Rear Mounted Tool Post for SB 9" Lathes

 
Edited

Mike Allen asked for more info on the rear mounted tool post seen on my SB 9". This came to me with the lathe. It's an added dovetail to the cross slide. Held by four smallish cap screws it's not the world most rigid set up. In fact, I've yet to use it! These are frequently speced as useful for an inverted cutoff blade, but I have been parting from the front forever and usually don't have a problem. (I don't part off 4" diameter slugs!)?

Right now it works well as a flat spot for the cutting fluid!

Now don't ask what the three tapped holes down the middle of my half nut lever are for, I don't know! (Someone suggested they were for mounting parts for an 'automatic' disengagement mechanism.)

PS: Are photos being automatically reduced in size? My originals are much higher resolution...

Photos 0 and 1 show a very different paint finish.? Was there a significant time interval ?? ?What did you use to clean the "dark brown haze" from the surfaces?? ?
It looks beautiful.?

I bought the lathe in about 1985. It sat uncleaned and unused until about ten years ago when I disassembled, cleaned and painted it. I was going to use the cast iron legs from my Enco12x36 which I built a steel bench for, but the mounting surface board I made almost perfectly fit an old desk I was breaking up for firewood. Glad I did, the desk is much more stable.

I upgraded the reverse lever using a flame cut plate for the sector. Then I had a problem changing belt speed as the four step sheaves that came with the lathe were very close to the headstock. I found a headstock that incorporated the quick reverse lever and found that it offered an extra 1/2" clearance for the sheave,

Vary nice lathe now, though I wish I had used a darker gray paint!

Hit send too quick, here's some more photos. Headstock casting photo from ebay listing, comparison of the two headstocks (note the modified quick reverse and the new stock quick reverse mounts). Last is showing new headstock with more belt clearance.?
