clay lover Posted December 31, 2014 Report Share Posted December 31, 2014 Does anyone have any advice before I stumble through this? I have the squares of material I want to use and a new factory drilled bat to use as a template. What size bit do I use, and how do I get the oval hole correct? I would hate to end up with holes too big, <_<all though I guess I could then rotate the bat and drill another set of the correct size and placement .

Mark C. Posted December 31, 2014 Report Share Posted December 31, 2014 Are you drilling a bat or a wheel head??? this will determine hole size. Are these standard bat pins? with 3/8th heads?? More Details on a detail job please. Mark Link to comment Share on other sites More sharing options...
oldlady Posted December 31, 2014 Report Share Posted December 31, 2014 don't bother with an oval hole. just round ones. i did several with 6 hole sets before i gave up and had a pro carpenter do them. (it is hard to throw without getting a finger stuck in the wrong holes when there are so many of them.) Link to comment Share on other sites More sharing options...

clay lover Posted December 31, 2014 Author Report Share Posted December 31, 2014 So sorry, the title is not correct, it should say, "how to drill pin holes in BATS I have 8" squares with no holes and want to put holes in them to use them on my T S wheel head with bat pins.

Mark C. Posted January 1, 2015 Report Share Posted January 1, 2015 Most bat pins are 3/8-use a drill press-make sure they are wll marked-you can center punch them for accuracy. I would use the next size larger only with a letter drill set-If this is all an unknown have someone else drill them who knows this. If you do not have a letter drill set (these have more sizes than standard drill sizes) you can ream them out tad with a hand 3/8 th drill after you use the 3/8th drill in a drill press.The next size up can be sloppy in a normnal dril set. The main thing is getting the layout right.I like a tight fit without slop bt thats me. Mark Link to comment Share on other sites More sharing options...
oldlady Posted January 1, 2015 Report Share Posted January 1, 2015 repeat.... to a real carpenter this is a simple thing to do. when i took my 4x8 sheet of Duron to the expert, i wound up with a huge stack of perfectly formed circles with perfect holes in exactly the correct places, cost maybe $20. it is true that being a potter is only for masochists but why bat your head against a minor problem when you could be trying to do something really impossible, like posting pictures here!

schmism Posted January 3, 2015 Report Share Posted January 3, 2015 real carpenter here and I will confess, it is simple for me. I drill the holes for the bat pins before I make the bats round as I set the sq bats on a jig I made to route the bats round. This assures that each bat will fit on a set of 10" x3/8 pins.I dill mine 3/8. I mark a center line then offset 5" to both sides (making shure the overall is 10" as that is more important than true 10" OC as when I route them round they will always be OC) I clamp a stack usually about 4" of batts together then drill all of them with a brad point drill bit on my drill press.

flowerdry Posted January 13, 2015 Report Share Posted January 13, 2015 I just got done drilling a bunch of existing plywood bats with the old 8 something inch offset. At our community art center where I teach, we only have 1 wheel with the old style bat pins and I found a pile of bats drilled to fit that one wheel. I took a sample bat, used a center punch to mark the holes to be drilled, then at the recommendation of someone who knows carpentry, used a fosner bit to drill the 3/8" holes. That type of bit keeps the wood from splintering around the holes. Worked great. Happy drilling. Link to comment Share on other sites More sharing options...
Mark C. Posted January 13, 2015 Report Share Posted January 13, 2015 forsner bit to drill the 3/8" holes-its the only way to go. mark Link to comment Share on other sites More sharing options...
