Jessem Stock guides

[siggy_7]

Peter, I think the problem with the build it track is it is substantially wider than the track itself due to the low profile sections each side for the fixing holes. I'd be interested in the dimensions though - Incra unhelpfully don't give this data on their website for some reason.

No nor do we, I will try and put that right. Sometimes it's only when you find another (possible) use for a product is it worth checking the dimensions.

The Woodpecker Dual Purpose Track is another possibility, from memory I think it's 32mm wide, but again would need to check.

Cheers Peter

I am trying my hardest to make these stock guides work on the 40mm wide fence to my table saw, the 1/4" tracks will work, hence the question, the problem I have created for myself is that I do want the 20mm distance from the face of the fence to allow the guides to be parked on top of the fence out of the way when not in use, this narrows the available space even more, also the fence has two annoyingly raised edges on the top of it which narrows it even more, however if you could confirm all the dims of the INCRA track I would then be able to work out if it will suffice to do what I want.

One of your guys has already given me the dims of the JessEm track and I have found this: http://www.jessem.com/assets/04301---cl ... guides.pdf , what I would really like to do is mount the guide to a track other than the wide one JessEm supply, that way I would not have some horrible cantilever off a T track when mounting the JessEm track.

Sorry not ignoring you, thanks for the information.

My other suggestion would be to route your own wooden t track in straight grained hardwood. One of the Wealden keyhole cutters should be able to do this in a couple of passes.

I would much rather have a nice anodised T track to play with, another but horrible solution, is to cut the wings off the JessEm track and mount that onto my fence.

We have measured and added the dimensions drawings to the website today, but the INCRA - Build-It - T-Slot Panel Connectors is 44.6mm wide and the Woodpeckers - Track - Dual Purpose Track is 44.8mm so both maybe to wide for you.

You may be better cutting down the JessEm to width if possible.

Cheers Peter

Yes both too wide, I have come to the conclusion that its either cutting down the JessEm track, which does not get over the parking issue of the guide, or increase the width of my fence by 30mm with a planted aluminium or plastic face on the right side and put two 1/4" T tracks in place one on top of the new face and one on the original fence, this will get over the parking issue and the cantilever, just a question of finding something suitable.

[MikeJhn]

Whilst looking for something suitable I found this: http://www.ebay.co.uk/itm/Aluminium-C-p ... 2556269452 Looks to be about the same dims as the JessEm T piece? think on.

Just had a brainwave - looking at the dimensions this may fit: http://www.aluminium-profile.co.uk/acat ... 92476.html alternatively I would fix some small metal angle to the right of your fence and fix the Jessem track onto that and your fence.

Thanks for the link Siggy, but that profile does not fit the JessEm guide, it needs a 10mm gap, however great minds think alike and all that, I have been looking at 30 x 30 aluminium angle to bolt onto the side of the fence as I posted about three back, unfortunately there is a raised lip on the edge of the fence so it would then need two 1/4" T tracks to take the JessEm track, alternatively fix the JessEm track directly to the new angle fixed at the height of the lip and pack up the other side to suite, either solution will work, but does make the right hand side of the fence unusable, not that its used often anyway, I also had a look for plastic strip at 30 x 60 to be full height of the fence, but it is extortionately expensive, of course I could buy a new fence, but that is a bit of a drastic (expensive) step just to get the guides to fit especially as the current fence is perfectly adequate.

Hi Mike,

As you know, i've also been considering how I can get the jess em guides to fit to my fence.
I'm seriously considering attaching a aluminium profile to replace part of my fence so I can simply slide the jess em guides into it, heres the link to the company that sells an enormous variety of profiles in different sizes / styles

http://www.aluminium-profile.co.uk/acat ... _Slot.html

I just need to check what depth the t slots are as its not listed on the drawing.
For the price of the extrusion I think it would make a much better fence as you can add jigs, hold downs etc just by sliding them into the many t tracks.
Hope this helps you

 

[MikeJhn]

Thanks for that, I have seen them and they present their own problems, mainly width and position of the slots, looking at the instruction manual for the guides, the fence side of the JessEm guide edge needs to be 20mm from the fence face to allow the guides to be parked above the fence face when not in use, this I see as essential to allow full depth use of the fence, without removing the guides themselves, this requires a fence that is 70mm wide to accommodate the parking space and guide and an offset fixing for the JessEm guide track, I am probably going the aluminium angle at the raised lip height and packing on the fence route.

[Adam9453]

Thanks for the extra info Mike.
Something i've been thinking though is that assuming your max depth of cut is 100mm then providing your fence is higher than 100mm, the wheels shouldn't ever get in the way (as the wheels would always be above the max thickness of timber you'd be cutting).
This obviously wouldn't work if you were doing trenching cuts on thicker timber (as that could be over 100mm) or if you were cutting thicker timber by running it through once and then flipping it over to complete the cut.
Food for thought though

 

[MikeJhn]

Except that the maximum depth of cut using the guide is 84.861mm (3.341") from the top of the fence see page 7 here: http://www.jessem.com/assets/04301---cl ... guides.pdf plus the depth of your stock, with my fence at 60mm this restricts the depth of overall stock I can cut, that is why I was looking at putting T track on top to increase the depth it can be used on, but then you go full circle with the depth of stock it can be used with, also why I wanted to be able to park the wheels out of the way.

Trenching cuts don't concern me as I use my router for that operation.

Mike

 

[Adam9453]

Ah I see what you mean, it would be ideal then to have two different height fences to give you a full useable range of depth of cut. This I think certainly pushes me more towards the extrusion system as I could get a couple of different heights, or perhaps add on another extrusion to increase the height of the fence (stacking them).
I've seen some other guys setups using the extrusions and it looks incredibly versatile

 

[MikeJhn]

There are certainly quite a few different profiles to choose from, in fact there are a few which could be used to replace the fence completely as long as the space on either side of the T slot is enough for the guide to sit on, yet another way to divest the feline of its outer coat.

Just thought the only problem I see with the extrusions is that the JessEm guide sits over the T track, you would need to ensure there is enough support on either side of the guide itself and obviously the knurled bolts would not be long enough for the slide (part No 5 & 9 on page 4) unless you where going to mount the JessEm track directly to the extrusion and not use the built in tracks.

Mike

 

[Adam9453]

I just had a closer look at that PDF you mentioned, I hadn't realised the guides effectively straddle the raised section in the middle. I was hoping to mount the guides straight to the extrusion to avoid having to use the jess em track in between.
However one of the issues you raised about mounting the guides to the extrusion would be lack of clearance from fence face to allow the stock guides to sit out the way. But because the mounting holes are to either side of the jess em track (rather than down its centre) you could therefore mount it offset which may create enough resting space for the guides. My concern would be not having any fixing into the holes on the other side of the jess em track which is what I think you were referring to earlier.
Hmmn how best to do it?

 

[MikeJhn]

I have ordered a 60mm x 30mm x 3mm aluminium angle that I will fix to the offside of my fence, this will increase the width to 70mm, the JessEm track will be fitted onto two INCRA 1/4" tracks and in turn these will be fitted to my extended width fence, this will increase the height of my fence by the depth of the INCRA track and still be within the range of the guides whilst allowing the pressure arms to be parked on top of the fence out of the way when required.

The instructions for the JessEm guide instruct on how to mount the track on one side only, this induce's a horrible cantilever to the track which I did not like the idea of.

Mike

 

[MikeJhn]

I ordered the stock guides and they arrived yesterday, (Thank you Peter) on opening the substantial packaging I was impressed with the quality of the manufacturing, the guides slide on the fittings as you would expect from a well machined tool, waiting for the rest of the fittings I need to fit on my fence, all due to it not being dumpy like our American cousins. :wink:
