My d24000 is about 15 years old now and currently waiting on parts. Have not done much tiling past few years. We went to pick out some tile and noticed most are rectangular and very very big. The only tile we really liked in the whole store was a 24x48 porcelain. I thought I could get by with the old 24000, but I noticed issues cutting perfect edges in some 24x24 porcelain. Most of the tile I used the d24000 was 12x12, 16x16, 18x18 and various mosaics and small format tiles. I used it for a lot natural stone, porcelain and occasional ceramic. Now, the 24x24 tiles were not cutting perfectly straight, so I closely inspected the saw after I had already ordered new rollers and a new rail and noticed that there is not actually anything wrong technically speaking. It is the saw design. The d24000 will not cut straight past 18 inches or something like that. Past 18 inches, the rollers are not fully supported by the rail and the cuts will wander every time. So I now find I need to use a rip fence and lock the table for those longer cuts that need to be totally straight.I went ahead an ordered the d36000 before I really figured out the real issues with my old d24000. I gave the new d36000 a very close inspection before deciding to keep it. I almost returned it and after dealing with the 24x48 porcelain sort of wish now that I had just taken it back.. The good thing with the d36000 is it will cut the 24x24s perfectly straight. Before I ruined some very expensive tiles, I made sure the new saw was set up absolutely perfect in every way possible. So there is basically the same issue on the d36000 as with the d24000. I never did much cutting of anything bigger than 18x18 in the past, so I never noticed the problem. Now I see the d36000 will wander past about 25 or 26 inches the same way the d24000 wanders past about 18 inches.I found that the saw will also need extra side support to cut the xl format tiles like the 24x48s. I looked online to see what might work and saw adjustable height conveyor tables with tray rollers on top, but they were not available right away and cost was very high. So I just modified one of my adjustable height outfeed support tables that I use with my table saws and miter saws. I bought 4 galvanized tray rollers and screwed them to the top of the outfeed support and voila no more trouble supporting those huge tiles (at least where they can actually be cut within the limitations of the saw).I'm a little disappointed, but my bad for not paying attention. I feel like the d24000 should really be marketed as the d18000 and the d36000 should be more like the d26000--then Dewalt should really make a saw that could actually be d36000 which could be less cumbersome with all the 24x48s and larger which are now a common size.Will it take 15 years to design yet another bigger capacity saw? I wish they would make one with closer to 24" to left of blade capacity and a longer support rail to acutally be able to cut straight beyond 26". Seems like they could definitely design something like that without being all that much heavier than the d36000.So far, I have used new D36000 for a powder room mosaic floor, some ledger stone panels, some 24x24, and struggling through the xl format 24x48 kitchen floor tiles. I really sort of regret my purchase because...the old d24000 would be fine for most of what I need to do since I still sort of need the handheld wetsaw or grinder anyway for those big awkward cuts. I think I could probably get by somehow with d24000 with 24x48s.--So we are now looking at 36x72 tiles for a bathroom and I am wondering if I should take Dewalt up on the 90 day money back guarantee. I have been frustrated with various aspects of the saw. I know it is only designed for up to 36" tile, but the most common size tiles are rectangular and after shopping some more at tile stores the 24x48 seems to be one of the most common sizes and 36x72 are not that uncommon anymore. I ordered a snap cutter that will handle the xl format tiles (including the 36x72 we are looking at). I also have the kobalt handheld wet saw and various grinders. I already sold the old d24000, so I am leaning towards keeping the d36000, but I have really done the research now and there are decent looking rail saws for a little bit more money that will cut the 24x48s, but one to cut the 36x72s is a lot more money.I was able to get most of the 24x48 cut with the d36000. I got 10" wide galvanized rollers with brackets and screwed them to an adjustable height outfeed support stand for side support for the really wide cuts. For long cuts, I went and bought a 24x48 sheet of 1/2" pvc, cut it to 24x36 and mounted it to the table with a quick release system using thumb screws strategically placed in a few spots. I got 2 different sized clamping cutting guides from HF tools and I got also got a 50" bora clamping guide. I can now process 24x48 porcelain on the d36000 and seems like it might handle the 36x72s if we get them though I am waiti...
