Here is another oddball tidbit about welding. Nearly all of my experience pertains to ASME pressure welds on boiler tubes. In the past people have broken the flux off of a stick welding electrode to use as a TIG filler material. On low alloy electrodes like E7018, this can work, but as the...

For the return spring you can go ahead and take it apart. The return spring housing should have threads cut into the body that mate with a bolt in the head casting. This bolt interacts with the threads and should make rewinding the spring in place an easy job. I restored one almost just like...

Using submerged arc strip cladding, the filler is not limited to round wire, but instead can be wide strips of material. This can easily be used to add a cladding of inconel, chemical, or wear resistant material to steel, sometimes in "beads" 2-3 inches wide. This used a tremendous amount of...

For the chevron seals on the main ram, the seals are preloaded independently of the rubber packings. The ram stop ring is threaded and is designed with 4 pin holes in the face used to tighten the stop ring against the chevron packings. After they are loaded, the packing rings can be installed...

After a brief pause on this project for the birth of our 3rd child, I was able to get back to work actually assembling the hydraulic unit. For the most part all of the parts only required cleaning without any real repairs aside from polishing every moving/sliding component. While starting the...

Search on McMaster Carr for "Telescoping Weld-Together Rails. https://www.mcmaster.com/weld-together-framing/telescoping-weld-together-rails/?SrchEntryWebPart_InpBox=telespar+tubing They have a selection of tubing both round and square sized to slide in each other. I have used on projects...

Here is what I measured so far on my jack, all the dimensions are based off the bore and cylinder measurements. Bear in mind there are some variations in the seal configurations on these, so you best bet would still be to take yours apart and cross reference dimensions. Also, I am not sure of...

That was kind of what I had in mind. I need to find some bit of material, preferable plastic that is large enough to slip over the ram and drill two small holes and place pins in it. The picture below shows the ram packings better. There metal piece in between the V packings and ring packings...

I am still confused by the pictures, I and some others can see them fine. I checked them on my work computer and it was like you described, not even a broken link or image symbol, just nothing. The pictures that you could not see, showed the packing arrangement, but no dimensions. I can try...

With all of the packings and seals removed from the hydraulic unit, there is no wonder the seal kits on these jacks are so expensive. There are so many sealing elements, but I guess the proof is that a 60+ year old jack was not leaking. I was terrified of not getting the packings back in the...

Odd, I can see the pictures from two different computers I checked it on. I wonder if anyone else can see them? Moving onto the hydraulic unit, I wanted to figure out the function of all the various ports and ball checks in the unit. The original paperwork was a big help, but some of the ports...

It has been a long time since I have checked back in with this thread I started. Ever since I bought this S-4 jack, I had always owned a "cheap" aluminum racing jack. That was a purchase I made when I was young and did not know much better, but it was always frustrating to me. I could not...

I use the ironclad loves in question at work. They are not used for welding, but for doing slag inspections on industrial boilers. The inspection doors are typically quite hot, but the real kicker is the radiant heat once the doors are open. I think the gloves do much better than standard...

I shot an s biner today with our material analyzer. It registered as 410 stainless steel, which is a martensitic grain structure stainless steel. This type of stainless can be hardened by quenching, unlike the 3xx series of austenitic stainless steels. I checked it with an impact harness tester...

I am not positive about carbon fiber, but for many composite materials like fiberglass and G-10 garrolite, water jet can be problematic. All the times I have tried garrolite, the water jet works great for parts of the cut, but will then de-laminate and bubble up the composite in other portions...
