That would not work for coping it will break 1st use. I have been using one of these type for 20 years, and it moves, shakes and is flimsy but it works


Definitely hit youtube for notching with chopsaw or angle grinder...amazing how good it works.

20 years ago it was $$$$ notcher, the notcher I have or grind til it fits

Youtube has made everything easier until it gets taken away

You do some really clean copes. What kind of guide are you using for the hole saws, and what do you think of this drill holder type cheap thing? Looks to me like a piece of pipe laid in the V-angled base could be clamped down against any movement, and the saw would be close enough to an accurate angle to get gokart variety copes in pipes done okay...............
Angle Drill Guide (harborfreight.com)

Yup, something like this, would be more appropriate
Tubing Notcher & Pipe Notcher (harborfreight.com)

I got one
...but, I have found that, their more for thin wall tube
...than, the steel pipe, with 1/8" wall, like I like to use

So, I "cheat"

Um...I mean I have found "other ways" ta get stuff done

Anymore, I just "rough in", the "cope", with the grinding wheel (on hand grinder)
...& then, "round" 'em & clean 'em up with......

Shhh...

...don't tell anyone

...but, I have a 1" grinding stone, mounted in a router, that rounds 'em so nice (that, I think, it makes 'em look almost, professional)

 

[Bansil]

Yeah...bro...that's cheating

Good job...my best was a 16 point cage in a 90 Amigo....what a beotch

 

[Functional Artist]

I got some more pics of my "coping rig"

It's just a router mounted to a board
...with a 1" grinding stone "chucked" in it

Plus, I practice a lot too
...I've done this many, many times

 

[Functional Artist]

Um...
Hey Mad Pro, I set up a "bench test" of the entire electrical system

I even did a video to help demonstrate it all, for ya

 

[madprofessor]

Done a good bit of notching with cutoff wheels and grinding wheels, and that's been plenty good enough for a couple of joints here and there when it's come up. I should have been more specific when asking about the cheesy drill-holder type notcher, I was only looking at it for EMT thinwall metal conduit. EMT requires a good fit due to its thin metal, can't just slop on some stick-weld to fill gaps without blowing it away. Now thinking a bench-built jig would be plenty sufficient for a little bit of joining I might do later.
The interruption circuit for your brake lights was a great idea. If you needed a brake line lock for doing burnouts then you're building the wrong kind of machine to begin with.
1K watt motor, 1K watt controller, is that match important? Of course the controller has to be at least as strong as the motor, but would overdoing it with a 2K watt controller (let's just say you happen to have one) for that motor be a bad idea, creating control errors?

I'd say that it's best to stick with "matching" components

At least until (someone ) has some advanced knowledge, on the subject
...'cause there's brushed & brushless & Sinsodial & Trapazodial & ...?
...then, ya gotta deal with the constant & peak Amp draws

Also, I made some K-Bobs & roasted potatoes for dinner, this eve

Sirloin steak pieces (marinated ~20 min. in Gingerale)
...intermingled with white onions, orange & yellow peppers
...seasoned with salt & some lemon pepper
...then, grilled to perfection (or at least "my version" of perfection)

* Spoiler:
Yup, they was yummy

 

[Functional Artist]

I got most of the electrical components mounted on the kart
...& made up a "battery box", to help protect the battery pack, while in the "stow-n-go-compartment"
...lined it with some 1/4" foam rubber (a bit of padding)
...& secured the "lid" down with a "wing nut" (for easy access)

* Had ta do some "body work" so, the brake rod would "clear" the lid, with out rubbin"
...but, yea, the battery pack should be good-n-secure

Here is a "first system check" video

 

[Functional Artist]

Worked on tidying up the wires
...wire ties are cheap (so use as many as you need)

I also, made up a bracket ta mount the tail light

It needed some nice-n-gradual bends
...so, I used a fence pole, ta help bend 'er inta shape

Yup, that should do it
...just gotta get 'er welded on (from the inside, ta maintain a nice-n-clean look

 

[madprofessor]

That's just great that you were able to make what could easily be my favorite meal, and let me see a picture of it right now of all things.
Didn't make my mouth water at all. Because my mouth still tastes vaguely of puke, no matter how I brush my teeth. Still fighting back the little bits still tossing up into the back of my throat since the weekend. Sunstroked out rigging up sun canopies over the courtyard for the Deacon's wife's funeral. (Covid, though fully vaccinated.) I hate sunstroke, ain't the first time either. The puking's the worst symptom, and the inability to use motor skills to tie a knot or use a knife ain't funny either. Unable to think what I was supposed to do with a tool in my hand, or even what I did do, or if I should lay down in the sun or the shade, or call somebody for help. Mental shutdown, scary. Guts need to settle out, no marinated steaks for me for a while yet.

 

[Bansil]

Talk about a love v/s hate post


Sorry for the lose and wishing you prayers, keep hydrated brother....

 

[Functional Artist]

Yup, I too am sorry for your loss
...but, TMI (made me wanna puke)

 

[Functional Artist]

I got the tail light bracket welded on (nice-n-clean)

Once the bracket was "in place", I lined the tail light up & marked where the bolt holes go
...then, drilled 'em
...then, taped 'em
...then, cleaned 'er up (again)
...& then, sealed 'er all up (again)

Looks "factory" to me

 

[Functional Artist]

While the primer was dryin', I worked on tidying up the tail light wiring

The (4) 12V lights are wired "in series" (so, they can operate on the 48VDC that this system provides)
...but then at the end/plug, we only need (1) red (+) positive wire & (1) black (-) negative wire

* I used some liquid electrical tape ta "glue" these little wires onto the sides
...& some random tools ta "weigh 'em down" till it "set"

** I'll put a small (15A) fuse down, just before, the speed controller connector, to help protect the circuit

 

[Functional Artist]

Ready ta get creative?

Well, I bounced around/tried some "head light" lighting ideas first

Then, got some 1/4" plywood
...& did some...well...bounced around more ideas

 

[Functional Artist]

We can get more creative than that!

So, I added another "layer" which will "raise it up" a bit & give 'er more of a 3D look
...& then another "layer", kinda like a "shaker" (more of the 3D effect)

Also, added an area for the dash board
...& then, started workin' on the "transitions" (blendin' them "layers")

 

[Functional Artist]

Ima thinkin' that "head light thing", ain't gonna work

So, I guess Ima gonna have ta make one

I got some more of that plastic, from the back of an old TV
...& the heat gun
...& started playin'

I clamped 'er ta a straight edge
...heated 'er up a bit
...& then, used a bunch of clamps ta help 'er, hold 'er, shape

* I did a "test/scrap" piece first
...& then, bent the "good one"

Next, I drilled some holes
...& installed some "headlights" which are just some 12V LED white/clear trailer lights
(remember, we need (4) of 'em wired "in series" ta work with the 48V system)

Yea, I know, it looks kinda "CHEESY"
...but, stick with me (hopefully) it gets better

** Ya know art can go either way
...super kool
...or SUPER KRAP

We'll just have ta see

 

[Functional Artist]

Did some more adventurin' & explorin' (creatively)
...& then some creatin'

Maybe a cut-out (for the (2) center headlights)
...with a bit of a "flap" at the bottom

Also, made a "sample" side piece (fender extension) outta some cardboard
...now, I can make some outta some of that 1/4" plywood

 

[Functional Artist]

I made some Cashew Chicken with some corn, mac-n-cheese & rice for dinner this evening
...& got the tail light installed

Ima thinkin' it looks "Bad Azz"
...& the Chicken was good too

 

[Functional Artist]

Hey, that Cashew Chicken looks "Bangin'"
...how did you make it?

Well, I'm glad you asked

Cleaned up some chicken breast
Salt & pepper, lightly
Sautéed in a bit of olive oil until golden brown
Added a hand full of Cashews (or 2 will do)
& then, add a can of Gingerale
Finally, simmered to reduce the liquid, until the chicken & nuts have a light golden glaze

Voilà (there ya go Ezcome-ezgo )
Slightly sweet, gingery, nutty, golden deliciousness
