Biagio - thank you. 11mm seems to be the critical dimension ok. I picked up most of the other stuff on various sites, including the 15mm for the cutter depth and the little tool to achieve it - wouldn't be hard to fabricate but a 15mm trench in a piece of hardwood ought to work equally well. etc. I can't afford a Festool now, so things don't change! I get by ok with a Bosch. I think I put up a thread about the Elu MOF 96 rebuild a while back - it was seized solid when I got it, the previous owner said a shot of WD40 would sort it out ;-)

I'm still fighting with this jig. Ive tried all possible guide and cutter combinations with my Bosch router, and none are even close to working. I have a few guides for my Elu MOF router, but none are anything like 11.1mm. It looks like the Trend one available on Ebay.co.uk is what I need - can anyone confirm if it fits the Elu? I've tried asking the seller on Ebay and the seller doesn't know.
If you run a trend router, could you please measure the distance between the centres of the two attaching holes?

There's also a four-hole one sold by Axminster.

John, just found an old photocopy of the original manual for the jig (English and German). I can scan and post, if you need it. Not great quality unfortunately.

Hey Biagio - thank you so much for your very kind offer. I think I actually have it - is it a booklet entitled:
Betriebanleitung und Ersatzteilliste 096 20 21 00

With an exploded diagram of the jig on page 2, referencing the part numbers?

That's the one. Glad you have it.
Had a look at my guide bushing after your posts - it was obviously not a Hitachi original. I must have bought an Elu one to use in my friend's jig, and drilled new holes to fit the Hitachi base. Funny how one forgets these details, 40 years on. Worked well at the time.

I subsequently bought a no-name-brand of the cam-clamping jig sold by Rockler and others, but have had the most use out of a template-making jig designed by an American called Richard Stottman (now sold by Milescraft). Allows you to make an unlimited number of templates in various sizes, for through dovetails and box joints. Works like the Elu jig, or with a router table (slightly different builds).

Only tool I have ever bought that came with a licence (to protect the intellectual property). Just ordered a centre-finder ruler from Lee Valley, to use with it (came with a paper ruler that worked surprisingly well).

Default waiting for the postman...

I'm waiting for my 11.1mm bushing to arrive from the UK. As soon as it does, I'll test it with the dovetail cutter I got with the jig, I might be lucky. If not, I'll buy one on ebay again.
Your Milescraft template sounds very interesting. I actually prefer box joints, I just like the look of them more than machined dovetails.
I have the Milescraft inlay kit, I really like it but it can be fiddly to set it up, and it's easy to nick the plastic templates with the router cutter.
I also have a friend and neighbour who has a CNC plasma cutter that can do amazing work on steel, I'm already wondering if I can figure out how to design alternative templates for this jig, that I could ask him to make. His plasma cutter leaves a clean square edge on 1" steel plate, it's an amazing machine to see in action.

Best regards

JC

Hi John, At my impecunious worst, I used my friend's aluminium template to make a copy in acrylate (Perspex). Kind of worked, but too finicky to set up. The thing about templates is that it is surprisingly easy to ding them - just try lifting the router a smidgin before the bit is completely clear of the template (you cannot rely on sound to guide you, as the bit will have completed the cut before it exits the template fingers). Steel fingers might be a bit rough on you dovetail bit under the circumstances- can your friend cut aluminium on his plasma cutter?
What the Milescraft thing does, is to give you a master template, from which one makes any number of working templates, from whatever is to hand - mdf being very suitable because of its dimensional stability.
Have a look at the manual on the Milescraft website - it shows how to make full, spaced and angled dovetails and box joints. You may get some ideas for the new templates you want to design.
Where the Elu jig outshines the Milescraft one, is in half-blind dovetails, where both front/back and side are machined in one pass. But remember which way each must face, and against which side of the jig, otherwise you land up with the equivalent of the apocryphal Aussie submarine, where instead of two matching halves, they built two identical halves - the world's first spoon-shaped submarine.
The Milescraft also cannot make rebated dovetails directly. The work-around is to glue on a false front, after completing the through-dovetails.

Nollaig shona dhuit, and all that sort of thing.

Default Setbacks...

Hi Biagio - many thanks again for all the info and the impressive greeting! I haven't had a chance to check out the Milescraft template yet. Well, on my first attempt with the new bushing, disaster immediately struck. In the second finger slot, the bushing seemed to jam, and of course I tried to wiggle it. The router kicked up, we had metal-to-metal, and the results were as you describe - a chunk eaten out of the template and a chunk flown off the cutter, so I'm chastened and back to the credit card. I've ordered a new cutter on Ebay, and I'll make spacer blocks so that routing will re-commence in slot No. 3. I wasn't planning on doing 12" box sides anyway ;-)

Best JC

JCJCJC: In your post, you said that the bushing became stuck in the template.

The picture posted shows a screw not flush with the bushing. If that is the case, that might be the cause of the bushing jamming as the router did not sit flat on the template.
