Re: Kombrink's American

Bill Shields » Thu Dec 12, 2019 7:59 am much like flying....any one from which you return and walk away from is a good trip. Very True also in the sense that every time you fly you discover something on the plane that needs to be fixed. Real Aircraft or Models for that matter. One thing nice about ...

Re: Kombrink's American

I mentioned the brakes going out on a hill. I should have stipulated the hill was at the Canton GA. track.

Actually I am very proud of the fact that the American made it to the top twice. Coming down was a rush.

This was the first time out with the full string of cars.

Re: Kombrink's American

So... The cylinder Cocks were a complete success. No more oil and water out the stack on leaving the firing bays. The EE injector works as advertised. After no problems on three runs, it would not pick up on the last run of the day. The injector was hot to the touch and steam was coming out the wate...

Re: Seeking Knowlege on the Machining of a Bevel Gear.

Rich, This figure helped me understand your formulas DSC_5529.JPG These formula are also in both volume but yours is more inline with my education level. I am looking at a 5 inch diameter gear with 40 teeth being driven by a pinion with 20 teeth. (Cutter Selection Chart identifies the 40 tooth gear ...

Re: Seeking Knowlege on the Machining of a Bevel Gear.

Both the Navy Repairman Manual and the Colvin and Stanley Book explain the fact that a perfect bevel gear cannot be cut on a mill but a close approximation can be produced thru manipulation. This is what Rich is explaining in the offset and rotation cuts. These are explained in both books but his fi...

Re: Seeking Knowlege on the Machining of a Bevel Gear.

Thank you for the input. My one confusion so far has been the mention of Special Cutters made specifically for doing the bevel gears. In the book, "Gear Cutting Practice" by Colvin and Stanly" there is the statement "Selection of Cutter for Bevel Gears- The length of the teeth on the face on the bev...

Re: 2.5 Inch Scale Boxcar From the Wheels up

Today was a practice retirement day. In and out of the shop for half of it. As I am making the trucks for five cars there are 60 bars that have to be bent and drilled. For this I made two jigs to bend them to that also serves as a drill guide. One is for the top twenty bars and the deep one for the ...

Re: 2.5 Inch Scale Boxcar From the Wheels up

All the wheels are machined and Painted. The journal boxes are fitted with lids and in the paint shop.

I ordered the steel for the Arch bars from Access Metals. This is all cut to length and I have started the bending and drilling for the ten trucks.

Another tedious task

Re: Chaski News and Support Request

Retiring soon but believe there will be a few loose coins floating around. Does Chaski have a PayPal account to which members could donate on a monthly recurring basis?
