Gents, Ladies, Boys, girls, Jocks and Jockettes….
Someone asked how the door kerfs were made in models,

Well there are many more different methods then there are hairs on my well adorned head. Nevertheless I thought I’d pluck out a hair and say a few words on how I kerf.

Now contrary to my common practice, I’m warning you up front about reading all, in case you are not interested.

For my solution, I employ the use of SketchUp, a laser cutter (can be substituted by CNC or good scrolling practices), 3D printer (substitute a selection of dowels, drill bits and some lathe work), 3mm MDF (substitute ply) 1.6mm router bit, 3 glasses of vino and… a fast car... the fast car is mentioned just to suck in you petrol heads.

I start everything off with a SketchUp model (be nice to me… and I can make mine… model that is… available to you).

Now for example (this has been hacked together from past photos and paraphanelia…) this side of the Hummer that needs the illustrated kerf cut… Let’s concentrate on the front door and treat the rest as Christmas stocking filler,

Using the ”Offset” tool (... in SketchUp… I’m not THAT kinky) I expand each kerf in accordance with the diameter of my following ring (no… not my posterior)... again for the front door only,

This will give you an appreciation of the two diagrams’ interaction,

Now with the aid of my rusty laser… now here you can substitute CNC or a scroll saw… you will finish up with something like this (a couple of routing templates),

Now you go and rig your favourite router/trimmer with the correct following bush… and if it’s the wrong size… re-do the SketchUp “Offset” procedure. But if it is the right size, grab a 1.6mm router bit (or whatever tickles your fancy… hmm! router bits… robust fancy),

A strip of 2 sided tape (you can try one sided if you are a thrillseeker, but I’m sure you’ll double up) and rout the kerf.

Another option I have lately added to my arsenal of useless gadgets, is this 3D printed follower for a Foredom handle… (dowels, drill bits and dexterous lathe work could easily substitute for the 3D printing procedure)....

It could be adjusted for a Dremel or whatever strikes your fancy… here we go with that weird fancy again).

I just hope that this can give you some ideas and the following template could be a breeze for scrollers… and for all you non-scrollers… hire a scroller and keep employment flourishing!

Well I checked it twice and still did not understand what it was all about.
All very interesting and very well presented but sadly way over my head, I thought a kerf refers to the width of a saw blade.

Managed to get thanks though!!

This confirms that CNC woodworking is a whole different world, but interesting nevertheless.

”For my solution, I employ the use of SketchUp, a laser cutter (can be substituted by CNC or good scrolling practices)”

Ducky does mention being able to use a scroll saw [ good scrolling practices] for making these but a ton a sanding would all so come into play if sanding is play for you.

This router kit for doing this can be had at Harbor Freight. $9
Here

The router bit in this kit is very small and can break easily so very shallow cuts are a must.

Sorry rc, I keep forgetting there are people out there that are not T & J model tragics… Have added a photo at the top of the blog to hopefully explain.

PS. Keep forgetting your multi-tallented… didn’t realise you could speak Mandarin?

Switching around from one hungry language to another is very interesting but so confusing.

As usual I love your little stories that go with the description. I just had 2 weeks in Victoria and I should have made time to come and have some Christmas cheer with you. Maybe next time. All the best for the new year and keep those stories coming.

Hey #4, Mandarin is sweet and Hungarian leaves an empty pit in my (ample) stomach.

WE HFCO (Hungarian Fern Cutter’s Offsprings) ARE HERE TO CONFUSE!

So #4, do I read this right… you have long eyes (or longing eyes)? What mascara do you use… just between us boys…”

Not suppositories… I hope…

Hey Pj, you are more than welcome and maybe next time put aside 4 weeks and I can tell you some of my long stories in the flesh! Certainly beats that bloody reading (even without the red... and I don’t mean vino)!
