I'm partially with Jacques on this, brush, brush then brush some more. I tend to scrape less and brush more. You almost can't brush to much but you certainly can over scrape and be especially careful when "Hot Scraping" as you can do damage to the structure/base quickly when you're hot scraping. When you hot scrape the base is obviously much warmer and when the base is warm and you have a sharp scraper you can do a fair amount of damage in a hurry if you press to hard. I'm personally not a big fan of hot scraping. I prefer to use Swix glide wax cleaner every so often, depending on snow conditions. You can also use a piece of fiberlene in between your iron and base when you're hot waxing. Using fiberlene between your iron and base when you're hot waxing will help pick up any dirt or impurities from the base because they float to the surface when you hot wax and the fiberlene will collect the gunk. Because it floats to the surface you scrape it off anyway, wether you use the fiberlene or not, but if you do use the fiberlene it will give you a good idea of just how dirty your bases are/were.
To start out, if you can buy a oval brass or bronze, oval horse hair and maybe a softish oval nylon, that would be a good starting point and you can always add new/different brushes down the road. I'd recommend trying to keep your brushes as clean as possible. Vacuum them out as often as you can and be mindful of brushing out skis when the wax is still warm or when using really soft wax, like base prep, as it will collect on the tips of the bristles and when that happens your brushes will become much less affective. Always start with your stiffest brush and progress to the softest. I personally like Holmenkol and Swix oval brushes the best but you can buy Artech and Race Place brand brushes a fair bit cheaper. I like roto brushes for polishing and overlays but I think oval brushes work best for wax removal. With roto brushes, except for the metal ones, you can apply a certain amount of pressure but if you see the wax starting to smear on the base instead of coming off like dust, you are pressing down to hard.
Sorry to say this Jacques, but I think Scott's Beast vice is the worst POS I've ever used. I hated mine so much I gave it away and the person I gave it to no longer uses it either. IMO, there are many other vises on the market better then the Beast Vise. I feel really bad saying that, too, because I really like Scott he's a really cool ole dude. I've met him and been to their business a few times when in town for a race. Never been able to figure out how an outdoor patio furniture business ties into a ski race equipement business though. :) Not sure if you knew Brian when he was at Race Place but I miss him not being there anymore. The new guy is ok too, just liked dealing with Brian.
Very good info Mojo. I'm with you. POS on the BEAST vice!? Really, I like mine just fine. I've learned to use it in many ways. Yes, Brian left the shop. I have not seen him in some time now. Last time was last season at the inception of Crows Feet Commons.
In my brushing video I did go to town because of all the summer hot boxing and hard wax finish. For most "standard" wax jobs I do a soft stainless just a bit, then a bit of brass, then scrub it good with horse hair. Main thing I try to impress on folks is that it is hard to over brush.
BTW, I did a BEAST vice video. You probably saw it already. As all my videos, it's very......well, lets say "in-depth" Here she is again, Be good!
And this is how I use it for snowboards!
