I own a 'rat, and am happy, but was at the Homewood workshops the other day, when they were reviewing jigs, and sharpeners, and they had the Leigh chap from Brimarc demonstrating.
Boy, I thought perhaps everyone who kept saying how hard the woodrat is to understand and learn might be correct, until I saw the Leigh in action. OK, there is a one off time to learn the woodrat but after that, it's plain sailing. I can finish a batch of drawers in the time it takes to setup a Leigh. He only had an hour to demonstrate the Leigh dovetails, finger joints, the "fancy joints" the M&T, sliding deovetails, so he was motoring through the demo, but even so, "slide this bit in", check, "draw a pencil line here", take the wood out, "put the other piece in", flip this the other way up, "take a cut", careful yiou dont' dip in between the pins, watch out for tear out here, "flip this back, loosen here, align here........ it went on a bit I have to say! Also, quite a few time when demonstrating he seemed to set things up on the Leigh "by eye". He kept saying align this to the 20mm graduation etc. I guess I'd presumed that there wasn't any "set-up" on the Leigh which was "user" adjustable.
Now it did produce some lovely dovetails (the Leigh), and I'm impressed with the quality of engineering, but, he did use pencil lines to assist him which I found interesting (depth setting I think), given the Leigh people who like to tease us 'ratters! The joints were spot on, but the tearout did concern me slighlty, he rather glossed over it and said he had a "blunt" cutter. :? Anyway, it answer to the original poster, it does take quite a long time to setup, and I have limited enough time as it is. One thing I particularly like about the 'rat is you can use it immediately.
I mean basic Leigh machine? £300? Finger Joint template = £235, Set of three "isoloc = £430, Leigh M&T jig £630.... You ain't gonna see any change out of £1600 for all the bits? (I know it's a bit cheeky to include the M&T, but it comes "for free" in the 'rat!!! :lol: So... instead of thinking the 'rat is expensive, you could, in a way, consider it just a third the price of a Leigh, with all that additional flexibility and functionality.
The woodrat always gets knocked for cost, but if you add up the price of all the individual bits of the Leigh - it's real expensive, and for every extra function you need, you have to buy a "new" bit, or template, or whatever. I like experimenting and trying new things and ideas out on the 'rat. I made some monster joints for the garden gate a while ago. The manual is much improved and has plenty of suggestions of other joints to make, if you are stuck for inspiration.
For a production environment, the Leigh looks superb, fast, accurate, reliable etc. But for a budding WW, who makes lots of different projects, unusual joints, experimenting etc. I'd recommend the 'rat. If I had a big enough project, with enough repetition, I'd really consider it (a leigh) , it would be a blessing. For the limited number of projects I have, I don't think it has enough flexibility to do other things.
I thnk the main thing to remember, is people have been cutting dovetails "by eye" for hundreds of years, with unbelieveable levels of accuracy, dare I say, better than machines? :shock: Let's be honest, we are only using machines (either 'rat or Leigh) to make joints we have neither the time to learn nor skill to do by hand.
Occurs to me I haven't actually answered the original question...
"I would like to know why woodrat users think they are so great? "
I like mine 'cos it's
fun to use. The machine is limited by my imagination, not by my ability to purchase a new template, which had been designed by someone else. I also find it intuative, I can try something new. In the same way people build hundreds of jigs and bits and bobs to extend the abilities of thier tale saws and router tables, it also, should you be willing to invest the time to make a jig or two, have it's capabilities extended even further.
I think the picture (below) demonstrates most of what I've been trying to say. I built this almost entirely on my woodrat, and there's no dovetail in sight. I had this before a table saw, so it was used to square off all the ends, produce the M&T in the doors, the M&T for the shelves, including the extended pins for the walnut wedges you can see. It angled the top and bottom surfaces (not sure if they are shown in this picture)..... I produced mortices the full width of the sides, and also set it up (a bit like a router table) to produce the mouldings on the tongue and groove planks that make up the back. (in fact they aren't quite T&G as I wanted a more decorative, and complex profile).
