Alignment Problems: Veritas Router Base Plate / Table Insert
Well, it looks like I'll be one of the ones needing a second base plate
sent to me. I just finished installing the plate on a PC690 and it was off-center by just enough to make the 1/4" insert not fit around my 1/4" straight router bit. Poor eyesight and shaky hands played a large role, I'm sure. However, I'm wondering if there's a better way to skin this cat... (Disclaimer: Not my idea.) What if I somehow clamped the plate and the 1/4" insert to the bottom of the router and then lowered a chamfering bit into it to pull things into alignment and then (somehow) was able to mark the base plate through the existing screw holes in the router base itself? Has anyone done this? Does it sound feasible? I googled a bit but apparently not enough. Thanks all, I'm going to bed so don't be miffed if I don't respond immediately to your replies if there are any. JP |

Well I went ahead and drilled a second set of holes in the same plate today and it's now fully functional. These are the steps I took... 1. Put the 1/4" insert into the stock Veritas base plate. 2. Put a piece of clear packing tape roughly over the areas where the holes to my router would be drilled, the idea being that it would be easier to pierce a piece of tape than it would be to mark the base plate itself. 2. Put a 1/4" straight cutting bit upside down into the router, such the entire cutter and part of the shank was inserted into the collet. 3. Taped a single wrapping of celophane tap around the 1/4" shank to provide a snug fit. 4. Placed base plate flat on two 3/4" supports and then put the router body onto the plate and the bit through the 1/4" insert. (I had to be careful not to let the insert push down the tape on the shank of the router bit.) 5. Took a drill bit just small enough to fit in the threaded holes of the router and spun it by hand to pierce the packing tape that had been put there in step 2, being careful not to spun the router relative to the base plate. (I suppose I could have clamped it, but I was worried about deflection.) 6. I used a sharp punch to enlargen the pin pricks in the packing tape and to make a mark in the base plate itself to keep the drill bit from skipping. 7. Drilled the holes the appropriate size for the machine screws. 8. Countersunk them. 9. Attached base plate to router. 10. Celebrated! This method seems to have worked, and it honestly didn't take much longer than the method that Lee Valley proposes. If I were extremely anal I might have chucked a few pieces of appropriately sized threaded rod into a metal lathe and ground accurately centered points on the end. At that point I could have simply threaded them into the holes of the router and slid the base plate with an insert in it onto the router with an appropriately sized piece of round steel. That would be extremely simple, and very accurate. |

That would be extremely simple, and very accurate. The more I think about this, the more I believe this could be a very simple upgrade to the base plate package itself. Rather than fit and mark a (flexible) mylar sheet and then transfer it to the plate itself, you could directly mark the plate itself. There would be just a couple of changes. First, you would substitute a centering device sized to fit the opening in the base plate itself, rather than the hole in the mylar sheet. Second, you would include three pieces (for a PC690) of threaded rod with a point on the end, and eliminate the mylar sheet. The cost differential to produce them couldn't be much and it would be a much simpler and far more accurate method. Someone please play devil's advocate for me... JP ************* Lonely. |

In retrospect I would have simply used the 1/2" brass insert I
purchased, plus the included 1/2" "bit" that LV included with the base plate. The new plate did arrive so perhaps I'll give it a go this weekend. JP *********** Blogging? |
