Still a Tough Job, but Doable - Works on Steelcase Amia

As others have said, cylinder replacement is not a particularly easy task and varies quite a bit from one chair type to another.  The metal collars included provided a reasonably straightforward means of removing the old cylinder, but it still took me two attempts and a bit of swearing to get the job done.  Here are a few tips:

1.  Make the lower collar VERY TIGHT against the cylinder.  Otherwise, it will simply slide instead of pushing against the top collar.
2.  Be careful not to strip the allen nuts on the cylinder removal collars.  I used my drill to speed things up.  I got away with it, but very nearly ruined the nuts on my second attempt.
3.  Be sure the two collars are offset from one another (rotated >30 degrees on the cylinder).  Otherwise, the bolts used to push against the first collar will simply screw into the corresponding holes. :-)
4.  On my chair, the 2" diameter cylinder "shell" was difficult to remove from the base after separating the chair/cylinder from the base.  If you have this problem, take the base out to your workbench, put on your safety glasses, and give it a good whack on the bottom with a rubber mallet.  If this doesn't work, you may need to resort to something heavier.  Ultimately, I used a five pound sledge as a means of gentle persuasion.
5.  Be patient and take your time.  Do not expect this to be a five minute task.

Finally, one reviewer mentioned that this cylinder did not work with her Steelcase chair.  I'm not sure which model she had, but I have the Amia.  Other than the issues I mentioned above, it worked fine.

Overall, highly recommended ... and the disposable gloves are a nice addition.  Note that you WILL get greasy on this ride.

As it came this case was adequate for a matx/itx system.  I purchased 3 of these and had to mildly modify the case for each one of my projects.  In each project we had issues which required putting a piece of the case on a saw or a drill to modify it to fit our Motherboard or large PCIe video cards.  The last case  arrived without enough screws, 5 instead of the required 8 to anchor the motherboard in place.  It was much easier than starting with a blank slate of acrylic but far from plug and play.

It's pretty well put together but the amount of work I had to put in to get the iron into place was insane. My larger plane took me an hour or two of sharpening and scraping wood to get everything set up and this tiny thing took twice as long. Still, it works great now that I've got it all together.

The SATA ends of this cable are fine, but the Molex end is fairly difficult to use. The pins in the Molex style connector are not fixed in place firmly, so they wobble around, not staying straight as you try to plug the connector into the mating end from the power supply.

All four pins have to stay straight enough to each mate with its mating socket as you mate the connector with the mating power supply connector. If even one of the pins is misaligned, it keeps the connector from mating. With perseverance and patience, I was able to mate the connectors on about the twelfth attempt. Frustrating, but works fine when you finally get the connection made.

I wired a set of Outdoor Power over Ethernet HD network cameras with this cable. The cable is buried underground with runs of about 200 ft. Nine months on, all camearas continue to work without problems. Fitting the connectors was however a challenge: Removing the outer sheath is a chore (understandable given it's designed to protect the cable). The aluminum clad copper cables are very brittle and fracture easily - had to re-do several connections, Crimping is also difficult due to the cable thickness. On balance, I'm fairly satisfied given the price

To simplify the connection process, I switched to these EZ Connectors:&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Platinum-Tools-100010C-EZ-RJ45-Cat-6-Connectors-Clamshell-50-Pieces/dp/B000FI9VU2/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Platinum Tools 100010C EZ-RJ45 Cat 6+ Connectors, Clamshell, 50-Pieces</a>&nbsp;they helped significantly

hard to install, but worth it if your good with a micro tip Weller solder iron.

Worked but took some effort to fit through the enclosure of the esi system i needed to hard line into.

Magnet could be a bit stronger, requires a lot of back and forth to get the tough stuff.

It works. I had to very lightly sand the shaft to get it to go into the barrel, but that means that thare was absolutely no play as I was cutting the threads.

Aluminum is a better choice than steel for this--steel would damage the rifling in the barrel if it fit with the proper tightness. If the fit is tight, the aluminum will deform before damaging the rifling.

I had no problem with the shaft bending. If you're torquing the die sideways while cutting threads, you're doing it wrong. Even if the die starts out straight, your cut will wander off-center if you don't consistently apply equal pressure to both handles of the die holder.

I don't know if this will help you cut threads accurate enough to mount a long suppressor without baffle strikes, but it's definitely good enough to thread a barrel for a flash hider or muzzle brake.

If it had a collet-style adjustment to ensure a tight fit I'd give it 5 stars. But coming slightly oversized and sanding to exact fit works reasonably well, especially for the price.

This one does not fit on my machine as easily as the one that came with the machine. However, with some real power-pushing I am able to get it attached and unattached. I just wish that I didn't have to work so hard at it.

Saw some other reviews that said the case would not work for the 400e electric saw without modification. I can tell you that the saw fits in the case without modification, there's just enough room to loop the electrical plug around without bending it too sharply, and the case closes just fine. It's not a perfect, molded fit, but I am happy with it as-is. I don't plan to modify mine. I was just looking to get the saw out of the elements away from kids, moisture, bugs, etc. and the stock solution works fine. There is also lots of room for extra blades, the adjustment tool, oil containers, etc. inside. I wouldn't necessarily recommend it for safety's sake, but the fit is even better if you cock the chain brake handle in the ready-to-saw position. Just be careful to release it when you first remove the saw from the case.........

I find it a tad bit difficult the remove bridge pins with this tool, but if you put the tool just right, it'll work. Just requires a bit of practice.

Some have noted that their tool is very tight: If you find the components difficult to get out, try using a small star tool (torx wrench) to adjust the case bolts to the tension that you desire.

Another recommendation -- when you get it, give the tool a good wipe down and then lube the joints with something like PB Blaster PB-50 or 3-in-1 oil. This will help smooth operation and might keep you from getting frustrated by tight tool fit that does improve as you break the tool in.

The PB was very effective for me so no bolt adjustments were needed, and the tools are easy to implement just using my fingers... except the blade which remains stiff. Since the blade is very sharp, I think it is best to remain somewhat tougher to get out in order to avoid unintentional opening.

This tool let me take a bunch of stuff out of my range bag -- three small screwdrivers, a shotgun choke tool, a knife, a small set of allen wrenches, one Glock punch and two star tools. While most of those items were in a ziploc bag, this tools freed up space and it looks a lot better coming out of the range bag than the ziploc bag did.

I definitely recommend this tool if you have a few moments to make tweaks like those noted above. Take care of the gear and it will take care of you.

Truthfully I was a little scared to tackle this project. I have worked on many computers before the parts became so small and the cables are ridiculous. Anyway I did a very sloppy taking off the old screen. I do not have a heat gun so I shoved a metal finger nail file under the old screen and pried up the edge far enough to break pieces off. I eventually broke off enough of the edge that I was able to remove large pieces of the screen. I carefully used a single edge razor blade to cut through some of the glue on the edges that held smaller pieces on. To finish removing the old glue I used cotton swabs and WD 40. The one thing the other reviews did not mention was how to connect the little ribbon cable. So here it is. I could see where the ribbon connected on the circuit board. There is a very small fastener on top of the cable. It has a little white piece of plastic over the cable. I pushed the plastic up a little and that allowed me to pull the cable out. When you push the new cable back in just push down on the plastic to lock it in place. Do not pull the little plastic away from the circuit board. You could break it. Just up and down like a switch. After everything was cleaned up and put together. It worked perfect! I did this to the Kurio 7S. The other reviews helped me a lot so read all of them.

It does its job, but there is definitely a lot of room for improvement. After reading some of the negative reviews about the part cracking under the weight of the dust collection hose, I can see how that might happen.  All Bosch has to do, is make this part out of a stronger material than the ABS, and there will probably never be an issue.  Until they do however, it's probably a good idea to keep as much stress off the hose connector as possible.

Strength issues are not my biggest gripe about this adapter.  I bought this, intending to use it with template routing, however the adapter won't fit on the PR011 plunge base, when the quick change template guide adapter (RA1126) attached to the sub base. Wanting to extract dust while template routing.... silly me.  I'll probably get out a bastard file and a nibbling tool, and find some way to make this work with the RA1126, but that should have been Bosch's job.  For template routing, I may have no choice but to replace the sub base that uses PC style guide bushings.

Took awhile to get it to do a thorough job, but works well if you take time to do it correctly.

Bought this as part of a solder kit, which included solder, the iron and this helper. I got it out and saw that it was well built, and looked to do the the job. After clamping my project to the arms, I noticed its quite tipsey, which makes it harder to work on, but not impossible. Depending on what your working on this might work out for you, however for a bigger board like mine doesnt seem to work very well.
