    front panel removal G0620

    I am stumped trying to figure out how to remove the front panel on my lathe. Manual is no help. I have a short in the switch box and need to get to the wiring. I can see the quick change knobs have set screws, two each opposite each other. The start, forward and reverse and the red paddle switch...

    R-8 spindle cleaner

    Thanks Steve, what I did was make the cleaner from acetal and milled a 1/8" wide x 3/16" deep slots. I did not have felt or leather on hand and used 1/8" cork instead. I glued it up with wonder glue yesterday and today I trimmed the excess. Sprayed WD-40 in the spindle and then held the shop...

    R-8 spindle cleaner

    My mill has an R-8 spindle. Yesterday I had trouble removing an end mill holder. Tried tapping the bolt with a dead blow hammer as I usually do. After about 6 or 7 blows I went and got an 8lb sledge hammer. I gently tapped the bolt and the holder dropped down. I assumed the problem was with the...

    Drilling and tapping carriage for rear tool post

    Grizzly 10x22 lathe. I have drilled and tapped the carriage, it is cast iron and very easy to drill and tap. I changed from 1/4-20 to 10/24 . This required smaller holes and still plenty strong. I am done and tried the tool post last night. Worked great for parting 3" 6061 aluminum. I never...

    Drilling and tapping carriage for rear tool post

    I am making a rear mounted tool post. I will have to bore holes in the carriage for 1/4-20 cap screws. I am wondering if cobalt drills or even HSS drills will work. Also , will HSS endmills work for a counterbore. Only 4 holes are needed. I will start with #6 drill and try to tap the hole. mike

    PM Research #5 - how do I bore the main crankshaft journals?

    I usually grind the front relief 10°. Side rake and back rake about 15°. Different materials call for different angles. I usually just use the same ones for every metal. It is rare that I have to bore smaller bores . Little Machine Shop has an informative article on grinding HSS lathe cutters...

    PM Research #5 - how do I bore the main crankshaft journals?

    Make your small boring bars from Allen wrenches. The steel is very hard. I use a Dremel tool and cut off wheel to reduce the short leg to a length needed. Even the front relief can be roughly done with a Dremel tool. mike

    Silver solder or braze

    Why change from solid to soldered joints? Silver solder is hard solder and melts at average temperature above 1100° depending on the make up. There are some hard solders that melt at about 850° and others at a high of about 1400°. Sometimes hard soldering is known as silver brazing or just...

    Build my own milling machine

    I think you are making a mistake building your own mill. There probably are many used mills or even new ones that would cost less than trying to make your own. I have an acquaintance who bought a new South Bend lathe, deep pockets I suppose. Now he wants to save money and build his own mill. I...

    vacuum for use on a lathe

    At first I used a small vacuum with a 1-1/4" hose. Clogged up often. I switched to my old reliable Craftsmen 6 gallon , 2-1/4 hose. I rarely have to unclog the hose now. I placed a tray I made under the bed to hold most of the swarf. I pull the tray and dump it , then vacuum what's leftover. mike

    Zip Wall for Shop Heat Containment?

    I built a 8'-0" x 12'-0" enclosure that was removable for a customer. This was a pantry in his garage. I screwed 1/4" plywood on each side of 3-1/2" metal studs 2'-0" on center. The studs had fiberglass insulation taped to the studs. The long side has three 4'-0" panels , short side has two...

    broken saddle lock screw

    I spent about 4 hours on it today. I separated the saddle from the carriage only 3/16". That was enough to get a 24TPI sabre saw blade over the clamp screw. I had to make a holder for the blade. Hack saw blades were too wide and flimsy. I cut thru the M8 screw , took several hours as the screw...

    broken saddle lock screw

    Today I broke the screw that locks the saddle to the bed. The lathe is 10x22 G0602 .The screw is probably cross threaded. I'm afraid I'll have to remove the clamp to back out the screw. The top of the screw is broken about 1/8" below the saddle. I am not sure how to remove the saddle clamp. I...
