Not easy to use

This was the first time I had used a dovetail jig, which I bought to make a chest of drawers. I was attracted by Leigh’s reputation.

The experience was disappointing. The main problems I experienced with the jig were:

1. The piece of furniture has to be designed to fit the jig. The width of the boards are limited and there is a gap of 27mm between the board options. For example, one can have 156-169 mm and then it jumps to 196-208 mm, then 235-248 mm, etc.

2. The jig is guided by a bush, which is screwed into the router table insert plate. The problem is that the router bits only have 0.5 mm clearance on either side of this bush. So, if the router bit is not dead center of the insert plate there is a nasty problem. I sheared the top of two bushes before Jessums, whose lift I use on my table, kindly supplied me with an insert plate, which could be adjusted.

3. A minor problem is that when a board is clamped to the jig, the pressure of the clamps means the bottom of the board is pushed out of straight, so it requires a shim. A small point but one that one would have thought Leigh would have anticipated.

4. There are two small plastic pins, which guide the two jig frames together. These are easily broken which makes alignment difficult.

5. A great deal of care is required to get the boards the right way round. This is not the case making them by hand.

Apart from that, I eventually ended up with my drawers but it may have been quicker to cut them without a jig. There is always a learning curve with a new tool but this was the worst I have experienced. The through dovetails worked best because they are both cut at the same time.

1st Impressions

Having waited almost 2 months, the RTJ400 finally arrived and I did a couple of test runs.
Set up was straight forward, instruction booklet and DVD covers everything very clearly,
It soon became apparent that to realise the full potential of the jig, you need to invest in the extra cutters and guide bush (and 8mm collet bush if you haven't already got one) Without these you can't do half pitch dovetails and you also have no choice as to which bit diameter you want for through dovetails. For this reason I marked it down on features and value as this increases the overall cost significantly. You don't need to purchase all the bits in the accessory pack and you can get the individual bits (Leigh) cheaper in the UK from elsewhere if you look on the internet.

An IMPORTANT FACTOR to bear in mind is that this system relies upon the accuracy of your router table setup. I built my own router table and have a Trend router table insert plate. When fitting the router to the plate, I relied upon the concentric marks to align the router to the plate. Although this has always been accurate enough for normal routing purposes, once you fit the guide bush, the effective opening is only about 13.5mm and you have little room for error when using the 1/2" (12.7) straight bit. My cutter just grazed one side of the bush and removed a few thou. from the inside. I may decide to reposition the router if I can find a way to align it with greater precision.

Overall, I'm pleased with the performance of the jig - you don't get the infinite adjustment of pins and tail widths like you do on the D4RM but then that jig costs well over £700. It did produce accurate dovetails and the operating procedure was simple once you were familiar with it. Would recommend it if it suits your needs and there are loads of instructional videos on youtube if you want to see it in action before you make up your mind.
