Can't argue with that!

Couldn't you hire the best welder in town (to make a nice steel frame) for the money you're putting in the extrusion and epoxy?
Steve
Very nice Mike. I've had a spot welder on the to-do list for some time. So far I've been holding out for a 5kVA transformer, maybe I should go for a microwave. Yours does a nice job.

I set up LibreCAD and drew the basic figure. This imports (as a dxf) into F-engrave with no problems.
I have a drawing in Sketchup which consists of a fairly simple set of straight lines. I can export it as a bmp (free version).
When I import it into F-engrave, set for engraving, the single lines...
F-engrave works pretty nicely for v-carving. It is also free--at minimum you can learn what features are important before looking for software that has them.

I don't know much about fuel cells, but I'm pretty sure they are both expensive and fragile. I admit the idea of making your own is interesting. A hydrogen flame is not visible, take note.

Two details:
I connected my shop vac hose to the PVC by adding a layer of EPDM to the inside diameter of the PVC. The hose end is tapered, this thickness made a match.
Watch the EPDM and avoid...
It's cheap to try something crude but effective, admittedly I did this on a smaller scale.
I started with a continuous surface spoil board--MDO plywood, no T nuts. I installed a PVC shower drain in...
Great suggestion pippin, I'll try it.

Until I can afford a vacuum pump I'm using my shop vac. It works fine for things 2' on a side. For 1' square I need to reduce the cutting speed/depth i.e. the force applied to the work.
Plenty of...
What benefit would you get?
They're already hardened. They need lubrication--this and a dust cover will take care of oxidation.
Same with the ball screws.
These are precision designed and made...
Here is a good explanation:

I highly recommend f-engrave, free and works really well:

A long thread:...
Scorch, my apologies. The file I sent was the updated file from my Windows laptop, where it was created. I moved it to my Linux box in the shop, copying a bunch of files from the USB drive. I said...
I'm using my shop vac as a vacuum holddown--it works pretty good, but I need to take lighter cuts to keep from pushing the work around.
This current project is small, about 8x8", and doing a test...
Thanks, I should have tried it out. Very clear now.
Somehow I'm not understanding Flip Normals vs Add Box under V-Carve Settings.
I'm doing inlay, so on the prismatic cut side Add Box seems recommended from the V-Carve Settings form, but I don't know...
I bet it gets quieter when you balance with the caps.

Phosphoric acid is a much better choice than Hydrochloric. Phosphoric (as stated by others) leaves a layer of iron phosphate behind, which provides mild rust resistance by itself and paint adheres...
I don't know Ron, those voltages aren't off by significant amounts. Maybe something other than voltage is going on. Not sure what to suggest.
If it was a voltage balance issue, I would balance with...
What keeps the needle from falling out if you raise Z?
This looks like a huge improvement over the three bearing approach.

Ask the people who make the software you like. They should have an easy way to transfer the license to a new computer. No point in learning new software if you like what you have.
Steve
Did you check to see if the steel is hardened? An angle bracket sounds likely to be.
Steve
I'm using LPS2, which is supposed to leave behind a waxy film. Way oil had not occurred to me, it will probably do a better job.
Both gas struts and metal springs have the same force/distance...
Thanks Andrew. Poking at it this afternoon I was coming to the conclusion that the weight had a lot to do with it. I ran two tests (stepconf in Linuxcnc) +/-0.5", 10ips screeched after a couple of...
I made my cnc router with 80/20 linear rails--shaped plastic blocks that fit in the 80/20 rail. It seems to work fine on X and Y. I have had a bit of slop in lettering, so a small entry divot gets...
We covered the whole ceiling. The room was maybe 12x12 feet, used foam 18x12 feet, 1" thick. Easier to do in a small enclosure.
Steve
There must be pages out there discussing sound deadening enclosures, but I don't have any bookmarked.
The key thing (besides open cell) you already know--maximize the surface area to maximize...
Be sure to get the right sort of foam. You want open cell foam, this will work much better than closed cell.
