Excellent, just got that done. Thanks

It's an old Curtis from 1942. Wondering what is the purpose of the 1/4" copper line running to/from the crankcase? The opposite end is now unattached and was probably associated with the original unloader system. Should I cap it off or leave it open like a breather?

Maybe this pic will give some needed detail. It's the routing of the tubing that I'm unsure of.

Can anyone at all help me with the correct routing of the copper tubing that runs up to the unloader valve on this model 95? I'm about ready to get the unit wired up and I'm uncertain since the fittings were broken off when I purchased the unit.

So "time in pipe" has a major affect on the cooling. Kind of like "time in grade" has a major affect on military pay............;)

Restating my question a differently: Can I run 1" diameter black pipe a lesser number of feet than 1/2" black pipe and get the same affect in removing condensation? Let's say I run 30' of 1" - would it equal 50' of 1/2?? To go from there............ would 20' of 2" accomplish the same??

That seems contrary to other posts, like suggesting you use the largest line right off the compressor to increase efficiency. Isn't there more surface area in a 2" pipe to help cool the incoming air?

Unfortunately 20' lengths won't work in the space I'm working with and that's why I'd like to see if a large diameter pipe would make a difference regarding total running footage.

I'm about to install air compressor lines in my shop and I've read a great many of the threads on the subject but one thing still eludes me. What affect does header pipe size have on the total footage of air piping? Since I'll be doing considerable sand blasting I want the remove the great...

I've got one of these that's in VG shape in the building I'm renting for my retirement shop building. Unfortunately the natural gas has been turned off to the building but since it doesn't get too cold in SC for very long (if at all......) I'd like to just put a large propane bottle outside for...

Thanks for the information. Yesterday I was surprised to find a company that actually had a parts breakdown on a model 95. It was for a model "F" but very similar. It wasn't anywhere to scale and not a great image so I can't decipher how long the brass pushrods were. He was nice enough to...

I'm in the process of getting a 1942 Curtis model 95 up and running. Not too much info is available on this model - I've asked all the large parts suppliers and Curtis. Right now I looking for some direction on how to rebuild the top diaphragm assemblies. I've found some rubber diaphragm from...

While not brand new, Hobart has refurbished 140's for 399.99 here: http://www.hobartweldshop.com/servlet/the-133/refurbished-welders/Detail I'm going to pick one up next month when money allows...................

BTW, u can see the pressure relief valve just laying there on the unit. It broke off and belongs on the fitting to the left of it. It's since been installed.
