I hope this is at good place for this since it pertains to machining and is not intended to detract from this site and is not commercial in any way. But I believe this may be of interest to some members: Southwest Michigan Home-shop Machinists The Southwest Michigan Home-shop Machinists group is ope...

Re: Resin for patterns?

Thanks for that tip. I have gotten their catalog but didn't notice those (not in the market at the time). Trainman4602 also has videos I came across demonstrating Repro casting resin from Freeman supply. I wonder if West System epoxy would work. I have a west marine in town and in fact still have so...

Resin for patterns?

I seem to remember something about making copies of a pattern by casting a "negative" and then pouring a resin into that mold to make new patterns so I can cast multiple wheel (or whatever) in one pour without making extra wood patterns. I can't seem to find names and/or sources for those ...

Re: Starrett Last Word

I've got an old Last Word I've used for years. Dates from before 1980 but not sure how much before; I got it used. It works. Maybe being a home shop machinist of dubious talents precision hasn't been so critical as for some of you. I did notice recently that I might be getting some hang up with it. ...

Re: which CAD program is good for live steam modelling?

After Bill mentioned surfaces I thought I should throw in that Vectorworks, while it does have some stock "solids" tools like cube, sphere, etc., it also works with surfaces (they use the term NURBS but I don't know if that is a trade wide term or their own). It is mostly that surface mode...

Re: which CAD program is good for live steam modelling?

I use a CAD at work from Nemetschek called Vectorworks. I haven't extensively explored the 3D capabilities but I have messed with it some. It seems like it should do a good job and I think they are upgrading and positioning themselves to be competitive with things like Solid Works. I mostly use 2D b...

Re: Kozo locomotives

Woops. I think some of you took it that I felt flamed in some way. Not at all. I wasn't even intending to be "defensive" of my viewpoint. I was just sharing my direction or purpose for working on a locomotive and I may have gotten a bit long winded. As Harold says, none of us is right or w...

Re: Kozo locomotives

.... As much as I hate to say it....but if the cost of basic materials involved in building the loco is slowing you down - then perhaps maybe you should think about something else. ... And people like me are probably why you hated to say it. :o I would argue that if one is trying to get on the trac...

Re: Kozo locomotives

I can't answer the question of how long it will hold up in terms of the rust issues mentioned. I can say that it works. I am building my Kozo A3 out scrounged materials. I used the copper and brass for the tender tank as designed because I didn't want to mess with coatings inside the tank to prevent...

Re: I made an Allen Head Bolt.

I once needed a square key for the beat adjustment on an old pendulum clock. I used a mild steel shank for the key with a knurled knob on one end. I made a square bit, just slightly bigger than the clock shaft out of some O1 and heat treated it. After drilling the end of the key unit to roughly the ...

Re: Plastic Parts for Microwave Oven

I had the same problem. I tried acrylic not knowing how hot things got down there. It didn't work. Being cheap, er, I mean frugal, I wondered about metal. Since the bottom of the MW oven is metal and this part is halfway through the hole in the bottom I thought I would try it. I used a hunk o' alumi...
