Actually you don't know what you are talking about. On this and many other subjects. Like bugs in the corn! Give me one good reason why you can't spray a lag with either WD40 or Pam before driving it. Just one. You can't. You really are something wigwam.
Michael, I regret to inform you that I have been doing this for 32 years and have used every kind of fastener known to man........there is nothing better than the P-Chink one.....aaaaaaaaaand you don't have to spray the d)*)m thing......If you spray with an oil....and overspray and then apply a water based finish....you got problems......Back to the corn on the cob argument.....there are inert products used for blasting all sorts of items.......blast some corn and you have a medium for growth.......try and get recycled glass to grow mould......try some corn cobs and see what happens......corn cob blasting is a scam......it is too coarse and leaves a pitted log.....
How long have you been doing this???
1. Are Alan and Tim the same person? It is impossible to know, but your tone and answers mirror each other too closely.
2. The video is great and I could show the same thing using corn media and get the same results.
3. Tim - sorry about your regrets in being in the business. I have none. I have been building and restoring log homes since 1982 - not quite as long as you have - and I am always doing my best to stay abreast of new technologies and products, and, on occasion, coming up with them. For instance, the P-Chink fastener was originally the Log Hog by OMG. I worked with Bill Moffet (RIP, Bill) on the development of the Log Hog. You are welcome!
4. I build for many different manufactures and always build to their specifications. If they send us lags, that is what I use. Both WD40 and Pam evaporate long before they can affect the application of the stain - there is no mixing of oil and water, as you are implying. This is a time-tested method - try it before you judge it.
5. As for blasting, I have tried glass media and personally I don't recommend it. The 20/40 corn media works better at removing the finish. Corn is 100-percent biodegradable; glass is not and it is recommend by the manufactures that it be cleaned up and not left to sit or blow around. Additionally, corn does not etch aluminum or glass and it can be sifted and reused, making it more economical. Corn DOES NOT attract bugs or produce mold.
By the time a house requires blasting and refinishing there usually is a breach in the seals around the windows, chinking, rafter joints, etc., allowing the corn to sometimes get into the house. (I do have a way around this, but no use giving away all my secrets.) Because of the silica in the glass, it is not recommend for use in houses or near or around pets and people. Corn is much safer. Check the EPA regulations on using glass and sand on residential and commercial buildings.
As I have already explained, you simply blow off the log walls with the compressor that is used to run the hopper to remove any corn residue. If a proper job is done when staining and sealing, it is impossible for mold or mildew to grow. Like fire, mold requires three ingredients - remove anyone of the three and you don't get a fire (basic physics).
As far as the final product, there are many people who like the finish left by corn blasting. I do doors, beams, rafters, outside logs and even interior walls for people because they like the way it looks. For those who want a very smooth finish, we simply buff it out with an Osborn buffing brush (but usually only on the touchable surfaces like the walls, not the facia, soffets, etc).
6. I read Alan's comments about me not being a craftsman and there are hundreds of people who would say otherwise - I craft and build log homes, offices, barns, church camps, lodges, additions and furniture. I have even built in Japan.
7. I have noticed this site is a venue for hand crafters to slam those of us who build pre-cut homes. Both are an art and both have their place. Putting down another person is only done when one is not confident in themselves or their craft. Alan's house on his web site is gorgeous and it displays his craftmanship. Because many of the readers on this site are novices, posting on this site should be geared toward them and a level of professionalism and true advice should be maintained.
I'm curious where you heard that crushed glass media contains silica? Or perhaps we're talking about different media.
The glass media that is sold by Sashco & is used most widely in the log home industry is made from recycled glass bottles. It is chemically inert and non-toxic, and contains no silica. It is listed on the EPA’s Comprehensive Procurement Guidelines for blasting grit, and is approved by the California Air Resources Board (and you know if CA approves it, it must be very safe & environmentally friendly because CA doesn't approve anything!). Depending on the grit used, it can be recycled through the machine again, saving money. It can't be recycled as much as corn cob, but the cost of a bag of media is a bit less, which makes it a wash, overall. We've been told by several contractors that it saves them money not only due to the cheaper price of the media, but also because of the cleaner surface it leaves, little or no secondary prep is required.
That said - I know many contractors have their preference for one or the other, others for walnut shells (which is much cheaper in CA where walnut shells are available in abundance). I also know some who like to mix the glass & cob. To each their own. I just was curious where you heard about the silica in the glass.
I have to get to Prescott today but I will respond tonight. This was never about what is better. It was originally about someone saying corn cob attracted bugs and mould. By the way all I use is Shasco. I buy everything from Mike Cary at Mountain Home Building Products.
I agree - I don't think there needs to be debate about what is better. People have their preferences and, as long as they're doing things right with either one, either will work quite well. (Sashco obviously prefers glass, but we won't ever tell anyone that cob media is bad or wrong.) I was only concerned about where you heard about the silica in crushed glass media, only because I don't want other people thinking it's unsafe, but if you've heard of some crushed glass media that DOES have silica, that is important to know which product it is.
And I thought I recognized your name! We're glad to have you as a customer. :-)
