The max ''body'' dia of the coupling is 2" which means only a 1/2" wall.

The material is our EN24 T which I think?? = your 4340 prehard.

Coupling on a machine run by semi skilled + labour,..... AKA they don't break much;)

1/2" thread, and I'm concerned about wear,..... so do I go 13 tpi or 20 tpi?

Thanking you for your time.

Several individuals have them for sale locally. Trying to decide on the electric type or the propane fueled type. The small electrics seem to fill my size requirements better, but the battery life and replacement is a concern. Seems most of the batteries cost well into the $1000.00 mark. In general is anyone using the electric (battery powered) type or is the propane type the way to go... ]]> General New gearhead http://www.practicalmachinist.com/vb/showthread.php?t=192796 http://www.practicalmachinist.com/vb/showthread.php?t=192792&goto=newpost Fri, 20 Nov 2009 18:36:57 GMT Sorry for creating another thread but needed one specifically for kiln setup questions.

I can get a pretty basic kiln locally for pretty cheap. That just leaves a better control situation. I find these little controllers on egay that are cheap but they do not run a variable frequency to the heating elements. Is that how even the good ones work? Just keep kicking a contactor in and out and this is all controlled by the digital PID system with a thermocouple input?

I remember reading in my other post that a better thermocouple system may be needed and possibly one just to read direct metal readings. I am really just looking for something cheap and small to give it a go on some tests to see what I can do and can't do. I am looking to run approx 500-1000in3 of material in it at a time. I am really just wondering if these little kilns lack the power to get things up to temp in a reasonable amount of time. I am sure if I can prove things out, I will just buy a real heat treat oven but would still be nice to do small lots quickly when needed.

I am primarily targeting low alloy and tool steels. Specifically 4140, 4340, 8620, A2, etc. ]]> General New viper http://www.practicalmachinist.com/vb/showthread.php?t=192792 http://www.practicalmachinist.com/vb/showthread.php?t=192789&goto=newpost Fri, 20 Nov 2009 17:51:17 GMT Hi guys.

I just discovered someone who sells new gear sets

for the Arboga E135. It may fit other models also.

(I don't know if you have a spare parts problem)

The advert I found is on a Swedish buy/sell website.

If wanted I might be able to establish contact (send PM).

(no - I haven't the slightest idea about who it is)

I am away from my shop for the holiday and would like to purchase a new starter for my Nichols mill and have it arrive before I return so that I can promptly finish a batch of parts. However, I forgot to write down what voltage the Allen-Bradley operator control (start/stop) unit uses to energize the magnetic starter. 24v? Any help would be greatly appreciated.

Thanks!

Short version: I bought an Emco V13 lathe in august, it was transported by "Road Runner Transportation Services" who as part of their delivery service ran a forklift into it, basically totaling it. They've dragged things out for months. Their latest offer is that they will pay me $140. Given that the lathe cost $2600 and shipping was around $700 this is disgusting.

There's no abiguity: they destroyed a good quality piece of equipment and are too dishonest to do the right thing. I'm going to have to sue them to straighten this out, which is a big waste of time.

I'd recommend avoiding them at all cost.

On that note: what freight companies do people recommend? I'll be buying some more equipment and would like to avoid surprises.


Here's some photos of the damage when it was delivered that I'd posted previously.

In the shrink wrap, speed knob, crosslide knob, plexiglass and lateral wheel broken:


Cross slide knob and the broken lateral wheel in the shrink wrap, indicating it occured after packing:


Fresh break: no oil:


You can see where it was rammed: the skirt is bent in, and the two parallel lines give the fingerprint of the object (forklift or was it in a van perhaps and hit the corner of something multiple times?):



Another view:


You can see the pallet is cracked too, giving a rough idea of the scope of the impact:


Broken plexiglass, bent rod holding it:


Unwrapped view:


Closer of the cross slide --- a very disturbing thing is that the knob was impacted heavily enough to damage the covering and likely the mechanism it covered:

I'm working on a new 18/8 stainless steel bottle design. I've got the CAD model with dimensions. I'd like to get an estimate as to the cost of manufacturing a new bottle design. can anyone give me a ball park figure as to the cost of manufacturing a new bottle? I'd probably try to get 3000 units with simple paint designs. Obviously china is a common manufacturer; are USA manufacturers competitive in price?

Any advice would be appreciated.
