D1-3 Backplate
Steenkamp:
Compliments of the season to all. Yesterday i remembered about a piece of cast iron i aquired a while ago
So the big measure started
After lots of carefull measurement i started by chucking up the cast iron in the four jaw and flattened one side. This would enable me to mount it directly to my current backplate
Steenkamp:
After flattening the plate i proceeded to drill and tap the plate to fit my scroll chuck hole thats already made on my original backplate. This enabled me to bolt the new backplate directly to the original
The reason i fitted the new plate directly to the original will become evident later on....
I then flattened the other side and proceeded to cut a slightly raised boss that will register against the spindle nose i also bored the through hole
Steenkamp:
I removed the whole assembly and set my compound slide over to the correct taper using a finger guage and very carefull tapping with a soft hammer. Sorry , i didnt take any pictures as i was concentrating very hard to get it right.
I remounted the assembly. The reason i mounted the cast iron plate to the original backplate is that i can very accurately and repeatedly remove and measure fit the new backplate against the spindle nose. I then proceeded to cut the taper and when i got to size i removed the assembly, blued it up, test fitted and took minute cuts, repeatedly.... Till it fitted perfectly
Thats how far i got last night. Will continue this arvie and hopefully finish up

I'm sure it's all very nice work, but I suspect I'm not alone in not being able to see your pictures properly as they are so huge. 640 x 480 is a good compromise between detail and screen size, and let's people view your work without having to scroll all over the place
Steenkamp:
My apologies. Sent them from my phone. Will adjust the size next time
