    Thanks for the kind words Crahar. I do that sometimes too, or lay things out in an order that works for me. This was a case of calibrated finger torque and guess I wasn't paying enough attention putting it back together after the clean up so it caught me off guard.

    Thanks PJ

    The drill has about a foot of height adjustment altogether, 6 inches from the quill and 6 inches on the cast dovetail ( originally some of these had a half ton cast base with the table that was nothing like today's tables. The small wheel on the front is for adjustment of the belt tension. These had leather line drive flat belts originally, a previous owner got creative with the pulley setup. The adjustment wheel moves the motors sled. If you ever come across one save it if you can. They sell from most industrial auctions online for scrap value often. Mine only has an old ˝hp motor but it will go through steel plate like its butter, and very quietly too.

    Good idea on using the pinch clamp bolts, that looks like a perfect spot! I have a pile of those coupons too

    Very cool details, Jere. I thought that idler looked a little odd, like an add-on, but still very cool to be able to adjust or change belts from the front. My Dads old radial head was quite too, probably all that Iron! You can bet your boots if I find one I'll snag it!

    HFT runs those 6" calipers on sale <$10 all the time but recommend opening a few and taking the best one...some are rough as cobs. Seems like a natural place with bolts available...glad to help. Look forward to what you come up with!

    That's a nice and clean mod, PJs. My kind of build. I like your use of a simple worm clamp as a fixing band for the sliding scale.
