Watching the proses is part of the fun

I'm hoping to have the assembly done this weekend, I know the thread is pointless without pics I didn't wanna post pictures of the 3d model just to find out I couldn't do it and look like a tool

I'm going ghetto on my holds I've got a couple step blocks with hold downs. basically put my delrin ontop of a small piece of maple that I faced with the machine to make sure it's 'square' to the machine then just set the delrin on it and hold it down on either side with step blocks. I'm not machining fast or hard so the hold doesn't have to be rock solid.

In the future when I nest parts to run multiple in a single operation I'll be making an aluminum tooling plate with some bolt holes specifically for the stock I'm using. Nothin too fancy.

 

[Lance_Wallen]

this whole thing has been an excersize in patience and self learning. I'm basically teaching myself 3d modeling, CAD/CAM software, CNC controller software and how to machine while trying to create a real product with a good build quality.

I've got an engineering background so a lot of the details are easy but the process is something that usually went to some one who knew how to do this crap. It's been fun and frustrating at the same time.

Sounds like you are making progress.....be interesting to see the first prototype......my 20d is in the planning stages now....but am building another dna at the moment....

 

[Lance_Wallen]

well, prototype 1 is a failure. I made some critical mistakes in some assumptions regarding how much space i needed for wires. Gonna have to go back to the drawing board. I'm considering ditching the charging circuit too and just using replaceable batteries.

Heres the promise pic, the black part is the RBA, white part is obviously the case. Holding it with a provari with the extension cap on it an a standard liquinator tank for size comparison.

 

[Lance_Wallen]

Heres the one with the provari.

First prototype enclosure looks nice....pm coming your way...

 

[Lance_Wallen]

the main issue outside of the fact that I need a little more room for wires, which I can accomplish by making the whole thing ~2mm wider and about 2mm taller is the charging circuit. I'm .... when it comes to durability and getting that hole just so and getting it mounted and lined up is proving to be an issue, at least in that position. I'm gonna revisit the replaceable battery and start with a fresh design, I think I'll keep my RBA design, at least on the top but the case is going to change completely.

Lance_Wallen That is not a failure, that is a beginning step toward the perfection of your thoughts first full physical pulsations toward life eternal.

I am a "use metal (like solid silver) as much as can be done ONLY" sort(if I can afford it & I am more poor, than my floor.) & YET the thick durable body instantly says "H.igh E.nd M.achined M.anufactured E.ngineered D.esign" light & possibly affordable. The built in atty is not up my alley either, but I am a cheap poor old coot. I clearly see from your images that when you get it together, as you want it, it shall make your end users very happy with its essence on all levels.

I also like & notice it looks like it would stand firm & solidly flat being likely not wobbly in the slightest. Seems from looks to have a nice center of gravity. (Many mods fail there)

A must first start as A, on its way to becoming an AAA+++

 

[Lance_Wallen]

Thanks Mister E.

The delrin is my prototyping material, the walls are thick because I eventually plan on making this with hardwoods and i wanted ~1/8th inch wall so it'd be nice and sturdy.

 

[retird]

I'm sure you will get it worked out......

 

[Lance_Wallen]

I made some adjustments to the design to get this prototype working but it also taught me a lot of stuff that I'm applying to the v0.2

 

[retird]

That's good to hear... the dna20 is in the planning stage here so i'm building another DNA now..

so how is the rba working out?..

 

[MadmanMacguyver]

Lance...that is excellent for someone w no Previous CNC exp...call it a learning experience...the fact that you had the forethought to come in and check on you work despite its long runtime is a plus...I'm sure most would get bored after 30 min and not come back till the next day...


Me well I would not be able to help myself...I would have sat thru the whole thing and fogged the room w vape the entire time...lol....

 

[Lance_Wallen]

yeah, when I run the machine I spend the majority of the run time watching it. I'll vacuum up the chips, use a dental pick to pull stubborn bits out of grooves while it runs, etc. I'll baby that machine for the first year I'm sure.

 

[MadmanMacguyver]

its worth it...money saved in repairs is money earned...let alone ya also save in catching mistakes in cuts before they become irreparable...saving cost in material...

 

[Boden]

Interesting

Lance,
I'm looking for a supply of loose female 510 connectors for some mods I'm building for myself. Any vendors you know of sell em?

Thanks,
Boden

 

[jimbalny]

Nice work so far! I like what you did with the edges, slick

 

[Lance_Wallen]

loose 510 connectors? I think Madvapes sells em.
