I haven't posted on this for a while so thought I would get you up to date.

Made the buffers for the buffer beams.

Started by making the bumper part of the buffers

I was stuck on how to form the convex on the face of the buffer until Tel's friend DrJ poited me to this site.

http://www.baggo.copperstream.co.uk/me/locos/25inch/helen%20longish/helen7.htm

Go about half way down the page to where he talks about the buffers. Worked really well.

Check out the rest of the site too. Tons of info on Locos. Zee you will love it.

I had to put packing in front of the headstock to get the right length of rod for the radius I needed
Thats the reason for the wood clamp in the pic. It's clamping the packing to keep it in place. This is
result.

Forgot to take pics of making the receiver part of the buffer. I made it in 2 pieces as I didn't have any square stock big enough to turn from. I think the 2 piece bit worked better anyway.

Checking fit of buffer into reciever.

Here is an assembly view

I mounted them on the buffer beams and tightened up the 3/8 nut on the buffer to hold everything in place and drilled the 4 holes in each square plate and buffer beams. Threaded the beams for 4-40 for 4-40 bolts. I am using round head machine screws to hold things now but I have scale hex head 4-40 bolts for final assembly.

On the frame temporarily.

Till next time.

Hi Ron, good start on that project, it's looking good so far. It's been a long time since I've seen someone use the pin and packing method for getting a good, repeatable radius. It looks real fine on those bumpers, and you can get a good repeatable concave radius if you put the pin between the carriage and the tailstock, I've got half a dozen "center pops", on both sides of the carriage and on both head and tail stock for pins. Those frames look nice too, crisp and on size from the pictures, personally, I like to rivet when ever possible, it makes a stronger joint than a screw can ever imagine, and when it goes right, it's quick and easy, and one can set quite a few rivets pretty fast, just going down the line. I'm looking forward to the putting together of the more intricate parts, in and all around the frames. Great Start, ought to be something to see run when it's done. :jaw:mad jack

Thanks madjack, I riveted the angle brackets for mounting the beams on the frames. Thats why they are primer painted. I had to fill all the dings and bruises from the hammer. :( :( :( I forgot I still have to mount some 1/2 x1/8 anlgle to the beams to support the running boards so I will probably have more dings to fill. :hammer: :hammer: :hammer:

Very nice Ron, I saw someone using that technique for the first time at harrogate exhibition last year.
