just get the fastest processor you can, there are some good websites on how Solidworks actually works within a computer. Perhaps things have changed, but what I learned a few years ago was the damn program uses a single CPU core - so the only way to make it run faster is speed up the core...

I've had a 17" Dell Precision M6500 for about 6 years now. It's a good solid machine, needs to be replaced now due as it's too slow for large Solidworks assemblies etc. I think it will last forever for any other application, it really is a well made machine. I was in India when the Power Supply...

Arguy, My guess is that a screw will not open the hole, it will just break off... Hardcoat is really hard, and it is more ceramic in nature than mechanical, it's very difficult to get it to yield, it will crack before it stretches. I will check out this OSG company for taps, thanks for the tips.

thanks for the links prdave00. I will check them out. My problem is we get the parts made by an outside machine shop, and they never cut the threads very deep, and after it's anodized - the thread entry isn't as far as I would like. We only make 'onesies - twosies' and that's why I was looking...

Just to wrap this thread up, I'll finish it. The boss's experience was 30+ years ago, perhaps they didn't have 2-piece ferrules back then, or was using some other brand, although he is definite it was Swagelok, but like a description like Band-Aid will cover many brands..could be something like...

Hi, We do a lot of Hard Coat Anodizing of Aluminum Parts, Mill Spec Mil-A-8625 Type III. My question is, as the anodizing builds up the surface of the material, in our case about 0.0015" on each surface, are there over-sized taps available to cut the threads, so after plating, the thread will...

Can hardly remember the last time I used a flared fitting? ...but you are generally restricted to the softer, malleable alloys? I think if you flared stainless steel tubing - you would just get a cracked end? Anyway - thats the value of these forums, you never know what folks will come up...

I'm not sure if I got a wrap over the knuckles for mentioning the brand name Swagelok. This post wasn't supposed to recommend or defame Swagelok - I used their name as they are one of the biggest names in the business - like 'Band-Aid' is for sticking plasters... So my question is open to any...

Missed out on the critical information - the material of the tubing, we use 316 Stainless Steel tubing. Interesting point from Icecool, about leaking under vacuum which sort of backs my point of higher pressures assisting to lock the assembly together - the tube reacting under system pressure...

I've used a lot of Swaglok fittings over the years and really never had a problem, always using a tube cutter, and always marking the fitting at finger tight, and doing the standard 1 1/4 turn tightening procedure. Always use an appropriate tube wall thickness to the tube diameter. e.g 0.035"...

There are a few posts on this topic, but haven't seen any definitive answers, so just seeing if there are any opinions out there. I am making a gas system, and trying to size the tubing from a Mass Flow Controller (MFC) to a Burner where Oxygen and a Fuel Gas (methane) will be mixed and burnt...

Thanks UncleSyd! I will look into the nano-lube product, I have a lot of interest in dry lube at the moment. There are so many areas where wet lubes are limited by their wet properties. Tommo

Thanks Plasgears, That is extremely interesting, I have never heard of this before - but searching the web has indicated that this is indeed used as a high temp lubricant. Does the "milk of magnesia" form a powdery, slippery coating? Is it cleaner than graphite? Thanks for a most interesting...

Thanks Russell, Our new machines will use the Lee Control Linear Pillow Blocks, we are looking forward to the trial results. Very simple idea, someone is making a good profit on those units! The linear bearings are not suitable for us as they need more power to drive, as the co-efficient of...

Thanks UncleSyd, I have lodged an inquiry with one of the companies you mention. You gave me some excellent references! I would love to read some if anyone else had had experience with ball bushings and dry-lubing. Thanks Tommo
