Re: [time-nuts] TAPR Oncore M12+ kit

There is a brief description of the parts included in the kit here: http://www.synergy-gps.com/index.php?option=com_content=view=54=73 It includes end plate dimensions and hole locations, etc. We have added paragraph 5 to the document as follows. It will be on the web site tomorrow. Art 5. The

Re: [time-nuts] TAPR Oncore M12+ kit

I earlier sent Jerry a copy of the pdf that contains the drawings of the two end plates and we have corresponded briefly about his process. I have told Steve WB0DBS I will buy two sets of the two end plates. Yes, I could fabricate these but the real ones are die cast and have a sealing gasket

Re: [time-nuts] TAPR Oncore M12+ kit

Milling internally and externally to the perimeter of the board is a price adder, but is routinely done and not expensive. I've done round PCBs with large, oddly shaped "round" holes in the middle, impossible to drill. I've done PCBs where the outer corners had to be milled to a specific

Re: [time-nuts] TAPR Oncore M12+ kit

Hi Well … keep in mind that my plan was to print the parts I need :) It sounds like there are enough people interested to get an order going for a couple dozen sets. I’d guess more interest in a fully hogged out set than in the “drill it yourself” approach. That assumes the cost does not go

Re: [time-nuts] TAPR Oncore M12+ kit

One other point, if you have the plates and just need them milled, that is pretty easy work. I could make the model from the drawings and then just run them off. The only challenge is that something always goes wrong no matter how careful I am so ideally, it would be best to be able to

Re: [time-nuts] TAPR Oncore M12+ kit

I would mill them for the price of shipping just to help out. It would take about 10 minutes of setup and machining for the front panel and maybe a little longer for the back. I could do two dozen pretty quickly on a weekend afternoon. I mill keyed BNC and DBx connectors all the time. >

Re: [time-nuts] TAPR Oncore M12+ kit

do they need to be inset as in the drawing or will a flat piece of aluminum work? I have some .25 thick aluminum. I could mill a pocket which would add to the design and then mill the holes for the components. That would take more machine time is all. Generally, the way I mill plates such

Re: [time-nuts] TAPR Oncore M12+ kit

Hi If you ever get a chance to visit a PCB fab it’s an interesting sort of process. No two of them are quite the same. The gear they have does impact what they can or can’t do. Every one I have ever visited has done routing on the boards. That may be because it is a very common requirement on

Re: [time-nuts] TAPR Oncore M12+ kit

Hi The dimensions, including the holes that need to be CNC’d into the plates are attached an earlier message in this thread. The main link is: http://www.synergy-gps.com/index.php?option=com_content=view=54=73 The dimensions

Re: [time-nuts] TAPR Oncore M12+ kit

Is there a way I can help with this project? If I had the specs to look at, maybe I would be able to run off a bunch of plates. If we could batch them up I would do them for the cost of shipping. Does anyone have a dimensioned print, picture, cad drawing of the plates? > On Apr 28, 2017,

Re: [time-nuts] TAPR Oncore M12+ kit

Hi Bob, It may be because the process of cutting the boards apart is not part of the board milling process.  Yes, cutting holes in boards for through-hole parts is part of the business - round holes.  The fab house for OSHPark won't make oval holes.  They won't overlap two holes, either, nor

Hi If you go with the PCB approach, the nice thing is getting stuff like the slot for the D connector done at the PCB fab. That way you have something that drops right in and works. The downside is that not every pcb house is happy doing that sort of “CNC work”. I have absolutely no idea why.

Re: [time-nuts] TAPR Oncore M12+ kit

I've got some of those aluminum boxes. It is not hard to make your own end plates. All out need is either some aluminum strips (they sell them at Home Depot or a piece of copper clad PCB material and two screws. If you really want the interlocking groove then you make two plates for each

Re: [time-nuts] TAPR Oncore M12+ kit

I was hoping that someone would design some end plates from PCBs -- it just needs the PCB design and then the production is easy. I've built cases before with PCBs as the front and rear panels -- they look nice. I'm in for a group buy Philip On 28/04/2017 08:19, Stan wrote: I would be

Phoenix Meccano has a bunch of nice aluminum extrusions (with card slots) usable for instruments and such. Minimum order is a nit. (Their stuff is nice but $$$) They deal with the public easily. Placed an order this past summer. A week later, they called and asked me to certify that the

Re: [time-nuts] TAPR Oncore M12+ kit

Hi Another possible answer for end plates is to 3D print them. Doing it cheaply is not going to do you any good EMI wise (it’s plastic). It will keep dust and bugs out of the enclosure. Doing it with a metal loaded material is probably less than $7 an endplate, but not as good looking as

Re: [time-nuts] TAPR Oncore M12+ kit

I would be interested in participating in a group buy for the end plates. I will need two of them. Regards, Stan N6BYU Date: Fri, 28 Apr 2017 09:56:55 +0100 From: Steve - Home To: Discussion of precise time and frequency measurement Subject:

Re: [time-nuts] TAPR Oncore M12+ kit

All, To add to the excellent information Art has provided - I spoke with Candice Rincon at Phoenix Mecano and just received a quote from her for the end plates. There is a $100 minimum order policy at P-M, shipping and taxes additional. The end plates with gaskets and screws are $7.25 each so
