Lane Ranger 11,458 #8777 Posted 17 hours ago (edited) Today i bought something I could not refuse! Lots of original parts in great shape ( and a few not that great like wheels but still with original tires and frint still loaded ). The seller was mowing with it when i went to look ( but i took my trailer) . I drove in third gear and accidentally hit the kill switch - still working! The Schnacke recoil, the rear hitch attachment connector, the showerhead muffler , an oil bath air cleaner with original decal, all the guards ( and belt guard had the original spacers with it) with no rust holes, a pretty early seat cushion, tight steering and a very good operating transmission snd motor! Somehow this survived 67 years. No crack on hood around gas tank. Gas tank very clean! yes the wheels have some rust and a few holes but tires all appear original to me. I think the decal ar back and the frame decal with # 12510 may be replaced decals but maybe that was the original #. I need a sixth RJ like a hole in the head but i got this on west side if Indianapolis near Raceway Road today! I am happy to have gone after it!

Trick is to keep all of the drills purpundicular to the surface. If you are drilling steel, oil while drilling helps reduce chatter. I had Marvel Mystery Oil handy, so that is what I used with the 3/4" holes saw today. 1 Share this post Link to post Share on other sites

The pilot drill broke through the material suddenly, then one side of the hole saw caught, pushing everything sideways. I drill a 1/4" hole first then go to the hole saw now. I bent/broke a few pilot bits before I figured that out. 2 Share this post Link to post Share on other sites

I did have, and always use, cutting fluid or oil for lubrication, cooling, and to contain the metal cuttings. Keeping the heat down, iMHO, helps extend the life of the drill bits. (Always the tradeoff between drill speed and feed pressure, of course!) 1 Share this post Link to post Share on other sites

(Always the tradeoff between drill speed and feed pressure, of course!) When I use a hole saw, I drill a 1/4” hole first and have a piece of 1/4” plain rod in the hole saw arbour in place of the drill bit. I’ve found that using the hole saw with the drill bit in the arbour, the flutes of the drill bit can cause the saw to chatter and wander until the cut has started. Using a plain rod instead of the bit prevents this from occurring 1 Share this post Link to post Share on other sites
