I tried to find them on Ebay, to no avail... Does anyone knows where I can find those? Thanks!

Additional gear reduction would put the speed of rotation in a more useful range. The higher speeds are totally useless. Thanks for the review.

I bought this unit and did not get the clip and carbon brush to allow the unit to give the ability to use the turntable for Welding. I've contacted vevor about this and am getting the runaround. They said it's a consumable they drop $60 off, and I then needed to find the brush and clip. I said no way either send the part or give me a return label and a full refund. I wouldn't have any idea where to buy the part and I'm assuming by there reply they don't offer replacement parts rendering it worthless in time. Bad business practice.

Will 3inch pipe fit?

I find these 2” wide squares too much bother to attach to the table. There’s a reason the cast iron versions have just one side. Getting the fixture bolt in between the sides and tightening it is a real hassle. Not impossible, obviously, but annoying. They do make 4” wide versions which are much easier to use, but take up a lot of room on the table. The main virtue of these is the cost, which is low. A 10” high precision machined cast iron version costs $120. Some others I have cost $168 and even more. I would like these if they were made from a thicker plate so it can have just one side. And if it were 0.500 thick it could be used with standard fixture bolts for either 5/8” holes or 16mm holes. The trick to getting these correct is to make sure all the parts are tightly held together before welding. The slightest amount of looseness will cause it to be out of square, just as in assembling the table. Just remember that there is no warrantee for straightness or squareness as that’s up to your ability to get them that way.

Do you have a link or ebay description for these. I would like to buy a couple to put together. Thanks. keep the videos coming.

The center of the slotted side could be adjusted by propping the ends and lightly hammering or pressing the center out until it measures flat. Same with the tip of the second square.

I just took the same model positioner out of the box and tried it with TIG pulse. I had the same issue with the speed controller. On lowest speed, it wasn't consistent and would stop some times. It didn't work on the lowest setting and on speed 2, I had the inconsistent rotation and stopping. The other big issue was the ground. It wasn't consistent and would arc on the plate as it moved, throwing sparks and debris every time the torch would pulse to a higher amp. I'm disappointed, but I can see why a good one is so expensive.

These are some really great points! I will be sure to look into the improvements you’ve suggested and make some videos sharing the results. Thank you for your support!

It looks to be a decent foundation for some improvements. I can imagine coming up with a better ground connection, for example. It could be brought down to a steel base plate that has pins that drop into the fixture table so that it is grounded as soon as it’s set on the table. Maybe a reduction gear on the drivetrain would make the speed control range more useful. As it is, it seems the slowest speed is faster than I’d want, especially if the radius of the pipe is large and the top speed is beyond anything useful for virtually all welds. It appears the drive motor is offset, so maybe a much smaller pinion gear on the motor’s shaft would be all that is needed to reduce the speed. Lastly, I wonder if replacing the foot switch with a variable resistor would allow variable speed while using it. Maybe a TIG pedal would work. Thank you for posting the video.

Great job with this project Assabet is very proud of you! Thanks,
