« Part 2: Leaf springs Part 3 of The dump truck series Part 4: Rear spring mount »

To make the axis holes fully parallel I made a new jig. I had seen this jig here at LJ but can’t remember where. Sorry! My own conceived jig was much more time consuming. I make the hole 8,5mm over the full length. This makes that the 8mm. dowel can turn in the axis.

Great jig; I do have trouble getting long holes truly square, with what they are supposed to align to.

I like the jig Dutchy, I usually clamp the timber in an engineers vee block on the drill press table….
You idea is so much simplier, thank you….

Very simple, effective and repetitive jig Dutchy. I’ll need to borrow that idea for sure. You would be wise to have a backer where the drill bit comes through so there is little or no tear out from the drilling process.

Thanks all.

Crowie: As said before the jig isn’t my idea. I saw it here at LJ.

Roger: I’m drilling from both sides. First with 8 mm and then with 8,5mm. Besides it is drilled in endgrain wood, what means that there would be (almost) no tear out.

Looks like this is going to be a fun project for sure!
Didn’t realize these plans would have springs,and looks like a drive shaft in the plans now that’s cool.

I like your jig Jan and also your logic of centering the hole by sanding after drilling.

I have been making long wood hinges for my boxes with a hole all the way through the length (about 8” long). Impossible to drill through (for me at least) so I route a half hole in to long pieces and then glue them together. The glue joint is almost totally invisible providing that each inside half is made perfectly flat before routing. I do that on a sanding board. The grain is well matched by rip cutting the two lengths from one piece and then gluing them back together in the same orientation.

Thanks for your comments.
I had a nice conversation with Bruce AKA htl over drilling long holes. I think very interesting. You can fine it here

Jan, I forgot to mention that after gluing up my hinges that I turn them round on the lathe afterward.

I found Bruce’s technique interesting, but I think I still prefer my own method as I can make any size hole I want with the router and it is very fast and the whole job of sawing, flattening, routing, gluing and turning goes quite fast even though it involves so many different operations. One advantage is that I can make a piece almost a meter long if I want and then cut several 20cm hinges or dowel lengths from that one long piece. I think that can be very effective and also very accurate.

You blatant cheat in centering is brilliant. I still envy your sanding disc techniques/expertise.. Please tell me you use jigs but have hidden them..

Alex the only jig I use is the one on picture 2,3,4 and 5. I put a long dowel from about 40 cm through the axel hole. Than it is easy to hold this dowel parallel to the disk. The wood with remains besides the hole is about 3-5 mm. For me this is easy to estimate. Hope this helps.
