Hi,

Beams are 45 * 70 * 2500 mm, angle is on the short side.

Any ideas how to cut this safely? Getting a strong feeling the best way is a table saw (which I don't have) and so I will not.

Unless there is a safe way of doing this? Maybe with the CARVEX (was looking for a parallel guide, but no dice)?

Thanks!

Place two or more beams of the same thickness side-by-side to form a wider, more stable base for the track to rest on. If necessary join them together on the ends to remove the chance they may separate or move during the cut.

Thats a good plan! Thanks.

Use a ripping (panther) blade or the motor will keep shutting off to cool down.

Will the TS55 even cut deep enough on the rail with a 15 degree angle?

Cutting thru in one go is going to be hard and prob. painful. Do shallow cut first (just short of halfway thru) and finish with cutting all the way. That way you will be able to see where you need to wedge etc.

Yes, it will. With TS55 you can cut up to 48 mm thick at 15 degree.

If they are smooth and straight you can use double sided tape to join them to each other or to the cutting table/surface.

And use the Panther blade which is for ripping.

If you don't like Signatures, just go to Look and Layout and tick No Signatures.

Not on the rail I think. But I suppose this is better done with a parallel guide anyway.

On the rail. Off the rail it'll cut 53 mm at 15 degree.
Good point about parallel guide if you wand a consistent width. A narrow 2.5 m long beam is unlikely to be as straight as the rail.

Is there a table of some sort of these values? My math may be completely wrong but I figure if it cuts 55mm at 90 degrees and 43mm at 45 degrees (12mm diff over 45 degrees) that's 4mm per 15 degrees so 51mm at 15 degrees off the rail. I always forget how much the rail is - 5mm?

15cos x 55 = 53.12

.9659 x 55 = 53.1259

Are you sure?

I think (been a while  [tongue] ) its: 55 / cos(15) = ~ 56.95

It would be cool if it could cut deeper at 15 degrees than straight.
