The 1.5" OD tube is 1.25" ID which is really close to 32mm (31.75mm). If you really need 0.375" that is a different kettle of fish. Apparently it only needs to be around 2" long and the interior finish is relatively unimportant since you tried filing it. Try a powered reciprocating file. You can get them made to fit a recip saw or air tool. You probably don't want the little complete tools with the needle files.<br /><br />https://images.homedepot-static.com/productImages/0efb701a-9b5c-4a93-bee6-4073cd350b04/svn/reciprotool-drill-attachments-rct-hrm-10-64_1000.jpgJeffhttps://www.blogger.com/profile/12928963056168874465noreply@blogger.comtag:blogger.com,1999:blog-2807403883562053852.post-71369232967931978502021-07-20T22:32:31.049-06:002021-07-20T22:32:31.049-06:00You could take it to a wire edm shop and get much ...You could take it to a wire edm shop and get much sharper corners.

If the latter, build up with either weld or epoxy or something like that....Or use some setscrews and a plate.

If you don't know an engraver in the area, just take some 1/8" square key stock, cut an appropriate length and then put a 45 degree face across one end, oriented to give you a nice, sharp point.<br /><br />It will be a *terrible* graver but should be good enough for your use. Use a very small hammer to gently tap it down along the corner.<br /><br />The EngraversCafe.com forums have a lot of folks who can give you more info - and you might even find one in your area who can fix you up with a proper graver and tips.KCStevehttps://www.blogger.com/profile/03624297754874235871noreply@blogger.comtag:blogger.com,1999:blog-2807403883562053852.post-1450138081616239832021-07-20T15:24:27.752-06:002021-07-20T15:24:27.752-06:00Is 1.5" interior too excessive? https://www....Is 1.5" interior too excessive? https://www.grainger.com/product/GRAINGER-APPROVED-Square-Tube-6ALP5L T Hanleyhttps://www.blogger.com/profile/12498374697899881213noreply@blogger.com
