yep now it's time for another bracket

tab this one's gonna be kind of similar to the one Rennline offers also Sierra

Madre has one I'm gonna do a little bit of both and I'll tell you why it's gonna

be different so I'm gonna run aluminum bars between the struts and I also want

to run a diagonal bar down to this corner now the diagonal bar for the off

the shelf brackets doesn't have a place to tie it in so a lot of people tie it

in to the sheet metal so rather than drill another hole in the

car I would rather make a unique bracket on the passenger side plus you know I

like to save money those things are about 180 bucks so I'm just gonna do a

one dimensional profile on this blue paper and I'm going to transfer it into

a three-dimensional shape with sheet metal

hmm a little little change of venue I'm here inside the house now and I'm at my

laptop I just want to show you how I got that paper template using my computer

yeah this is an engineering software it's called SolidWorks and what I've

done is I've taken this template that I've scribbled on and cut out on the car

and I've scanned it and I've imported it into this software so you can see this

shape here if i zoom in you can see these are my kind of squiggly lines and

then I've traced it with true arcs to sort of even out all the undularities

of my cutting scissor method so this is fully outlined with these black lines

and then this is a three-dimensional tool so I can turn this into three

dimensions pretty easily this is a sheet metal module so it allows me to create

it in three dimensions and then it allows me to flatten it so there it is

flattened I was able to electronically put these holes at equal distances get

these holes here centered around that arc it just makes it easier and then I'm

able to print this in one-to-one scale so here's here's the page that I print

and it has a few you know dimensions on it just for my own use not fully

dimension but good enough for me so what I do is I print this out I cut it out

with scissors once again this time the lines are a little bit more accurate and

then I trace that onto the metal and I did the plasma cutter everything else

was was done from there so this is a little bit of a look into kind of my

engineering world pretty simple takes me just a few minutes and really gives a

better outcome

I got this piece cut out and it's looking really good I was unable to bend

it the full 90 degrees because the limitations of the break so I'm gonna

have to hammer the rest of this but now that the the flange is started it's

definitely helpful I'll probably end up using the vise in the table just kind of

hammer this back to a 90 degree Bend these are supposed to be you know

straight up and down and I put in the holes for more speed holes so to match

the back I want to put more holes in so on this one it's a pretty compact area

and it's a different size than in the rear so I'm going to make some steel

dyes that will do the the dimples here

you

okay what I thought was gonna be a simple job of making some dimple ties

proved to be not so simple just like everything else I was able to get this

one done this is the the male portion of the dimple diet this was pretty

straightforward however I ran into some trouble on the female side this is the

the female side and this internal chamfer was a little more difficult than

I expected the tooling available is limited it's a community-based workshop

and the tooling is is is free it's available but you don't always have what

you need so the all the cutters were sort of for external cutting faces open

faces the so the tool holder itself was actually running into the the small hole

here so what I really needed was a boring bar and the boring bars they had

were too large too big visit 3/8 diameter hole so I'm gonna have to go

back into my own shop and and figure something out I can rough this out with

what's almost anything just need to create kind of a conical hole doesn't

need to be precise it just needs to be able to you know drive the sheet metal

down inside there so that's where I'm at I will be back at home in a few minutes

yes this is this is rain on the the window by the way does actually rain so

California first time I'm like I don't know three months okay here's where I'm

at with this female portion of the dimple die so I've I've taken the die

and I kind of pushed it on to this three-eighths inch shaft so it's I hope

it'll stay on here it's kind of a kind of a friction fit it feels okay so I'm

going to now grind the chamfered shape into this part I'm just gonna spin it

and then use my my grinder on the inside now I do have some countersink tools

that I think are 45 degrees or er close to 45 degrees but I'm not going to

destroy them on this material this is stainless steel it's actually very

difficult to machine so the only thing I feel comfortable with with the tools

that I have is because I don't have the carbide tools

I'm just gonna use the grinding wheel this is from a this shaft is from a

jetski drive shaft so I know it's stainless steel it is a machinable

stainless steel because that's how the the the shaft was made

you

here's the formed piece and impressions came out really nice it's it's very

crisp especially on the backside which you won't be able to see for this part

but it's a pretty deep dimple I did 45 degree chamfer 's so it goes down pretty

deep the hole does open up a little bit it's bigger than three eighths now after

the metal you know extra stretches but I'm pretty happy with this you might

have been cringing or chuckling at my machinist methods but you know at the

end of the day I was trying to make a sheet metal part and it works

you

okay all is going pretty well with these parts I did make two of the identical

parts the passenger side is going to be modified on the lower section so I

mentioned that these are the strut tower braces and there's a bar that goes

between them but there's also a diagonal bar that goes from here down to here so

I'm gonna be adding some additional brackets on here

I couldn't form them into the part because this metal is already formed

down and I want to form it up as well so I'm gonna have to add some metal on that

so I'm gonna be working on that too but I wanted to make two at the same time

because it's just quicker now I'm ready to put the dimples in and the dimple die

here on the top is is working like it should I drilled the holes and this is

going in everything's good now this piece is too big to go between here like

this so it's just a little too big now I remembered that this is one-inch on the

internal and I was supposed to at the workshop I was supposed to mill the

edges flat so I'm not able to do that since I'm at home now I'm going to just

put this in my vise and just grind it off with a big grinder so this will go

down inside the channel and then I can squeeze the dimples in

you

all right there it is just sort of taped in place the side here is gonna need a

little bit of trimming just just to make it fit more flushed prior to welding I'm

not gonna weld the entire length of this I'm just gonna stitch well that a few

different areas but it's it's roughly in position I'd love to tack it in right

now but I'm not gonna I'm not gonna do that until I put the strut back in and

and lower the car back down on its four wheels I don't want any sort of rotation

in the chassis or twist in the chassis to be locked in place by welding it this

far I don't think it's gonna distort too much based on the way the car supported

but I want to be safe and I also want to take my time and strip some paint off

and and actually do some seam welding for instance right here is a seam which

could be welded there's a lot of seams here in the front along these gas tank

support panels that I'm gonna try to and try to improve by welding all right I'm

really happy with the way this piece turned out the dimples I think look

great didn't distort the part too much I just put these holes in here these holes

are a little small I don't know what kind of hardware I'm gonna be putting in

here yet so I'd rather just have some some pilot holes there I can always

punch him out bigger later once it's even welded in the car but this is a

little coming together pretty nicely who knows if these changes are actually

going to be noticeable in the way the car drives have a feeling that just the

bracket itself does increase the stiffness of the shock tower and then

when you tie the two together with a strut bar going across I really do

believe that's it's beneficial so thanks again for watching and we will see you

next week take care
