Re: Help with WW II markings on SB 10L

My guess would be the initials of the naval inspectors at the SB factory. It could have been sent to the shipyard or it may have served aboard a ship; battleship, carrier, repair ship, cruiser, sub or destroyer tender. I have a Sheldon war time lathe that served aboard a liberty ship.

Re: LED Shop Lighting

I purchased some Barrina 4' T5 strip lights, 6500K, from Amazon for under $40.00 in a pack of 6. Very bright. I ordered more. They also have T8, 8' LED replacements for fluorescent fixtures for less than $100 for a pack of 12. That's a better deal than my shop-made ones. Correction: A pack of 12 8'...

Re: First time using super glue chuck

Yep! Many years ago, I made more than 200 of these---block tolerance was ± .003", with much tighter tolerance on several features, the closest being only .0002". The production method was as I described, with 26 setups in total. Every cut was taken on the mill (my Bridgeport), including the turns o...

Re: Runout Wobble on the Chuck?

I think the only true way to determine if the headstock spindle and bearings are true is to mount a long bar between centers using a dog and driving plate. If the turned diameter at both ends of the bar (say 12" long) are identical, then you will know the spindle is not bent and the bearings are sti...

Re: First time using super glue chuck

So far the glue joints have failed, but I have been able to make 12 parts, all identical (well almost identical) the lack of identicallity will not affect their function. The drilled holes and slots are well within tolerances. Taking each on a case-by-case basis, I will be able to complete my projec...

Re: Mill and Lathe Recommendations for High School Machine Shop

I would avoid all used machines, unless they are not more than 10 years old. Students will break something on a machine and it would be hard if not impossible to find a repair part. Stick with machines made in Asia. I would recommend Baileigh, Jet, Grizzly, and other oriental machines. A used machin...

Re: First time using super glue chuck

Thanks all for your experience. The learning curve is long in the world of machining and sometimes I think I'm going backwards. Thanks for keeping me on track.

Re: First time using super glue chuck

If I made them individually, I would be cutting 8 pieces, chucking each one up in the vise. It seems it would be a lot more work doing it that way. Making it from a strip minimizes setup. The super glue failed on another setup I was machining, so I need to rethink it. I can do all the machining, but...

Re: First time using super glue chuck

Trying to clarify what I'm trying to do: As the picture shows, is a piece of brass bar, 1/4"x5/8"x2.875" long attached to the aluminum waster piece by tape or super glue. After all the slots and holes are made, I want to use an 1/8" end mill to separate each piece from the brass bar leaving 8 identi...

Re: First time using super glue chuck

I've tried carpet tape to hold aluminum stock for milling with success. I want to use either a glue or tape that will hold the work without failure. Here is a sample part I am making. It is laid out on a 3/8x3/8 brass bar attached to an aluminum waster. After machining, I have to separate each piece...
