Cyclone and shop vac upgrade #2

Adding a small bead of silicon, will seal the voids.

(Apply a small bead and wipe it smooth).

 

When I need to seal a joint of dissimilar materials,  I generally use silicon adhesive/sealant.

Hi Russ,

I keep tubes of "white" and "clear", at-the-ready, in my shop and tool box.

It comes in very handy for many tasks---just like duct tape.

 

Clean the surfaces with rubbing alcohol before applying the sealant.  Wipe it on---allow it to dry.

Cleaning the surfaces of any foreign materials, will improve adhesive bonding.

 

Silicon sealant can also be applied to machine screw threads, to resist loosening.

 

For a permanent bond, use Loctite (R) thread sealant.  Different formulas for different uses---

"RED" for permanent bond, and "BLUE" for threaded joints that are intended to be serviced.

 

Generally, I keep a "Want-List" on me, when I want/need something, I jot it down.

I can always pickup the needed items on my next shopping trip.

(Rainy days make for shopping days).

Me too -- I think it's one of those "I still have plenty of everything except what I need at this minute" sorts of things.  I rounded the bottom edge over with a rasp, but now that you mention it, maybe I should unbolt it and put a real chamfer on it with the router.  What do you think about a bead of silicone around the outside edge and in the center where the edges don't quite line up perfectly?

Russ, 

Sometimes I don't find all the screws, in my bins, that I need for a task.

Many times I've used a longer machine screw and just cut-it-down to fit.

I try to keep a good supply of #8, #10 and 1/4" machine screws on-hand.

Helps alot when having to repair things.

Add a radius or chamfer to the inside end of the thru hole in the wood panel---

it will reduce turbulance, and make for smoother flow.

I've found shellac is most effective for sealing MDF.

Wood particle contain moisture, which will contribute to dust particle build-up around the edges in the opening.

Thanks, Ken.  I'm sure more bolts would certainly make it stronger.  I used three because I could only find three 1/4" bolts the right length in my entire shop!  You know when you stand at the workbench riffling through your bin of miscellaneous bolts?  That was me, 11:30 last night.  And two of the bolts are actually screws but since the nuts covered up the points I figured, "eh, screw it."  (sorry for the horrible pun - I couldn't resist!)  As soon as I go on a bolt/screw restocking run I'm going to add a few more.

You're right, I was thinking of sealing the mdf too, especially since the center hole will have all the dust passing through it and the bottom of the mdf will be exposed to the dust in the bucket.  I thought sealing it might probably reduce the amount of particulate that sticks to the mdf and either impedes the flow of dust into the bucket or sticks to the lid making a bigger mess when I empty the bucket.  Shellac on mdf, huh?  I'll try anything twice...

Hi Russ, 

Nice job.

Thanks for posting your fix.

I've found that adding (6) evenly spaced fasteners, near the outside perimete, provided move evenly distributed clamping forces.

Sealing the MDF with 2-3 coats of shellac will prevent the MDF from falling apart.

Russ, Looks like you have a very good Dust Collector.  Thanks for sharing.  George
