Levelling slabs
Hi, I've built a jig for levelling slabs 1500 wide by 3800 long using a bearing rail system like the wood wizz and the slab master. I've been using a router with the 50mm bit for levelling, but now getting sick of pulling router on and off so now going to a dedicated system. I've got a 3hp electric motor I'm going to use, wondering if anybody has seen any good blades out there I can adapt to use wanting something 100mm or bigger. Cheers

There is something called a "Safe-T-Planer" that cuts a 2.75" wide cut.
Dewalt used to make a 106 mm diameter one and I see there are a few on ebay

I recommend making some sort of guard for it.

Carbitool makes some planer heads. I use one of the 55mm heads in my router, but they also make a 80mm model which might be worth a look.
The replaceable inserts are great.

Yeah just done some reading on speed control for motors looks like I've got the wrong one (single phase). Might look around for a 3 phase one now, cheers for the replys.

Bob and Neil have already expressed the concern I immediately had. You need to calculate the peripheral speed as there are huge forces involved as the diameter of you bit increases. What speed is your motor? Probably a four pole (1500 rpm) would be better but everything depends on the size cutter.
Have a look at fly cutters too. I was talking to a friend who has an engineering works about preparing slabs and he immediately said "We'll just make up a fly cutter." This may give you some ideas just from Google Images.

I cheated, I got sick of trying to come up with ways of doing things that required this and that, We bought a Slabmaster problem solved, don't think we will ever be looking back, this machine can do so many things, much more than just levelling Slabs

We'll I made a bit of a prototype out of 50 shs but wasn't a heavy enough wall thickness so had a little twist in top rail. So built another out of 5mm wall 50mm shs. Very strong now also added some threaded rod to each corner to get everything spot on. Just using my router with 55mm planner bit for now but might have to fab up a motor with similar cutter disc as the slab master soon. But it does the job for now. Added a few pics as we'll, the frame is just sitting on a bench for now but I'll add adjustable legs shortly.
