For sale: Craftsman 109.20630 6x12" Lathe. --Sold--

This has been carefully restored. This is not one of those, clean it up and paint it to sell lathes that just look nice. This restoration was to try to get the lathe accurate an reliable. I was not interested in a museum piece; this is something I wanted to use.

When I received it, it had many problems. Some of the fixes are shown on the menu above. I have spent nearly a year getting the parts, upgrading things and fixing the problems. Finally it is in a usable condition; in some cases better than new.

Repairs/Mods/Upgrades (cost):

• Replace bed clamps with brass for tighter fit with less drag.
• New front spindle bearing. ($40)
• New spindle made from hard tool stock (stronger than original.) (worth $100)
• Sherline cross slide for accurate cuts with 0-0.050" graduated dial. ($80)
• Almost brand new Sherline live center. ($40)
• A2Z Quick Change Tool Post with 4 QC tool holders: 2 regular, boring bar holder and cutoff tool holder. ($80)
• Replaced missing gears ($50)
• Made custom counter shaft assembly to get speeds down as to not burn spindle again.
• Replaced belt with genuine Fenner Drive Power Twist Plus Link V-belt (not Chinese copy.) ($30)
• Replaced wrong speed motor with 1/3 HP 1750 RPM motor. ($65)
• Replaced tail stock shaft with longer one with 1/2-20 threaded end (allows using 1/2" drill chuck close to tail stock.) ($40)
• Added heavy-duty 4" chuck. ($100)
• Spindle reworked with additional brass thrust washers for less friction.

Lathe includes:

• Reprint of User Manual, Gear Chart and Parts List.
• Instructions on my changes.
• Wood stand.
• New stronger spindle and original.
• Full set of change gears, complete set with a few duplicates. Some look never used.
• counter shaft to reduce speed and lessen wear on spindle bearing (original bearing was shot from too fast speed especially with a 3600 RPM motor.)
• 3/8" and 1/4" drill chucks with MT#0 mounts and two keys. ($30)
• Original 3", 4-jaw independent chuck with key.
• Unknown make, heavy duty 4" 3-jaw self centering chuck with key. Also has the set of reverse jaws. ($100)

• Two lengths of 9/16" 12L14 hex bar stock. 12L14 is specially made for easy machining.

The lathe is now working better than ever. I hate to sell it with all the work I have in it. I swore at this lathe for a long time with its problems. Now, it is actually nice to use and works well. But, has to go as I found a deal on a bigger lathe and now have no room. So, has to go.

All needed fixes have been done for proper operation. Has power feed and thread cutting capability.

The lathe itself usually sells for about $250 on ebay. That is for an unknown condition lathe usually missing parts. Add up all the prices shown above and you see I have nearly $700 in upgrades and tooling.

Here are some notes I have on using this lathe.

	Craftsman 109.20260 Lathe mounted on stand.  A2Z QC tool post mounted on Sherline cross slide. I had a Sherline lathe, it was very accurate, but just too small. This cross slide give the accuacy on this older lathe. You lose the compound slide capability but gain accuracy and a tighter cross slide with more tool mounting options. The original slide can be installed if needed for turning tapers or easier threading. 4" Heavy-duty, self-centering chuck installed. This has improved workability immensely. The stock 4-jaw chuck is weak. It also moves the work a bit farther out; that helps as there is a bit of wear near the head stock (only enough to notice change in drag on carriage.) New 3/18" chuck in spindle. (click on image for large view)
	Counter shaft setup. The tensioner helps keep down vibration. The Link Belt also reduces vibration. 8-speeds easily done. Complete Gear assembly.
	Top row: Indexed Carbide Tool bits and change gears. Bottom row: left to right: 4 QC tool holders, Parting tool, boring bar and 2 regular. Allen wrenches for QC tool holders. 1/4" Drill chuck. Four Chuck Keys for 1/4" chuck, 3/18" chuck, 3" 4-jaw chuck and 4" 3-jaw chuck. T-nut to mount the A2Z tool holder on the original compound slide. Original 3" independent chuck has been bead blasted to clean up grime.
	5-piece, 1/4" indexed carbide tool bits with extra screws and two torx bits. These cutters have really improved the operation of the lathe. Since I bought the set, I have never used the other carbide or HSS bits. (the two missing ones are mounted in the QC holders shown above.) Each tool has 3 faces. Probably 5 faces are used of the 15, one is chipped. The remaining 14 are as new.
	Top Row: 10-piece 5/16" carbide tool bits. Most are used. Middle Row: Four center drills, Three 3/16" new HSS cutters Bottom Row: 1/4" HSS cutoff tool, some used 1/4" cutters.
	Top row: dead centers for tail stock and head stock. Extra T-nuts for cross slide. Middle Row: Sherline Live Center, brass Gibbs for original cross slide and used brass thrust washer for spindle. Bottom Row: Extra #10-32 screws; Original carriage front clamps and original tail stock ram.
	Top Row: Original 24-TPI cross-slide feed screw, handmade 20-TPI feed screw, bolts/nuts for compound slide. Middle Row: Four boring bars Bottom Row: Second set of jaws for 4" chuck . Never used, still in packaging.
	Original compound slide, base and handle. Original rear clamp and spindle bearing Link-Belt instructions 2 pieces of 9/16 12L14 bar stock, real nice machining steel.
	Old vanity cabinet for base. Has 2 doors and 2 drawers for storage
	Unopened Mobil Way and Spindle oil. I bough this as soon as I decided to sell the lathe. Proper oiling is critical for smooth operation and to prevent wear. With this modern oil, the lathe should last indefinitely.
