What’s in Your Bead Blast Cabinet?

 

It’s been a long time (too long) without a tech tip, so here is a good one. 

My first introduction to “bead blasting” as it’s most commonly called, was during the fall of 1979 in the Motorcycle Mechanics class at Hutchison Vo-Tech.  And what a wonder it was to everyone in the class.  Parts that were dirty, carbon encrusted and with burnt-on oil deposits suddenly looked like brand new parts!  Of course, every motorcycle shop I worked in from there on out had a bead blast cabinet.  A great tool, and an even better one when used properly.  Can you believe it took nearly 40 years for me to discover the proper use of that tool? 

One of what I considered to be an idiosyncrasy of the bead blaster, turns out to be just a symptom of that misuse, or should I call it misguided use.  But recently, I found the answer to the question that I had failed to ask, or rather the observation that I should have put in the form of a question. That observation goes something like this: when you put fresh clean glass beads in the cabinet, you get a bright clean finished product, especially when the part you are working with is aluminum.  But when you load those nice clean beads, it always seemed that they just didn’t want to clean all that carbon and baked on grease off of the part as well.  Then after running a goodly number of parts through the cabinet, it would seem to remove the deposits more quickly, but as the cleaning improved, the finish went from bright to a dull color that seemed to also pick up any greasy fingerprint that came within spitting distance of the part.  I, and I am sure many others, got in the habit of trying to make sure relatively clean beads were in the cabinet whenever a nice final finish on the part was important.  I had often considered purchasing a second blast cabinet so that one would always have fresh clean beads for that purpose, but suffered along with changing the beads as needed instead.

So, where did I finally learn the proper use of a blast cabinet, you ask?  Probably the last place in the world one would think you would find technical information.  Ebay. Yes, … Ebay.  It probably began with a general internet search for glass beads because the source I had been using suddenly and without warning tripled its shipping charge to get a 50 pound bag  to me from the other side of the city. As is so often the case, a search for nearly anything will come up with a result from Ebay stating “buy fill in the blank on Ebay". But this time it was a winner. 

It turns out that Tacoma Company not only sells their abrasives on Ebay, unlike other suppliers I have dealt with, they provide information on the proper application of their wares. Not saying other suppliers don’t have that information, but sometimes you don’t even know that you should be asking a question, let alone what that question might be. 

So the answers to some of the questions I had not known to ask are as follows:

1. Glass Beads are round and are meant to “peen” the surface, not to clean it. 

2. Glass Abrasives are sharp and do a great job of cleaning but leave a dull finish that dirt will impregnate easily.

3. Glass beads can and should be used at a much lower air pressure which keeps them from shattering and turning into abrasives.

Armed with this information, a couple years ago I added a second blasting cabinet to my shop.  Now the first stop for heads and other parts needing the carbon, baked on grease and grim or paint removed is into my old industrial quality blasting cabinet containing glass abrasives to clean then quickly and easily. Then the clean part goes into an economy blasting cabinet at a lower air pressure for a bright finish that does not pick up dirt easily.  An added bonus is that the glass beads now last many, many times longer since they are not being broken up by the high air pressure.  Who knew?

Now, if you have a supplier of the proper abrasives down the street from you, obviously you can purchase the correct product for your application cheaper if you don’t have to deal with shipping costs.  As for me though, I will continue to purchase mine from Tacoma Company since the information they provided has not only saved me gobs of time, it has helped me to present a better looking final product.

No More Anonymous

 The spam in the comments section for several of my posts has become unbearable.  Well over 300 spam comments on a post from 2007, divided between about a hundred for online casinos and the rest for online credit reports.  I trust anyone who came here to read what I write is intelligent enough to know those are VERY likely fraudulent attempts to steal your identity. However, since I get an email notification every time a comment is posted, I've finally had to make a change. In the past a lot of the spam was for online porn, which I always took the time to delete. In order to limit this time consuming stupidity, I have adjusted settings so that in order to post a comment you will either need to have an account or subscribe to this blog.  In other words, no more anonymous comments. I know some won't want to take the time to do so, thus comments will be somewhat limited, but it should filter out the fraud robots. Thanks for your understanding.

Grace Abounding

 This is the message that I preached on November 1st, 2020.  Perhaps some of you reading this, who like myself spent much of their lives as bikers, can relate to Manasseh, king of Judah.

The Emperor Has No Clothes

 

The Emperor Has No Clothes

 

The wife and I went in early this morning to exercise our right to vote in the Minnesota Primary Election.  As expected, it was an interesting experience, given our Emperor’s …oh wait, I mean Governor’s executive order that all subjects (whoops, there I go again – I mean citizens) wear masks in public.  Neither I nor my better half choose to participate in what I have branded “COVID-19 Theater.”  Since at this point in time it has become self evident that, like the recovery rate, the virus is well over 99% political with the health concern coming in at a fraction of a percent. Jane considers wearing a mask to be participating in a deception – in other words, immoral.  For me, it is simple: when a Governor violates the Constitution, it is he who is the lawbreaker and not the one who disobeys the unlawful order.

The former one room schoolhouse that now serves as the Township Hall (as is common here in rural America) was the busiest that I recall in the seven years that God has greatly blessed us in allowing us to live “out in the country.”  We were the only people there not wearing masks. As expected, we were met at the door with an offer of a mask, which we politely declined.  Upon reaching the first Election officials, I was VERY STERNLY informed by one lady that, “YOU HAVE TO WEAR A MASK!”  … to which I replied, “I won’t.”  To be perfectly truthful (which I strive to be), I may have added “we are not communists”, but perhaps I did not express that thought aloud.  In any case, the other Election official at the table jumped in at that point, confirming my name and address so that they could issue a ballot, and she did it in a friendly, non-confrontational manner.

By this time Jane was ahead of me, given that it became a near farcical effort involved with me being able to understand the instructions that the lady was trying to communicate to me through her mask AND a 6 foot tall plexiglass shield (and yes, I was wearing my hearing aids, but to little avail).  As Jane approached a voting booth, another Election Official jumped in front of her to “sanitize” it, but she brushed it off, saying she was not afraid of a few germs.  Another example of pure COVID-19 Theater. Having spent a goodly amount of time researching disinfectants in order to help formulate a “reopening plan” for our Church earlier this year, I m perfectly aware that according to the CDC’s (Center for Disease Control) website all of the disinfectants available require keeping a surface wet with the disinfectant for a minimum of 5 minutes (and many 10) in order to be effective.  Similarly, masks are just another theatrical device, but at least mask and disinfectant manufacturers are making profits, unlike the countless small businesses that are now bankrupt.

So, is anyone else out there willing to go out in public without a mask and in effect proclaim “The Emperor has no clothes”?

A Few Thoughts I'd Like to Share


What this nation REALLY needs right now

… In fact, it may be even more to the point to phrase it this way: what the WORLD really needs right now.  But let’s just limit it to the USA for the moment. 
 
We, as a nation, seem to be between a rock and a hard place.  Make too little of COVID-19 and vulnerable people will die.  Make too much of it, and the national economy will die.  It’s almost as though the United States is under the judgement of God.  Scoffers will dismiss that idea as the superstition of backward mindless zealots. The Governor of New York said as much recently. Some others, who are willing to admit that there is a creator God, will be offended by the mere thought that such a supreme being might bring discomfort to those who he loves so much; you know, those for whom he has a wonderful plan for their life …

The Old Testament scriptures are filled with the record of God’s people falling away and undergoing his judgment to bring them to a place of repentance.  Though those judgements which were meted out by God upon heathens may come to mind first, they are relatively few in number compared to those his chosen people of Israel brought upon themselves.  The seven plagues that were unleashed upon Egypt in the days of Moses make the Corona virus look like a mild headache in comparison.  The destruction of Sodom and Gomorrah via fire and brimstone was decisive and fatal, and unlike what we see in our present situation, left no doubt that it was God’s judgement.  The worldwide flood that destroyed all of mankind except for one family will only be outdone by a fiery one that is yet to come. 
 
But the nature of God’s judgement is not always so dramatic.  When asked about a tower that had fallen on eighteen people, Jesus did not call it an unfortunate accident or even speak specifically to the sinfulness of those who perished.  Instead he said “think ye that they were sinners above all men that dwelt in Jerusalem?  I tell you, Nay: but, except ye repent, ye shall all likewise perish. (Luke 13:4-5)

Repentance!  That’s a word we don’t see much anymore other than the occasional cartoon figure of a robed, long bearded man holding a sign with the message, “Repent, the End is Near!” Now, whether the end be near is not within the scope of the message I have for you today. But repentance is.

That COVID-19 is a judgment from God upon our nation (or make that ‘upon the world” if you want to go with the big picture) is not my point.  My point is that COVID-19 AND the impending economic collapse together ARE a judgement of God, though at the point in time in which I write this, we might more accurately refer to it as “a call to repentance” rather than an actual judgement.  Yes, I do believe that our present crisis is far too mild, both in terms of deaths and the amount of economic hardship, to properly call it judgement.  When Almighty God does bring judgement upon a land, it is likely to be described with phrases such as “not one stone left standing upon another” when speaking of buildings and “in hunger, in thirst, in nakedness and in want of all things” to describe the inhabitants.

No, we are not to the point of God’s full wrath yet.  But we should ask ourselves, why not?  We allow the murder of babies while still in the womb, recently going the extreme of sanctioning that murder on the day of their birth.  It has become fashionable to celebrate every vile thing that God calls an abomination. Sex outside of marriage, and marriage outside of nature. Men burning in their lust toward men and women doing likewise.  They might say that “love is love” and “abortion is healthcare”, but the word of God which does not pass away still warns, “woe unto them that call evil good, and good evil”. (Isaiah 5:20)

How long will our nation continue to laugh at the idea that there is a God while secretly (and sometimes not so secretly) cursing him under our breath?  How long will the majestic, infinite, eternal, Holy Creator of all things allow us to continue in such vain rebellion?  I suspect it will be until repentance or destruction comes about.  He IS a patient and merciful God, but do not test his patience in order to satisfy the lusts of your flesh, forgetting that you are really only storing up for yourself more wrath for the day of wrath when God's righteous judgment will be revealed. (Romans 2:5)

Now, if Jesus Christ is your Lord and Savior and friend (for if you are not his servant, his disciple and his friend, he is not your Savior either), then neither plague or famine should terrify you. If King Jesus sits on the throne of your heart, don’t let COVID-19 make you anxious. Say along with the apostle Paul: “to live is Christ and to die is gain!” (Philippians 1:21)

Christian friend, do not hold on to earthly possessions so tightly that you are driven to despair at the thought of losing them. Rather, again with the apostle respond: “In any and every circumstance, I have learned the secret of facing plenty and hunger, abundance and need. I can do all things through him who strengthens me. (Philippians 4:12-13)

But, on the other hand, if you cannot honestly claim the name of Christian (and may God grant that you be not deceived in that matter) then those words of comfort are not for you.  Whether you reject this present “shamdemic”, because you are young and healthy or because you believe the “cure” to be worse than the disease, then I urge you to shelter in place.  Don’t take any risk of contracting what may be a deadly disease! And that goes for not only COVID-19, but every other kind of flu, infection, or accident. Without Jesus, the lake of fire is waiting for you! Stay at home, hide under a table and seek the Lord, for without him you are facing an eternity where the fire is not quenched. (Mark 9:48)

If you are an atheist or agnostic, Jewish, Muslim, or Buddhist who is already staying at home as much as is humanly possible, in a state of mild panic that you may be stricken by this deadly disease, then stay there! Take cover (under a table in an inner room might be best since its almost tornado season) and remain there cowering from a very dangerous world that can kill you in uncounted ways.  Stay there until you have repented of your sins and finally have peace with God.

What does this nation really need right now?  The same thing the whole world needs right now: to come to the place of repentance toward God and faith in the Lord Jesus Christ!
