Currently in the process of building a small bass body out of walnut. I'm looking-around for anyone that may sell a compact rear-cavity routing set.
StewMac sells a set but it's a taste on the large side for what I need... http://www.stewmac.com/Luthier_Tools/Types_of_Tools/Routing_Templat... (it's almost 8" x 3.5" or so).
Last week a Samick guitar was in for some work and the control cavity cover was a nice size, being only 6" x 3.5" so I traced it just to have a reference.
Anyone got an idea of where to source a set similar to this?
Hi Andrew. Oh yes, I know the theory.... it's my execution that always seems lacking :)
Making a one-off isn't too bad, but trying to custom-make a cavity cover plate that nicely matches the custom-made cavity is where it all usually falls apart for me.
Maybe I'll give 'er a go. If it goes south, there's always the StewMac version but, dammit, they get plenty of my money already!
Use this method all the time. Works quite well; just rout the cavity to your liking, making a rabbet to screw the plate into, and tape down your paper over it for the pattern. Rub the pencil over the edge of the opening. It will make a darker line where the edge is.Tape the paper to the plate, or rubber cement it, and cut out. I make them just a fraction oversize and trim with a sanding plate a bit at a time.
you can check at www.
bestbassgear.com (or something like that). They carry a lot of templates.
Thanks, Mario.... I checked with them and (while they do carry many templates) they offer nothing for rear cavities, but I appreciate the thought :)
Gonna' bite the bullet here and do a "from scratch" one-off. It'll require making 3 items: (1). a template for the interior cavity. (b). a slightly larger template for the recessed flush cover and, finally (c). the cover itself.
The search, however, tells me there could be a market for this sort of thing. CNC'ers, take note!
I start by making a template that's 1/4" bigger all around than the cover I want. Then using a 1/4" bit and a 1/4" template guide, I lay the template on the material and cut out the cover. Then I lay the template on the surface the cover is to fit on and using a 1/2" template guide route the "lip" of the cover recess to a depth equal to the thickness of the cover. Then without moving the template, I switch to a 3/4" template guide and route the cavity to the desired depth. One template works for all cutting. And the router cutter remains the same. Just the template guide changes. The template guide is just a collar that fits into a router base - they are available in a number of sizes.
Thanks, Richard. See, here's what an idiot I am: I had no clue that "template guides" existed.... are those the brass collars that come in sets? Pardon me while I slink out of the room.
Yikes, it may be time to return to remedial "Routing 101".
What usually works best for me is sleeping on a problem. So, after mulling-over all the good advice from the troops, the "light bulb went on" regarding Richard's use of template guides and only needing a single template to rout the cover, the recess and the cavity with just one template... it's brilliant.
Made my template this morning (with hole saws, rasps, small sanding drum, the kitchen sink, etc.) and now I'm waiting for Amazon to deliver my set of brass template guides... $23 total.
