I do woodworking and metalworking as a hobby, and plan to build my own bolt action rifles.

Did you machine 100% of that bolt?

That looks good man! My only suggestion so far would be to ditch the doodoo bearings that came with the wheel and replace them with a quality set of Timken, SK , or comparable.
Your entire build is dependent on them two little chingadreros....
Thank you! I’ll try to find them

No, I have 3 bolts that came from Pacific Tool and Gauge. 3 of my blanks were EDM'd by the same guy, and the long tactical was made by a different guy.
Just to be clear, I didn't make the bolts or rem 700 blanks.
And for those wondering, it's not cheaper to build your own rifle, it's more costly in most cases.

Do any of you guys know anything about crossmembers?
Obviously this one’s shot and kenworth want $850 which seems kinda high for a 2’ piece of c-channel.
Do you think a machine or welding shop could make one for cheaper?

I dont know a ton about that world but I believe there's some hardness and metallurgical specs on some of those frame pieces. Even something like drilling the frame for a tool box mount can be a no-go technically.
Now hypothetically, yeah a welding shop could probably take care of that cheaper.
My brother fixed one of the grain trucks last year by welding a doubler plate on the inside and then welding the crack. They've fixed a lot of grain and potato trucks like that over the years

That's a tricky repair, IMO. $850 is only for the C-Channel, right? If you could get that replaced for $850, I'd say jump on it...but I'm certain that is only for the C-Channel section, right?
The basics are you need to drill the end of the crack, to prevent it from spreading after you repair it. You need to clean everything and grind a V all along the crack. You need to get all the dirt off the metal and get down to clean metal before you even start welding. Even if you weld a plate over the cracked section as mentioned by BenP, you should clean and repair the crack also, then weld the plate over the top. Should be welded with 7018 or 11018. That type of weld is best fixed with stick welding, and what is used on most heavy equipment.

Replaced the saddles on an ammonia tank Tuesday. The previous ones were very nicely coped wood, probably locust, but one side had been exposed to the elements and started to rot so they got written up for it. No way to go back with another wood piece because the piping held it all pretty rigid. So we built some stainless trusses in place.
Then we had a request to build a pallet dragger for the dock at one of the plants. I got a very low quality video of one in use and had to guess at the specs from that. I think it turned out well though.

A plant called yesterday needing an emergency piping change as ammonia was crossing into glycol lines. We surveyed, took measurements, and welded a couple pieces yesterday and then showed up at 0500 today to finish.

Pretty fun week, mostly rolling solo. Built a header for a valve cluster, finished up a hall tree, and made a piping change at one of the plants. Last one was a good chance to practice my isometric drawing.

Capped a 3 inch ammonia line and started work on some 4 inch sch10 stainless (steam line to a heat exchanger) by getting a flange welded on.

Nice weave!
The winch mounted on my chipper was on there with some one inch washers to get the needed height when I purchased it. Knew the bolts would eventually have issues because the base of the winch was only sitting on those washers.
The bolts finally snapped and it was time to put in a strong, permanent mount.
And I was very happy with my midnight welds. It’s taken a while but they are coming along now. I think building the cart was good practice!

Nothing crazy interesting going on at work recently. Well, there were a few welds up against the ceiling but there might have been some not postable climbing methods involved.
Made some stainless pans to collect hydraulic oil under molding machines. No idea why they didn't let us make them from aluminum. This was one of the bigger fab projects I've done, used a manual brake for the pans and a press brake for the handles. Not very fun to bend the stainless by hand.
Currently we are demoing some fructose and sucrose lines to get a new sucrose system installed in January. No fun at all draining these lines.

I could be hunting the rut right now. Instead I'm going to be staring at these all day.
I can not stand repetitious welding. I had to make shoe holders for a friend's wife. I politely asked how many she needed, thinking maybe 3, She asked for 10! Aluminum angle. Tried to bend the angles... snap. Then heating each bend... repetition kills creative builds for myself.
Had it been 3 I would have enjoyed the heck out of crafting though 10??? I put on the Amazon 80's rock music on the garage sound bar and went into assembly line work. I asked... Lesson learned.

Fired up the MIG for the 1st time in I don't even know how long. I'm a bit rusty, it's got some undercutting here and there. I bounced around to keep the heat manageable. Good enough for a bluing tank. I was able to use up some leftover 10ga sheet from when I built my bench.
