I was picking up a used Wissota grinder the other day and the gentleman also had a vise for sale for a price too good to pass up. I am not familiar with thew manufacturer, nor can I find any information about the vise or its manufacturer. Overall, it is a fairly nice vise. It does not quite...

This is not what anyone where is trying to imply. One must be careful when adding heat to structural or threaded components. Depending on what state the component came from the factory in as well as its carbon content, serious metallurgical changes can undergo when it is heated. Something...

This is only partially correct. If the metal was hardened at all and was heated enough then allowed to air cool, It will basically be annealed and the hardness will be lost. Both time and temperature are critical with heat treatment. Molecular changes, unseen to the eye can have profound...

I have one, though I have not used it much yet, I have enjoyed it each time it has been used. I bought mine off of Craigslist for around $200 which is considerably less than the list price. Mine is kind of an odd ball model suited for light industrial use rather than homeowner use...

McMaster Carr sells very nice insert bits. A few weeks back when I bought from them, they were Zephyr brand bits, which I believe is the OEM for Snap On. The price was quite good as well.

Even if one does not care about OSHA since it does not apply to private non commercial garages ASME references PVC and CPVC in their pressure piping code. From ASNI/ASME B31.1 A323.4.2 Specific Requirements 3. PVC and CPVC shall not be used in compressed air or other compressed gas service...

I am a fan of Weld-Tec's line of torches. They are solid and best of all they are not too bad on price compared to the weldcraft torches. A 20 series torch will be smaller than an 18 series torch but will only be rated for 250 amps. Bear in mind this is a continuous operation rating, so...

I also am a happy owner of an older Syncrowave 250 with a water cooled torch setup. My father owns a Syncro 180 with an air cooled torch. Either machine can make competent welds, but after using the water cooled setup for a while, the air cooled torch feels stiff and clumsy. The small size of...

I am also an owner of an S-4 and have been in the process of restoring it. Mine has what I think is the complete switch assembly, but all of the wiring from the switch to the lamp and the lamp itself is missing. Here is a picture of the switch assembly (at least what I have) all put together...

Very nice build. When I first saw the picture of John Troxel's car I knew something looked familiar, but I just could not place it. I looked into it a little more and I think I know why. About 5-6 years ago when I was working a summer internship in Kansas City, one of my good friends from...

Nice setup. I have a Syncrowave 250 as well and when I bought it the water cooler was sitting on top of the welder. This was awkward due to the lifting lug and the possibility for a leak to end up in the welder. Does your setup with so much weight up top feel stable? I was contemplating...

One thing to consider about the everlast suggestion. On their site it is listed at about $1600 without a watercooler and with a torch that most say needs to be changed. Watercoolers are quite expensive and fully prepping out a torch with all the accessories and spare consumables is also not...

First I wanted to thank you for this inspirational thread. I have been reading on it now since it first started, but never got around to commenting. When I saw your image of the charger, I knew it looked familiar, but could not place it. Once you showed the image from the Towing and Recovery...

It is also not true in the power industry with boiler tubes, condenser tubes, or heater tubes. In general the biggest difference in pipe vs tube is how it is measured (OD vs ID):thumbup:

+1 But what happens quite often is you are constrained by available space and are forced to load bolts in shear loading. This is especially prevalent in things such as suspension connections and other moving parts. By no means should the bolt ever be the "pivot" of the suspension. It is the...

I also was in FSAE and seem to remember something about disc brake hats failing. I will dig through some of my material and try to find an answer. I do remember that the choice of hardware in that application is critical. Use the best bolts money can buy, avoid stainless, and ensure that no...

+1 The NEC makes no exclusion for how the welder is used when a cable is specified to feed it. Most newer welders have an Ieff value on the name plate, which is the value to use when sizing cables. This takes into account the maximum current as well as the duty cycle of the welder. A cable...

This thread is quite timely. I was just trying to figure out what to use as a power source for some small electrolysis work. McMaster Carr has some small plug in transformers that output 12 vDC up to around 2A. I am not sure if something like this has much circuitry to sense what it is...

Very clever. For the slope, you can put the horizontal leg of the PVC in the oven for a little bit and then bend it lightly. The same thing can also be accomplished with a torch, but the risk of burning the surface increases.

Even among one spec such as an ACR bit there is a lot of variation. I have posted this picture here before, but in the following picture, from left to right the screwdrivers are as follows. Snap On Instinct #2 ACR Snap On #2 ACR bit A no name screwdriver with a licensed Phillips ACR tip You...
