Title: Custom Metal Venturi
Post by: Bill Sawyer on December 23, 2010, 12:16:06 AM

I know several people make venturi out of delrin or other plastic type material but I would like to get some metal ones - just because I like the looks. Does anyone make these to order if I supply the measurements?

Hi Bill,

I have gotten metal venturi from Randy Smith, Leonard Neumann, Jim lee, and Byron Barker over the years.  Most use delrin for ease and cost, I *think*.

Probably anyone who makes then would do them in metal but they will cost more, I'm sure.  AS to ones who "only" use metal, I don't know.

Merry Christmas!

I made one for an OSFP .15 once outta the end of my exact-o knife. Did it in my drill press. A drill press is just a vertical lathe LL~ ;D

I've used a piece of brass pipe with 3/8 OD and 9/32(or .281) ID I put it in a drill and filed part of it to fit the engine then flared the other end with a dremil.

Heck, I've made venturis out of Maple.  Works fine, as the venturi is just a means of metering the airflow.  Did use the "vertical lathe" or Drill Press to you, John.  How's that for thinking totally outside the box?

I think we may be hyjacking this post but did you coat the wood with anything?

Bill, Leonard over at SSW makes custom metal venturis.

I guess I am partial, but have several of Jim Lee's venturi's of different sizes for my LA engines.  Even have a thrust washer for Green Head K&B .35 Jim did for me.   H^^

Do any of these guys accept paypal (I'm in the UK) for payment as I need one for my os 35s. I don't mind if its plastic or metal just as long as it includes the NVA
