a choke similar to your picture, so I installed it 1" from the display. Problem solved!

As my original post indicated, this was my suspicion, but your info helped a lot in doing it properly. Without that info, it is likely I would have done it wrong.

I will post some pictures now that I know it works in case anyone else would like to add a tach to their 9". It was a little tricky finding a spot to install it without physically altering the machine. I always try to avoid doing anything to old machines  that can't be undone such as drilling holes.

EMI from your VFD can definitely be the root cause of your problem. Ferrite common-mode chokes should be installed on both the sensor cable and the power cable, and any other cable that connects to the display unit. Choice of ferrite material and winding are important. At the expected low frequencies a Fair-Rite type 75 toroid, p/n 2675821502 is a good choice. This part is 1.22" OD and .75" ID, suitable for small cables. Wind as many turns as you can, in neat order, tightly through the core and fix them in place with a couple of cable ties. They should be installed close to the display unit. If a larger toroid is needed for fatter cable, a type 31, 2.4" OD is also a good choice. Fair-Rite p/n 2631803802. Good sources for these ferrites are Mouser and Digi-Key.

Routing the sensor cable further away from the motor leads could be helpful. Also, do not coil excess cable; that acts as a magnetic loop antenna. Cut off any excess and re-terminate.

Re: Tachulator for spindle rpm

Mike Poore
 

A little more expensive than the $18 Chicom unit I bought, but I like that it calculates fpm, which is really more important than rpm. That would be handy.

For what it’s worth, I use a Tachulator setup on two of my variable speed Atlas lathes (VFD and 3 phase motor). Works fine. Only issue is that occasionally the reflective tape gets oily or greasy and you loose the signal. Wipe off the reflective tape and back in business. The end of the sensor needs to be within 1/8” of the reflective tape.
