P&P toys

[Paul Workman]

I've gone thru quite a bit of "ore" to find some gold. Thought I'd share a couple nuggets that I really like...



The Makita GD0800 7 to 28k rpm, constant speed, adjustable rpm 'lectric and the Snap-On PT200L pneumatic

Quality burrs (and priced below several others - even below some lesser quality) I find Fleetwood in Addison, IL to be a great source.

Well...I've done a little strategic filling (on my heads) and am now doing a little last minute shaping. Gotta put them toys to work!

DAYAM!!! IS IT SPRING YET???

With a 3/4" carbide oval bur mounted up that big bruiser Makita should wade through cast aluminum like a snow blower.

I'll play

Die grinder with homemade silencer, extension mandrel and 1in ball


Compressor in homemade sound reduction cabinet - this and the above silencer makes for happy neighbors.

Bob you have a long shank!



Seriously, when I use more than 6" it starts to whip, using an electric with adj RPM.....but even the low setting its still whips......is it the speed or my grinder.

Bob..

Details on the cabinet for the compressor.. I would like to do that to mine

Real good idea on the cabinet for the compressor.

Lee, your grinder may have a bearing issue. My POS Craftsman did the same thing. This Makita, however, does not whip - at least at moderate rpm (say 15,000 ish), and neither does the Snap-On. (I should add too that I cut the shanks to 4-1/2" to assist in reducing the whipping ) NOT whipping and having that long shank to where you can work around the far end of the runner and see what you are doing...is more than just nice.

Gotta look into that 1" ball tho. THAT appears to be "thee" answer to blending a smooth transition to the depth of my reference groove. (After an "oh crap" or two, I evolved to the point where I start with a 3/8ths dia., 6" (cut to 4-1/2") long shank bur and cut a longitudinal groove in the runners. Using a snap gauge I cut that groove to various depths along the length and proceed to blend the runner to that reference groove. Bob's ball would be just the ticket, methinks. (Thanks Bob!) As methods and tooling evolves, I'm feel less like a "Carbide Cowboy" (as Ryan puts it)

And, I like Bob's muffler idea and the compressor cabinet. I usually put the noisy (portable compressor) bastard outside and run the hose into the shop. It helps, but forget about trying to hear the radio with that thing running - sitting outside or not!

I have seen the cabinet idea in a few books, just a basic cabinet lined with carpeting, cork board.....or I would think sounds deadening mat like that used in a car would work also.

I'm mighty proud of my shank

You'll never completely get away from whipping with longer bits but you can minimize it through lubrication and technique.

It's just something I threw together out of 2X4's, plywood and sound board. I got all the supplies from home depot and even had them cut the plywood for me since they have that big fancy saw. Mine is tucked under a stairwell but you could easily do something similar against a corner wall. It is not dead silent by any means but it knocks down the noise level considerably. You will get significant heat build up in the cabinet if it is not vented, I fixed this issue by using a bathroom ceiling fan.

Bathroom fan mounted inside cabinet


Outside of cabinet: PVC tube is the vent for the fan, switchbox used to turn on compressor and fan together, second water separator.
