I think the biggest issue I find with all of the welding carts I’ve come across is those stupid little pivot wheels in the front. Why does everyone do that? You have grit, metal chunks, cords, ground cables and all sorts of things on the floor and those stupid tiny wheels get caught up on all of...
9x42. It’s in good shape but not perfect. It did however come with a complete extra J head, motor and all the parts.
The lathe is a 1960 13x36

I picked up this old Bridgeport mill and Clausing lathe last month.
The motor on the power feed for the Bridgeport needed rebuilt and the DRO needed to be trashed. They both are very tight and work well.
A little love, new DRO and some tooling and we can now make things.

The vise was in ok shape when I got it. I’ve dated it somewhere around 1880. I cleaned it up and painted it.
The stand is made from A588 weathering steel. No paint.
I tabbed and slotted all parts together to minimize the fillet welding and it makes it easier to assemble.

I built the frame on a machined table from work.
I brought the frame home and leveled it out with a laser. Then I set the top on the frame and used the holes in the top to clamp the top to the frame. I checked the top at that time for flatness and it was really good.
The way the tab and slots...
Thanks for the confidence. I let things settle. Sometimes people who whine a lot are blowing their own smoke because they haven’t figured out something can be done.
It’s all good. I’m quite please with my creation.
Have a great day

With exception to the one corner I feel like the fab of this table is a complete success. Having kept the welding of the top to the frame at an absolute minim via tab and slot connection plates it was fairly easy.
I used 1-5 acme rod leveling feet with 10” of throw for work height...
Thought I’d update this thread. After successfully assembling my table I have one corner that has a little warp in the plate. Other than this corner (about 3” from an edge) I have an average profile over the top of .007 which is close enough without any grinding or other Bs.
It’s all about the...
Originally yes. I think .015 is attainable.
Once it’s all fabricated I will have the one surface ground. I’ve got a few favors owed to me.

Size does matter when you are looking at the tolerance.
My frame does have adjustable feet. The flex is always something to consider.
The frame will bed fit and welded on a granite slap at the big shop I run.
I’ve also been designing and building machining fixtures for a number of years...
I’ve seen bad. This plate is pretty clean and really quite flat.
We will see how it all turns out when complete. I’m confident in my ability

I’ve been in the industry a long time. The thickness and flatness don’t go hand in hand.
Thickness is measured within 2” of a master plate at the mill. A master plate can have a mild crown in it. The sub plates you get out of a master plate can come from anywhere in the master. The sub plates...
That .03 tolerance is the Mill spec for thickness not flatness.
I built a few tables for shops with a .01 flatness tolerance
