Re: Best flooring option for a welding/fabrication shop?

The trick for a shop/garage floor finish is to know when to quit finishing. Basically a trowel pass or two short of a hard shine. Done right it will be durable, sweepable but not slippery under normal circumstances. ;)

Re: Deciding right rating for earth clamps

I have a 300A Magswitch on a 250A mig that never gets warm. Get the one with the cooling fins as the body is a one part casting from the wire lug to the base. The 2 part, non finned style that's bolted together can corrode between the parts, short a bit and get hot which requires occasionally taking...

Re: Upgrading my trailer to A-frame design

By extending the sides you will be effectively adding some weight to the tongue anyway as the majority of the added material will be ahead of the axel with no gain at the tailgate. If you haven't already spend a couple extra $ on a wheeled jack. Much easier to move around. :D

Re: Upgrading my trailer to A-frame design

The reason why I wanted to possibly add the A-frame (or replace it with) is the side-to-side wiggle I find with heavier load (but no more than 600 lbs I haul most of the time). Like mentioned above, wiggling side-to-side could be an indication of a couple things. It may be that the trailer is loade...

Re: Sandblasting at home

My big shop compressor is a full 5hp, 60 gal tank, rated just over 20cfm at about 100psi.( Don't remember exact figures) Running my similar pot blaster it will maintain about 100psi running continuously once the pressure drops to kick in. Guess that would be the FAD! :?

Re: Flux-core with a Millermatic 35?

This is using Outershield Flux Core ( not gasless) and a 15ft work lead. Tried it with gassless and feed was a bit erratic...

Re: What’s best way to cut expanded metal?

I tend to agree with the circular saw and grinder. When I buy the stuff, I usually tell the place where I'm getting it from all my dimensions and have them Shear cut it. I then call it money well spent when it arrives. Couple of suppliers in my area wouldn't shear the heavier raised expanded metal ...

I got a similar blade in my Evolution 10" compound mitre saw and only used it for 1 test cut on 1"sqare tubing :o You need more teeth. Evolution and Diablo make good blades.

Re: Annular cutters?

Annular cutters work great. They start in size at 1/2”, so between 1/2 and 1” you won’t get 6-8, but you can get them in 1/2, 9/16, 5/8, 3/4 and 1” that I know of. You need to be aware that they have a cut depth due to the length of their “cup”. And they do create a “plug” like a hole saw. Most hav...

It was run by a pto hookup and the amperage was adjusted with the tractor throttle. At that time blacksmiths were...

Quickest way to knock teeth off of a dry cut blade is to contact the material at under the rated rpm. Don't ask! :oops:

Re: 3/4" plate weld.

Mild steel won't benefit from preheat above room temp. Your power source has enough grunt for stacked smaller multi passes. Your outer shield is going to give good peno. Given one side is only 1/4" you can't go to hot on it. Focus more to the 3/4", stay with your 035, give it plenty if gr...

Can't speak for the 8in blades but I have had very good service from both the Evolution and Diablo 14in blades. As too how many times they can be sharpened that depends on how badly the blade is beat up. I normally get 5-6 sharpenings before the blade is worn out for example. On the chop saw busted ...
