Throttle plate reamer and bushings

Can someone help Me find out where I can buy A reamer and bushing kit for Holley baseplates. I know they are out there somewhere. Im rebuilding a Ford FE Tripower set up and all the carbs need bushed. Anybody ?--Feder

 

You may be able to buy bronze bushings close to the right size at Bearing Houses.
Even if you found the exact size bushing needed, once they're pressed in place the ID comes down a little bit.
Not too big a problem with a carb bushing, but once you get up to say .750 and larger with a somewhat thin bushing the ID will come down and it will require reaming.
Carb bushing reaming is necessary for bushing parallelism so the throttle pivot turns freely and doesn't rattle or leak air.

Bearing Houses are a remarkable source of supply for hot rodders.
One fr'instance being, you can't buy Vega steering box seals at GM or Mullins, but you can get a more than acceptable substitute at a Bearing House.

Far as the reamers go, you can buy reamers in just about any size you require from MSC.
(Manhattan Supply Co.) a machine/tools supply house with about a 4000 page catalog. (4K is the right number.)

If you have access to a lathe with toolpost grinder or can buy drill rod - a water, oil or air tempered metal rod - in the proper diameter you can make a D reamer.

Grind a very shallow angled point on the cutting end to make entry into the bushing easy.
The major OD of the reamer remains constant all the way.
(Shallow angle point being somewhat similar to a typical twist drill bit.)

Then cut and grind to the size required.
Once you have the drill rod OD down to the proper diameter you grind a flat on the side of the cutting end.
Said flat maybe 1/2 - 1" long and taking about 1/4 - 1/3 of the diameter away.
Hit the flat with a stone and make sure you leave the angle left by the flat grinding very sharp.
What you'll end up with is a very accurate, easy to use, self-guiding reamer.

Somewhere in there you need to grind parallel flats on the non-cutting end so you can turn it with a wrench.
As well as run it through the hardening process.
Although for reaming a few brass or bronze bushings, hardening is probably not necessary.

 

I don't know if they will work, but Speedway has oversize throttle shafts for 94's. They use a 9/32 hole. I assume your talking about throttle shaft holes.

 

that reminds me,gotta fix that tool-post grinder project of mine,right after i finish the polishing rig i haven't started yet Jay,do you ever hang out at www.homeshopmachinist.net or www.practicalmachinist.com ?

 

Check Charlie Price at Vintage Speed.

I know he is slow with complete intake systems, but parts get shipped pretty quick.

I searched his site for rochester stuff, but know there is a holly rebuild section too.

Yorgy, used to have a subscription to HSM magazine and bought a lot of their specialty books.
Still have quite a stack of the mags.

There's an amazing amount of info in the mags and books.
Of special note is Canadian Guy Lautard.
I have several of his books.

I haven't been to the Internet sites you mentioned.
I'm keeping busy enough with the HAMB & RRT and the bi-monthly FSRA site.

Gotta get some garage time in, ya know?

Far as the tool post grinder goes, one of my ex-bosses, a home machinist guy and a pretty good one knocked out an entirely suitable tool post grinder on the cheap.

He took a piece of 1/2" aluminum, bent it up at about a 20-30 degree angle and bolted an inexpensive 3 or 4" grinder to it.
The whole shooting match then bolted to the compound using a shoe/key in the slot and a big bolt & nut.
It was a goofy looking thing, but very solid and he turned out some nice work on it.
