It is a company called JL Soldas, a cutting/welding company at walking distance from my house. I actually walked there to retrieve the parts!
Cost for the chassis - no bending, only cuting - was U$ 8.12. The smaller front panel, where the headphone jack and pitch bend/mod wheels are mounted, was U$ 4.49 (cutting + bending). The front panel (also cutting + bending) was U$ 19.20.

Those parts were zinc coated at another company. Total cost for the zinc was U$ 26.98 (that includes a few other small parts, such as brackets and keyboard supports), and painting added another U$ 28.78. All metal parts added up to some U$ 90, which is not bad!

I could have those cut in stainless steel; would be a bit more expensive but there would be no need for zinc coating and painting. However, I think stainless surfaces get scratched far more easily and they are hard to repair. Aluminum was another option, however anodizing such large parts is not practical, so all parts were manufactured in 1.2mm thickness carbon steel. The chassis required some aluminum brackets for structural reinforcement; the weight of the boards was causing the chassis to bend too much.

Cheers!

Which manufacturer are you using? Those bare structural panels look great. Curious what's the cost to cut and bend something that big?

Quick update: started final assembly. With the panel in place, it is just a matter of wiring the jacks and a few cables that still have to be cut to the correct length. Also, the wires to the power transistors in the PSU are too thick, this is putting too much strain in the connectors when the lid is closed, so I am replacing those.

All going well, by Monday I should have it assembled, only waiting for the wood parts and the buttons to arrive!

Cheers!

Very nice work... honestly, nice work.

Is the power transformer touching the bottom of the control panel pcb?

Not touching, pretty close but that is not the final board position. Soon as the side wood cheeks are in place, the whole front panel and its PCBs will be rised by some 6 to 8mm!

@Luismarka
Here's a DXF of the actual moog serrated style modwheel size and shape from a person who made clones from an original for their Crowminius project.
Also a couple pictures showing how he did the split and shaft lock.

Much simpler to just make a short slot in each half. Fit a square nut in the slot and you don't need a drill press.

DXF is sent as TXT because MW does not allow attached DXF. Change filename to .dxf to see and use normally.

Better take 'clone' out of the title before a mod arbitrarily closes the whole thing down. Hate to lose another great project.

I understand your reason to post this. But this project is quite a bit different than the SEM copy which was advertised from the very start as being "identical" to the original.

Here the opposite has been stated. That while its *functionally* very close it's not an actual physical clone as much as a derivative. With changed trim locations, different cabling, case, etc.

Which in my opinion is a better approach for OG re-dos anyways. Separate from the fact it doesn't break forum rules like the other one did.

FWIW, I had no part in that result beyond what I posted IN that -now deleted- thread. I imagine papazoozoo's PMs have lit up since the thread lock.

Agree. Let's make them better, not just copy the same mistakes/compromises/etc that was done 40 years ago. IE. we have better parts and manufacturing, let's use them. That's what mr.Oberheim has done with he's new designs too. But each to his/her own I guess..

Nice try to bait me into some useless OT discussion.
I didn't close that thread. Nor suggest it be closed. Moderators decided to do that. Ask them.
My post about it here acknowledges they must've had a reason to close it.

Definitely yes, it sounds just as I expected. And chances are it will outlive my very self, all components are brand new and I expect it to last some 40-50 years!

Here is another short example of what my clone sounds like.

This is the best project. How much did it cost in the end up?

Hard to tell because some of the cost was in R&D: boards that had to be revised and reordered, things that did not work and had to be done differently, lots of wiring rebuilt because I did not know the final cabling length before the case was assembled, parts that were bought in larger quantities because I may need them for other projects in the future, and parts that I already had... also, the PCB suppliers have a minimum order of 5 boards. Not significant for small boards, but 4 extra of each large board makes them very expensive. I would think I spent a total of 3 to 4 grand in US dollars. But for another unit, this would drop significantly because I already have most components and boards. And if I were to make, say, 10 units, the price break for components in this quantity is huge! Some components cost, for example, U$ 1 for one part and U$ 0.2 or so if purchased in thousands.

Cheers!

HDSP 6508 16 seg. display is a cool choice vs the OG 14 segment display. Was there much work involved in getting the multiplexed patterns to display properly or is pretty much the same decoding as the 14 seg?

I always love the lowercase letters in the display on the Lintronics upgrade.

This guy made an ASCII font for the HDSP 6508. I'm sure you want to keep it to original spec.. but it does look really cool.

I had to use the HDSP 6508 because it was not possible to find the original LT-1604. I did not change the firmware, just rewired the PCB so that the segments were connected to the same lines from the data bus. Only exception is that the original is a 14-segment, and the HP is 16-segment so I had to wire 2 segments together (segments A and D in the original are split in A1/A2 and D1/D2 in the HP display).

I am considering an Oberheim Xpander clone, so this is probably the display I am going to use if I ever decide to clone it. Apparently the display is the hardest to find part in the Xpander!

Cheers!
