<div dir="ltr"><div>Like Eric, about 35 years ago I built one of the TP Tools blasting cabinet kits made from 3/4" plywood and it's been working great all these years. At the same time I also bought their vacuum kit and built a dedicated vacuum from two 30 gallon drums. The vacuum motor lasted all these years but finally gave up the ghost this summer so I bought their replacement motor and all is well again. I've probably replaced the window glass a dozen times over the years. </div><div><br></div><div> Mine is free standing and always ready to use. It is used frequently and every time I use it I'm reminded of the reason I originally built it, the restoration of a 63 spitfire :)</div><div><br></div><div>I don't know what I'd do without it.</div><div><br></div><div>Brad</div><div>Merry Christmas everyone :)</div><div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Dec 26, 2020 at 3:53 PM Eric Russell <<a href="mailto:ejrussell@mebtel.net">ejrussell@mebtel.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">I built my blasting cabinet based on plans from TP Tools. I later built <br>
a closed box that latches onto the side for larger/longer items.<br>
<br>
Being set up & ready to go at all times means I use it often. It's as <br>
simple as hooking up the air line and flipping a switch for the light. I <br>
also added a cyclone separator between the cabinet & my shop vac. This <br>
helps keep the view from being obscured by the dust cloud and helps the <br>
shop vac's filter last longer.<br>
<br>
Aluminum Oxide is available in various grits and seems to be fairly long <br>
lasting (but all media eventually breaks down and needs replacement). <br>
Recycled ground glass (available from TP Tools and likely others) works <br>
well and seems to have less dust. It might be a good 'all purpose' <br>
media. Walnut shells is great for fine cleaning - like carburetors. Be <br>
sure to clean out the cabinet before changing media - especially when <br>
going from coarse to fine. BTW, be careful using glass beads - when (not <br>
if) they are spilled it's like walking on icy grease!<br>
<br>
An assortment of rubber plugs/corks will protect threaded holes. A layer <br>
or two of duct tape will protect machined surfaces. Cleaning rusty <br>
threaded parts is fun - after blasting they'll often turn by hand.<br>

> 1. For those of you with blast cabinets, do you find yourself using it more than you expected? My first project would be cleaning up some suspension parts (mostly paint removal). I think enough projects come along that it would be worth having one, but I would love to be surprised to find additional uses.<br>

> 2. What is a good all purpose, reusable media to use? I would mostly be removing paint, and some surface rust.<br>

> 3. The first parts I would be cleaning have some machined surfaces (threaded holes, tapers, etc). How careful do you need to be to protect those areas? And what if the best way to do that? One of the parts will be a strut tube, which includes the stub axle. I’m thinking that wrapping that area in duct tape might be a good idea.<br>
