cutting 1/4" lexan?

[slowngreen]

What would be the best way to cut a peice of 1/4" lexan without making it chip or crack? Table saw? Scroll saw? What blade would be best?

i use chop saws / table saws to cut almost every thing (just what i have) and iv found a high tooth count and a slow feed speed works well on most things

can be careful with a dremel. If it starts to melt a little its no big deal normally the "hangers" will snap right off once they cool. I dont recommend if you are cutting big pieces though. It works good for small little things.

This is how I cut it as well. Feed slow.

Ok thanks guys. I have access to a table saw so I'll prolly go that route. The cut will be about 48" long, will I have to worry about going to slow and having it burn/melt?

They sell triple negative rake blades specific for plexiglass work, you can feed it pretty damn fast on the tablesaw with the correct blade, I bought one years ago when I was doing custom nano fish tanks,

i use my dewalt 12" miter saw with high tooth count saw blade to cut delrin and 1/8" plate along with 1/4" x 1" alum bar stock....i just hit it with bout 1/6" or so deep cut at a time....i made a jig with a block of 2 x 8 to hold down flat stock from the blade ripping it upwards ...........bob

When I cut it at work for machine guards I usually just use a jigsaw. Only problem is getting a nice straight cut!

[romulus22]

thickest i usually work with is 3/16. and when cutting lexan we just use wood blades on the jigsaw or on the circular saw for long cuts like what you are doing.

i use my bandsaw and it work awesome

[slowngreen]

I was thinking about just using a jigsaw but I really want it to be straight. Its a windshield on my Teryx and I want to beable to put it back together when winter is here again without any gaps lol.

I used to cut 1/2 inch lexan with a jig saw,,,16tpi blade I believe,,,masking tape on the saw plate and on the piece getting cut,,straight edge clamped down to make error free straight line cuts

Rotozips work wonderfully too. All the pieces are thrown out the bottom

Circular saw with a new carbide tipped blade works wonderfully. When making long cuts like what you want, I clamp a 2x4 or similiar to the lexan and use that as a guide.
