All, I just read my last post and I want to apologize to everyone here, especially Balu. I'm just a hard-headed, opinionated, old man who DOES...
Good deal, Balu. We're fine. And I love to brainstorm... but, unlike the deep pockets we have to work with in industry, we all have different...
Balu, Not to argue, I've got to speak out of my own head/heart/experience here... it's all I've got. It's okay to disagree... I'll respect you...
Ya know... any respectable CNC owner ought to have a 3d printer or two laying around anyway IMHO... ;):rolleyes:
Here's something I thought about when I was playing with this before. There are all kinds of tiny beads used in fly-tying (which I love to do) for...
YES, yes, yes! Build a foam cutter just to experiment with. And Thurmond's idea for a hand-held version is really starting to grow on me. This...
That actually sounds feasible, Balu. I played around a bit with eliminating the bearing altogether... making a very small offset hole in the...
Sounds really neat, Thurmond, but I'm having a little difficulty picturing your cutter and the pocketing operations you are doing. Any way you can...
Balu, Flywheel center to guide throat is about 2.25" (57 mm) on the foam cutter pictured a couple of posts above and runs fine. Others I have...
A hand-held/guided model! Why am I thinking of a sabre-saw? Or, a router? I suppose there's a place for a portable model that could run along a...
Here’s where I am with my current foam cutter. I’ve incorporated Karl Tinsley’s foam cutter mount for HicWic’s MPCNC universal mounting system...
Sam, You need a bit of slop, needle in guide, I think. HOW sloppy? I don't really know but there's significant friction-heating taking place in...
Oh, happy day! Lowes had MIG tips... 0.035" (0.9mm) card of 10 tips for less than $7! They ought to be perfect. I've got to print Karl's...
Outstanding, Thurmond. I actually used 0.025" MIG-wire for my first versions. I'm not a welder so really didn't know about the tips that are...
Sounds great, Thurmond. I always love it when things just "fall into place" like that. Looks like all you'll have to counter-balance is the...
Sam, I know you said you ordered one but one of the best deals going on 3d printers IMHO is this Folger Tech 2020 (all-aluminum frame) Prusa I3...
Sam, I'm not sure about the scraping action you mention... there is virtually no debris generated if the needle is pointed properly. That's...
Looking good, Thurmond. It'll be interesting to see how you balance it... and how/where you mount the bearing. A good source of small bearings is...
For those that don't have a login on the Phlatforum... a walk down memory lane. The original foam cutter was an Intel CPU fan from a PC... with...
I see you made it over here... welcome, Thurmond. Speaking of power... I'm turning 8000 rpm or so (enough for nice cuts at 600 mm/min) on the...
