Built a dedicated table for my my Sanford. Might put the belt grinder on there as well. I plan on tearing down the grinder and doing a rebuild.

Nice job on that table. looks real nice.

I have been trying to cut some 1-1/2 -4 threads on my old 9" southbend lathe but it was having a hard time with the coarse threads so I made a adaptor to connect my 700 ridgid pipe machine to the spindle. It cut the threads like it was cutting butter. No more hand cranking.

That is awesome there!

I made this the other day.
I need to cleanup a taper attachment after weld filling.
I may add another cutter, right now in AL it's not a nice finish, but in mild steel it looks acceptable. The bulbous area above the dovetail is to offer support so I can have more extension from the quill and not lose a lot of support. I know the .5 shaft already loses some, but the extra beef helps.

R 402 should be a 30k resistor color coded orange black black - this seems to be burnt also and might have shorted out and caused the N channel MOSFET to be taken out - a MOSFET is like a switch

The blown mill Motor PC board arrived today and it is installed and it's a mill again.
All it took was cubic money. About $317.
Grizzly made it easy. All the wires were marked clearly with tags. Two plugs and about 6 wires got it done.

This is the offending PC board.

These are the offending components. The two on the right are melted and burnt.

I have no idea what they are, but replacing them would require major surgery. They are soldered in (8 pins each) and the only way to get to the back of the board would be to unsolder 24 large pins from the board that are attached to gizmos that are screwed to the heat sink on the back of the board. That would be to just get access to the 24 pins that attach the burnt components. Screws hold the other gizmos on the heat sink that can't be reached unless the pins on the gizmos are unsoldered. There is about a half inch between the bottom of the board and the heads of the phillips screw heads.

It might be possible to clip the component pins from the board and splice the new component pins to the stubs, but that would be some tricky close quarter solder work.

I think 30KΩ is orange black orange. Orange black black would be 30Ω.

Tonight I'm going to sell an extra bandsaw and then start prepping the little Atlas 10 lathe for restoration . Sawdust is covering it now . I need to do some major re-arranging in the basement and garage too !

You did a very nice job and have a very nice tool to add to your collection. Ox and Keith Rucker would be proud of your improvements.

We run F250 for rescue trucks with a staff of one Medic and one EMT. The rescue truck program was designed to save wear and tear on pumpers and ladder trucks as well as our expensive Medic transport units. The rescue trucks respond to basic 911 medical call and all structure fires and cover a larger response area. That said, they carry equipment for for all sorts of tasks. These trucks where purchased from a Ford dealer and came as base model red truck. Part of my "lite duty" responsibilities where to outfit these four new trucks with graphics, radio equipment, code three lights, camper shell, bed slider and window tint. A lot of the equipment required bracket design to secure and prevent operator injury in the event of collision. The larger rear bench seat and counsel where removed to accommodate radio equipment and ALS/BLS medical equipment. The single rear jump seat was retained for shuttling personal in the event of shift change fire scenario and can fold up when not in use.
The problem was too much loose equipment in the cab unsecured and posing a threat to the responding operators. I was asked to come up with a solution, I was also told by the maintenance superintendent (civilian) not to drill any holes in the floor, and bulkheads. Although this process took more than a day, I was able to finalize all the brackets seat belts and bungie cord mounts on the boxes. The boxes mount using the two rear drivers seat mount bolts while the rear of the box is secures at the top using the removed bench seat mounts incorporated into the cab.
The project of the day was outfitting the boxes and mounting them into the rigs (four of them). The second photo is for apartment books, maps, and quarter square and other binders and books. It sits directly under and centered to the dome/map light of the rig. The lower welded gusset brackets share the rear drivers seat mounts and are sandwiched under the seat. The rear upper bracket is not visible in the photos. The material used is 1/8" aluminum sheet TIG welded. A router was used prior to breaking to create a 1/8" bull nose on all exposed edges including the mounting brackets.



The new F250 rear doors are double hinged and can open all the way parallel with the bed for easy access of equipment. The equipment can be accessed from both the driver and passengers side with the exception of the top shelf that is blocked by the map box and dedicated on the driver side.

The drivers seat is all the way back and reclined a few inches allowing a tall operator comfort.
In closing, My department had been extremely supportive during my shoulder recovery and I wanted to contribute any way I can. The civilian side of maintenance can be challenging at times mostly due to regulation and paranoia of law suits but I'm coping the best I can.
Thanks for looking.
Turn and Burn!
