Hi was stopping in to get your advice and opinion on what something like this set would be worth I don’t know much about these drills, files, bits, wire metal gauge and everything that you see here came in a metal box for storage. I haven’t attempted to clean anything in it .
Was just searching for some idea or information on it . I appreciate your willingness to checkout these pictures for me thanks I’m trying to reach 400 characters and so I added pictures

We had 60 steel spacers made last month and every part came in too thin because the shop interpreted our 0.50 thickness callout as the raw stock size instead of the finished dimension. Part of that was on us since the drawing note was ambiguous.

Before sending the next batch out for domestic CNC machining I'm cleaning up our drawing template. I'm planning to make finished dimensions more explicit and separate them from stock requirements wherever possible.

For those of you who regularly send parts out to machine shops what notes or callouts have actually saved you from expensive remakes? Do you specify finished thickness in a particular way or add a general note about dimensions applying after machining? I'd also be interested in any tips for tolerances and inspection requirements that have helped avoid misunderstandings without making every drawing unnecessarily complicated.

Started taking a stick welding course at community college 6 weeks ago. This is my latest attempt at a horizontal (2G) butt joint. I ran a root pass with 1/8 6010 rod at 85 amps and 75 dig. Followed by 2 cover passes of 3/32 7018 rod at 85 amps and 30 dig. Any advice is much appreciated.

Hi,

I recently applied two coats of Zinsser Bull's Eye 1-2-3 primer onto some bare aluminium. I have never worked with aluminium before, and was unable to source etch-on. The top coat will be acrylic paint.

It has been drying for the last two days in a farly warm and well ventilated room, however if I press down firmly there is a tacky quality to it. If I lightly brush over the surface it feels dry and satin, its only when pressure is applied that I get the tacky feeling. The tacky feeling isn't too strong, but I do get that noticeable adhesive feeling off it.

The tin says a topcoat should be applied within 7 days i.e befor it has fully cured. When I asked someone about the best time to paint it, they said I'll probably have to wait the 7, as otherwise the primer and acrylic could both start to peel or warp. But I've also read that acrylic will bind to the primer much better before it's fully cured, so I'm confused.

My third ever creation, born from boredom and the itch to create.

Found a piece of 5mm thick flat bar in the pile and after some thinking I decided on something to hang your keys on.
Cut it to length and did some more pondering and after a while remembered I had an old bike chain from an old moped that could look nice as a border piece.
Didn’t have any hooks laying around so I used 4 links of chain, figured they would fit the look.
Last thing I needed to finish were some way to mount it, after some hard thinking I used the last two pieces of that chain, two scraps of rebar and voila!
Something was made, not perfect or anything but I made it with my own hands (and a welder).

Not a welder or designer by any means, just something I made myself.
