Basement Shop Progress Pics 2008.09.02

Finally got the cyclone mounted up and it runs fine in its new position. This time I used the stand - I looked into wall mounting but didn't feel comfortable with the type anchors I would need in the block wall. An alternative would be to build a torsion box wall for the unit to attach to, but after calculating the amount of room it would also take, it made better sense to just use the Grizzly-made stand.

Note the cut-out in the ceiling to clear the motor housing. It's wrapped in insulation to cut-down on noise and I was careful to isolate the entire unit from touching the walls or ceiling, to help cut-down on vibration. It's still loud, but mostly from the on-rush of air, rather than from the unit itself.

You might wonder how I got this guy assembled - normally you would put together the bulk of the cyclone on the stand on its side, then tilt it up into position (the manual recommends 3 people). I didn't have that luxury both in man-power and in ceiling height. I noodled this one for a while before coming up with a method that worked. I first built the top of the stand and attached the cone and impeller housing before laying on its side. Next I built a wood platform with castors that fit inside the stand. I then tilted up the whole unit until it stood on the wood stand and set the motor and impeller on top, attaching with the supplied bolts. I next rolled into position. Once in position I was able to determine where the cut-out for the motor needed to be and I could finish up the ceiling with the unit rolled out of the way. Once that was done, I rolled back the unit and slowly added blocking to front and back, raising up the whole unit the thickness of a 2x4 at a time. This took some time and I did have one accident where most of the blocking fell and the unit crashed into me - luckily the back edge was still supported and I was able to hold the unit up until I could get blocking back under it (I do have a nice large bruise on my left arm as a temporary record of the event).

Once the unit was up about an inch higher than the bottom stand legs, I nudged the wood support until I could get the right back leg attached, the nudged and rotated the stand until I could get the opposite leg attached, rolling the stand towards me so the back corner leg was exposed. I put a 4x4 block "leg" under the front corner for some extra support and attached the leg in the back corner. Using this same support I rolled out the stand, holding the unit upright to pass the temporary leg. I finally attached the front leg and was able to tighten everything up - I ended up needing to shim the front leg to accomidate differences in floor height to level. There were a few moments in there that caused the ole sphincter to tighten, but it wasn't too bad. I did feel like I had been in a fight the next morning with soreness all over. Nothing like holding up 300 or so pounds of top-heavy metal by yourself while maneuvering around, with a possibility of the whole thing falling on you at any minute to get the stress up.

Finally I attached the filter and placed the dust canister underneath. One thing I didn't think about was the need to remove the cannister - I'm going to have to keep space open next to the unit so it'll roll out. I'm thinking right now of placing a piece of wheeled equipment there so it can easily be moved for dust canister removal.

Here's a close-up of the motor cut-out. Everything is well wrapped in HVAC metallic tape, as are all seams throughout the ceiling - this is to isolate as much dust as possible from the rest of the house.

I also started working on one of the metal/wood workbenches I picked up in that haul that included the Walker Turner sander. This bench was pretty rough - paint flaking off everywhere on the metal stand as it had been painted an institutional green. As the underside showed a gray I decided to go with Rustoleum Dark Machinery Gray, over brown primer. The entire stand was first sandblasted to removed as much of the old paint as possible - it's not perfectly smooth but it'll do as a working table.

The idea was not to get this to furniture quality, but rather to create a reliable work surface without paint flaking off everywhere. To that end I also sanded and filled the maple butcher block top - it had actually been flipped at some point so the worse surface is face-down - it's filled with hundreds of drill holes, cuts and scrapes. It must have been used in a metal shop where people liked to use it to support drilling - it also had numerous burns and spills saturating into the wood. I got off most of the muck (oil and metal shavings) using 80 grit (both sides), filled the worst holes then re-glued/clamped some strands that had delaminated, before I surfaced again with 80, following up with 120 and 220 on the top and edges. I also replaced the missing threaded rods that hold the ends together (3/8" threaded rod donated by fellow GWA member, Tommy Roland - an artisan if there ever was one and nice enough to share his knowledge and experiences). Here's a side view after one coat of BLO.

I plan to put 2 or 3 more coats of BLO on the wood portions before waxing with paste wax. I prefer the natural oil finishes for something like this that will get banged on, rather than film finishes that would crack with constant pounding and use - after all, it's not fine furniture. I've also completed about 1/2 of the space as far as sealing with HVAC tape. Still to go is sealing the rest, re-hanging my lumber on the standards you see in the pics, hanging the ambient dust collector, the ducting and some task lighting. Oh and placing the equipment - there's still that.

Did you ever get that dust collector hooked up? How is it working out for you?

It's been hooked up for a while - I need to update the pics. It works fantastically - much better than my expectations.
