Re: Collet Rack Angle

Webb, If you need measurements of the support tube, I can take some photos of it on my 10L Toolroom lathe and mark them up.

I'll get top drilling that hole tomorrow.  I'll take some pics for you-all.

Re: Which do I keep? 1949 9" Tool Room or 1935 9" Heavy

Stuart Wilby
 

Have a good retirement Vince, I bought my SB 9” a few years before retiring along with some accessories, it soon became clear to me that one machine was perfect for my hobbies, motorcycle repair and general machining on a small scale, however, it became clearer by the day after I retired that one lathe was not enough, so I bought another Lathe and built a dedicated space to work in and keep it all together, the lathe had a milling slide which has its uses alongside the milling machine, my advice would be to keep both machines if you have the space just because you can, they take some finding these days, have a good think before selling and I’ll guarantee this, if you sell one, inside a week you’ll regret it when that need appears at your workshop door.

replacement for compound slide

Jack Dinan
 

Saw a video where the author eliminated chatter on his PM lathe by replacing the compound with a block of metal.
Can anyone provide info on doing this for a SB 9A?

Webb,

I believe it’s 30 degrees.

Hi There,

I purchased a collet rack casting from Fred and I would like
to know the angle the rack sits at so to be able to drill the
hole for the support pipe at the correct angle.

Anybody know this angle for sure?

Thanks in Advanced!

Re: Lever retractable threading tool

Ondrej Krejci
 

Greetings,

To elaborate on why instantaneous reversing is needed, to get the intended use from this clapper style threading tool the split nut should stay engaged and no pulling out of the tool should be required, and the the carriage is unwound back to the starting position.  Without some kind of instantaneaous reversing, some good timing for coasting till the motor can be reversed or stops will be necessary.  Just switching to reverse with a regular single phase induction motor running at full to 75% speed will keep it running forward.  One can also use a piece of wood to brake against the chuck or face plate, but that is tedious from personal experience.

Enjoy,


OK

I just keep mine in 2 rollaways just for Lathe and Milling Machine tooling.  Keeps it neat and organized, does't get dirty from sitting out.  Plenty of room for my 3C, 5C, ER40 collets, AXA tool holders, end mills, ect.  Since I have both an SB9A and a SB13, i made an adapter plate to raise the tooling on the 13 so I don't have to reset them from lathe to lathe.

Here is my version of the rack. I ground a bevel on the brackets to fit the dove tail of the holder as the bar was slightly wider than the dovetail.

There are forces other than gravity that might knock a holder up and out ... like my clumsy hands, when reaching for an adjacent tool holder.
