I think the first step is decide on which plan you'll build first.



Then you might not be happy with the smaller tables and Dremel/Rotozip type spindles. Think about the 25" x 37" dual...

Hi,



I'm just starting my Solyslva build. Upgrading the 5/16-18 NC screws to 1/2 - 10 Acme came up for me, too. It's sure the most cost effective upgrade for improved accuracy, speed and...

These are work examples from David Steele's site:

1/64" to 1/100" accuracy is reasonable to...

I've just started building David's 37.5" x 26.5" machine from plans I ordered last year. I've used high end commercial CNC routers and lasers for years. We rented hourly time on these for our own...

Ian,

Isn't being on specification and time with contracted product the most important part? Or am I missing something? :confused:



If someone is substituting below standard materials to...

Sometimes. There is a widespread myth that ISO cert somehow makes faceless long distance transactions 'safer'. I think it plays a supporting role in the Legend of the Benefits of International...

Ian,

Unfortunately I've never been to Australia, so I can't speak to 'backyard' conditions there. I still want to go Down Under some day.



A friend of mine here in Florida ran a one man...

Ian,

I understood what you meant is 'meets or exceeds specification'.

But ISO 9001 has nothing to do with that. It's another advertising scam like 'free trade' and 'paper money'. The...

They merely moved the patterns and production to mainland China. The 9x20s and 12x36s I've looked at in Harbor Freight are still full of casting sand and crap machining. Their basic methods -...

Ian,

>>The other thing is it takes a lot of input in material and machinery to put the expertise to work, otherwise you cut corners to make it pay and end up making someone else pay.<<

You've...

Ian,

>>but it is also prone to blow holes and rough inclusions, really crap stuff.<<

Mostly that's a sign of hydrogen porosity, which almost always arises from moisture. Preheating the scrap,...

Kipper,

You summed it up. Never underestimate the combined power of ignorance and laziness. It exercises more force than the biggest lathes or mills imaginable.

I can't imagine a better...

I see.

Looks like we can add round trip airfare and hotel accomodation in Wuhan, plus shipping from Wuhan, to the price of this low cost quality laser. Plus the time needed.

LaseriPro and...

My opinion.

We've been using small CNC lasers in this class to cut plastic parts for architectural models for 6 years now.

I have yet to see any Universal or LaseriPro machine that didn't...

I hope he continues on and works through the lost foam problems.

1. I noticed he says he used premixed joint compound. All the premixed joint compounds I've looked at contain latex. Better get...

Craig,

That's one good reason for using commercial refractory if you have the cash to invest. Even more important if you aren't in it for 'fun'. A lot of fellows would like to do something else...

Far from it. Even real chars differ wildly in energy content. It's an interesting field with a lot of underlying science. And it's doable well locally at very little cost and seemingly simple...

[QUOTE=nikolatesla20]Well to be honest I would not know for sure, but I would not doubt it, depending on the type of charcoal used. Aluminum is really a low melting point metal, and 4 lbs of charcoal...

Oh really? So why has so much production work seemed to slip away to their home countries? Did they perhaps take more than they added? Who if not those Indian grad students have been setting up...

Nothing will be done by people sitting around wringing their hands and saying 'we can't win'. This is for certain.

ps

Moondog,

The Data-Cut plan book states that for machines longer than 49" you need to seriously consider using a pair of leadscrews/ballscrews mounted on the sides, rather than the specified...

Hi,

After a month of research last October-November I bought the Data Cut plans from Chris Lubke. He's employed full time as a CNC operator and is extremely knowledgeable in the CNC subject....

We've been successfully using several local award/trophy shops to do laser cutting for architectural model parts from various plastics, and also cardstock and light woods. Many of the better trophy...
