There are strong opinions on what method should provide belt tension. There are basically 4 methods for this. a compression wire spring a extension (pull) spring on the back of the tension arm. I used this method on the No Weld Grinder. It works and a cheap door spring does it. a gas strut a...

We need to add an option for a spring tension arm so there will be 3 choices, wire spring, gas spring and pnuematic cylinder. It should go about here I think. I added a retainer spring "hump" just under the tracking mech. I also welded a 1" bolt to the top of the tool bar cage to hold in...

good trigger discipline

Metal prices are up 250% in the last 6 months but it still looks promising this will be competitive in price. I am still working on sourcing some parts so I haven't made much progress on a retail yet.

This is the pile of prototype builds. The creative process for me is messy. I will have to go through this pile later to see if I can salvage a complete frame or two. There are parts here from at least 4 different welders other than the one I am working. I started with one table and have...

The optional 12" vertical mount shown next to the "regular" size mount. Here on this proto build, you can see the regular size vertical mount in place. When you tilt it 90 degrees the motor would hit the bench so it has to be mounted on your work bench or tool bench so the motor can swing...

Next we weld the foot pads to the vertical arc bracket. Pretty easy. The foot pad is symmetrical so it doesn't matter which way it goes but the draft in the slot might make it easier to go on one way vs the other. Check your fit. Note the hammer to the right to get the tab to properly seat in...

Now we weld the main swivel brackets in place. Keep them square and note the orientation. It is easy to weld these in upside down. I did that and had to cut them out and flip them on an earlier build. Now we are going to weld some nuts to the main plate and the tool bar cage plate. It might...

Now lets weld the tool bar holder in place. The 5 pieces (main plate, cage plate and 3 tool holder parts) are all "dry" assembled and clamped in place. Don't be afraid to tap things with a hammer. If you weld much, you already know this. I am making sure things are perpendicular. This...

OK, time to weld. We will start with the tension arm and the swivel brackets. Keeping things square with a welding magnet. These things really suck as you think things are square and they aren't. Check it. Both are welded. Here is a view of the button weld. You are filling in the notch on...

A static tool rest will be included. It is simply some 1/2 plate welded to a 1.5” tool bar. This simple tool rest is probably good enough for most people but we will also have an adjustable tool rest. The optional adjustable tool rest is telescoping square tube welded in place with a...

The tension arm has 2 small swivel brackets to weld onto the wheel side. These brackets will hold the swivel tracking block. The swivel tracking block - not pictured- hold the tracking wheel and angle the tracking wheel for belt tracking. To the right of the tension arm is the slack belt and...

Now we weld the swivel brackets to the main plate. Keep things square please. The 1/2” hole near the bottom is the actual pivot point. The arc will allow a retaining bolt to be tightened but really just acts like a guide when tilting. These are welded to the motor side just under the (already...

Now we are going to weld some nuts to the main plate and to the cage plate. These are used to hold tool bars in place. We are going to wel 4ea 1/2-13 nuts to the main plate on the wheel side. You will not use all of these at the same time as the handle “knobs” interfere with each other. Weld...

This is the main plate. Everything builds off this. It is 1/4” plate. Your first weld will be the tool arm sockets. You will weld 3ea tool bar holders and cage plate to the main plate. Here you can see one of the holders in a slot. All 3 holders are in place. These are button welded on the...

This is what part of the kit will look like. Not pictured are: wheels, fasteners, tension system (3 choices are being developed; a spring, a gas strut and pneumatic) and optional adjustable work rest. You should be able to make out the tabs and slots. Note there are two vertical mounts. The...

This is a placeholder thread for information and assembly of the U Weld Grinder Kit. Overview: the U Weld grinder kit will be a full 2x72” grinder that is welded/assembled by the customer. No Price or release date has been set. (but soon) Having said that, the idea here is to put out a...

Every grinder we have in the shop has a glass platen. Using Fireplace Glass - borosilicate- Pyroceram- ceramic- ….. instead of a metal faced platen will reduce friction and heat giving you longer touch time before dunking in water. That alone is worth it as it gives you more time to stay in a...

I hear ya….we have an Uber grinder here in the shop that uses pneumatic and we always have the compressor on so the air thing isn‘t an issue. I didn’t care for the concept myself when we got it but the more I use it the more I like it. I will also have a gas spring option, I just haven’t got...

the grinder kit project is moving along. the concept is to use our CNC plasma table to cut out grinder parts. They will fit together using tab and slot and then welded. I have an Uber grinder with pneumatic tension and really like it so I am adding that. I need to find a source for gas type...
