On the flanges - they can warp with welding. To help avoid leaks, I try to buy the ones without the mating step in them. I like the ones with a straight through bore which allows me to stick one piece of tubing out a half an inch and the other mating piece stuck in half an inch. This gives a slip fit much, much longer than the stepped flanges and in a pinch, can be sealed up with high temp RTV. In the end everything turned out good with the exhaust.... the big mistake was I didnt have the header bolted down proper... Without the vband clamp on you could see the mismatch and as I said earlier after I cut the pipe in half and tightened the clamps there was almost an 1/8 gap between the tubes and it was wider at the top.... I figure that was part of the learning curve.... As far as the shop helping me bend it they are more than willing to help... The problem is they could only do 3 out of the 4 neccessary bends...The 4th bend needs to close the gap and complete the shape.... This Is why I built what I built because it could accomplish the last bend, unfortunately I chose the wrong gauge metal... I tried to call them back today but they closed early. I was going to see what they would charge me to get me 90% there..... I could be wrong but I'm hoping if I reinforce my bending rig and they start the final bend I might be able to atleast close the gap... I could even do that releaf cut down the inside edge, atleast then it would only be one edge..... I'll see what they say Monday and go from there..... 1 Quote Link to comment
demo243 Posted December 31, 2021 Report Share Posted December 31, 2021 Relief score might help. was looking at your rig too- is it the top piece of angle iron that is flexing? maybe reinforce it with a square tube? 1 Quote Link to comment

It's a little of everything... but yes the center is flexing mostly... I was thinking about doing just like you said, reinforce the top clamp and also the part that actually makes the bend... the hinge is probably the next weakest link.... I might have to remove the pins and weld the edge that holds the pins so the metal doesnt try to unroll.... I'd really like to make all this work and not have to spend any more money.... 1 Quote Link to comment
Stoffregen Motorsports Posted December 31, 2021 Report Share Posted December 31, 2021 I think a regular finger brake could bend it. Maybe not a press brake, but a standard brake could get most of the way around and then fudge the last bend. The work piece would be forcing its way into the bender, but it will flex. Like Spicoli said - I can fix it. 1 Quote Link to comment
Crashtd420 Posted December 31, 2021 Author Report Share Posted December 31, 2021 I'm gonna see what I can accomplish this weekend and see what they say monday and go from there.... I hoping they can do 8 bends for cheap but if strengthening the rig gets the job done I'll be ok..... Trial and error.... Quote Link to comment
Crashtd420 Posted December 31, 2021 Author Report Share Posted December 31, 2021 Well it got stronger and a lot uglier... the weakest part was at the hinge and I was able weld up an edge that was bending on the inside and tacked the edges that wraps around the pin.... I know it's enough to finish 2 bends but not sure how capable it will be to do it 8 times. Trying to hold off to Monday and talk to the metal shop before I attempt anything more... 2 Quote Link to comment
Crashtd420 Posted January 4, 2022 Author Report Share Posted January 4, 2022 So they said $40 to bend them up... Not great but not horrible, so I'm having them get me as close as possible and I'll close up the last bend myself and weld it up... I cut the angles off the 2nd piece tonight so I can drop them off tomorrow.... I also contacted a local sandblaster who does mobile dustless blasting to get a quote to strip the datsun bed... not sure when that's possible due to the cold weather but I'm trying get that done as soon as possible... 1 Quote Link to comment
Stoffregen Motorsports Posted January 5, 2022 Report Share Posted January 5, 2022 In my experience, having it blasted by a shop is less expensive than having them come to your house, and there's less mess. Though transporting your bed to a shop may be a problem... BTW - I had to bend a 52" angle in 18ga steel last night. Since my largest brake is 48.5", I had to do it by hand. I clamped the piece between two pieces of angle and then clamped that to the table and beat it down with hard rubber mallets. Came out perfectly. I enjoy watching your progress Neil. You remind me a lot of me as I was learning the trade. Open to suggestions but with an I'll figure it out attitude. 1 Quote Link to comment

So I can bring it somewhere if needed. There is one guy doing the mobile blasting only a town or 2 over, I was hoping to ask my boss to let them do it out back of the shop, it's all dirt anyway.... There is a shop I could take It too, they did some blasting for me once before.... but getting there to drop it off and pick it up is tricky because their hours and me having to work... I just really want the bed back on for this coming year.... And thanks for the compliment, I figure half the enjoyment is figuring a way to do something yourself... 1 Quote Link to comment
Crashtd420 Posted January 8, 2022 Author Report Share Posted January 8, 2022 It cost me a couple extra dollars but I'm happy with what they could do for me.... They did 3 bends perfect and the final bend is 90% of the way... Should be no problem closing the gap..... 3 Quote Link to comment
Stoffregen Motorsports Posted January 10, 2022 Report Share Posted January 10, 2022 Very nice. Quote Link to comment
Crashtd420 Posted January 10, 2022 Author Report Share Posted January 10, 2022 I'm definitely happy with how they came out... I still need to weld the seam but for now they are done enough... I need to get some other things done before I get back them... This is basically what they will look like in the bed.... 2 Quote Link to comment
Crashtd420 Posted January 10, 2022 Author Report Share Posted January 10, 2022 I also got some work done making more of those door springs.... I have 4 sets spoken for, 1 more possibly or I'll keep it for myself... Still have metal to make 3 more sets after that... I should just get them all done while I'm setup for it.... 1 Quote Link to comment
Crashtd420 Posted January 10, 2022 Author Report Share Posted January 10, 2022 2 other projects I started was ... 1st I added some hood adjusters to keep the front of the hood from dancing side to side while on the freeway.... apparently I didnt take a picture.... 2nd I got started on the oil filter relocation.... mount to the block is nice and secure with plenty of threads engaged.... Filter is going under the truck next to the transmission on a bracket I'm making.... 1 Quote Link to comment

Crashtd420 Posted January 10, 2022 Author Report Share Posted January 10, 2022 This is the other half of the remote oil filter.... 2 Quote Link to comment
Crashtd420 Posted January 10, 2022 Author Report Share Posted January 10, 2022 So i have a question about the oil flow... I believe on the block, on a stock setup the oil flows into the outer portion of the filter then back out the middle into the block.... The reason I ask is because I'm wondering where to put my 2 sensors and an oil spray bar feed with the remote setup. 2 sensors are for an aftermarket gauge and dash light indicator/fuel pump cutoff. If I set the remote filter up like the factory the 2 ports on the side are before the filter.... I would assume I would want the pressure reading after the filter. 3rd location is the block which is where i planned to connect the spray bar.. Would it matter if I reversed the flow at the remote filter so the sensors are after the filtration? Also would there be any benefit to connecting the spray bar to the filter block and putting a sensor in the block? Quote Link to comment
Crashtd420 Posted January 11, 2022 Author Report Share Posted January 11, 2022 Ok answered one of my own questions, you dont wanna reverse the flow going through the filter... I guess sensors are before the filtration because I want filtered oil going through the spray bar..... 1 Quote Link to comment
