SCRAPING CLASS IN MECHANICSBURG PA FOR USA DEFENSE DEPT

[Richard King]

Hello All

It's early so forgive the short start of this tread. I start this class at 6:30AM EST. I'm not used to getting up so early. 6:30 is 5:30 back home. LOL
I'm working at a USA Navy Depot this week and teaching 15 students. 14 men and 1 woman. I will be adding photo's as the class progresses. Yesterday we finished up the basic instruction on how to Biax Power Scrape and today we start projects. Were scraping Starrett 199 levels soles, Surface plates, straight-edges, we are going to scrape a 36" Blanchard Grinder saddle. I'll write later as I have to scoot. Rich

Today after work I drove over to Walmart and bought several bodles of Craft paint, so tomorrow we can test it to see if we can find a cheap Canode Substitute. I did order some Charbbonel engraving in too. I know the Charbbonel works but, just doing some experimenting.

I was telling some folks, I started teaching here 20 years ago and all the Journeymen that rebuild the machines like the Jig Bore took my classes. DLA has me come in and teach the new hires as the Journeymen are to busy to teach the Apprentices. In this class I had I have a handful of Journeymen too that were hired 10 or less years ago and never learned to use the BIAX correctly. It's been a long week....one down, one to go. I'm staying over the weekend and tomorrow Im going to the USA's largest sportsman show held in Harrisburg. Some fun and relaxation...sighhh

One of my students rebuilds a lot of Monarch Lathes. He came up with this great idea for scraping the Tail-Stock sole plate. He milled 2 holes into a spare cast iron surface plate so he could blue up the top of the plate so later he can set it upside down on parallels to mill the worn bottom flat and V. We had to scrape the plate flat after he milled it. We are testing Red Charbonnel ink for the bluing. It works good.

I posted this in another thread, but this is a device or machine they use here to straighten gibs.
You measure the opening of the center section of the bent gib with feeler gages...3rd picture and then put that side up on the press and tighten the screw so you go by that number on the indicator and keep bending and releasing the screw until you get the gib straight. Then once it's flat with in .0005" you scrape the back or positive side to 5 to 10 PPI and ten scrape or put a wearstrip material on the wear side. They use Phenolic or Moglice here. They don't use a lot of Rulon or Turcite..

 

[Richard King]

I use the same technique, but my way is easier to carry in a tool box, I use a C-Clamp and an Indicator. Scroll to minute 5:25

Today was the 10 TH day and last of the class. Here is the class picture. 3 of the students aren't in it, I taught 15 this time. I have more photo's of what we accomplished and will add them later when I'm not so exhausted,

Next Month I have a class in IL and in 2023 I will be hosting classes in Minnesota. I had hoped to retire and go fishing, but I will be teaching classes until I die as I love teaching people my trade!
