Re: Bridgeport 2J head variable speed to direct drive???

I bought a 2j cnc Bridgeport for $400.....guess what? It's missing the variable speed top assembly.

So, I'll be tinkering with putting a step pulley assembly on it.

:D

Re: Live Steam Business assets being sold piecemeal?

$9000 for tooling to make bells! How many bells do you have to sell to recoup that cost!

Makes me think that I should make molds and patterns.

Re: 3-3/4" scale Sunbeam turbogenerator castings

A friend of mine has a set......they are very nice.

We were looking them over the other night to form a game plan to machine them.

Re: Bridgeport 2J head variable speed to direct drive???

I've only replaced the thin bushing on the moving cone pulley.

So far, this one has lasted a year. It's louder than it was, but I think it'll last another year.

Re: Bridgeport 2J head variable speed to direct drive???

I'm also wondering if I can just take the whole top assembly off and replace it with a regular step pulley assembly from a J head.

I have a couple J heads collecting dust that I could use

Re: Bridgeport 2J head variable speed to direct drive???

After thinking about it more.......I don't like going direct drive. I think I would just rather replace the variable cone pulleys with timing belt pulleys.......then just use the VFD to control the speed. I typically use a range of 700-3000 rpm. I don't need a lot of torque as it's a cnc Boss and I ...

Re: Bridgeport 2J head variable speed to direct drive???

First I would investigate why they are making noise. I can't imagine all of them do that, or we would have heard more about it. When you say bushings, what bushings are they? Is the belt tension too tight and the tension puts too much side pressure on the bushings (like too much tension on your car...

Bridgeport 2J head variable speed to direct drive???

I've been curious if anyone has converted a variable speed bridgeport head to direct drive or to just regular pulleys or timing belts. I have replaced the belt and bushing on my mill twice in 3 years. At first it's really quiet, but soon becomes louder and louder. I'm thinking that I could just do 2...

Sold : 12 Alco PS-4 Drawings $50 obo

Cleaning shop: found a stack of Alco PS-4 drawings. These were originally purchased from either Rogers-Cooke or Klamath. I was under the assumption that they sold scaled 1.5 or 1.6 drawings so I sent them a check and what I got was prototype Alco drawings. They've been sitting in a drawer ever since...

Re: HGR industrial surplus. Euclid Ohio

They used to haggle more. Now they have a system set up so they don't budge on prices until it gets marked down....then the more it gets marked down, the more they haggle. I bought a really nice ratcheting Dake press for $180 last year. Two 6" kurts for $250 the year before. Two cnc Bridgeports for ...
