Re: Which Configuration Would Be Less Prone to Flex???

In the mean time, I made an additional brace that should allow me to "pre-load" the alternator. I cut/drilled/dechromed/painted the broken bracket that I had removed to anchor the back of a tie rod to a header bolt and made a bracket to anchor the front to the J-bar. I can tighten this rod and it pu...

Re: Which Configuration Would Be Less Prone to Flex???

An idler may be do-able using the bolt holes that would hold the P/S pump down by the crank. But that would be a project for another time.

Which Configuration Would Be Less Prone to Flex???

I use a 1"-wide Gilmer belt on my Small Block Chevy to run the alternator and water pump. The belt puts a lot of stress on the mounts and will tweak the alternator forward and down as the engine revs. The standard alternator set-up uses a lower mount that lets it rock to adjust the belt tension and ...

Re: How Would I Bevel a 6" Piece of 1/8" x 1" Bar Stock Across Its Length?

I made a jig of wood to hold the two pieces in alignment for drilling in the press and the holes came out perfect. I test mounted it and it is hardly visible. The angle is so gentle that I really don't need to worry about the alignment of the bolt heads/nuts. http://www.audioheritage.org/photopost/d...

Re: How Would I Bevel a 6" Piece of 1/8" x 1" Bar Stock Across Its Length?

I don't think it is a matter of a defective bracket so much as compensating for a misalignment of the existing parts. The alternator seems to have a bit of an inward cant because the surface that it mounts to (the header's flange) has a bit of an inward cant rather than being parallel with the cente...

Re: How Would I Bevel a 6" Piece of 1/8" x 1" Bar Stock Across Its Length?

No, because the back edge is curved to match the bracket it goes under and if I predrilled it then milled it, I probably coudn't get this curved edge to align perfectly. Once the metal is thin, it is a simple matter to match the back edge with the sander. Next time I will secure both pieces to a woo...

Re: How Would I Bevel a 6" Piece of 1/8" x 1" Bar Stock Across Its Length?

I made another out of 1/8" think aluminum this afternoon, though I still haven't drilled it. I used the same technique as before except that this piece was longer than necessary, so I could cut off, rather than grind down, where the ends were attached during milling. That saved a whole lot of time a...

Well, unfortunately the shim was destroyed when drilling the hole though the thin end when the bit grabbed the material and twisted it around.

Re: How Would I Bevel a 6" Piece of 1/8" x 1" Bar Stock Across Its Length?

The mounting hole through the alternator's body that the bolt goes through seems to be a bit off rather than perfectly parallel with the centerline of the engine and this is try to compensate for that. There is a slight "hump" in the black bracket between the posts that I will try to press out with ...

Re: How Would I Bevel a 6" Piece of 1/8" x 1" Bar Stock Across Its Length?

Thanks guys. All done except drilling the two holes. I clamped it at its ends using the the two medium clamp bars on one end and the two short clamp bars on the other. The difference in height between these bars is about the same as the bar stock thickness. Then I just ground down what was left on t...

How Would I Bevel a 6" Piece of 1/8" x 1" Bar Stock Across Its Length?

I want to put a beveled shim between the F-Bracket and its mount to angle the altenator outwards a bit. In its current configuration, it has a bit of an inward tilt. Looking at the photo, I want to place a 6" long piece of 1" x 1/8" strap iron between the black bracket mounting the alternator and th...

Re: Speaker selection switch, and more than you wanted to know!

Very nice. I too am a big JBL fan with L112s, modified L200/300s, Ethyl Mermans (JBL 2241 18"/ JBL 2251J 10"/Heil AMT), Altec Big Red Supers, Chartwell LS3/5As, and RSL 3600s. I built my own remote controlled (key fob) A/B/X speaker switching system, with both line and speaker level matching, but us...
