Forum home made wall saw

[pj]

You could think of using Bosch/Item rails as being extrusions are extremely rigid for their size as well as having slots into which you can fit plastic runners. It's very versatile stuff.

have you got any further with this project yet jason?

Im still looking at the clamp and guide rail but right now i'm so busy theres not time to play !

Spurred on by someone who posted saying they did not have a spare wall to mount such a thing on, I've had an idea.

Imagine a grid frame of say 2 x 2 and each cross joint with a bolt through and supported from the ceiling and just resting on the floor possible a few degrees off vertical. One of the horizontals could be a ledge to support the long edge of and 8 x 4 and some sort of guide rail scheme to guide the saw.

When not needed the whole thing could be pushed up and secured in the roof space using each bolt as a pivots above head height

Don't think I've described it too well - so if you can't follow what I'm on about post back here and I'll draw something in the next day or so.

Bob, I've seen various versions of the ceiling stored wall saws in US sites and all seem to work well. Of course I canny find a link or a picture.

You should get the article cut list etc etc

Alas Jim, need a S/N recognised email address. Would have been interesting to see it.

For Noel and anyone else here is my Workshop UK folder with some of the above files and other stuff related to this thread. I plan to drop W-UK related files into it now and then. It won't be meant to be an orderly info source just odds & ends. It have been checked for virusses when uploaded (and there were none ;D)
Hope it is useful.

Bugger! Another idea that someone else has beaten me to! There was me thinking it was original. Wouldnot mind seeing a picture if anyone finds one.

Thanks Bob for the files.
Sorry about the ceiling stored wall saw...I'll try and find some more info.

In another forum, a guy made a cutting table for use with his circular saw and rail. He stores it in the roofspace of his garage using one of these. He uses his cordless drill to 'wind' it up and down.

Don't know if anything like that is available over here. I guess if the wall saw was pivoted at the top of the wall, then you could use something like this to swing it down into place.

For anyone who hasn't seen it the Woodsmith plans build this:



and the hardware kit is a very reasonable $170 + shipping, however I doubt that something like this can be swung up and down without suffering from racking and therefore inaccuracies. I also feel that limiting the working method to just crosscutting is potentially too limiting. In the USA Rockler do a similar plan as well as offering the hardware kit. Either way many of the components are sourceable here in the UK

I find it interesting that there are already other, simpler, designs for use with the portable power saw, like the one on PlansNow:



which seems quite close to JFCs' concept (?), but more to the poinyt it can accommodate long rips.

Thats what i'm thinking I also think you can lose the vertical cut as you can just flip the board round and cut it on the horizontal .

[Dave S]

Ian Dalziel made one in Good Woodworking a few years back. He supported the sheet on rollers. To rip, he turned the saw 90^o, locked it in place and then pushed the sheet through. Of course, that requires a much longer length of wall.

Scrit, your second pic bares more than a passing resemblance to some of the cutting tables that users of the rail systems are constructing, although all the ones I've seen are used horizontally.

I used to to have ideas about building a wallsaw, but I veered away from the idea when I discovered the rail systems, largely because they seek to address quality of cut issues. (I never managed to get an acceptable cut in MFC using a homemade sawboard, so always had to trim with a router which was a real pain). A wallsaw needed to do more than just break down large sheets to be dimensioned on the tablesaw, because I don't have a proper tablesaw.

Of course, I'm doing this as a hobby, so my needs and priorities are just that - my own.
