Re: Drill press recommendations?

I’ve found the key with old drill press’s is to check the run out on the spindle. Old tired DP’s can have runout exceeding .010” due to bearing and spindle wear. Normal useage maybe under .003”. Like Mr. Ron, I found a really nice 1939 Delta DP that actually measures .001” runout. I use it all the t...

Re: Newbie - Buying first metal lathe

Iam with the bigger is better crowd. For all around hobby use, certainly for live steam locomotive building, a 12” lathe is extremely versatile, rigid and powerful enuf. Now days 14” lathes are also very very common. They are lighter weight than the old big iron lathes, but can often be found second...

Re: Woodinville Shops

Quick followup to the plastic workholding problem from yesterday. I decided to try to clean up my two plastic thrust washer disks today. So bolted then up on a threaded arbor on the lathe and turned the ends down to .300” thickness - just shy of 5/16”. However, The nut in the center left a noticeabl...

Re: Woodinville Shops

Got a piece of Hi Def Plastic to experiment making plastic thrust washers. Not sure if it is Delrin or lower grade HDFE. The scrap piece was formerly a bit of Boeing aircraft flooring - so high quality material, I am sure. machined up 4 thrust washers for the main bearing. Not much to see except a l...

Re: Woodinville Shops

Thanks Nyle, I think a couple of local metal working shops work a lot with Delrin. I’ll ask about and see if I can score a sample. Appreciate the info- I am not very knowledgeable about plastics...

Re: Boiler treatment

Russ, one followup question, regarding oxygenation. In your start up procedure, do you add anything that specifically scrubs dissolved oxygen from the water?

Thanks

Re: Woodinville Sho

More progress on the bearing. Finished turning the male side of the socket. Here it is, resting on the upside down frame. The bolster will be a full length piece of 3/8 x 4” flat bar, across the frame, welded to each sill. The male pin and retaining pin will be welded to a separate baseplate, simila...

Re: Boiler treatment

Russ, can you confirm that heating water in the boiler causes the dissolved oxygen to dissipate soon as the heat hits it? When you vent steam, are you venting all the dissolved O2? If so, what temperature/ pressure do you need to reach to first achieve this? How does this affect fresh water added fr...

Re: Boiler treatment

Important note: Terlyn Industries says LSB 8000 DOES NOT have an oxygen scanvenger additive. You need to add something for oxygen removal. Here is the text of an email reply I received from them: LSB8000 Locomotive Steam Boiler Treatment is typically used as a single feed product to control scale an...

Re: Woodinville Shops

Back on track with the flat car build. Last couple of days made up the top and bottom plates for the draft gear- coupler pockets actually. But the couplers have spring buffers bolted to the back of the coupler pocket. so I guess they are technically draft gear. Also finalized design for the main bea...

Re: Woodinville Shops

Hey Russ,

Great Jacket! This is exactly what I have. I just had it restitched and replaced some snaps, because it’s so old and well worn.

Would you believe the Great BonFire was the one time I didn’t wear it! True,

Anyways thanks for finding that link. Good welding jacket is essential

Re: Woodinville Shops

Yes, pretty amazing how hard it is to extinguish thick cotton clothing material. The hem on my pin strip work shirt was doubled over. The embers inside the hem wouldn’t go out. Keep burning like old dynamite fuse. Certainly an attention getter.
