Same here - no audio problems when I play it. Paul

Nice thought! I'm sure he will appreciate the effort and time you have put into this. Paul

Jamie, Very nice implementation. Excellent quality - boy I have a lot to learn! Paul

Lots of great info in this post. I saw you used a jewelers saw to make a cut while the part was chucked in the lathe. Do you cut off the part with the lathe rotating? Also, where do you get shellac of the form and type suitable for making you shellac chucks. Is this dry shallac flakes? These...

Ditto's here on Draftsight. I have been using Autocad (2D only) since the earliy 80's. When my version of ACAD would not load on my latest OS, I took took out several test drives on various "lookalikes" and quickly settled on Draftsight. Since I have used ACAD when it had only a command line...

LuBo, Magnificent piece of beautifully finished machinery. I imagine you have quite a few hours invested in it. Keep up the great work and keep on posting. Paul

For non-ferrous materials, you can also use a good ol miter saw made for wood. I have an older Black and Decker I use. Outfit it with a Freud carbide blade from Home Depot - the "better" or "best" grade - not sure which, but it is marked for use with all non-ferrous metals. It cuts like butter...

Your finishes look like mine did when I got starting a few months ago. My problem was mostly a poor tool - I was using a cheap carbide tool. After grinding a HSS tool, things started to get better quickly. Keep it sharp and approach the part with the front of the cutting tool only 5 or 10...

Did you never get this running? Paul

Thanks for all the great ideas. I have to make 4 of these. I am building Jan Ridders LTD Stirling "Nicole" http://heetgasmodelbouw.ridders.nu/Webpaginas/pagina_ltd_stirling_met_cds/cd_dstirling_frameset.htm. I think I will part them off, then go with KVOMs home made collet where I can finish...

Part of your finish problem may be the raw material you are using - that stuff looks a bit stringy. What is the material? Paul

Hi all, Trying to "slice" off 0.100" thk disks from a .500" diam bronze rod and then drill two off centered holes in each - this is for my first Stirling build (my first engine build of any kind). I am a real novice, so everying is quite challenging. On my first pass, I clamped the .500 diam...

Chuck, I am new to the model making scene, and I am in awe of your skill. I really enjoy seeing your setups, as from my point of view, the biggest challenge I have in any machining operation is how to set it up/fixture it. They say that you learn by your mistakes, and if there is any truth to...

Welcome to the forum. Tell us a bit more about your equipment and your experience. Always interested in listening to newcomers and why they are moving into model making. Me, I'm an electrical engineer who is addicted to learning new skills and new technology. Just got started in model making at...

Interesting topic and very near and dear to me. IMHO VFDs are a double edged sword. Although they increase the speed range for any piece of equipment, they defeat one of the greatest benefits of gears and pulley systems which is a proportional increase in torque at low speeds. With any gear or...
