Fostex FF85K in the Buschhorn Mk I?
 
Has anyone ever tried putting the Fostex FF85K in the Buschhorn Mk I enclosure? It looks like a relatively easy build, and the FF85K seems to be approximately the right size. The plans for the enclosure can be found here:

Worth a shot... but if you are interested i have 2 different upreleased Spawn horns for the FF85 that it wouldn't hurt having proto-typed. email if interested.

Hi, any chance of a copy of the plans. Email sent

It appears I've gone and cut a bunch of plywood into strips. When I chop the pieces to length on the mitre saw, is it important to try to make some of the smaller angles? For example, pieces E, F and G all have angles of less than one degree. I don't think I can cut that with any kind of accuracy on my saw. The 10.6 degree acute angle at the end of L seems like it will be tricky, too.

You'd need a tenon Jig to cut that angle... or do an Ed Schilling.

Is this a tenon jig?

That would be the equivilant for a mitre-saw. I think a tenon jig is for a table saw.

for a quick and safe method of cutting the bevels for the angled deflectors I'd use Delta/Porter Cable 34-184 tenoning jig (let google be your friend and take you to a review / tutorial on this great little gadget.)


OnlineToolReviews.com - Delta 34-184 Universal Tenoning Jig Review

while this tool is designed to firmly hold the workpiece at 90deg to the table saw top, there's no reason the blade can't be tilted


of course for you could build a wooden jig to accomplish the same purpose, but there are some tools on which it just pay to splurge (particularly if you can amortize the expense over hundreds of pairs
:rolleyes:)


anyway, in this case you set the bevel cut on your table saw to the more obtuse angle needed on the deflector (30deg on the saw's bevel gauge), and make the first cut the "normal" way, then leaving the bevel angle, install the workpiece in the tenoning jig and cut the acute angle.

Even if the blade setting is off a bit, you'll get a perfect fit between the front and bottom panels of the cabinet

speaking as a man who only has access to hand tools, including a circular saw, I find that a hand-plane plus a wooden block and some sandpaper allows a high degree of fine tuning when it comes to this kind of stuff !

Silly question... a web search turns up far more results for the Buschhorn MkII, and relatively few results for the original Buschhorn design. Any thoughts as to why the MkII is much more popular?
