Re: Steam Turbine Question

My first guess would be that the expansion due to the heat from the steam is causing it to bind up somewhere. Was it technically made for steam or just a model of a steam turbine? Expanding steam can get a turbine spinning real fast, this being brass makes me wonder if it was ever intended to be pow...

Re: Mark Gregor

This is the first I had heard of his passing. There was talk about some of his equipment being for sale of recent but no explanation of why. Lee Wright was a good friend of Marks and he built quite a bit of Marks equipment and helped on building his railroad. Hopefully someone will come along with m...

Re: "Mounting a square piece between centers

If you have a mill I would set up the piece and indicate it in and then center drill, repeat other end.
Or if you have a collet set up there is always using a square collet.

Re: McMaster carr part number

I have always followed the rule that if you have a 5/16 injector, run 3/8 lines up to the injector. 1/4 injector go 5/16 lines. The larger the water supply lines the less effort it takes the injector to draw water in.

Re: McMaster carr part number

I would assume you are looking at the paper catalog? Going to their website and doing a search for copper tubing brings up their selection guide on the left side of your screen. 5/16 o.d. tube will be 8967K59 for straight non bendable, and 8955K241 and 8955K251 for bendable coils depending on which ...

Would that be like laying 96 GE44 HO engines put end to end and be the length of a real one? :shock:
nope

but if you put 87 end to end you would get real close to the prototype length

Re: GE 44 tonner

If HO was 1/96 scale then 1/8" to the foot would work, but HO is 1/87 scale or 1 ft equals .13793 of an inch. 2.5 inches divided by .13793 equals a multiplier of 18.125136

Re: GE 44 tonner

In HO one foot equals 87 feet or 1044 inches. In 2 1/2" scale one foot equals 2.5 inches.

If we take a 120" in HO scale that comes out to 1.379", the same 120" in 2.5" scale comes out to 25". That looks like from HO to 2.5" scale needs a multiplier of 18.129.

thoughts on makerbot replicator plus

not that I was even looking for one but I run across an all but new Makerbot replicator + that I could pick up pretty reasonable.

Just wanting to get some thoughts on it, are they decent machines, pro's, con's, run away, etc.
Has anyone on the group used or own one ?

thanks

Re: Cinti ToolMaster 1D variable speed pulley & motor shaft ?

Back when I was dealing with Parts n Parts the sales guys all quoted me ridiculous prices. The main thing I needed was the lower quill housing as the retards that had the mill I was working on had for some reason taken the head apart and lost pieces. I was quoted about 3K for what amounted to the lo...

Re: Ceiling tile for my shop

You need to look into thick aluminum faced tongue and groove insulation. About 20 years ago a friend built a 36x54 pole barn and as it came up towards fall the first year he started looking at insulating and getting it ready for winter. We have an insulation dealer that handles alot of "seconds" abo...
