I was planning on using a 1.5mm slit. Why use a baseplate > than 1.5mm in this case?

bigben2k · 03-31-2003, 11:19 AM

With the slit, 1.5 ought to work well.

yea an XY table and a 10mm 2 flute endmill, damn thing vibrated so much it eventually chipped a peice off the endmill.

Update:

I found a way to modify the drill press so that I can adjust the height z axis with a bolt. I bought a shitty (pun intended) xy table and a 5mm 4 flute endmill. I am using a 5mm endmill because i'm milling 2.5mm at a time. This is what I did:

hara · 04-01-2003, 01:43 PM

This is the milling

hara · 04-01-2003, 01:44 PM

Currently I'm making a 10mm copper bar 6.5mm. It takes quite a while

when i did that, muhaha, that's the result i got.

At least on my drill press, that's not a good method to use. i got a crappy result using that method when i tried, so i had to find a much much more accurate way. If i only had a digital camera!!!

Machining the base is now ready. I'll post pics soon.

hara · 04-03-2003, 11:16 AM

The tools used were a hacksaw, a vice and a triangular file (for the pointed fins). One could call this block a poor man's WW.

hara · 04-03-2003, 11:17 AM

This is the result. That is why it's called a shitblock, because the finish is shit:

hara · 04-03-2003, 11:19 AM

It is shitty. If only I had a CNC

hara · 04-03-2003, 11:21 AM

I even f-ed up the drillpress because the table was shitty

Hope that it can be fixed by welding (hint for balinju)

Another view

Any comments/flames/questions/suggestions please?

hara · 04-04-2003, 02:09 AM

How am i going to stick a copper top to this POS? I thought soldering maybe, but...what do I need? Blowtorch? 300W soldering IRON?

Check out how Bladerunner did it, at www.zerofanzone.co.uk

Ok, solved that problem. Next Problem: cutting a 1.5mm slot in 3mm of brass and a copper pipe. Any suggestions???:shrug: :shrug:

bigben2k · 04-04-2003, 09:24 AM

Just drill a series of holes, then file it into shape.

nicozeg · 04-04-2003, 09:53 AM

You need very close matching surface to get a good seal with solder, so better forget it and use a large silicone blob in all the seams. It's not the best looking but seems it don't worry in this case

Actually, I don't think that will be a problem. I won't be running 1000psi through this thing.

I don't have a file that's smaller than 1.5mm

hara · 04-06-2003, 08:47 AM

But I could use a hacksaw instead.

I bought some 3mm thick brass. I used brass because it is cheaper and stronger.

I designed a top for the Wb which is this:

hara · 04-06-2003, 08:51 AM

This is the brass and the copper base with soldered edges.

hara · 04-06-2003, 10:13 AM

Some progress, the top cut out of brass:

hara · 04-06-2003, 10:14 AM

The Microchannels can be seen through the slit. A question, what should I use to bond the top to the base? Silicone or some other epoxy?

hara · 04-06-2003, 01:38 PM

I get a feeling that nobody's interested
