Description

The 84 Engineering plunge platens make grinding plunge lines and rounded corners simple and repeatable. These platens use a 6mm, 19mm or 25mm small wheel, which reduces friction and increases belt life. They are designed to provide the best finish on knives, with minimal gap between the roller and radiused edge of the platen. This ensures that there is no discernible transition between the wheel and 215mm flat platen, reducing the need for hand sanding.

The 6mm plunge platen is recommended for thinner blades, while the 19mm is recommended for integral bolster style blades and the 25mm for larger shaping. These plunge platens can be easily swapped out with the included platen on Shop Mate 48" or Shop Master 72" belt grinders, using the standard tooling arms. They can also be used with the included small wheel arm on a Gibson 72" grinder. The spigot can be mounted on either side of the plunge platen, allowing it to be used with the platen facing up or down depending on the application or preference.

Cheaper than the supply house.
Size: 42'' x 28''
I used black pipe similar to this to build some shelves in my man cave. I went looking to build a studio desk and found that Lowe's wanted $8 per floor flange (~$96 just for flanges and not including the pipe, tees, or the other fittings). Even supply house dot com wanted $4 per flange (~$48, but was still missing the other parts AND they didn't offer them because of supply chain issues). For about $65, this was a great buy. Yes everything is greasy. This will be the case regardless of where you buy it. I used some gloves, shop towels, and acetone and it cleaned up easily. For a top, I used a pre-made countertop from Lowe's (~$100) and a 1x4 piece of poplar I had sitting around.

Pipes don't assemble square, nice stand though.
Size: 42'' x 28''
These arent standard SCH40 pipe for starters. Significantly lighter. Easier to move around and sturdy enough to support a table, but this isnt pipe. As such, when I threaded it together, it wasn't square. I was able to flatten it mostly, but I had to use a clamp to bend the assembled piping to sguare so it would attach to the table runners. It's fine, but it surprised me. It looks nice, and it provides plenty of support for the table. All good. Several folks complained that the pipes are oily. They are supposed to be to prevent rust. I wiped them down with a few cleaner wipes, and they are fine. Be aware that this doesn't come with instructions or the wood screws you may need for your table top.

Sturdy & Tuff going on 6 months +
Size: 28'' x 14'', Size: 28'' x 14''
I mounted a thick heavy piece of butcher block to these legs and made a desk. Easy to assemble and install. Mark the holes, pre drill pilot holes and screw them in. I will say I knew they were going to be greasy out of the box. They grease them in the factory to prevent rusting so just wipe them off with an old rag and your good to go. They haven’t felt wobbly or anything like that and butcher block is pretty heavy. I have to say I love them and much cheaper than buying from the hardware store. I’m thinking about building a second one and I would definitely purchase again. Again very sturdy and easy to assemble. People mad about the grease need to realize it’s done as an anti rust measure and it wipes right off and zero rust thus far.

Absolutely not.
Size: 28'' x 14'', Size: 28'' x 14''
Truly terrible product. If you're wanting extreme DIY, aka cleaning it repeatedly, no instructions, and still not impressive quality, this is the item for you. After much time spent trying to remove the nasty oily substance all over the pipes and some sort of weird dirt coming out of the pipes as well, it still hadn't fully come off. When cleaning off the grease, it also took the color off of the item and created a weird, lined look on the pipes, like it was some legit oil rubbed crud on it, instead of paint to look oil rubbed. There is also what appears to be rust on some of the pieces. If someone actually wanted to use the desk and actually bumped into one of the pipes, it would without doubt leave oily residue on clothing. Pictures included of the box without pieces in it as it beautifully captures just how much crud was all over. 100% do not recommend and would give zero stars if it was allowed, but alas.
