LR-32 disappointing
« on: February 15, 2021, 08:21 AM »
I recieved my LR32 router sled and rail the other day, 3 points to note.
The two plastic blocks on the base of the sled have two rivets each to secure them. these rivets stick out proud of the plastic blocks by about 1mm so will mark the work piece.
The sled is covered in sharp edges where it has not been deburred after guillotine/punching.
with the sled adjusted for zero play on the rail once the spring loaded pin has engaged in the rail i measured using a dti 0.3mm of play whilst moving the sled back and forth along the rail. for a £500 system i would not expect any of the above. the guide pin in my opinion should ride in a bush to keep it perpendicular and also would be more accurate than a punched hole

does anyone else see these issues?
cheers

I believe the 0.2/0.3 mm play is intentional - it is considered "acceptable accuracy" for the purpose and is needed to allow the spring system to work at a good productivity. Otherwise it may not have time to "drop into the hole" while moving the sled. The whole point if the system is you do not have any "compound error" effect as all your holes are referenced the same way with the inaccuracy being constant and within acceptable limits.

Yeah the rivets on mine were fine, but I still filed them a bit. You may want to put some non-stick tape on the plastic support, as it is a bit lower height than would be optimal in my experience. I raised mine by about 0,5 mm.

one application i have in mind is to make to top for an MFT (96mm centres). there is a very interesting youtube of a chap routing the 20mm holes for whole top in 7 minutes using the LR-32 system.
So for this reason i would like better accuracy. maybe keep the sled pushed one way all  the time to remove any backlash?

Not LR-32 but...that's the same method I used with a Woodpeckers setup, I just biased the tool/fixture in the same direction for every hole. With a distance between the first hole and the last hole of 1050 mm (41"), the last hole was out of perfect positioning by .5 mm (.020").

The rivets on mine definitely do not stick out. No sharo edges either. Accuracy is fine. If you push hard enoug on anything.. it will give that 0,x mm

With mine only the pin is a bit too long so it punches the panel.

I added foamtape in between the gliding pads to improve dust collection when drilling the 35mm hinge holes.
