had a thought about making a set of skis on the weekend and thought I'd make my rails slightly differently.
Rather than have a thread on the outside of the rail, I've tapped a hole into the end of the rail.
I got some 12mm galvanised mild steel bar, grabbed it in my drill press using a 25mm block of mdf with a 12mm hole dilled through it and a compression slot cut through the hole in the MDF.
I then compressed the MDF around the 12mm bar with a vise clamp. This wasn't entirely successful and I then had to put a c clamp below to bolster the grip.
To get the rails long enough I had to turn the head on my drill press and pop a hole through the base.
I drilled a hole in the ends of the rails and then tapped them with a 6mm 1mm pitch tap. I found some stainless button headed cap screws to use and some fender washers to grab the ski.
The I was just about to make the ski's themselves and a transformer blew in our neighbourhood cutting power off!
Oh well now I have a job for next weekend
have attached some pics below
cheers - Simon
ps there are some pics of a quickie circle jig I made. After looking around here though, I think Im going to have to rebuild it with a bit more beauty attached, you guys do some nice stuff!
