In preparation for assembling the PCB from , I printed a solder mask fixture to align the PCB with the solder mask, which came from . strangely enough, even though the names say otherwise, the companies are not related.

I have 2 medium-sized boxes of electronic components from to sort and label. Some of the resistors and capacitors are so small that it's hard to see them. it will be interesting to try and place those on the solder pads!

Finished off the DRO (Digital Readout) installation on the Lil Griz lathe. It (the DRO)will make this a really nice setup for turning small(ish) parts like top hats, or a weld b**g, or any number of things. I have got some decent tooling for it, incuding this little Bison 5C collet chuck which works reall well. I have done quite of bit of threading with it, and that was before the DRO. I still need to learn all of the funtions that are available. It will store 200 tools and their offsets which might be interesting.

Trying to get better at actually completing a project!!

Speaking of projects, work on the Late Model Stock Car chassis is ongoing just slow due to funding primarily. Turns out 1.75 OD x .090 wall cold drawn seamless tubing is very expensive and there is a lot of it in the chassis. I need sponsor(s)/car owner(s) and or investor(s)!!

Well here it is folks, my first pcb! designed in with the help of Claude AI. Three for 28 bucks from Osh Park . Next is assembly and solder. I am waiting for a stencil from . (Similarly named but the two are not affiliated). the stencil is for spreading the solder paste onto the board in all the right places. This is a development board, a little bit bigger than what the production boards will be. Everything is a bit more spread out to make it easier to work on. This way I can evaluate things, do some battery life testing and start getting things dialed in. Stay tuned!

my apologies for lack of updates and the radio silence.

The Late Model program is alive and well, just saving some cash for more tubing. just the harsh realities.

But this project has all my attention and brain power for the next few weeks. I am so close on this circuit board I can taste it. In fact, I have become so confident that I am adding features to the board I was going to save for the professionals to figure out.

This is a project that had stalled, and without it would still be stalled. So thank you Claude, whoever you are (haha), I really appreciate the help! Also to for the open-source program. There is a lot about electronics and printed circuit board design and manufacturing that I dont understand, but these two in particular (Claude AI and KiCad) as well as many others on university who give tutorials for free, are allowing me to move the ball forward.

Maybe i can combine all of this and get and my new, best friend Claude, and maybe and a few others to sponsor the late model program!

No, it's not a late model part! This incomplete circuit board is for a project that I have been working on with my friend for at least four years now. The achilles heal of this project has always been the electronics. Not that the circuitry is so complex, but it has been outside my knowledge and skill sets to do. I have consulted with several companies and estimates have ranged from $10,000 to $40,000 to get us to the point of a few prototype PCB's. These have all been good companies with good people that deserve to be paid for their work, and I would gladly have paid someone to do this, but when the funds arent there, you have to get creative to continue.
i have done a lot of electronic work and testing on the project with evaluation boards and other off the shelf solutions, so I have had an idea of what components we need and the direction to go. I have even taught myself how to work on existing PCB's, desoldering and changing resistors and capacitors to get what I want.
In the back of my mind I kept thinking and saying to myself..."you are just going to have to dig in and figure out how to design the circuitry and the PCB and do it yourself."
So this is the path I am on, but I could not have done it without the recent advancements in AI. The board shown above, which is not finished yet, is a collaboration between me, Claude AI and
If it were not for Claude AI I probably would not have ventured down this road. A simple query to Claude about the project and designing a PCB for it has led me down this road and it has re-energized me to get this project out of the shadows and out to customers.
Still a long way to go, but I feel at this point it is something I can accomplish and finish now. Hopefully in the next week or so I will be able to show the 3D model of the completed board with all of the components in place. And, at some point in the near future, I will be able to reveal the product and the whole process I have been through and how AI has helped me. Stay tuned!

Printing some seal installation tools for a customer. 25 of these for this batch. They are a part of a rebuild kit, as mentioned, to help install a small seal.

if you need any 3D printing done I have two Bambu Labs P1S printers. just DM me, or email a step file to [email protected] we can discuss material/filament or just tell me what you want it printed from, and i will work up a quote. the build envelope is 10" x 10 x 9.84" high.

Not shown here, but i am working on some 3D printed squares and angle stops for the weld table to see how they turn out and maybe offer them for sale on my website. a work in progress for now.

Speaking of the website, leeracetech.com will be getting an overhaul in the near future, by a professional that knows what he is doing, as opposed to the current version of the website which I did. i am very excited about having a website that is built by a pro. I have never had one, i have always hacked my way through wordpress or whatever and created something that was barely functional, but got the job done. I need something professionally done to move this business forward. Stay tuned

Late Model work is ongoing, waiting on some Cold Drawn Seamless tubing to bend the main hoop and roof bar, again. but more on thay later.

Enjoy the rest of your weekend

not bad for a few hours work. tomorrow when its a bit brighter over by the plasma table i will take a picture of the slag/debris from just these parts. all the material from the cuts is just blown into the water pan. good night

i gotta say, I am pretty proud of the nesting work there. the hole on the left was from the earlier batch of these probably 2 months ago. it took a number of dry runs to get that close. The question is... is the time spent worth it? Cost of steel vs cost of labor? for me, for now, it was definetly worth it, as i think this is my last piece of 11 gauge. the 11 guage is not all that expensive but nevertheless i dont want to be wasteful so it was worth it. also something satisfying about getting it that close. Pressing on...
(note to self, order more 11 gauge)

Second support tower standing for the left side A-pillar bar. I figured a way to measure the hieght of the main hoop accurately, which on the one hand showed that CAD and fixtures and main hoop hieght agree within 0.026" which is about .5 mm but on the other hand proved to me I do need to bend another main hoop. the legs of this one are about 1/8" short of touching the side rails. I would prefer not to bend another main hoop, its 117" of tubing i need other places. But thts okay, i need the practice on the bender, to get tuned up for 8 door bars with two bends each, and I will take the CAD/fixturing accuracy as a small win for the week!

i just noticed in the video i just posted that it looked like a huge gap where the A-pillar bar meets the halo (roof bar) so i want to show that the notching is much closer, but will require more work as I get all the towers and brackets bolted in place. when the dash bar is in place it will also help support everything. once brackets and towers are secure i can final fit the tubes. I always want as close to zero gap as possible.
