I have a Whirly Jig I loaned out , and they lost the pipe to tie the bases together . It was over 20 years ago when I bought it and used it . I am rehabilitating it and selling it locally to a friend . Is that base pipe supposed to be 2 inch schedule 40 ? I also need to get a new set of instructions I have not been able to get in touch with the manufacturer . I would pay for a copy on a memory stick if you could make one TJP . Thanks , Ron
