I have had a Hitachi M12V for about 20 years, but with age it has developed a small amount of wear on the plunge such that when in the plunged position the bit is a "bee's dick" off center.
I thus looked to buy what I hoped to be a vast improvement over a router that was 20 years old, and opted for a Festool OF1400, specifically for use with a Leigh D4R Jig.
As I have discovered, all is not as it seems.
I have the adaptor plate (Festool 463566) to mount the Leigh 716TP bush.
Firstly, the cutter shaft on the Festool is not concentric to the base system. It is about 0.15mm (0.006in) off centre, ie the cutter is 0.3mm (0.012in) closer to one side than the other. It just misses the inside of the 5/8 guide bush. I reinserted the Festool adapter plate @ 180 degrees and no difference. I did the same for the centre screwed mounting plate (permanent part of the base plate) and no difference. It is not the guide bush as it can be rotated with out altering the ?lack of concentricity. Presumably it is the way it is. Given the price and glowing opinions expressed about the Festool stuff, I would have taken it as a given that it would be concentric. My Hitachi was when it was new. I wonder what other people have found?
The Hitachi after 20 years is about the same ?out of concentricity? when plunged because of wear on the plunge guides.
The Festool Base has two straight edges. One has to use the short one that faces the operator if one wants the trigger with the right hand and be able to see and get at the depth settings. This short one runs against the fence for mortises on the Leigh D4R jig. Because it is so short (55mm) it is difficult to keep the Router hard up and against the fence and from rotating off the fence as you slide the route along to do the mortises. Because the router has two straight edges, the longer one is on the opposite side to the fence. This produces a situation where there is more base off the fingers (towards the operator) than being supported (behind the bit). This does seem a bit Irish to me (no disrespect intended). This makes it less stable than if it had a full circle or was reversed. You can turn the router around with the long edge against the fence, but then you are operating wrong handed and with the depth setting away from you. Am I missing something here?
The base is of a lesser diam than the Hitachi and also has a larger cut out in the centre, thus a narrower annulus for support on the jig and thus less of the fingers to support it. Visibility to the jig through the base is better on the Hitachi. With the Festool I am inclined to peer down under the jig to check clearances and finger location.
Also with the Base, I had assumed that the Festool adaptor plate (463566), when inserted, would be at the same level as the base plate, to form a larger bearing surface. It isn?t. It was on my old M12V Hitachi, so that you have a bearing surface the full diam of the base and right across the centre.
There is in fact 0.4mm (0.016in) clearance between the plane of the base plate and the Festool adapter. When the Guide bush is inserted the clearance between the guide bush "base" and the base plate is 0.63mm (0.024in). So when you are doing the tenons and the tenon spacing is more than about 40mm (the width of the annulus formed by the base plate of the router is about 35mm), the router is inclined to drop (by about 0.6mm (0.024in)) until the guide bush "base" rests on the finger of the jig. It makes nice little dents on the edge of the tenons.
Am I missing something here?
To sort it I had to pack the guide bush up 0.6 mm (0.024in), (thickness of an ice cream container lid) so that is in the same plane as the base. I wonder if this has been done on the demonstration router used by Leigh in their promotions of the Leigh jigs.
The Festool has the LHS knob as a plunge lock also. It might seem like a good idea, but I think not. When using it on the Leigh jig doing the Tenons, because of the smaller size of the base, you need to slightly twist on the handle to keep a very slight (away from you) moment on the router. Trouble is, this is inclined to release the lock. Picking the router up with one hand is also likely to cause the same result.
The Hitachi has two solid handles with the plunge lock capable of being operated by your left hand pointer finger whilst still holding the router firmly. Hands don?t leave the machine and the knobs never undo, and I can pick it up with one hand with out fear of any thing undoing.
The "plunge feel" on both routers is on par, although a little less depth on the Hitachi
However, I do like the quick stop of the spinning shaft on the Festool though!
As you would imagine I am a little disappointed. For the money it should have been the ants pants. (Trouble is I don't like the new colours of the Hitachi!)
I have hunted through the old posts and have found a little about the lack of concentricity, which does surprise me. However nothing about the differing heights of the base components.
This is for a router, that here anyway, costs twice the cost of the current Hitachi M12V2
I am not trying to be smart, just can't figure out why it is only me that it annoys.
