Been working on a drilling jig for the last couple of days. Had a few issues with the older one and thought that having one jig that could do the job without being repositioned would be a time saver. Then, was wondering if the model could be reproduced in a 3d printed plastic mold, with steel collets of course. I've had a jewellery box kit for about 7 yrs now and haven't had the time or the inspiration to complete it, so having some finely milled African hardwood I went ahead and made the jig knowing that the collets (bushings) wouldn't break out of the timber, being of a wood that didn't split unless it was weakened. So, after the product has been finished with the appropriate bolts and wing nuts, is there a chance of getting the final model laser scanned and 3d printed?

I like it Paul, I use an old doweling jig, but it only does 1 hole at a time, and each hole has to be manually lined up.
Can't help you with the 3d printing, but did you know our library has one? Yoyo was going to do the course, don't know how he went.

Yeah, he's doing the course and the jig will fit into the confines of the printer he's got access to. No pressure dude

Good stuff. Nice work bench.

Pepe, contact Nebian, I believe he has a 3D printer.

Pepe, beautiful craftsmanship as always.
I like your attention to detail.

Pepe, +1 WindX's comment and I would dearly love be able to concentrate long enough and hard enough to match your workbench skills but......I just couldn't help noticing the scissors were at a rather untidy angle and the Allen keys....well, I'll pretend I didn't see them.

That mirror glaze works a treat on beetle shells

I have not one but TWO 3d printers

If you can measure it up and either make a drawing or take photos from a variety of angles then I can print it. Looks easy enough.

I've even got some fins to make it fit against.

What diameter are the holes for the collets?


P.S. Your workbench is ridiculously clean. I'm sure Decrepit would agree.

Pepe doesn't criticise my messy workshop, far be it for me to criticise his tidy one.
But it sure is clean!

Something like this?

(Had to guess at the hole sizes)

Wow, nice work Nebbs. Having some trouble sourcing the bushings atm, but an 8.5mm hole in the top for the 6.5mm hole allows for a bushing with a 1mm wall thickness for the 6mm fin bolt. And the barrel nut hole would be 5mm, which allows a 3mm (pilot) hole so you can use either a 12 or 9mm barrel nut. The barrel nut hole is better if it's drilled with the press drill (stable).
I have yet to drill the clamp holes, but that looks right on the money Nebbs.

I assume the through bolt holes are 6mm?

Yep, that's right. A 6m clearance.

Prototype printing now. Be interesting to see how far off I was, I had to eyeball the angles because my angle finder's battery was flat.

You guys just amaze me sometimes

Only sometimes Firie????

Great shot Nebs. The image in my head of your 3D printer was a bath of goo, with the object coagulating inside it. But I guess that's not actually a printer, some other sort of 3D thingo?

Decrep, yep that's another form of printer but they (and the goo) is expensive and messy. This one uses a roll of plastic wire which it heats up and melts onto a flat plate.

Here's a photo I took just for you, you can see the big black roll of filament on the left hand side.

Hey Nebs has Pepe shed shamed you into spending some quality time cleaning up your shed before the photo?

No, my shed always looks like that! Erm... yeah.

You should see my desk

Thanks Nebs, did you make it yourself?

I didn't build this one, but I did build my other one and have rebuilt this one with several improvements.

Well we have proof of concept, I was a couple of mm out on the back of the fin so had to dremel it out a bit. I'll adjust the model for reprinting.

For drill bushings you can get roller bearing inner races from bearing suppliers like bsc, cbc, statewide roller bearings also make good dowel pins rudd industrial sell dowel pins and some bushes nice printer nebian

Thanks Piv, I'll give them a try.

Second time's the charm. Fin fits nicely, 1mm of fore/aft slop with a couple of the fins I tried, enough to be sure that you're seated fully at the top of the box. Also 1mm clearance between the two halves to ensure that the fin is clamped down firmly.

PM me your address and I'll send them to you for testing (they're no good to me!).

Awesome effort there Nebbs
Just pm'd you, I'll have to send your stubby holder back that you left here about 6yrs ago too

Stick a ginger beer in it

This is what you need Paul. Forget about bases , print the whole thing



Titanium 3D printed fin (51knots in kite board) Design Phil Carbon. Made in France with DMLS. Thickness 0.4mm !! Which is OK if you don't mind a scalpel on the bottom of your board.

So how did the jig go Pepe? Anything I need to tweak?

Hi Nebs, Paul is back at work now but I think it was bit flimsy for him...he is more the "machined from solid billet" kind of guy. :-))
