Re: combination welders

Even Lincoln has different grades. If you look up the 140 MIG for example, there is a wide range in cost, and performance, about five steps in that series. Might look for a good used machine, I have had good results there.

Re: Cylinder castings

Random thought; Electrical utility boom trucks have non conductive hoses so an accidental contact with the line will not result in a bad event. Might mention that to the hydraulic supply place and see it they know what is supplied for that application. I know some hydraulic hoses are made with non m...

Re: Bridgeport as a drill press

I also suspect that the local shop is not too much concerned with longevity. These machines are in the run until they drop phase, then go get another. Lot of stuff in their shop in that mode.

Re: Bridgeport as a drill press

The local machine shop has two Bridgeports heads in production drilling of 5/8" holes in 1/4 - 3/8 thick steel. Full sized bit, no pilot. They use hand feed and drill holes as fast as they can feed the stock to them on rollers. May not be designed for it but they are making holes by the thousand wit...

Re: Capabilities of a 12" lathe

Support at both ends, you will be glad you did. I have done several similar objects, bolted to the faceplate at one end and some form of spider at the other end. The extra support is essential for stopping chatter.

Sure, why not. I might be able to glean a few bits or I might find someone local that knows German. If it can be sent by pdf, I would appreciate a copy. There might even be some online auto translate functions that could get most of the words.

Thanks.

Re: Angle Grinder Rant

I have at least three of the Dewalts, sometimes cheaper by the two pack. No problem with cord length, after it gets knicked or chopped, jut put on a new plug - happens soon enough. The only issue I have with the Dewalts is that a couple of them sound like they have gravel in the gear box, and that r...

Re: Rubber forming, aka Guerin process

Been a long time since I saw an inner tube! What with everything being tubeless these days, but we do have several large truck tire repair shops in the area, might give them a visit. Interesting video, not impressed by his ram tip alignment though. Thanks for the link. Would not have thought of a sp...

Re: making a cast iron riser block

A coin toss? Cast might be better but will certainly take longer. I have had no issues with the steel riser I made. Might be worth a visit to the foundry, and as you suggest, might have a suitable lump. Probably will take a pattern and a core box as you probably need a core through the middle, less ...

Re: Rubber forming, aka Guerin process

That is close to what I am thinking. I have a 40 T press and was thinking of building a 6" x 12 box and putting 2" of rubber for testing. I need up to 1" of depth on the parts, but no tight edges.

Re: Rubber forming, aka Guerin process

I have gleaned a suggestion of 60-70 durometer for the rubber from one vender's site, and I have a source for the proper rubber. Not that expensive so I probably will get some bits and start playing. Fortunately the pieces are for wind sculptures so there are no required tolerances.
